Countertop Basins

Also known as vessel basins, countertop basins are one of the most popular basin designs that can make a big impact in your bathroom. If you are on the fence about opting for a countertop basin, these are some of the things that you should consider.

 

What is a countertop bathroom sink?

A countertop bathroom sink sits on top of a vanity unit or worktop rather than being fitted into it. They're available in round, oval, square and rectangular shapes.

 

Can I fit a countertop basin on any vanity unit or worktop?

Not every surface will be suitable. The vanity unit, worktop or floating basin shelf, must be flat, stable and able to support the basin's weight. It also needs enough space for both the basin and tap, with suitable access for the waste and pipework below.

You can fit some countertop basins to bespoke or repurposed furniture, but check that the surface can withstand moisture and be cut safely without weakening it. If you are unsure, ask a qualified installer to assess it before making any alterations.

How do I choose the right size countertop basin?

Measure the width and depth of your vanity unit, worktop or shelf, then compare these with the basin's overall dimensions. Allow enough surface around the bowl for the tap and any toiletries, as well as suitable clearance from walls and nearby fittings.

For comfortable everyday use, aim for the top rim of the fitted basin to sit around 80 to 85cm from the floor. Remember to include the height of the unit and worktop when working this out.

The bowl's internal size and depth also affect how comfortable it is to use. A compact countertop basin can suit a smaller bathroom or cloakroom, but it still needs enough room for handwashing. The bowl's shape and depth, along with the tap's position and flow, can affect splashing.

 

What tap and waste do I need for a countertop basin?

If the basin has no tap hole, you will usually need a tall basin mixer fitted to the worktop or a wall mounted basin tap. If it has an integrated tap hole, a standard basin mixer may be suitable.

Check the tap's height, spout reach and water pressure requirements before ordering. The water should flow towards the centre of the bowl, with enough clearance beneath the spout for comfortable use. A deck mounted tap will also need enough space behind or beside the basin.

The correct waste depends on whether the basin has an overflow. A basin with an overflow usually needs a slotted waste, while one without an overflow needs an unslotted waste. Our guide to slotted and unslotted basin wastes explains the difference. Check the product details too, as taps and wastes may need to be purchased separately.
