Working in Coleraine
We cover every part of Coleraine, including BT51, BT52 and BT55, and nearby Limavady (12.6 miles) and Magherafelt (26.3 miles).
Homes in and around Coleraine vary, so we look at the floor, the walls and the water system before we price anything. If you are planning a wet room in Coleraine for level access, we design the fall and drain so the floor is flush from the doorway. We quote wet rooms in Coleraine only after looking at the floor construction, because that is where most of the cost difference lies.
Supplies across most of County Londonderry are soft. If that holds for your street in Coleraine, 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
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
- Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
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.
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.
