What does a wet room cost in Southampton?

Working in Southampton

As well as Southampton itself (SO14, SO15, SO16 and 3 more postcode districts), we survey in Hythe, Totton and Hedge End.

In a city the size of Southampton, parking and access for a skip are worth sorting before the start date — we will ask at the survey. We quote wet rooms in Southampton only after looking at the floor construction, because that is where most of the cost difference lies. If your Southampton bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.

Water across much of Hampshire is hard. If your supply in Southampton is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
A pre-formed floor former with a linear or centre drain, or a screed laid to fall

Decisions to make first

Underfloor heating

Electric underfloor heating under the tiles dries the floor quickly after a shower; it is typically £700 to £1,500 for a bathroom.

Floor tile

Matt or textured porcelain with good slip resistance. Mosaic gives extra grip on a centre-drain floor because of its many grout lines.

Rules that apply in England

In England, a new drain connection or changes at the soil stack can be building-regulations work under Part H, and new circuits or changes to the wiring in the room are notifiable under Part P. If the wet room is a newly formed bathroom, Approved Document F requires extract of 15 litres per second intermittent or 8 litres per second continuous.

Who handles building control for a wet room in Southampton?

Building control for Southampton is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

What is tanking in a wet room?

Tanking is the waterproof layer under the tiles that stops water reaching the floor and walls. It is usually a liquid or sheet membrane, with sealing tape at every corner, board joint and pipe. Tiles and grout are not waterproof on their own, so the tanking is what actually keeps the water in.
