How much does a wet room cost in the UK?
A Bowmans wet room starts at around £8,000 for products alone, and most land between £8,000 and £16,000, including sanitaryware, brassware, the wet-room former, tiles and furniture, before installation. Some guides quote £4,000 to £14,000 or more for the whole job, which sounds lower until you notice they’ve bundled products and labour into one number. Installation is priced separately by your fitter. Get every quote split into products, the floor build-up and labour before comparing it with another. The Bowmans product figures on this page are retail prices including VAT.
You can open four wet-room cost guides and find four different answers. One gives you a figure below £5,000, another starts at £6,000 and runs past £14,000 for a bespoke room, and none of it helps if you can’t see what each number actually buys.
The figures disagree because some publishers combine products and labour while others don’t. The specification is often left unstated, so you can’t tell whether the price covers basic sanitaryware or bookmatched stone and two ceiling-mounted showers. Undated pages make matters worse because there’s no way to know when the prices were checked.
Bowman Bathrooms designs and supplies wet rooms but doesn’t install them. That means we have to separate the figures into products, the wet-room floor build-up and installation labour. It’s also the most useful way to read any quotation, because it shows where the money is going and whether two prices are genuinely comparable.

Why does every wet-room cost guide give you a different number?
The published figures disagree because they aren’t measuring the same thing.
MyJobQuote, published on 2 July 2026, gives fitted costs of £4,675 for a small wet room, £5,885 for a standard room and £8,360 for a large one. EA Mobility, updated on 14 April 2026, places a standard wet room at £6,000 to £8,000, a mid-range room at £8,000 to £10,000, luxury at £11,000 or more and bespoke at £14,000 or more.
Bathroom Mountain’s undated guide, pricing a conversion from an existing bathroom, gives £4,000 to £5,500 for a basic room, £5,500 to £8,000 for mid-range and £8,000 to £12,000 or more for high-spec work. Victorian Plumbing, writing on 20 May 2024, gives a broader £4,000 to £10,000 figure.
Those numbers look precise, but three problems make them difficult to compare. First, labour and products are bundled together, which hides how much of the budget has gone into the specification, and the guides rarely tell you which basin, shower, drainage system, furniture or tiles the figure buys. A £7,000 room with basic products is a different proposition from one using the same budget for products alone.
And one of those four carries no date at all, as plenty of others don’t. Product and trade prices change, so a figure without a publication date has limited value.
Whether the headline figure includes VAT is not stated in any of the four guides, and EA Mobility shows its worked example before VAT is added. Check the VAT treatment on any of them before setting it against a figure here.
The better approach is to split every quotation into products, the specialist floor construction and installation labour. If you’re pricing the entire bathroom rather than the wet-room element, our full bathroom cost guide explains where the wider budget goes.
How a wet-room price breaks down
A useful wet-room price has three parts: the products you select, the construction that creates the waterproof floor and the labour required to complete the room.
Bowmans quotes the products because design and supply is our core service. Installation comes from your own fitter or someone from our Approved Fitter Network after they’ve inspected the room. Keeping those figures separate makes it much easier to change the specification without losing sight of the effect on the total budget.
Products
This covers the sanitaryware, brassware, wet-room former and drainage kit, tiles and furniture. Bowmans designs the room and supplies these products. The amount changes with the products and finishes you choose, so the quotation should identify them rather than hiding them inside a single allowance.
The floor build-up
This is the part that makes the room a wet room. It includes creating the falls towards the drain, tanking the floor and relevant walls, and bedding and sealing the drainage components. The existing floor construction affects how straightforward that work will be.
Installation labour
Your fitter quotes separately for strip-out, plumbing, electrics, tiling and fitting after a site survey, because access, drainage changes and the structure beneath the existing floor all affect that quotation. A published day rate can provide context, but it can’t price the completed job.
This split also prevents a common problem during specification. If you decide to spend more on tiles or furniture, you can see exactly what has changed. The waterproofing and labour don’t disappear inside a revised package price.
The same principle applies when you’re comparing suppliers. Ask each one to identify the product specification and confirm whether tiles, waterproofing materials and fitting are included. Without that detail, the lowest total tells you very little.
What a wet room costs by spec in 2026
For a wet room of about 5 square metres, the Bowmans Price Guide uses four product tiers. The base figures below are supply only and exclude tiling and installation. Tiles are shown separately as a supply price per square metre.
| Spec tier | Product base, supply only, about 5 sq m | Tile supply, extra, per sq m |
|---|---|---|
| Standard | £6,000 | £40 |
| Premium | £7,500 | £50 |
| Luxury | £10,000 | £80 |
| Super-Lux | £18,000 | £110 |
The £6,000 Standard figure is the smallest-format Standard-tier wet-room specification. It covers the product base, while tiling and installation remain separate. At the other end, the Super-Lux tier allows for a much stronger specification across the sanitaryware, brassware, furniture and accessories.
On paper the tiers start at £6,000. In practice, the wet rooms we design come in at around £8,000 and up, and most land between £8,000 and £16,000. The Super-Lux tier sits above that band, at £18,000 for the product base.
A wet room can be built for less than our starting point, and the guides above prove people do it every week. We've chosen not to work at that end of the market. Below a certain specification the savings have to come out of the tanking, the drainage and the glass, and those are the parts doing the quiet, permanent work under the tiles. Our floor sits where the specification stops being negotiable.
The base price excludes tiling. That matters because the tile rate changes from £40 per square metre at Standard level to £110 per square metre at Super-Lux level. The amount of tiled wall and floor area can therefore change the product total even when the room itself has the same footprint.
Underfloor heating is calculated separately and doesn’t scale with the four specification tiers. The mat is priced on the heated area rather than the whole floor, because fixtures take their slice: the first square metre costs £100, each further square metre £44, and the smart thermostat adds £200. These are product prices, with fitting quoted separately by your fitter.
“This estimate covers the complete supply of products for your project — fixtures, fittings, tiles and brassware. Installation is quoted separately following a site survey.”
That estimator wording refers to the completed estimate after the separate tile selections have been added. The base-price column in the table above still excludes tiling, which is why the tile supply rate has its own column.
Check the exclusions. A £6,000 supply-only quotation with no tile line cannot be compared directly with an £8,500 product quotation that includes tiles. Ask what has been left out before deciding which total represents better value.
If you want to test different product levels, use our interactive product price guide. You pick the room type, finish level, dimensions, tiling and any extras, then leave your details and the estimate comes through. It’s a starting point for the products, before a designer prices the actual room.
What seven real Bowmans wet rooms cost in Essex
Completed rooms give the product bands some context. Every figure below covers products only, with installation quoted separately by the fitter. The project pages do not publish a floor area, so we haven’t estimated one.
| Project | Products | Duration | What is in it |
|---|---|---|---|
| Highwoods, Colchester CO4 ensuite wetroom | £8,000–£10,000 | 3 weeks | Ca’ Pietra Ocean Magnifique bookmatched tiles, Porcelanosa Boulder floor, Roper Rhodes vanity, HiB Bellus mirror, Warmup underfloor heating and a flush linear drain |
| Braintree CM7 luxury ensuite wetroom | £10,000–£12,000 | 3 weeks | Ca’ Pietra Ocean Magnifique and Dorset Beige, JTP chrome rainfall shower, Calypso Loreto vanity, IP67 lit niche, On The Level former and Lakes Showering glass |
| Great Bardfield CM6 family wetroom | £11,000–£13,000 | 4 weeks | BC Designs Elmstead bath, full Impey wet-room floor running beneath the glass screen, Ca’ Pietra Provence, Roper Rhodes, Warmup and HiB |
| Chelmsford CM2 family bathroom | £12,000–£15,000 | 3 weeks | On The Level wet-room floor tiled flush, slim linear channel, Calypso walnut vanity, JTP brassware and Warmup underfloor heating |
| Copford Green CO6 master ensuite | £13,000–£15,000 | 3 weeks | Elisa Intuition smart shower, Porcelanosa pebble tiles, Crosswater products and Calypso Dartmoor furniture |
| Halstead CO9 master ensuite wetroom | £19,000–£21,000 | 4 weeks | Ca’ Pietra Nero Magnifique bookmatched tiles, full tanking, linear waste drain, half-height glass, Calypso oak furniture and IP67 LED lighting |
| West Mersea CO5 spa-style master ensuite | £25,000–£30,000 | 5 weeks | Bookmatched Ca’ Pietra Magnifique Nero, two ceiling rain showers, Porcelanosa Boulder pebble bench with underfloor heating in the seat, BC Designs Crea bath, JTP Evo brushed bronze, Ambiance Bain vanity and Geberit WC |
The spread in those figures is being driven much more by specification than by the name given to the room. Highwoods and West Mersea are both ensuite wet rooms, yet their product costs sit in very different bands.
The difference isn’t stated floor area because neither project publishes that measurement. It’s the specification. West Mersea includes bookmatched stone, two ceiling-mounted rain showers, a heated pebble bench, a freestanding bath and a broader mix of furniture and brassware. Highwoods uses a more contained product selection and came in between £8,000 and £10,000 for products.
That’s why room labels such as “small”, “family” or “ensuite” can only take you so far. Once the basic drainage and waterproofing products are accounted for, the bath, shower, furniture, tile and brassware choices determine where the room sits within the range.
What is in the wet-room floor build-up
A wet-room floor needs a former, tanking and a drain that work together. A normal bathroom can contain water within a bath or shower tray. In a wet room, the tiled floor itself has to direct shower water towards the waste while protecting the structure underneath.
The former creates the shaped area around the shower and gives the tiles a controlled route towards the drain. It may need to sit within or above the existing floor, depending on the system and the structure of the room. On a refurbishment, that affects thresholds, door clearance and the finished level outside the bathroom. If you’re still deciding between a tileable former and a conventional shower tray, our wet room former vs shower tray guide sets out the practical difference.
Tanking creates the waterproof layer behind the visible finish. Tiles and grout form the surface you see, but the waterproofing sits beneath them. Our guide to bathroom tanking explains where it goes and how the different systems are used.
For materials only, our own UK retail price check from August 2026 puts a full wet room using a membrane, former and gully across 15 to 25 square metres at about £800 to £2,500, including VAT.
The drain receives the water from the formed floor and connects it to the waste pipe. Its position can affect the former, tile setting-out and the depth needed below floor level, which is why choosing it late can cause unnecessary changes.
There’s no Building Regulation that sets a fixed wet-room floor gradient. The required fall comes from the installation instructions supplied by the former or drain manufacturer. We’d want the chosen system confirmed before the floor is prepared so the installer is working to the right detail.
Based on Bowmans 2026 supplier pricing, choosing a wet room over a standard walk-in shower in a 5 to 6 square metre room adds £1,500 to £3,500 across the job, including VAT on the product elements. Your fitter’s own VAT position depends on whether they are VAT-registered. That premium covers the former, the tanking and the drainage as well as the extra tiling labour around the fall, set against the shower tray you no longer buy. It’s the gap between two ways of building the room, not a separate line to add on top of the product figures above. The wet room vs walk-in shower cost breakdown shows where that additional work comes from without folding it into the supply price.
What wet-room labour costs
Bowmans doesn’t quote wet-room labour. The figures here are third-party published rates, rather than a Bowmans quotation, and they show why a site survey still matters.
Bathroom Mountain puts specialist wet-room installers at £200 to £300 a day. Victorian Plumbing, dated 20 May 2024, gives £200 to £300 per person per day and reckons a wet room usually needs two people on site. Those are their published figures, not ours, and neither states its VAT position, so check what each one covers.
The range is wide because a day rate describes someone’s time rather than the work your particular room requires. A straightforward room with easy access and drainage remaining in the same area is a different job from one where the waste needs to move and the existing floor has to be altered.
Floor construction matters as well. A joisted floor and a concrete slab present different questions for drainage, levels and preparation. The fitter also needs to assess access into the property, strip-out, plumbing alterations, electrical work, tiling and the amount of making good required around the room.
So we’d use a published day rate as a sense check, then rely on a written quotation based on the actual design and a site visit. Ask the fitter to state what’s included, particularly preparation, electrics, decorating and waste removal. A shorter quotation can look cheaper simply because several parts of the job will be charged later.
How installation works at Bowmans
Your fitter or ours. You can use your own trusted tradesperson, or Bowmans can introduce you to an installer from the Approved Fitter Network. Its members are independently vetted, DBS-checked and carry at least £5 million in public liability insurance.
Installation is always quoted separately by the fitter after a site survey. Bowmans remains responsible for the design and product supply.
What moves your number up or down
The room’s footprint matters, but it’s only one part of the price. These are the areas we’d look at before putting a product specification together.
- Room size. A larger floor usually needs more tile, heating coverage and waterproofing materials. Small rooms don’t shrink proportionally in cost because they still need a former, drainage connection and waterproofing set-up.
- Tile or stone choice. The product table allows £40 per square metre at Standard level and £110 per square metre at Super-Lux level, but the total also depends on how much of the wall you decide to tile. Bookmatched surfaces can move a room further because their placement needs to be planned around the visible features.
- Drainage type. A linear channel and a point gully create different visual details and can affect how the tiles are set out. We’d choose the drainage with the floor system and structure in mind rather than selecting it as an isolated finish.
- Underfloor heating. Heating adds the mat or cable, controls and installation work, so it should be decided early because it sits within the floor build-up. Our guide to bathroom underfloor heating explains the choice between wet and electric systems.
- Bespoke or standard furniture. Standard furniture can work very well when the available widths suit the room. Bespoke pieces make sense where they solve an awkward dimension or deliver a finish unavailable in the standard ranges, but they move the specification upwards.
- Structural access. A joisted floor creates different options from a concrete slab. The available depth also matters because the former, drain and finished tiles have to meet the surrounding floor without leaving an unwanted threshold. That needs checking on site before anyone commits to a construction method.
Verdict
If your specification sits around the middle of the table and the room is a standard 5 to 6 square metres, budget within the Premium to Luxury product band. That means £7,500 to £10,000 supply only, excluding tiling and installation. Then ask a fitter to quote separately for the floor build-up and the rest of the installation after a site survey.
What an accessible wet room costs
An accessible wet room uses the same product bands, but the layout needs to prioritise level access. There should be no step or threshold into the shower area, and the room may need additional turning space to suit the person using it.
The relevant VAT treatment depends on the individual and the work. HMRC VAT Notice 701/7 says that providing, extending or adapting a bathroom can be zero-rated where the work is necessary to suit the condition of a disabled person and the building is their private residence. Paragraph 6.3.2 confirms that a bathroom includes a shower or wet room. The supplier should obtain a written declaration from the customer under paragraph 3.6.
That doesn’t mean every accessible wet room qualifies. Check the conditions in HMRC VAT Notice 701/7 before relying on zero-rating in a budget.
In England, the Disabled Facilities Grant can provide up to £30,000 and is means-tested using household income and savings over £6,000. Where the disabled person is a child under 18, the parents’ income isn’t counted. The council must approve the work, and beginning before approval can mean the grant is lost. Read the current Disabled Facilities Grant guidance before starting an application.
Check your own position before budgeting. These grant figures and VAT conditions are correct at publication on 31 August 2026. Eligibility is assessed against your circumstances, so confirm the current rules with your local authority and on gov.uk before relying on either relief.
