Swapping a pedestal basin for a vanity unit is one of the quickest changes that makes a bathroom easier to live with. The pipes disappear, there is somewhere for spare toilet rolls and cleaning things, and a countertop gives you space a pedestal never does. The work usually takes half a day to a day, although tiles that stopped behind the old basin often need patching.
Supplying and fitting a standard floor-standing or wall-hung vanity, including taking out the old basin and connecting a new tap and waste, typically costs £400 to £1,000 including VAT. If you have bought the unit yourself, fitting it costs £150 to £350. Double basins, long runs and stone or solid-surface tops cost £1,000 to £2,500, with re-tiling behind where needed.
What does a new vanity unit with us include?
- Removal of the old basin and pedestal, or old vanity, and taking it away
- 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
- A new tap, trap and the correct slotted or unslotted waste for the basin
- 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

What do you need to decide?
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.
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.
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.
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.
