Find the Perfect Undermount Bathroom Sinks

Undermount bathroom sinks are the most common type of bathroom sink available on the market. An undermount bathroom sink is simple in design and is installed underneath a bathroom counter or a bathroom vanity. Once installed, usually using undermount metal clips or brackets, the sink is seamlessly integrated to the counter space with the interior wall of the undermount sink usually parallel to the edge of the cutout. This set-up allows for endless possibility with your choice of a vanity or countertop.

Undermount Bathroom Sink Designs

A traditional undermount bathroom sink is usually rectangular or oval, however, options such as square undermount bathroom sinks, oval sinks and speciality shape sinks have increasingly become top choices for experienced interior designers and motivated home owners. Rectangular and oval undermount sinks are typically the easiest to incorporate into a design and help maximize both the counter space while maintaining an adequate basin size.

The majority of the undermount bathroom sinks are made of a white ceramic material, yet, there are models that are made of metal and solid surface. However, the former are much less common. With the designs of these sinks being relatively simple, the most common questions when purchasing an undermount bathroom sink are typically as follows:

What Size Undermount Bathroom Sink Should I Purchase?

The correct size of an undermount bathroom sink can be determined by the size of the counter or vanity. First determine the size of the bathroom vanity by measuring your bathroom and determining a comfortable size for the vanity. Once this is determined, it is important to decide on how much counter space is needed. Typically, we recommend a minimum of 4” of space in all directions, however, the space on the left and right side can be substantially larger. Determine the size of counter space you need then subtract from the overall dimensions of the counter to determine the size of the undermount bathroom sink you will need. Once you have that dimension, you can find the perfect sink. Just keep in mind, the interior dimensions of an undermount sink should be the dimensions you look at when shopping (and not the exterior dimensions).

The most common undermount bathroom sinks generally are between 17” and 20” wide.

What Shape Undermount Bathroom Sink Should I Purchase?

The perfect shape of an undermount bathroom sink should be determined by two factors; your desired design and the counter space that you need. The first factor, design, is typically a personal preference yet there are some important aspects to consider. The bathroom should have a harmonized design and it’s important to consider consistency with shapes. Accordingly, if your fixtures are round, we recommend considering a round or oval undermount bathroom sinks. While, if your fixtures such as your accessories, faucet and toilet are rectangular, a rectangular or square undermount bathroom sink would likely be a better option. The second factor to consider is space whereas an oval undermount bathroom sink would help you maximize your counter space, which can be very important especially for congested or smaller bathrooms.

Top 3 Reasons to Consider an Undermount Bathroom Sink

  • Undermount bathroom sinks work with every vanity or counter. Of course, you need to select the correct size and shape, but ultimately you will always find a sink that works.
