“We were told six weeks. It took eighteen.” A version of that sentence lands on Mumsnet most weeks, in the Houzz UK forums constantly, and in our showroom inbox more often than we’d like. The answer is more interesting than “six weeks” or “eighteen weeks”: it depends on what you’re specifying, and the bit homeowners always underestimate is product manufacturing time rather than site work. Here’s the real 2026 schedule, week-by-week, broken down by phase.
01 · The schedule
A 2026 luxury bathroom timeline runs in four sequential phases, and they don’t overlap much: design has to finish before order, order has to (mostly) land before strip-out, and strip-out has to finish before second-fix. The whole clock runs 12–24 weeks for a standard luxury project and 18–28 weeks for bespoke. Below is the schedule we work to with clients. Yours will sit somewhere on that scale depending on the spec.
Standard luxury bathroom · 16–18 week mid-range schedule
| Week | Phase | What happens |
|---|---|---|
| Week 1 | Design | First showroom appointment — brief, brand walk-through, rough budget calibration. |
| Week 2 | Design | You measure the room with our step-by-step guide. Sizes, ceiling heights and photos of soil pipes and the water system sent over. |
| Weeks 3–4 | Design | Draft CAD layout and 3D render. First review meeting. Revisions round one. |
| Week 5 | Design | Final spec sheet. Sign-off and quote. |
| Week 6 | Order | Deposit paid. Orders placed across all brands the same day. Long-lead items first. |
| Weeks 7–13 | Manufacture | Products in factory queue. Brassware, sanitaryware, stone, joinery in production. Nothing happens on site. |
| Week 14 | Delivery | Goods-in. All product checked against spec sheet before strip-out begins. |
| Week 15 | Install | Strip-out, first-fix plumbing and electrics, screed or tanking. |
| Week 16 | Install | Tiling, second-fix plumbing, sanitaryware install, brassware fit. |
| Week 17 | Install | Joinery, glass, mirrors, lighting, snagging walk. |
| Week 18 | Handover | Grouting cure, silicone, final commissioning, handover and aftercare brief. |
Indicative 16–18 week schedule for a standard luxury bathroom in 2026.
Notice the shape. Of an 18-week clock, only weeks 15–18 are on site; weeks 1–5 are the showroom and the drawing board, and weeks 6–14 are factories in Italy, Germany, and Yorkshire. Design and order together come to 10 weeks, which is more than double the 4 weeks on site. That ratio surprises most homeowners, and it’s where timeline disappointment starts: they underestimate the manufacture phase and fixate on the install.
That base schedule flexes two ways in practice. Compressed luxury (12–13 weeks): stock-finish brassware (chrome from Crosswater Union or Hansgrohe Logis), porcelain rather than stone, off-the-shelf sanitaryware (Catalano Zero or Sfera in white), no joinery. Nothing here is bespoke, so the order phase shrinks to 6–7 weeks. Bespoke principal suite (22–28 weeks): book-matched stone slabs from Ca’ Pietra, special-finish brassware (PVD bronze, brushed nickel) from Hansgrohe Axor, custom joinery, smart WC. Here the order phase stretches to 14–18 weeks, because you’re queuing at a factory for items nobody keeps on a shelf.
If you want a deeper read on the cost side of these tiers, we’ve broken it down in our UK luxury bathroom cost guide. The timeline figures here pair directly with the spend figures there.
“The biggest single delay isn’t the fitter. It’s the brassware factory in Germany.”
02 · The shape
Every luxury bathroom runs through four phases in order. Skip one or squash one and you get the most common cause of slippage we see. So here’s what each phase is, and why the sequence matters.
Phase one · 3–6 weeks
Design and specification
First appointment, room measurements, CAD layout, 3D render, full specification sheet, sign-off and quote. 8–15 hours of designer time. Two to three revision rounds is normal. End-state: a complete spec sheet of every product down to silicone colour.
Phase two · 6–14 weeks
Order and manufacture
Orders go in across every brand on the day of sign-off. Special-finish brassware 8–14 weeks, bespoke stone 6–10 weeks, European sanitaryware 6–10 weeks, joinery 6–8 weeks. The longest line item sets your start date on site, so it pays to know which one that is before you commit.
Phase three · 2–4 weeks
Install and second-fix
Strip-out, first-fix plumbing and electrics, tiling, sanitaryware install, brassware fit, joinery, glass, lighting, snagging. The visible bit. Bespoke principal suites with stone walls and complex joinery can stretch to 5–6 weeks.
Phase four · 1–2 weeks
Snag and handover
Final snag list, silicone cure, glass screen install, commissioning, handover walk-through, aftercare brief. This usually overlaps with the end of phase three rather than sitting as a discrete block. A six-month aftercare visit follows for any settle-in issues.
One rule joins phases two and three: order before strip-out. Strip out before the product is on site and you own a half-demolished room sitting empty for six to twelve weeks, waiting on a brassware delivery from Germany. You also own an idle fitter on day rate, or the loss of your install slot entirely. Every designer-led showroom we know has a cautionary tale about a homeowner who stripped out their only bathroom on a Friday before the brassware arrived. Don’t be that homeowner.
There’s one exception. If you’ve got a usable spare bathroom in the house, some clients prefer to overlap phases two and three, starting strip-out and first-fix during the manufacture window. That shortens the overall clock by 2–3 weeks and raises the coordination risk in exchange.
03 · Design
Three to six weeks from first showroom appointment to signed-off specification, with a draft 3D render typically ready within 1–2 weeks of receiving your measurements. Total designer time across the period is 8–15 hours for a standard luxury bathroom. Bespoke principal suites with custom joinery push that to 18–25 hours.
The clock starts ticking at the first showroom appointment. That visit runs 60–90 minutes; the designer takes the brief, walks you through brand options at your spec level, and gives you a rough budget calibration. Measuring follows in week 2. We email you our step-by-step measuring guide, and you record the walls, ceiling heights, windows and reveals, doors and any sloping ceiling, then send the sizes back with photos of the soil pipe, the boiler or cylinder and the room as it is.
The CAD layout and 3D render get produced in weeks 3–4. It’s the longest single design output. This is where the room gets drawn at scale, every fitting placed against real joist runs and supply lines, every brassware code matched to real water pressure, every cistern measured against the recess it has to sit in. Clients enjoy the 3D render most, but the spec sheet is what prevents install-day failures: 60–120 line items for a standard luxury bathroom, every one a decision the designer has made on your behalf.
Two to three revision rounds is normal. Round one fixes the things you didn’t know you cared about until you saw them in 3D: the towel rail position, the basin centre line, the direction the shower glass opens. Round two fine-tunes the finishes, from brassware to tile colour to grout tone to silicone shade. Round three, if it happens at all, is price calibration: taking items out to hit budget, or upgrading where the budget stretches.
Sign-off is the moment the design phase ends and the order phase begins. It’s also the moment the spec sheet stops being editable without consequence, because every change after that carries a cost: revision time, restocking fees, or lost lead-time slots with manufacturers. We’ve documented the decisions that fill those 3–6 weeks in our designer’s 14-step planning checklist, which is a useful reference for what should be locked before you sign.
04 · Lead times
This is the section most timeline articles skip. Here are the real 2026 manufacture-and-delivery windows for the categories that drive luxury bathroom schedules, longest first.
2026 UK luxury bathroom lead times by category
| Category | Stock finish | Special finish or bespoke |
|---|---|---|
| Special-finish brassware (PVD, brushed nickel, matt) | 3–5 weeks | 8–14 weeks |
| Bespoke stone slabs (book-matched, large-format) | 2–3 weeks (in-stock porcelain) | 6–10 weeks |
| European sanitaryware (non-stock colourways) | 2–4 weeks (white, in stock) | 6–10 weeks |
| Bespoke vanity joinery | 3–4 weeks (off-the-shelf) | 6–8 weeks |
| Smart WCs (Geberit AquaClean, similar) | 3–5 weeks | 5–7 weeks |
| Freestanding baths (cast iron, stone resin) | 2–4 weeks | 4–6 weeks (painted bespoke) |
| Stock-finish brassware (chrome, white) | 2–4 weeks | — |
| Tile (porcelain, ceramic, in-stock ranges) | 1–3 weeks | 3–6 weeks (special order) |
Indicative 2026 UK lead times for designer-led showroom orders. Verify current windows with the supplier at the point of order.
Three categories cause most of the slippage we see. Special-finish brassware is the biggest single risk: Hansgrohe Axor in PVD bronze or brushed nickel, Crosswater Union in matt black, JTP Vos in PVD finishes. Manufacturers quote 8–12 weeks and routinely run 12–14, and during peak European holiday windows (mid-July through August, December) some lines pause production entirely. So order long-lead brassware on day one of sign-off.
Bespoke stone slabs from suppliers like Ca’ Pietra are the second risk. Book-matched pairs (two slabs mirroring each other across a feature wall) take 6–10 weeks from order, because the supplier holds back two slabs cut from the same block, works them to your dimensions and ships them as a coordinated pair. A single slab from a stocked range can be 2–3 weeks. Specify book-matching or large-format and the clock multiplies.
European sanitaryware in non-stock colourways is the third. Catalano and similar Italian houses keep their core ranges in stock in white; ask for a colour (cement, sage, terracotta) or a non-stock model and the order joins a factory queue that runs 6–10 weeks. The white version of the same model from the same factory might ship in two.
A scheme like this looks like a 4-week install on the surface. The reality is a 16-week clock: 5 weeks design, 9 weeks manufacture, 4 weeks site.
05 · The site phase
The install phase is the visible bit. Two to four weeks for a standard luxury bathroom, five to six for a bespoke principal suite with stone walls and complex joinery. Here’s what happens, week-by-week, on a typical 4-week schedule.
Existing bathroom stripped. Old waste pipes capped. First-fix plumbing run for new layout (hot/cold supplies, waste runs, valve boxes for concealed cisterns). First-fix electrics installed, with all bathroom circuits 30mA RCD protected per BS 7671:2018+A4:2026. Floor screed or tanking laid where the layout has changed. Walls patched and prepped for tile.
Wall tile installed first, floor tile second. Tile cuts around brassware penetrations come off the spec sheet rather than getting improvised on the day. Second-fix plumbing follows: shower valves connected, basin and bath waste fittings installed, isolation valves set. Second-fix electrics commission the lighting circuits, extract fan (15 L/s intermittent or 8 L/s continuous per Approved Document F), shaver socket and mirror demist if specified.
WC, basin, bath installed. Brassware fitted to designed pressure: thermostatic mixers commissioned, monobloc taps tested for blend balance. Bespoke vanity joinery installed and aligned. Mirrors, light fittings, towel rails and accessories all hung, then a snagging walk at the end of the week.
Glass shower screen or bath screen installed, always last, which prevents tile damage during the install. Silicone applied, with a 24–48 hour cure. Final snag list completed and the commissioning walk-through happens with you there. Aftercare brief covers cleaning of natural stone, brassware finish care and smart-WC settings if installed. Building Control signs off any notifiable work under Part P.
That’s a clean 4-week install. Week 1 is the riskiest moment, because it’s where joist failures, soil-pipe surprises and hidden lath-and-plaster turn up. Accurate measurements and photos in week 2 of the design phase flag the likely ones early. Never assume, though. We always quote a 5-day buffer for week 1 on period properties.
Notifiable electrical work under Approved Document P needs a Part-P registered competent person installing it, or notification through Building Control before work starts. Most luxury showroom installers use the competent-person route because it’s quicker, and it gets the homeowner a Building Regulations Compliance Certificate within 30 days of completion. Going direct through Building Control adds 2–6 weeks, purely for inspection scheduling.
If you’re using your own fitter rather than a showroom-vetted installer, the install phase tends to stretch by 1–2 weeks. That isn’t because the fitter is slower. It’s because spec questions get routed back to the showroom for clarification instead of answered on site. An integrated designer-installer-products model, one team accountable end-to-end, compresses the schedule because nobody has to ask anyone else what was meant.

06 · The drag
In rough order of frequency, three things account for most timeline slippage on luxury bathrooms in 2026. Two of them are fully avoidable. The third is a known risk you can plan around.
Cause one · most common
Late client decisions during design
Every revision round after the second adds 5–10 days to the design phase, and every change after sign-off adds days or weeks depending on what’s already on order. Change your tile choice three weeks after sign-off and you can lose 6–8 weeks, if the new tile sits on a longer lead time than the original. Design is the cheap phase to iterate in. Once orders are placed, every change carries a manufacturing or restocking cost. Decide everything before you sign.
Cause two · the constant
Special-finish brassware lead times
PVD bronze, brushed nickel, matt black, gunmetal: all of them routinely run 12+ weeks even when manufacturers quote 8. European factory holiday closures (mid-July through August, December) can pause production entirely. There’s no way round this beyond specifying stock-finish chrome, white or polished brass, which most luxury clients don’t want to do. So the work-around is to order on day one of sign-off and accept that the brassware lead time sets your install date.
Cause three · the surprise
Site-discovered problems on strip-out
Rotten joists under the freestanding bath. A soil pipe sitting two inches off where the drawings said it was, or lath-and-plaster behind a wall everyone had taken for plasterboard. A 1930s steel girder in the wrong place. These turn up in week 1 on roughly one in three period-property bathrooms we work on, and they add 3–10 days. Good photos, accurate measurements and your fitter’s pre-start check flag some of them; the rest are unknowable until the wall comes off. We always carry a 5-day buffer on Victorian, Edwardian and pre-1940 properties.
07 · The role
A designer’s job on the timeline isn’t to make it shorter. It’s to make it predictable. A properly designed luxury bathroom runs roughly the same length whether you use a designer or not; what changes is the variance. Without one, the average job still lands within a few weeks of plan. The worst case runs months over. With one, the worst case is also a few weeks over, because the variance got engineered out at the spec sheet.
The designer manages three things on the schedule specifically. One: long-lead items get ordered first. The day after sign-off, the brassware order goes in ahead of tile and sanitaryware, because the designer knows which line item sets the clock. That clock starts immediately. Two: the design stage flags joist and soil-pipe questions before they’re install-week emergencies. Accurate measurements and photos in week 2 of design, plus a pre-start check by your fitter, are the cheapest insurance you can buy against a 5-day install delay. Three: revisions are gate-controlled. A good designer pushes back beyond two or three rounds, on the basis that more rounds usually mean an unresolved brief, and an unresolved brief is what produces the expensive post-sign-off changes.
The integrated designer-installer-products model adds a fourth: spec questions during install get answered same-day, by the person who wrote the spec sheet. Without integration, the fitter calls the showroom to ask whether the towel rail valve is meant to be on the left or right; the showroom calls the designer; the designer calls the fitter back. Two days lost on a clean question. With integration, the fitter texts the designer a photo and gets a one-line answer in 30 minutes.
If you’re still deciding whether you need a designer at all, we’ve covered that question in our honest guide to whether a bathroom designer is worth it. It runs through the four trigger conditions, the cost-versus-value maths, and when a fitter on their own is the right call.
Three projects, three timeline shapes
“A designer doesn’t make the schedule shorter. They make it predictable.”
08 · The plan
Most homeowners come to us with a finish date in mind and work backwards. The maths is simple enough. What catches people out is bracket creep, so here are the working-backwards numbers for the three most common finish targets.
Working backwards from common finish dates · 2026
| Finish target | Standard luxury (16–18 wk) | Bespoke principal (24–28 wk) |
|---|---|---|
| Christmas (mid-Dec finish) | First appointment by mid-July | First appointment by mid-May |
| Summer holiday (end July finish) | First appointment by mid-March | First appointment by mid-January |
| Easter (early April finish) | First appointment by early December (year prior) | First appointment by mid-October (year prior) |
Add 2–3 weeks of contingency to all dates if your spec includes special-finish brassware or bespoke stone slabs.
Here’s the classic mistake. A homeowner books the first appointment in September thinking “two months is plenty for Christmas”. In the standard luxury bracket, two months is half a design phase, so you’ll be lucky to reach sign-off by Christmas, let alone install. The clients who reliably finish on time book six months out and accept that design and order run quietly in the background while life carries on.
Two more realities to factor in. Manufacturer holiday closures: most European factories close for two to three weeks across August (Italy and Germany), and one to two weeks across Christmas and New Year. An order placed mid-July sits in the queue until early September, and one placed mid-December sits until mid-January. Plan around that or accept the slip. UK Easter and bank-holiday weeks: install schedules around Easter and the May bank holidays often lose one to two days each, and your fitter may want to work around their own holidays too. Build in a week of buffer if your install crosses one of these.
Cost drives lead time directly, so if you want a sense of what sits behind each tier, our luxury bathroom cost guide walks through £15k, £25k and £40k+ specs line-by-line.
Everything UK homeowners ask about luxury bathroom renovation timelines.
What is next
A luxury bathroom finishes on time when four things went right beforehand. The design phase ran without crisis. The long-lead items were ordered the day after sign-off, the design stage flagged the joist question before it became a week-1 problem, and the fitter had every spec answered before they set foot in the room. None of that happens on a 4-week clock. It happens on a 16-week clock that someone planned properly, which is why six months out is the right time to start rather than three.
We run our design service at the Braintree and Leigh-on-Sea showrooms, and the install side runs through a vetted installer network or alongside your own fitter (your call). There’s no separate design fee. We benchmark our product pricing against the major UK online retailers, so you don’t pay a premium for using a designer-led showroom either: the design comes alongside online prices rather than on top. If you want a real conversation about your finish date and the spec that gets you there, book in.
