Working in Merthyr Tydfil
We work right across Merthyr Tydfil — CF47 and CF48 — and in neighbouring Aberdare and Rhondda.
Homes in and around Merthyr Tydfil vary, so we look at the floor, the walls and the water system before we price anything. If you are refreshing a dated cloakroom in Merthyr Tydfil, a wall-hung WC and slim vanity can change the room in a few days. We survey cloakrooms in Merthyr Tydfil with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Most of Mid Glamorgan is supplied with soft water. 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
- Lighting wired by a qualified electrician, tested and certified
- Splashback or feature tiling and a new floor, often LVT or porcelain
- 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
Decisions to make first
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.
WC style
A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.
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.
