Working in Castlereagh
In Castlereagh we cover BT5, BT6 and BT7; we also cover Belfast, 2.3 miles away, and Newtownabbey.
In Castlereagh, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We quote wet rooms in Castlereagh only after looking at the floor construction, because that is where most of the cost difference lies. If you are planning a wet room in Castlereagh for level access, we design the fall and drain so the floor is flush from the doorway.
Supplies across most of County Antrim are soft. If that holds for your street in Castlereagh, 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 pre-formed floor former with a linear or centre drain, or a screed laid to fall
- Strip-out, waste removal, a final flow test to the drain and handover
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
Decisions to make first
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.
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.
