Working in Carmarthen
In Carmarthen we cover SA31; we also cover Llanelli, 13.5 miles away, and Ammanford.
Carmarthen gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We quote vanity unit work in Carmarthen after seeing the wall and pipework, so any re-tiling is on the quote from the start. Landlords in Carmarthen can have a worn basin replaced with a vanity unit in half a day to a day.
Supplies across most of Dyfed 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
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- A new tap, trap and the correct slotted or unslotted waste for the basin
- Testing for leaks and checking the trap holds its seal
- Removal of the old basin and pedestal, or old vanity, and taking it away
Decisions to make first
Basin type
An inset or semi-recessed basin, a one-piece moulded top, or a countertop basin on a worktop. Countertop basins need a tall tap or a wall-mounted one.
One basin or two
Two basins help a busy household if the wall is long enough. In a smaller room, one basin with a longer top often works better.
Rules that apply in Wales
Wales follows the same water fittings regulations as England. Its own Part P covers more electrical work, so a lit vanity or mirror should be connected by a registered electrician.
