A pedestal lavatory sink brings a touch of elegance and charm to the home, and because it takes up less space than a vanity unit, it is ideal for smaller bathrooms.

The following project shows how to install a pedestal lavatory sink, step by step. This is an inexpensive project that can be accomplished in a day. It is best to work with a helper, as the parts can be very heavy. The main difficulty lies in attaching the washbasin to the wall at the right height. This part of the job requires precision and dexterity.

Before Assembly


Turn off the water supply by closing the shut-off valves under the sink. If there are no shut-offs, close your home's main water valve.
If the drain pipes under the sink are not exactly where you need them, use angle fittings (elbows) of different sizes to make the necessary connections.
