Which towns do we cover in West Glamorgan?
Most of West Glamorgan is supplied with soft water. If that holds for your street in Swansea, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier. If your Swansea bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.
What the job includes
- Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
- 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
- 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
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
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.
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.
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.
Rules that apply in Wales
A wet room inside an existing home does not need planning permission. In a flat, check the lease: freeholder consent is often needed, and both the leak risk and the sound insulation to the flat below matter. Electrics must meet BS 7671, with 30 mA RCD protection, at least IPX4 fittings in zone 1 up to 2.25 m above the shower floor, IPX5 where water jets are used, and no ordinary sockets within 3 m of zone 1.
In Wales, Part H covers new drainage and the Welsh Part F sets similar extract rates. The Welsh Part P makes more electrical work notifiable than in England, so the electrician should notify and certify the work.
