Which towns do we cover in Ayrshire?
Supplies across most of Ayrshire are soft. If that holds for your street in Kilmarnock, 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 Kilmarnock home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
What the job includes
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- Strip-out, waste removal, a final flow test to the drain and handover
- 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
- Slip-resistant porcelain floor tiles and wall tiling
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
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.
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.
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.
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 Scotland
A wet room inside an existing home does not need planning permission. In a flat, check your title deeds and any deed of conditions: agreement from the other owners or the factor 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 Scotland, a wet room that alters the drainage, involves structural work to the floor or forms a new bathroom may need a building warrant; a straight refit usually does not. Water fittings must meet the Scottish Water Byelaws 2014.
