Working in Derry

As well as Derry itself (BT47 and BT48), we survey in Limavady, Coleraine and Magherafelt.

In a city the size of Derry, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Derry home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain. If your Derry bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.

Most of County Londonderry is supplied with soft water. If that holds for your street in Derry, 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.

What the job includes

A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
Strip-out, waste removal, a final flow test to the drain and handover
A pre-formed floor former with a linear or centre drain, or a screed laid to fall
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.

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 Northern Ireland

In Northern Ireland, building control covers new drainage, ventilation and structural changes to the floor. There is no Part P, but the electrics should be tested and certified to BS 7671.

More about wet rooms

Wet rooms in Derry: questions

How much should I budget for a wet room in Derry?

A wet room in Derry usually costs £5,300–£10,500 including VAT. Expect the lower end for a like-for-like job with standard products, and the upper end if things move or you choose premium finishes. Your quote is itemised and fixed in writing once agreed.

Do you cover BT47 and BT48 in Derry?

Yes. We cover all of Derry, including BT47 and BT48, and nearby Limavady, Coleraine and Magherafelt. Survey visits are free and arranged at a time that suits you.

Is the water hard in Derry?

Does a wet room in Derry need building control approval?

Building control in Derry is run by the local district council. Where approval is needed, for example for new drainage, we tell you at the survey and handle it as part of the job.

What is tanking in a wet room?

Tanking is the waterproof layer under the tiles that stops water reaching the floor and walls. It is usually a liquid or sheet membrane, with sealing tape at every corner, board joint and pipe. Tiles and grout are not waterproof on their own, so the tanking is what actually keeps the water in.
