Working in Castlereagh
We work right across Castlereagh — BT5, BT6 and BT7 — and in neighbouring Belfast and Newtownabbey.
In Castlereagh, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you are refreshing a dated cloakroom in Castlereagh, a wall-hung WC and slim vanity can change the room in a few days. For a new cloakroom in Castlereagh, the first thing we look at is where the nearest drain or soil stack runs.
Supplies across most of County Antrim are soft. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- A concealed cistern frame or WC unit where the space allows
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
Decisions to make first
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers new drainage and ventilation, with ventilation set out in Technical Booklet K. The Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 limit a new WC to a 6-litre flush.
