Working in Cobham

In Cobham we cover KT11; we also cover Esher, 3.3 miles away, and Weybridge.

Cobham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In a compact Cobham bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet. If your Cobham bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.

Supplies across most of Surrey are hard. If your supply in Cobham 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

Floor strengthening or a ply overlay on timber floors so the surface does not flex
A thermostatic shower valve, exposed or concealed, with heads to suit your water system
Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
A frameless glass screen fixed to the wall and floor

Decisions to make first

Screen size

A screen of 1200 mm or more keeps spray off the rest of the room in most layouts. In a very small wet room, expect the whole floor to get wet.

Open or screened

A fully open shower with no glass only works in a larger room, with the basin, WC and towels well away from the spray.

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.

More about wet rooms

Wet rooms in Cobham: questions

How much should I budget for a wet room in Cobham?

A wet room in Cobham usually costs £6,700–£13,500 including VAT. Expect the lower end for a like-for-like job with standard products, and the upper end if things move or you choose premium finishes. Your quote is itemised and fixed in writing once agreed.

Who handles building control for a wet room in Cobham?

Building control for Cobham 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.

How long does a wet room take?

Allow 5–10 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Cobham.

Is the home survey in Cobham really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

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.
