Which towns do we cover in Dyfed?
Most of Dyfed 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. We quote vanity unit work in Llanelli after seeing the wall and pipework, so any re-tiling is on the quote from the start.
What the job includes
- Testing for leaks and checking the trap holds its seal
- A new tap, trap and the correct slotted or unslotted waste for the basin
- Patching or re-tiling the wall where the old basin left gaps
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- Fitting the unit level, with the basin sealed to the top and the top sealed to the wall
- Removal of the old basin and pedestal, or old vanity, and taking it away
Decisions to make first
Waste and overflow
A basin with an overflow takes a slotted waste; one without needs an unslotted waste, often a push-button 'click-clack' type.
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.
Drawers or doors
Drawers keep things visible and reachable but lose some space to the trap. Doors give a deeper cupboard and cost less.
Rules that apply in Wales
Replacing a basin with a vanity unit does not need planning permission or building regulations approval. The new tap must meet the water fittings rules, including protection against backflow, and the waste should connect to the existing drainage through a proper trap. If the unit has a light, or a lit mirror goes above it, the electrical work must suit the zone it sits in under BS 7671 and be RCD protected.
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.
