Drop-In Sink
A drop-in sink (also called a self-rimming or top-mount sink) is installed by dropping the sink basin into a pre-cut hole in the countertop, with the sink's rim resting on the counter surface. This visible rim creates a raised edge around the sink perimeter, making drop-in sinks the most straightforward and budget-friendly sink installation type.
The installation simplicity and forgiving nature make drop-in sinks popular for DIY renovations and builder-grade homes. While they lack the seamless look of undermount sinks, modern drop-in designs have evolved with slimmer profiles and attractive finishes that complement a wide range of kitchen and bathroom styles.

Placement & Usage Tips
Ensure the cutout is precise—gaps cause water infiltration and support issues. Use a high-quality silicone sealant around the rim to prevent leaks. Position faucet holes according to your chosen faucet before cutting the counter.
💡 Pro Tip
The rim catches water and debris that would otherwise be wiped directly into an undermount sink. Keep the rim-counter junction clean and re-seal periodically to prevent water damage. Choose sinks with narrow, low-profile rims for a more contemporary look.
