What does a new vanity unit cost in Cardiff?
For Cardiff, our guide range for a new vanity unit is £350 to £1,400 including VAT. We adjust the national guide for Wales, where prices are typically about 7% below the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Cardiff
We cover every part of Cardiff, including CF10, CF11 and CF24, and nearby Penarth (2.9 miles) and Caerphilly (6.7 miles).
In a city the size of Cardiff, parking and access for a skip are worth sorting before the start date — we will ask at the survey. Landlords in Cardiff can have a worn basin replaced with a vanity unit in half a day to a day. If your Cardiff water is hard, a tap with a removable aerator and a smooth one-piece basin top are easier to keep clean.
Most of South Glamorgan has moderately hard water. 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.
What the job includes
- Testing for leaks and checking the trap holds its seal
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
- A check that the wall can carry a wall-hung unit, with fixings to suit solid or stud walls
- Patching or re-tiling the wall where the old basin left gaps
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.
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.
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.
