Working in Sunbury-on-Thames
We work right across Sunbury-on-Thames — KT12, TW16 and TW17 — and in neighbouring Walton-on-Thames and West Molesey.
Homes in and around Sunbury-on-Thames vary, so we look at the floor, the walls and the water system before we price anything. If your Sunbury-on-Thames bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor. If your Sunbury-on-Thames home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
Most of Surrey has hard water. If your supply in Sunbury-on-Thames 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 pre-formed floor former with a linear or centre drain, or a screed laid to fall
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- A frameless glass screen fixed to the wall and floor
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
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.
