Drop-In Bathroom Sinks

Drop-in bathroom sinks sit in a cutout in the countertop, with a rim that rests on the surface and covers the cut edge. That makes them a straightforward choice for a new vanity and an easy option when you are replacing an older sink without changing the counter, since the rim hides small imperfections around the opening. This page brings together drop-in lavatory sinks from brands such as Kohler, American Standard, TOTO, Cheviot and Victoria + Albert, with examples like the Tahoe rectangular drop-in bathroom sink, the MINI OVAL Drop-In Sink 1102 and the Promenade Self Rimming Lavatory.

Because the rim stays visible, the shape and colour of the sink matter as much as the bowl itself. Colour options on this page include White, Biscuit, Dune, Sea Salt and Ice Grey, so you can keep a classic white look or warm up a neutral counter. Before you choose, measure the cabinet and the countertop opening, confirm the faucet hole layout you need, and think about how the rim will sit against your counter material. A few minutes with a tape measure now saves a return trip and keeps installation day simple.

What to check before you buy

• Measure the cabinet and the cutout. Check the inside width and depth of the vanity cabinet, and if you are reusing a counter, measure the existing opening. The sink's overall dimensions and its cutout template both need to fit.
• Confirm the faucet hole configuration. Drop-in sinks are made for a particular faucet layout, such as a single centre hole or widespread spacing. Match the sink to the faucet you plan to use, not the other way around.
• Look at the rim and your counter. The rim sits on top of the counter and will be seen, so consider its profile and how it will look against laminate, stone or solid surface. A flat, clean counter edge around the cutout gives the best seal.
• Choose the colour to suit the room. Options on this page include White, Biscuit, Dune and Ice Grey. If you are matching a toilet or tub, compare the colour names closely, since white shades can differ between brands.

Frequently asked questions

What is the difference between a drop-in and an undermount bathroom sink?

A drop-in sink rests on top of the counter with a visible rim, while an undermount attaches beneath the counter so the edge of the cutout is exposed. Drop-in sinks are generally easier to install and work with a wider range of counter materials; undermounts give a cleaner look but need a finished cutout edge.

Can I replace an old drop-in sink without changing my countertop?

Often, yes. Measure the existing cutout carefully and compare it to the template of the new sink, and make sure the faucet hole layout suits the faucet you want to use.

Does a drop-in sink need to be sealed?

Yes. A bead of silicone under the rim keeps water from getting beneath the sink and into the cabinet, and some models also use clips underneath to hold the sink firmly in place.
