Working in Portsmouth
We work right across Portsmouth — PO1, PO2, PO3 and 3 more postcode districts — and in neighbouring Gosport and South Hayling.
Portsmouth is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. For a wet room in a Portsmouth flat, the first step is the lease, because freeholder consent is often needed before any work starts. If your Portsmouth home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
Water across much of Hampshire is hard. If your supply in Portsmouth 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
- A thermostatic shower valve, exposed or concealed, with heads to suit your water system
- Strip-out, waste removal, a final flow test to the drain and handover
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
Decisions to make first
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.
Former or screed
A pre-formed board gives a consistent fall and suits timber floors. A sand and cement screed suits concrete slabs and larger shower areas.
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.
