Wet room vs walk-in shower: the honest comparison
A wet room costs £5,000 to £10,000 and suits accessibility, small rooms and the open spa look; a walk-in shower enclosure costs £1,200 to £3,000 and suits most family bathrooms. The decision turns on drainage route, who uses the room, and honest assessment of your floor.
What each one actually is
A walk-in shower is a low-profile tray (25mm to 40mm) with a glass screen: the water stays in one corner, the rest of the room is a normal bathroom. A wet room removes the tray entirely: the whole floor is re-formed to fall to a drain, the room is tanked wall-to-wall, and the shower area is open or behind a fixed screen. One is a fixture, the other is a construction method, which is why their prices are so far apart.
Cost, honestly
Walk-in shower, replacing a bath or old enclosure: £1,200 to £3,000 including tray, screen, valve and tiling of the wet area. Wet room conversion: £5,000 to £10,000, because you are buying a former deck or screeded fall, a full membrane tanking system, wall-to-wall tiling and often a new drainage route. The wet room's extra cost is not margin, it is materials and days.
Drainage decides more than taste
On Teesside's timber-floored terraces and semis, both options work: wet floors use pre-sloped former decks, trays sit on joists. The deciding factor is the waste route. A gravity run to the soil stack is cheap for either. Where levels do not allow gravity, a wet room needs a pumped waste (£400 to £800 extra and a maintenance point), while a raised tray sidesteps the pump entirely. The survey should establish the drainage route before anyone quotes.
Who should choose what
- Accessibility needs: wet room, without question. Level access, no tray lip, space for a seat and a carer. It is the single most common mobility job we quote, £3,500 to £6,000 for a straight bath-out conversion.
- Small second bathrooms: wet room wins. Removing the tray enclosure frees the whole room, and a 1.5m by 2m box becomes a usable shower room.
- The only family bathroom: think hard. Many buyers with young children want a bath, and an open wet room without one can narrow your resale market. A walk-in shower over a bath, or keeping one bath elsewhere in the house, hedges it.
- Rental properties: walk-in tray. Wet rooms in rentals suffer when tenants ignore seals and grout; a tray contains the risk.
The failure mode to avoid
Ninety percent of wet room horror stories are tanking failures: membrane skipped, corners not sealed, floor fall never water-tested before tiling. The fix is boring and absolute: the quote names the tanking system, the fall is tested with water, and only then do tiles go down. A wet room done properly is the most robust bathroom there is; done cheaply it is a leak with a five-year fuse.
