Installing or replacing a vanity unit is a common bathroom job that combines plumbing connections with furniture fitting. The labour involved usually depends on access to pipework inside the cabinet, the size of the unit, and whether the existing basin and pipe connections need adjusting. Some installations are straightforward, while others require small plumbing modifications to fit neatly inside the unit.
Below is a general guide to labour costs for vanity unit installation.
Vanity Unit Installation (With Basin)
Installing a vanity unit with a basin normally takes longer because the unit needs to be positioned, secured, and connected correctly inside the cabinet. Access to pipework inside vanity units can sometimes be restricted, which may increase the installation time.
Typical labour cost: £160 — £320
Time: around 2–4 hours
Vanity Unit Replacement
Replacing an existing vanity unit with a similar unit in the same position is usually straightforward when the existing pipework connections can be reused.
Typical labour cost: £160 — £320
Time: around 2–4 hours
When costs can vary
Vanity unit installation can take longer depending on the condition of the existing plumbing and accessibility inside the cabinet. Additional time may be required if:
the waste pipe needs replacing
hot and cold pipework needs adjusting
isolation valves need changing
fittings inside the unit need modifying
working space inside the cabinet is limited
All prices shown are labour-only estimates intended as a general guide. The exact cost is confirmed once the job has been seen and the existing installation checked.
