Which towns do we cover in Gwynedd?
Supplies across most of Gwynedd 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. If you have bought a vanity unit for your Bangor bathroom, fit-only installation covers connecting the tap and waste and testing for leaks.
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
- Removal of the old basin and pedestal, or old vanity, and taking it away
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
Decisions to make first
Width
Compact units around 400 mm wide suit cloakrooms; family bathrooms often take 600 to 800 mm for one basin and 1200 mm or more for two.
Drawers or doors
Drawers keep things visible and reachable but lose some space to the trap. Doors give a deeper cupboard and cost less.
Wall-hung or floor-standing
Wall-hung units leave the floor clear and are easy to clean under, but need a strong wall. Floor-standing units hold more and suit weak or uneven walls.
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.
