Which towns do we cover in Northumberland?
Most of Northumberland is supplied with soft water. If that holds for your street in Blyth, 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 Blyth home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
What the job includes
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
- 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 thermostatic shower valve, exposed or concealed, with heads to suit your water system
- Slip-resistant porcelain floor tiles and wall tiling
- Strip-out, waste removal, a final flow test to the drain and handover
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.
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.
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.
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.
Rules that apply in England
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 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.
