Choosing bathroom tiles: a 2026 buyer’s guide for luxury renovations

01 · Material

Porcelain vs natural stone vs marble vs ceramic

Almost every tile decision in a UK luxury bathroom comes down to four materials: porcelain, ceramic, natural stone, marble. The look you want narrows the choice. The maintenance reality and the budget close it. All four behave differently in a wet room, age differently over a decade, and price differently per square metre. Most of the regrets clients bring us would have been avoided if they’d understood the material before they fell for the visual.

Porcelain is the workhorse of the modern luxury bathroom. It’s fired denser than ceramic, at around 1,200°C, and water absorption comes in under 0.5% (BS EN 14411 Group BIa, the European tile standard). That makes it the one tile that stays happy under direct water indefinitely. Stone-effect, marble-effect, concrete-effect, terrazzo-effect, wood-effect: those ranges have closed the visual gap with the materials they imitate. On a luxury scheme today, a good porcelain stone-effect from Porcelanosa or Ca’ Pietra is hard to tell from honed limestone at arm’s length. There’s a catch, though. The closer porcelain gets to looking like real stone, the harder those ranges are to source, which is why we lean on the designer-grade brands: their catalogues carry the depth of veining you want.

Ceramic is porcelain’s less-fired sibling. Water absorption is higher: 3–6% in Group BIIa, 6–10% in BIIb and above 10% in BIII (BS EN 14411), so in a wet bathroom we keep ceramic on the walls and off the floor. It’s lighter, easier for a tiler to cut, and a bit cheaper per square metre. Where ceramic really belongs in a luxury bathroom is hand-decorated, hand-glazed and zellige tile. No porcelain factory can replicate the irregular glaze pool of a hand-thrown Moroccan zellige, or the hand-painted figuration of a heritage range. So: ceramic for the back wall behind a freestanding bath, where the tile is the moment; porcelain for the floor, where the tile is the substrate.

Natural stone (limestone, travertine, slate, marble) is what separates a designer-grade bathroom from a catalogue one. It’s a real geological material; no two pieces are identical; the colour develops over decades. It’s also more demanding. Limestone and travertine need impregnating sealer at install and a top-up roughly every six to twelve months, marble doesn’t like acidic cleaners (anything citrus-based etches the surface), and slate sheds slightly through the first six months as the surface settles. In a hard-water area like much of Essex, stone wants a softener on the cold supply to the wet zone. Otherwise the limescale cycle that we cover in the bathroom designer guide works on your tile as well as your tap. Plan for that maintenance and stone is the most beautiful surface in the bathroom inventory. Skip it and stone is the most regretted.

Marble is a natural stone we treat as its own category, because the spec conversation is different. Marble in a bathroom is the visual statement. You don’t use it as a default substrate; you use it where you want the eye to land. The right marble bathroom is restrained: one feature wall, one shower floor, one vanity-top run. The wrong one puts cheap marble everywhere, cut for no particular application, and you can spot it inside a year when the veining has dulled and the surface has lost its lustre. We specify marble through Ca’ Pietra and the natural-stone houses for a reason. Their slabs are cut for the application and dye-lot-coordinated across a single project; the trade-counter equivalents aren’t. Have a look at what a marble bathroom costs for real tile and slab pricing before you specify it.

02 · Format

Tile format: large-format vs metro vs mosaic

Format is the second-biggest decision after material, and the one that most affects how a finished bathroom feels once you’re standing in it. A 1500×750 mm large-format porcelain lands completely differently to a 75×150 mm metro, even with identical colour and finish. Format is what separates a calm, modern luxury scheme from a busy traditional one. Get it wrong and you end up with clutter where the brief asked for calm, or a bare, cool room where the brief asked for warmth.

Large-format, meaning anything 600×600 mm and up, is the dominant move on contemporary luxury bathrooms in 2026. The visual logic is simple: fewer grout lines, calmer and more expensive-feeling surface. Porcelain slab products at 1200×600 mm and 1500×750 mm are mainstream now from the major designer-grade suppliers, and the true slab format runs to 3000×1500 mm and beyond. It also makes a room look bigger than it is. A small ensuite floor in 600×600 mm porcelain looks larger than the same room in 300×300 mm, because the eye treats grout lines as interruptions and quietly counts them. Installation is where you pay for it: large-format wants a perfectly flat substrate, full bed adhesive (no spot-fixing), and a tiler who has done it before. We see fitter day rate go up roughly 20–40% over a standard 300×600 mm spec, and the wastage allowance climbs too. We cover the wastage maths in our tile quantities and waste guide.

Metro is the rectangular 75×150 mm or 100×200 mm shape that has run UK bathrooms since the 2000s, and it’s still the go-to for traditional, period-property and heritage schemes. It carries the visual reference to Victorian and Edwardian municipal bathrooms. It suits panelled rooms, freestanding baths with claw feet, and brassware in chrome or polished nickel. The 2026 evolution is the longer, narrower metro at 50×200 mm or 65×260 mm, which keeps the period reference without the dollhouse scale of the original 75×150 mm. Metro is also where layout decisions matter most. A brick bond, a herringbone and a stack-bond give you visibly different rooms from the same tile, and we’ve gone through that decision in our tile layout ideas guide.

Mosaic is the third format, and the most underused on luxury bathrooms outside the designer-led showroom world. Used right, it’s the texture moment that lifts a scheme: a marble mosaic feature wall, a penny-round shower floor, a fish-scale border behind a vanity. Used wrong, it’s busy, dated and impossible to keep clean. Our rule is mosaic for the moment rather than the whole room. A 25 mm penny-round porcelain mosaic on a level-access shower floor solves the slip-rating problem through sheer grout-line density (more grout lines, more grip) and looks intentional doing it. A 25 mm marble mosaic on every wall of a small ensuite looks like a Pinterest accident.

03 · Finish

Tile finish: matt vs gloss, honed vs polished

Finish is the third axis after material and format, and it’s where most of the bathroom’s maintenance reality lives. The same tile in matt and in gloss behaves completely differently in a hard-water area, photographs differently, and ages differently over a decade. Match the finish to how the surface gets used. The photo on the supplier’s website is always the most flattering finish under controlled studio lighting, which is a different question altogether.

Matt finish on porcelain or ceramic gives you a soft, low-glare surface that hides water spotting. That’s what makes it the safest choice in a hard-water area. Limescale residue still forms, but it doesn’t catch the light the way it does on a polished surface. Matt is the right call for floors almost universally, and for walls in a contemporary or quiet-luxury scheme. It’s harder to clean, though, because the same texture that hides water spots also catches grime, so a matt tile in a heavily used family bathroom wants a more attentive cleaning routine than the same tile in a guest ensuite.

Gloss gives you the high-shine, light-reflective surface that makes small bathrooms feel bigger and dark schemes feel less heavy. It cleans easily; a wipe with a damp microfibre takes care of most of it. But it shows water spotting plainly in hard-water areas, and that spotting turns to limescale within a few weeks if nobody dries the tile after use. So gloss for a guest cloakroom, a small ensuite, or a feature wall behind the basin where the light bounce is the whole point. On a wetroom floor, almost never. The slip rating drops and the upkeep bites.

Honed is the natural-stone equivalent of matt: the stone is ground flat and given a soft, low-sheen surface. Honed limestone, honed marble and honed travertine are the standard luxury-bathroom specs because they hide water spotting, hide minor imperfections in the stone, and don’t fight the light the way polished stone does. Unless the scheme is deliberately period-formal, honed is what you want on stone floors and stone walls.

Polished is the high-gloss stone finish: a polished marble feature wall, a polished travertine vanity top, a polished granite shower bench. Save it for the moments where the visual impact justifies the upkeep. Polished marble in particular is etched permanently by anything acidic, whether that’s citrus juice, vinegar-based cleaners or even some shampoos, so it belongs on surfaces that won’t get splashed with the wrong thing. We almost never put polished stone on a UK bathroom floor. The slip rating drops to R9 or below, and the upkeep turns it into a regret within two years.

04 · Slip rating

Floor slip rating: R10, R11 or R12?

Slip rating is the spec line most homeowners don’t know exists, and the one that causes the most heartache when it gets missed. A wet shower floor in a tile rated R9 is properly slippery. The same room in R11 is fine. The gap between R10 and R11 in a wet zone is small at the order stage and large once people are living in the room. We treat slip rating the way we treat IP rating on light fittings: non-negotiable in the wet zones, and one of the first questions we ask on any tile spec.

The standard quoted on UK tile spec sheets is the German DIN 51130 wet-shod ramp test. It produces R-ratings from R9 to R13 based on the angle at which a walker in safety boots starts to slip on an oiled ramp. R9 covers slip angles of 6° to 10°; R10 10° to 19°; R11 19° to 27°; R12 27° to 35°; R13 above 35°. In a domestic bathroom, R9 belongs in a dry hallway. R10 is the minimum for a standard bathroom floor outside the wet zone, R11 is what we specify in the wet zone of a level-access shower or a wetroom, and R12 is for properly steep or commercial settings. You won’t need R13 in a domestic spec.

You may also meet a second scale on UK product specs: the Pendulum Test Value (PTV), measured per BS 7976. PTV is what the UK Health and Safety Executive prefers for commercial and public-sector floor slip-resistance assessment. The domestic trade defaults to the German R-rating instead, because that’s what the European tile factories print on their data sheets, so on a private residential project it’s the figure your designer and your tiler will both work from. If a spec sheet gives you only PTV, don’t try to translate it into an R-rating. HSE’s guidance sheet, Assessing the slip resistance of flooring, gives no conversion between the two scales, and it says floors classified R9, and in some instances R10, will be slippery in wet conditions. Read a PTV against HSE’s own bands instead: 36 and above is low slip potential, 25 to 35 is moderate, and 0 to 24 is high. For a shower floor, ask the supplier for the figure measured wet.

In a level-access shower, where the slip risk is real, we specify R11 minimum on the shower floor itself and R10 on the surrounding floor. The most reliable way to hit R11 in a luxury scheme is a small-format porcelain mosaic, where the grout-line density adds grip independently of the tile face. A 25 mm penny-round porcelain mosaic does that beautifully, and it looks like a deliberate design choice rather than a compromise. The alternative is a textured large-format porcelain rated R11 at the factory. Every major designer-grade supplier offers R11-rated stone-effect ranges for exactly this job, and they look flat from arm’s length while gripping underfoot. Riven slate in its natural finish will often clear R11 with no treatment at all, which is why Ca Pietra Metropolitan Slate turns up so often in level-access shower zones.

Here’s the one that turns into a regret. Someone specifies a polished marble floor in a wetroom because it photographs beautifully on the showroom display. The R-rating drops to R9 or below, the floor is slippery when wet, and the homeowner spends the next decade nervous of their own shower. Honed marble at R10 is fine in a dry zone. For the wet zone of a level-access shower, push to R11 or split the floor into a marble dry zone and a mosaic wet zone where the format solves the slip rating for you.

05 · Grout

Grout colour discipline (and the hard-water trick)

Grout is the line item most homeowners forget on the spec sheet, and the first thing the eye notices when a bathroom looks tired. Get the colour right and a £40-per-square-metre tile passes for a £100 tile; get it wrong and the £100 tile looks like a tired Travelodge. Colour is also the biggest hard-water lever you have. Across Essex and most of the South-East, mains water runs at over 250 mg/l of dissolved calcium carbonate, which is properly hard water by Drinking Water Inspectorate definitions. So the grout you choose decides whether the bathroom ages well or needs a deep-clean every three months.

The mid-grey or sand-tone rule. In any hard-water area, mid-grey or sand-tone grout masks dirt and limescale residue together. The off-white film that builds up on grout in hard water sits at roughly the same tonal value as mid-grey or warm sand, so it disappears into the colour instead of contrasting against it. Pure white grout shows limescale faintly within months and obviously within a year. Black grout shows the white lines within weeks. Those two colours are the only ones we specify by default for floor and wet-zone tile in hard-water postcodes, and they go on the spec sheet the same day the tile does. They aren’t an afterthought for when the tiler asks in week three.

The dark-grout exception. Where the tile itself is dark, think emerald green metro, navy zellige, charcoal porcelain, the grout needs to sit as a continuous tonal field with the tile. That means dark grey rather than black. Dark grey still picks up some limescale film in a hard-water area, but the contrast is far lower than black grout against the same tile. True black grout is a call for soft-water areas, much of the North and West of the UK, where limescale build-up isn’t the thing that ages a bathroom.

The white-grout exception. White grout is fine in soft-water areas, fine on dry-zone wall tile, and fine in any feature where the grout-to-tile contrast is the design intent, like a black-and-white penny-round mosaic on a guest cloakroom floor. The combination to avoid is white grout in a wet zone in a hard-water area. You’ll be cleaning it every week.

The softener-as-grout-protector trick. A whole-house water softener, typically £1,200–£2,000 installed, takes limescale build-up off the tile, the grout, the brassware and the inside of the cylinder. On a luxury project where natural stone, polished brassware and dark grout are all part of the design intent, a softener will usually pay for itself in three to five years through reduced replacement and re-grouting. We recommend one on roughly 70% of the luxury bathrooms we specify in Essex. The homeowners who say no and then go ahead with dark grout, polished brass or natural stone tend to regret it inside two years.

Bowmans settles the grout colour at the same showroom appointment as the tile, so the spec sheet that reaches your fitter carries the grout RAL or supplier code rather than the word “mid-grey”. Your fitter then orders a known product instead of interpreting an instruction.

06 · Marble

Book-matching marble — the slab move that lifts a scheme

Book-matching is the marble specification that marks out a designer-grade bathroom. It’s worth knowing about even if you never specify it. Once you’ve seen it done well, you can tell at a glance which marble bathrooms were designer-led and which were not.

The technique is straightforward enough. Two slabs of marble come off the same block, the second cut as the mirror image of the first. Open them like the pages of a book, lay them side by side, and the veining runs across the centreline as a perfect mirror. Used as a feature wall behind a freestanding bath, behind a vanity, or in a walk-in shower, you get a single visual moment that looks natural and inevitable rather than tiled and assembled. Done well, it’s the most photographed feature in the room.

The cost premium over standard marble is more modest than most homeowners assume. The slabs themselves cost roughly what standard slabs of the same stone cost, because what you’re buying is the cut sequence rather than extra material. The premium sits in the installation labour. The layout has to be drawn before any cut is made, the slabs have to be sequenced from the block at the supplier’s yard, and the tiler sets out the centreline first and works outward. In our experience the total premium over a non-matched marble feature wall runs £600–£1,800 on a luxury bathroom, depending on slab size and stone choice. The visual impact is out of all proportion to that.

Where book-matching works: a feature wall behind a freestanding bath; the back wall of a walk-in shower; the splash wall behind a wall-hung vanity; the tall wall in a small ensuite where one moment carries the room. The common factor is a single flat surface with a clear centreline.

Where book-matching doesn’t work: a wall with a window, a wall with a recessed niche, a wall that wraps a corner, or a wall where brassware or shelving interrupts the run. The whole effect depends on visual continuity across the centreline. Break the centreline and you break the effect.

Ask about the marbles whose veining is dramatic enough to make book-matching worth the labour. Calacatta Viola, Calacatta Borghini, Verde Alpi, Rosso Levanto and the heavily veined stones in the Ca’ Pietra natural-stone catalogue all repay it. The plainer marbles, Carrara and plain Calacatta, are still beautiful. The premium is just harder to justify on them, because the centreline comes across as subtle rather than dramatic.

Lead time on a book-matched marble feature wall is the longest in the tile category, roughly eight to twelve weeks from order, because the slabs have to be sequenced from one specific block at the supplier’s yard and shipped together. Order before strip-out begins, and order sure of the stone. You can’t swap mid-project the way you might with a standard porcelain.

07 · Lead time

Lead times — why special tiles need 6–10 weeks

The most expensive miscalculation on a luxury bathroom project is starting the strip-out before the tiles are confirmed in stock. Tile lead time decides when your fitter can start; your fitter’s diary doesn’t decide the tile. And lead times on designer-grade and natural stone ranges run longer than homeowners expect. Order before strip-out applies to every product line in a luxury bathroom, but tiles are the one that catches people.

Mainstream porcelain from the major trade-counter and online suppliers ships in one to three weeks. This is the inventory-held end of the catalogue, full pallets sitting in a warehouse: standard sizes, standard colours, factory-stock SKUs. It’s the right option for a like-for-like swap or a renovation on a tight programme.

Designer-grade porcelain from Porcelanosa, Ca’ Pietra and the boutique European suppliers typically runs three to six weeks on confirmed-stock ranges, and longer on special-order. The premium ranges are made to order in smaller batches. A supplier holds enough for sample boards and confirmed projects; walk-in retail quantities aren’t sitting there waiting. Plan around it.

Natural stone (limestone, travertine, slate, marble) is six to ten weeks typical, and longer for book-matched slabs at eight to twelve weeks or for special cuts. The stone has to come out of the quarry, get dressed at the supplier’s yard, and ship on a dedicated pallet because of the weight. Stone is also where dye-lot consistency matters most. Ordering early lets the supplier sequence the slabs from a single block, which is why the natural-stone catalogues stay quietly conservative about lead-time promises.

Hand-decorated and zellige ceramic is eight to fourteen weeks. Every tile is hand-thrown or hand-painted, the kiln runs are smaller, and the irregular finish that justifies the premium justifies the wait as well. On hand-decorated projects we tell clients the design locks at the appointment that orders the tile. There’s no revising it on a fortnight’s notice.

Mosaic ranges sit between mainstream porcelain and natural stone at three to six weeks, longer for stone mosaic where the chips are cut from real material. Specify mosaic for a level-access shower floor early, because that tile drives the floor build-up underneath it.

What we tell clients on day one of any luxury bathroom project is this: the tile order goes in before the fitter is booked. Get the tile confirmed in stock, get the lead time in writing from the supplier, and book your fitter to start one week after the latest expected delivery. Strip-out happens the day the tile arrives. It’s dull sequencing, and it’s what protects you from the most common preventable failure in a UK luxury bathroom: an empty stripped room, the fitter on day rate, and the tiles still somewhere between Italy and Essex.

08 · Brand

The Ca’ Pietra ranges worth knowing

Ca’ Pietra is the British natural-stone and ceramic tile house we recommend more often than any other supplier on luxury bathroom projects. It’s family-owned, it began in Devizes in Wiltshire, and the catalogue runs from French limestone slabs through hand-glazed ceramic to large-format porcelain. That combination of designer-grade material and sensible lead times is rarer than it sounds. The ranges below are the ones we specify most often, and the names worth having in your head when you read a designer’s spec sheet or ask a showroom what they hold in stock.

Cote Bourgogne French limestone. This is the warm-cream limestone we put on floor and wall when the brief calls for natural stone in a quiet, classical scheme. Honed finish, large-format options to 600×900 mm, R10 standard. Sealed at install, with a top-up sealer every six to twelve months.

Athens Amazon. A hand-glazed ceramic in a soft sea-green, with the irregular glaze depth that porcelain factories can’t replicate. A feature wall in Athens Amazon behind a freestanding bath is the textbook case for choosing ceramic where you’d otherwise default to porcelain.

East Java marble mosaic. A small-format marble mosaic built for level-access shower floors and feature walls. The grout-line density gives you R11 underfoot in the shower zone, and the marble itself comes across as one material moment rather than a tiled surface. On most luxury wet-zone schemes we pair East Java on the shower floor with a complementary large-format porcelain on the wall.

Hollywood Blue Linara. Soft mid-blue ceramic in a hand-decorated finish, a feature tile for panelled and traditional bathrooms where the colour is part of the design intent. The finish looks crafted rather than catalogue, which is the whole point of the Linara range.

Long Island marble scallop. Sculptural marble cut into a scallop shape, used as a feature wall or a behind-vanity moment. Because the shape carries the visual interest, the marble underneath can be a quieter Carrara or honed Calacatta and the wall still looks designer-grade.

Metropolitan slate. Riven natural slate in dark slate-grey, where the texture delivers an R11 slip rating without any treatment at all. We specify it on level-access shower zones and wetroom floors where the brief is contemporary or minimal, because the material handles the slip rating and the visual restraint in one go.

Palazzo Oro. Warm gold-toned tile, usually laid in a brick-bond pattern, made for a feature wall or a focal point above a vanity. The tone shifts under different lighting, so we always ask clients to sign the spec off under both daylight and evening LED before committing.

The full Ca’ Pietra catalogue runs to several hundred ranges across natural stone, porcelain, ceramic and concrete. The names above are simply the ones we lean on most. Our Ca’ Pietra range page covers the broader catalogue, and the showroom holds full-tile and full-pattern samples of every range named here, so you can judge format and finish at the size you’d specify.

Pricing across the Ca’ Pietra ranges varies enormously by category. The porcelain stone-effect ranges sit at £40–£90 per square metre, natural stone at £80–£200 per square metre, and the hand-decorated and book-matched marble lines can clear £300 per square metre. On every quote we benchmark those prices against the major UK online retailers, meaning Drench, Tile Mountain, Walls and Floors and the supplier-direct sites. Section nine picks that up properly.

09 · Pricing

How tiles are priced — and where Bowman benchmarks

Tile is the biggest single line item on most luxury bathroom budgets, which makes it the biggest place to save money or get quietly overcharged. The market splits cleanly into three tiers, and each one prices on a different logic.

Online retailers such as Tile Mountain, Walls and Floors, Drench, Victorian Plumbing and the supplier-direct sites sell mainstream porcelain and ceramic at the lowest list prices in the UK. They run inventory at scale, ship in a few days, and earn margin on volume rather than service. What you see is what you get. You place the order, the tile arrives, and anything that turns out wrong (the dye lot, the wastage allowance, the slip rating for your application) is yours to sort out. For a like-for-like swap on a standard rectangular bathroom, online is the right answer.

Margin-funded designer-led showrooms are the most common UK luxury model. They carry the same brands as the online retailers, plus the boutique designer-grade ranges the online retailers don’t stock. On the overlapping ranges, list prices sit a bit higher, because the tile margin is what pays for the design service. That’s the industry standard, it produces excellent design, and there’s nothing wrong with it as long as you know the design is being paid for through product mark-up.

Online-priced designer-led showrooms are rarer, and that’s where Bowmans sits. We benchmark our tile pricing against the major UK online retailers on every quote we issue. The design service, the slip-rating verification, the lead-time coordination, the dye-lot sequencing and the spec-sheet documentation are all value the business absorbs rather than a cost folded quietly into list prices. You pay roughly what the same brands cost online, and the design comes with it.

Put this to every showroom you visit, ours included. Ask directly how their tile pricing compares to Tile Mountain or Drench on the same product. A specific answer (“we’re within 5% on porcelain and within 10% on the boutique stone ranges”) tells you the showroom is open about its model. A vague one (“our tiles are higher quality”, “the comparison isn’t like-for-like”, “you get what you pay for”) tells you the design service is funded through margin and they’d rather you didn’t ask. Both models can be straight with you. The one to walk away from pretends the design costs nothing without saying where the cost actually lands. If quality is the answer you get, our guide to whether expensive bathroom tiles are worth it shows what to check on the tile itself.

Curious where your own tile spec lands across a whole bathroom budget? Our interactive product price guide takes a brief covering sanitaryware, brassware, tile, vanity and finish level, then hands back an investment range on the spot.

10 · Pitfalls

Tile mistakes a designer prevents

Most tile regrets have nothing to do with taste. The look was right; the spec was wrong for where it went. The five below come up again and again on UK home renovation forums, and a designer-led showroom catches all of them in the first appointment.

11 · Budget

Tiles as a share of the bathroom budget

For most luxury bathrooms in 2026, tiles run somewhere between 15% and 25% of the total project cost. That makes them the biggest product-line spend in the room. Where you land inside that band depends on the spec, the format, and how much natural stone is involved.

On a £15,000 entry-luxury bathroom, tiles typically take £2,000–£3,500 of the total. That buys mainstream porcelain on floor and walls at £40–£70 per square metre supplied, a mid-grey or sand-tone grout, and one feature wall in a more characterful porcelain or hand-decorated ceramic.

On a £25,000 standard luxury bathroom, tiles run £4,500–£7,000. Designer-grade porcelain goes on the floor at £70–£100 per square metre, with a feature wall in marble-effect porcelain or hand-decorated ceramic and a mosaic moment on a level-access shower floor or behind the basin.

On a £40,000+ bespoke principal suite, tiles can clear £8,000–£15,000. Real natural stone on floor and walls, a book-matched marble feature wall, hand-decorated ceramic on a feature surface, and a small-format marble mosaic in the level-access shower zone. All of it dye-lot-coordinated across the project.

Our UK luxury bathroom cost guide breaks down where the money goes at each tier, with line-by-line specs at £15k, £25k and £40k+. The tile share holds steady at 15–25% across all three. That’s why the tile spec moves the budget further than almost any other decision you make.

So the tile is roughly a fifth of a luxury bathroom, and it’s the line where a designer-led showroom adds the most measurable value: slip rating verified, grout colour locked, lead times sequenced, dye-lot coordinated, layout wastage calculated. Get any one of those wrong and the bill usually exceeds what a margin-funded showroom would have charged for design in the first place. At Bowmans the design is included alongside online-benchmarked product prices, and that’s the case we make for booking an appointment.
