Which towns do we cover in Gwent?
Water hardness varies across Gwent: some supplies are soft, others moderately hard or hard. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier. We quote vanity unit work in Newport after seeing the wall and pipework, so any re-tiling is on the quote from the start.
What the job includes
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- Patching or re-tiling the wall where the old basin left gaps
- Testing for leaks and checking the trap holds its seal
- A check that the wall can carry a wall-hung unit, with fixings to suit solid or stud walls
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
- Fitting the unit level, with the basin sealed to the top and the top sealed to the wall
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.
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.
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.
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.
