Working in Carmarthen
As well as Carmarthen itself (SA31), we survey in Llanelli, Ammanford and Gorseinon.
Being a smaller town does not change how we work in Carmarthen: free survey, written quote, one team. Where your Carmarthen home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. We survey cloakrooms in Carmarthen with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Water across much of Dyfed is 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 survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- 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
Decisions to make first
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.
Finishes
A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.
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.
