Bath-to-Shower Conversion Costs UK — What to Charge to Replace a Bath with a Shower in 2026
Replacing a bath with a walk-in shower is one of the most requested bathroom jobs in the UK. Plenty of households never use the bath, want more space, or need step-free access as they get older. For a bathroom fitter or plumber it's a reliable, repeatable earner — but only if you price it properly. The gap between a quick enclosure swap and a fully tanked wet-room is enormous, and operators who quote a single "average" figure regularly lose money on the harder jobs. This guide gives you the real 2026 numbers: typical ranges, what drives the price, a worked example, and how to avoid the classic underpricing traps.
Typical Bath-to-Shower Conversion Price Ranges
There is no single price for a bath-to-shower conversion because the term covers everything from a half-day enclosure swap to a complete wet-room rebuild. Use these bands as your starting point and adjust for spec, access and region.
- Straightforward bath-to-shower swap (enclosure + tray): £1,500–£4,000
- Fully tiled walk-in / wet-room style conversion: £4,000–£7,000+
- Level-access / disability conversion: £6,000–£10,000+
The lower end is a like-for-like job: take the bath out, fit a tray and off-the-shelf enclosure where it stood, re-route the waste, fit a mixer or electric shower, make good, and tile a modest splashback. The upper bands involve forming a tiled wet area, tanking the room, levelling the floor, more extensive tiling, and often upgrading the water supply.
Labour, Removal and Materials Breakdown
Pricing accurately means separating three cost blocks before you build a quote: labour, removal and disposal, and materials. Knowing each one lets you flex the quote without guessing.
Labour
A typical conversion is a 3–5 day job, longer if a separate tiler is needed. Day rates in 2026 sit around £200–£300 per day for a fitter or plumber — higher in London and the South East — and a specialist tiler often commands the top of that range for intricate work.
- Simple enclosure swap: 2–3 days labour
- Tiled walk-in / wet-room: 4–6 days including tanking and tiling
- Plumber / fitter or tiler day rate: £200–£300/day
Removal and Disposal
Stripping out the old bath, panels and tiles generates a surprising amount of waste. Allow time to break out the bath plus a skip or waste-carrier run. A small skip is typically £150–£300, and bagging old tiles can add the better part of a day on a fully tiled bathroom.
Materials
Material cost swings widely with spec. A budget tray and enclosure can be had for a couple of hundred pounds; a low-profile stone-resin tray, frameless 8mm glass screen, quality thermostatic shower and porcelain tiling run to several times that. Indicative trade-buy figures:
- Shower tray (acrylic to stone-resin low-profile): £100–£400
- Enclosure or walk-in glass screen: £150–£700
- Mixer / thermostatic shower valve and head: £120–£500
- Tanking kit (wet-room): £80–£200 per room
- Wet-room former / former tray: £150–£400
- Tiles and adhesive / grout: £15–£60/m² depending on choice
- New extractor fan: £40–£150 plus wiring
What Drives the Price Up or Down
Two jobs that both "replace a bath with a shower" can differ by thousands. These are the factors that move your quote, and the ones to identify on your survey before you commit a figure.
Enclosure + Tray vs Tiled Wet-Room
This is the single biggest driver. A pre-formed tray with a glass enclosure is fast and predictable — you set the tray, seal it, and fit the screen. A tiled walk-in or wet-room means building in a sloped former, fully tanking the floor and lower walls, and tiling a large area to a waterproof, fall-to-drain finish. The wet-room route adds days of labour, a tanking system, a former and far more tiling — which is why it sits in the £4,000–£7,000+ band.
Shower Type: Electric vs Mixer vs Digital
An electric shower heats its own water and only needs a cold feed plus a dedicated electrical supply — useful where hot water pressure is poor, but it needs an electrician and the right cable and RCD protection. A mixer or thermostatic shower blends hot and cold for a better feel but relies on existing system pressure. A digital shower with a processor unit is the premium option and adds £300–£600+ to materials. Match the shower to the customer's system and budget, and price the electrical work in for electric units.
Water Supply, Pressure and Pumps
Shower performance lives or dies on supply. A combi boiler generally delivers good mains pressure straight to a mixer shower with no pump needed. A gravity-fed (tank and cylinder) system often gives weak flow upstairs, and a walk-in shower on gravity feed frequently needs a shower pump (£200–£500 plus fitting) or an unvented cylinder upgrade to feel acceptable. Always test pressure and flow on the survey — promising a powerful shower on a low-pressure gravity system without a pump is a complaint waiting to happen. Moving or upgrading the supply pipework should be a separate line in the quote.
Drainage, Waste and Floor Levels
A bath waste sits low and to one side; a shower tray or wet-room drain often needs the waste re-routed and re-graded to keep a fall. On a suspended timber floor you may need to notch joists (within permitted limits) or build up the floor; on a wet-room you set the drain and create the falls. Getting the levels right is one of the most underestimated parts of the job — allow for it properly.
Tiling Area and Making Good
Removing a bath leaves a wall and floor that were never meant to be on show — usually unsealed plaster, an unfinished floor and a tiling shortfall where the bath panel used to be. Making good and tiling that area is real work, and the larger the tiled area, the more the price climbs in both materials per m² and fitter or tiler days.
Extractor Fan (Building Regs Part F)
A shower puts far more moisture into the air than occasional bath use, so ventilation matters. Building Regulations Part F requires adequate extract ventilation in a bathroom, and many conversions are a good moment to fit or upgrade an extractor fan — typically £40–£150 for the unit plus electrical and ducting work. Quote it in rather than leaving the customer with a steamed-up, mould-prone room.
Wall Panels vs Tiles, and Glass Quality
Waterproof PVC or acrylic wall panels are faster to fit than tiles and avoid grout maintenance, which can shave labour — but premium panels aren't cheap. Tiles give more design choice and a higher-end finish but cost more in time. Glass screen quality also moves the price: a basic 6mm framed screen is far cheaper than a frameless 8–10mm walk-in panel. Spec these to the customer's budget and make the trade-offs clear in your quote.
Level-Access and Disabled Adaptations
A growing share of this work is driven by mobility needs — older or disabled customers who can no longer climb into a bath safely. These conversions sit at the top of the price range because they involve a level-access (step-free) shower, a wet-room or ultra-low tray, slip-resistant flooring, grab rails and often a fold-down seat. Forming a true level-access floor on a suspended structure means dropping or building up the floor and tanking thoroughly — more involved than a standard tray swap.
One important note: building or installing a shower as part of a disabled adaptation can be VAT zero-rated where the customer is chronically sick or disabled and the work qualifies under HMRC rules. It's not blanket — the customer usually self-certifies eligibility and the work must genuinely be an adaptation for their condition. Get the declaration in writing, keep it on file, and if you're unsure whether a job qualifies, check current HMRC guidance or your accountant before quoting net of VAT.
Quick Reference: Bath-to-Shower Conversion Prices UK 2026
| Conversion type | Typical price | Labour |
|---|---|---|
| Enclosure + tray swap (basic) | £1,500–£2,500 | 2–3 days |
| Mid-range swap (better tray, screen, tiling) | £2,500–£4,000 | 3–4 days |
| Tiled walk-in / wet-room conversion | £4,000–£7,000+ | 4–6 days |
| Level-access / disabled adaptation | £6,000–£10,000+ | 5–7 days |
| Add: shower pump (gravity systems) | £200–£500 + fitting | |
| Add: new extractor fan (Part F) | £40–£150 + wiring | |
| Add: skip / waste disposal | £150–£300 | |
Worked Example: A Mid-Range Conversion
A customer with a combi boiler wants their unused first-floor bath replaced with a walk-in shower: a low-profile stone-resin tray, an 8mm frameless screen, a thermostatic mixer shower, half-height tiling to the wet wall plus a splashback, and a new extractor fan. Supply pressure tests fine on the combi, so no pump is needed. Here's how the quote builds up:
- Labour: 4 days @ £250/day = £1,000
- Removal, disposal and small skip: £250
- Tray, screen and thermostatic shower: £700
- Tiles, adhesive and grout (approx 8m²): £280
- Waste re-route, fittings and sundries: £200
- Extractor fan and electrical work: £170
- Make-good and plastering materials: £100
That's roughly £2,700 in cost and labour. Add overhead and margin — say 25–30% — and you land around £3,400–£3,500 for the customer, comfortably in the mid-range band. On a gravity system needing a pump, or with full-height porcelain tiling throughout, the price climbs toward the £4,000+ mark and tips into wet-room territory.
Quoting Tips and Avoiding Underpricing
Most losses on bath-to-shower jobs come from quoting before a proper survey and from treating a tiled wet-room like a tray swap. Protect your margin with these habits:
- Never underprice the tanking. A wet-room lives on its waterproofing. Skimping on tanking days or materials is how you end up returning to a leak you can't bill for. Price the full system and the time to apply it correctly.
- Test pressure and flow on the survey. Identify combi vs gravity and price a pump or supply upgrade in if the system needs it. Don't promise performance you can't deliver.
- Allow for the unknowns behind the bath. Rotten boarding, poor pipework and unfinished plaster are common once the bath is out. Build a contingency or note that hidden defects are extra.
- Separate your line items. Show labour, removal, materials, electrical and any pump work as distinct lines so you aren't undercut by operators who skip access, ventilation or waterproofing.
- Price the extractor and Part F ventilation in. A showered room without proper extract will steam, mould and generate callbacks.
- Get the disabled-adaptation paperwork right. If you're zero-rating VAT, keep the signed eligibility declaration on file. Don't apply zero-rating on a guess.
- Measure the tiled area properly. Tiling is where estimates drift — measure the m² and price both the time and the tiles rather than eyeballing it.
A clear, itemised quote with a brief survey note — system type, pressure reading, tanking spec, tile area and any defects found — sets you apart from competitors who send a single number, and justifies a price that protects your margin.
