Semi Pedestal Basins

A semi pedestal basin, sometimes called a half pedestal basin semi pedestal sink, fixes to the wall and uses a shorter pedestal to conceal the pipework below. Here's what to know about choosing the right size, checking the fit and getting it installed.

 

Are semi pedestal basins good for small bathrooms?

Yes. As the pedestal stops above the floor, it keeps more of the floor visible and can make a small bathroom, en-suite, cloakroom or downstairs toilet feel less crowded. The clear space beneath can also make the floor easier to clean.

The basin itself fixes securely to the wall. The semi pedestal normally conceals the plumbing rather than supporting the basin's weight (unless the manufacturer's instructions state otherwise).

 

Will a compact semi pedestal basin feel too small?

Not necessarily. A small semi pedestal basin can still give you plenty of room at the bowl, so check the bowl width and depth as well as the overall size. A compact design can provide enough room for comfortable handwashing without extending too far into the room.

Also check the basin's fitted height, the dimensions of the half pedestal and the clearance from doors, toilets and other fittings. These measurements will give you a better idea of how the complete basin will fit than its width alone.

 

What do I need to fit a semi pedestal basin?

Choose a basin and semi pedestal that are designed to work together, or check that both components come as a compatible set. You will also need a wall that can support the basin and fixings suited to the wall construction.

Check that the supply pipes, waste pipe and trap will fit within the space concealed by the semi pedestal. Many designs need the pipework to enter the wall within this area. Pipes that currently run into the floor may remain visible or need to be rerouted.

Fixings, traps and basin wastes can vary between products, so check what comes with your chosen semi pedestal basin before ordering anything separately.

 

Are semi pedestal basins easy to install?

Installation can be more involved than it first appears because the basin must be level and securely fixed to the wall while the plumbing fits neatly into a restricted space behind the semi pedestal.

Follow the manufacturer's instructions when positioning and securing both components. Do not rely on the semi pedestal to support the basin unless it is specifically designed to do so. Ask a qualified installer to complete the work if you need to move the pipework, are unsure whether the wall can support the basin or cannot confirm which fixings to use.
