Working in Castlereagh
As well as Castlereagh itself (BT5, BT6 and BT7), we survey in Belfast, Newtownabbey and Lisburn.
In Castlereagh, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Castlereagh bathroom is a box room over the stairs, the first job is finding out where the soil stack lets the WC sit. If you live in a terrace or semi in Castlereagh with a compact bathroom, swapping a pedestal basin and close-coupled WC for wall-hung pieces is often the biggest single gain.
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
- A measured survey including the door swing, window position, soil stack and any boxing that could be slimmed down
- Strip-out, waste removal, testing and a clean handover
- Shorter, narrower or shower baths where a full 1700 mm bath does not sit well
- Lighting, extractor fan and towel rail wired by a qualified electrician, tested and certified
Decisions to make first
Door
Re-hanging the door to open outwards, or fitting a sliding door, frees the space behind it. In a very small room this alone can make space for a bigger shower.
Storage
Recess shelves into stud walls or boxing, put a mirror cabinet over the basin and use the wall above the WC. Avoid floor-standing units in very tight rooms.
Rules that apply in Northern Ireland
In Northern Ireland, building control is concerned with changes to drainage, structure and ventilation rather than a straight refit. There is no Part P, but the electrics should be tested and certified to BS 7671.
