An undermount sink is as handsome as it is practical; the countertop is easier to clean and no residue can accumulate under the sink edge.
This type of undermount installation involves a specific technique and a sink designed especially for this purpose, often available by special order only.
The sink is supported from below with special mounting clips glued under the countertop. This structure is strong enough to support the weight of the sink when filled with water.
An undermount sink is more complicated to install than a drop-in sink. Follow these steps and the manufacturer’s instructions carefully, and if in doubt, call a professional installer.
