Working in Castlereagh
We cover every part of Castlereagh, including BT5, BT6 and BT7, and nearby Belfast (2.3 miles) and Newtownabbey (6 miles).
In Castlereagh, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For a stone or cast-iron bath in a Castlereagh property, we check the floor structure before anything is ordered. We plan luxury bathrooms in Castlereagh with drawings and a full product schedule, and the price is fixed in writing once the design is agreed.
Most of County Antrim is supplied with soft water. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Floor strengthening where a stone-resin, cast-iron or natural stone bath needs it
- Concealed thermostatic or digital shower valves, set into the wall to the depth the manufacturer specifies
- A full snag check, sealing of stone where needed, and a handover of manuals and isolation points
- Underfloor heating, layered lighting and any steam unit wired by a qualified electrician, tested and certified
Decisions to make first
Freestanding bath material
Acrylic is light and warm to the touch. Stone resin holds heat and feels solid but is much heavier. Cast iron is the heaviest of all and nearly always needs a structural check.
Shower system
A concealed thermostatic valve with a ceiling head and handset is the usual choice. A digital valve sets the temperature from a wall panel, and a steam enclosure needs its own generator and supply.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers structural work, drainage and ventilation. There is no Part P, but the heating, lighting and shower circuits should be designed, tested and certified to BS 7671.
