It’s also another advantage for those who want a minimalist look in their kitchen or bathroom.

Cons of an Undermount Sink

Undermount sinks are widely used for their quality and longevity and have some shortcomings. The potential drawbacks to undermounted sinks include:

More difficult to install

Installation of sinks must first be drilled into the surface of the sinks. Because undermount sinks only support solid surface countertops, the cutting may be difficult. Most countertops are built with specific cutouts. The installer has to install anchors to mount the new sink.

Upon installation, the sink is placed and secured with hidden metal clips. This anchor can be easily screwed into wood or stone or concrete, you could also use epoxy adhesive for this purpose. After this, the installation of the drains and other plumbing fixtures can be completed.

Bacteria can build up where the counter meets the sinks if not cleaned properly

The Undermount kitchen sink has a tiny gap between them and the counter. The opening is filled with silicone caulk, though the gaps often exist, allowing food particles to be absorbed. Similarly, a piece of caulking holds down an outlet on the counter above. It may contain gunk which turns black as it is filled with sand and mold.

An undermount Sink is only compatible with solid countertop materials

Undermount sinks require a precise countertop cutout and sink opening, which is not compatible with all countertop materials. While they look elegant and streamlined, they can be more challenging to install and may not be compatible with every countertop.

Counter materials that cannot support an undermount sink include laminate counters, tiles, and Formica.

Undermount sinks can be more expensive than drop-in sinks

One of the main reasons that undermount sinks are more expensive to install is that they require additional labor. Unlike drop-in sinks, undermount sinks must be drilled into the countertop’s surface, and anchors must be installed to mount the sink. Additionally, because undermount sinks use only solid material, cutting may be difficult, adding time and cost to the installation process.

Easy to clean the sink basin

Drop-in sinks are an excellent choice for those who want an easy sink cleaning. The smooth surface of a drop-in sink makes it easy to clean any spills or messes. Undermount sinks are more challenging to clean because of the crevice where the sink meets the countertop.

Cons of a drop-in sink

Drop-in sinks can be harder to clean around the sink’s edge on the countertop

One of the main reasons that drop-in sinks can be tough to clean around the edges is that they are not as streamlined as undermount sinks. The sink hangs over the countertop, creating a gap where gunk and bacteria can build up. Additionally, because there is less space between the countertop and the sink, it can be more challenging to clean all the areas around the sink.

Prone to water leakage

The seal between the sink and countertop is not always airtight, so water can seep underneath.

Bad aesthetics, not a good choice if you’re looking for a high-end design

Drop-in sinks are not the best aesthetics because they create a bulky and heavy look on the countertop. The sink’s rim sticks out from the countertop, making the basin look more extensive and more noticeable than an undermount sink.

They wobble if not installed properly

Additionally, since drop-in sinks are not attached to the countertop, they can move around or wobble when used. This can be particularly problematic if your kitchen is already cramped or small.
