A sink that sits entirely on top of the counter is called a vessel sink. Often resembling a large basin or bowl, these are designed to sit directly on the vanity, showcasing the entire sink body as a decorative focal point.
A vessel sink is also known as a bowl sink.
It is made to sit on top of the countertop rather than underneath it, as is the case with normal sinks.
There are three main types of kitchen sinks: drop-in sinks, undermount sinks and farmhouse sinks. These types describe how the sink is mounted and installed.
Because vessel sinks sit on top of the vanity, they often eat into both visual and physical space, especially under the counter, where plumbing may be routed higher. This can reduce drawer depth or limit cabinet storage.
An above-counter bathroom sink, commonly called a vessel sink, sits completely on top of the vanity rather than being recessed. This modern, sculptural design instantly creates a bold focal point and is available in a wide variety of materials, including ceramic, glass, stone, and copper.
Drop-in sinks, also called top-mount or self-rimming sinks, sit on top of the countertop with a visible rim surrounding the basin. The edge rests on the counter surface and the basin drops into a cutout.
While undermount sinks offer a seamless look and let you sweep crumbs straight into the basin, they have notable drawbacks. They are more expensive, restrict your countertop material choices (requiring heavy, water-resistant solid surfaces like granite or quartz), and can hide mold or debris along the unseen rim.
Countertop sinks, also known as drop-in basins, are the more traditional option for bathroom vanities. As the name implies, these sinks are designed to be mounted on top of the countertop, with the rim of the sink resting on the surface of the counter.
Neither is universally better. Undermount sinks offer a modern look and easier cleaning, while overmount sinks are more affordable and easier to install.
A countertop sink sits on top of a bathroom cabinet, worktop or vanity unit, so they are also a great space saving or storage option if needed.
Let's get the basics all sorted out so you can start to hone in on the right bathroom sink for you.
The easiest sink to keep clean is an undermount, single-basin stainless steel sink. Because it has no lip over the counter to trap debris, zero divider walls to scrub around, and a non-porous finish, it resists stains and bacteria.
Belfast sinks are often seen as a luxury kitchen sink, because they're commonly used in large farmhouse kitchens - but can suit any style and kitchen size. Belfast sinks are far heavier than many other types of sink such as stainless steel, as they're made of ceramic.
An undermount sink is one that's installed underneath the countertop instead of on top like the more traditional “drop-in” style sink. It's held in place by a strong adhesive.
Overmount kitchen sink basics
An overmount sink is placed into a cutout made into your benchtop. The lip sits over the cutout and rests on your benchtop. The edges are caulked, usually with silicone, to give it a waterproof seal. Your benchtop takes the weight of the sink and everything you put in there.
A countertop basin, often referred to as a vessel or sit-on basin, is a type of wash basin that sits entirely on top of a counter or vanity unit. Unlike traditional basins that are recessed or wall-mounted, these basins make a bold design statement with their elevated and freestanding style.
Top mount (or drop-in) sinks are less common in modern, high-end designs because undermount sinks offer a sleeker, continuous look. However, they are still highly practical, especially if you are on a budget, doing a DIY install, or using laminate countertops.
Due to their design, top mount sinks tend to trap food and debris between the sink and the countertop, which can be difficult to clean. Additionally, the rim of the sink can get in the way when trying to wash large pots or pans. Finally, top mount sinks tend to look less modern and sleek compared to flush mount sinks.
Yes, undermount sinks can get mold. Because they sit directly beneath the countertop, the hidden lip or seam connecting the sink to the underside of the counter frequently traps moisture, food particles, and bacteria, creating an ideal environment for mold and mildew to grow.
A sink that sits on top of the counter is called a vessel sink.
Because bathrooms are hot, humid, and prone to temperature fluctuations, it is best to keep medications, electronics, and paper goods out of them. High moisture levels degrade products, encourage mold and mildew, and can cause metal items to rust or tarnish.
In British English, a sink is primarily used in the kitchen. For the appliance in a bathroom used for washing hands and brushing teeth, British speakers more commonly say washbasin (or just basin).
Do Undermount Sinks Fall? Yes – undermount sinks can fall for a number of reasons, including: Too much weight or stress: Excessive weight or stress can cause it to come down. Adhesive deterioration: Since adhesives break down over time, a sink can fall if it's no longer secured.
A stainless steel sink is the most durable and low-maintenance kitchen sink as they are resistant to heat, stains, and scratches. What's more, they are also some of the most versatile sinks coming in a variety of styles and sizes meaning they fit in most kitchens easily no matter the size or style.
