Working in Lisburn
We work right across Lisburn — BT17, BT26, BT27 and 1 more postcode districts — and in neighbouring Belfast and Castlereagh.
In a city the size of Lisburn, parking and access for a skip are worth sorting before the start date — we will ask at the survey. In a compact Lisburn bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet. If your Lisburn bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.
Water across much of County Antrim is soft. If that holds for your street in Lisburn, 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
- 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
- Slip-resistant porcelain floor tiles and wall tiling
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
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.
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.
