Working in Windsor

We cover every part of Windsor, including SL4, and nearby Slough (1.8 miles) and Egham (4.1 miles).

Homes in and around Windsor vary, so we look at the floor, the walls and the water system before we price anything. In a compact Windsor bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet. For a wet room in a Windsor flat, the first step is the lease, because freeholder consent is often needed before any work starts.

Supplies across most of Berkshire are hard. If your supply in Windsor 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

A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
A thermostatic shower valve, exposed or concealed, with heads to suit your water system
Floor strengthening or a ply overlay on timber floors so the surface does not flex

Decisions to make first

Linear or centre drain

A linear drain along one wall lets the floor fall in a single direction, so large tiles can be laid without awkward cuts. A centre drain needs a four-way fall and suits smaller tiles or mosaic.

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.

Wet rooms in Windsor: questions

How much does a wet room cost in Windsor?

A wet room in Windsor usually costs £6,700–£13,500 including VAT. The final figure comes down to what you choose and what we find at the survey; your written quote lists every item so you can see where the money goes.

Is the water hard in Windsor?

Who handles building control for a wet room in Windsor?

Building control for Windsor 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 Windsor.

Can you have a wet room on a wooden floor?

Yes. On a timber floor, the former usually sits down between the joists so the finished floor stays level, and the joists may need trimming, strengthening or extra noggins. The floor must be stiff, often with a ply overlay, so it does not flex and crack the tiles or the tanking. We check the joists at the survey before quoting.
