Which towns do we cover in Dyfed?
Most of Dyfed is supplied with soft water. If that holds for your street in Llanelli, 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. In a compact Llanelli bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet.
What the job includes
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
- A frameless glass screen fixed to the wall and floor
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- Slip-resistant porcelain floor tiles and wall tiling
- 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
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.
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.
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 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.
