Working in Gorseinon
As well as Gorseinon itself (SA4), we survey in Llanelli, Swansea and Clydach.
Gorseinon gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We survey cloakrooms in Gorseinon with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. If your Gorseinon cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Supplies across most of West Glamorgan 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
- A concealed cistern frame or WC unit where the space allows
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Strip-out of the old fittings, waste removal and making good on the hall side
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 Wales
In Wales, Part H covers a new drainage connection and the Welsh Part F covers ventilation, with rates similar to England. The Welsh Part P has a wider notifiable list, so check with your electrician whether the cloakroom lighting and fan need to be notified.
