Which towns do we cover in Dorset?
Most of Dorset has hard water. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. 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 Bournemouth bathroom, fit-only installation covers connecting the tap and waste and testing for leaks.
What the job includes
- Removal of the old basin and pedestal, or old vanity, and taking it away
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
- Patching or re-tiling the wall where the old basin left gaps
- A check that the wall can carry a wall-hung unit, with fixings to suit solid or stud walls
- Fitting the unit level, with the basin sealed to the top and the top sealed to the wall
- Testing for leaks and checking the trap holds its seal
Decisions to make first
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.
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.
Rules that apply in England
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.
In England, the tap and supply pipework come under the Water Supply (Water Fittings) Regulations 1999. A new waste connection to the soil stack can be Part H work, and adding a light to the unit or above it is notifiable under Part P.
