What is a Drop-in Sink?

A drop-in sink is a type of sink that is designed to be installed directly into a pre-cut hole on the surface of a countertop.


A drop-in sink, also known as a top-mount or self-rimming sink, is distinguished by its method of installation. This type of sink is designed to fit into a precisely cut hole in the countertop, with the sink's rim or lip sitting atop the counter surface, securing it in place. The weight of the sink rests on this rim, which also serves to prevent water from seeping underneath. Drop-in sinks are popular for both their ease of installation and their versatility, fitting well into a variety of kitchen and bath designs.

One of the most appealing aspects of drop-in sinks is their compatibility with almost any type of countertop material, including laminate, tile, and solid surface options. The installation process is relatively straightforward and can be accomplished by homeowners as a DIY project, or by professionals quickly and with minimal disruption. The sink's rim not only aids in its installation but also contributes to its design appeal, available in various finishes and materials to complement different decorating principles and elements.

However, some might find the raised rim of a drop-in sink less desirable from a design or functional perspective. Unlike undermount sinks, which allow for easy countertop wiping directly into the sink, the rim of a drop-in model can catch debris. Despite this, drop-in sinks remain a popular choice for renovations and new builds alike, due to their affordability and wide range of styles.


Drop-in sinks are commonly found in kitchens and bathrooms. They are chosen for remodels, new constructions, and as replacements for outdated or damaged sinks. The variety of materials, such as stainless steel, porcelain, and composite, means there's a drop-in sink to match virtually any interior design style.


  • Can a drop-in sink be installed in any type of countertop?

    Yes, drop-in sinks can be installed in virtually any countertop material, including laminate, granite, marble, and solid surface options.

  • Are drop-in sinks easy to install?

    Yes, the installation of drop-in sinks is straightforward. With a pre-cut hole, homeowners can often undertake this as a DIY project, although professional installation is quick and not overly disruptive.

  • How do drop-in sinks compare to undermount sinks?

    Drop-in sinks have a rim that sits atop the countertop, making them easier to install but potentially harder to clean around the edges. Undermount sinks are mounted below the counter, offering a sleeker look and easier countertop cleaning but require more precise installation.

Practical Application

When choosing a drop-in sink for your kitchen and bath, consider the material and finish to match your overall design theme. Ensure your countertop has been accurately measured and the hole cut to fit the dimensions of your chosen sink. Additionally, pay attention to the sink's depth and size to meet your practical needs and preferences. A sealant should be applied around the rim during installation to prevent water damage.
