There are several different types of vanity sinks that are popular in bathroom remodels and renovations:
Drop-in vanity sink: also known as self-rimming or top-mount sinks, these sinks are designed to sit on top of the countertop and have a lip or rim that holds them in place. They are easy to install and are available in a variety of materials, sizes and designs.
Undermount vanity sink: these sinks are installed beneath the countertop, giving the countertop a seamless look. They are typically more difficult to install than drop-in sinks, but they are considered to be more elegant and modern-looking.
Pedestal vanity sink: This type of sink sits on top of a pedestal base, leaving the space underneath the sink open. They are a traditional and elegant option, but do not provide counter space or storage.
Wall-mounted vanity sink: These sinks are hung on the wall and are not supported by countertop or cabinetry. This style gives the bathroom a modern, open look and can save some space.
Vessel vanity sink: These sinks sit on top of the countertop and are available in a wide variety of designs, such as glass, porcelain, and stone. They can be considered a decorative element in the bathroom, and are also easy to install.
Corner vanity sink: As the name suggests this sink is designed to fit into corner of the bathroom, to make use of an otherwise wasted space.
Console vanity sink: These sinks sits on top of legs, that can be metal, wood or any other material, giving the bathroom a more retro or vintage feel.
Integrated vanity sink: These sinks are integrated into the countertop, resulting in a seamless, cohesive look, they are not as common as other type and is more difficult to install.
