Installing a drop-in sink is a simple project, although care must be taken when cutting the opening in the counter; this step is delicate and requires dexterity. Nonetheless, any cutting inaccuracies can usually be overcome.

This guide provides instructions on installing a sink assuming that the plumbing is in place and ready to connect up. Drop-in sinks, whether with a single, double or triple bowl, are all equally quick to install because only one cut needs to be made. A sink made from cast iron or another heavy material will be more difficult to lower into the counter; for this job you will need a helper.

Before Assembly


Do as much of the work as you can above the countertop to avoid working under it where space is tight. Use the drain holes to support the sink when inserting it into the opening.

If the drains are not exactly aligned with the new sink, use angle fittings (or elbows) of different sizes to make the necessary connections.

Most kitchen sinks are made of stainless steel, though some are made of cast iron, which is much heavier. For heavy sinks, the countertop may need to be reinforced first.


Wear safety glasses when working under the sink and protective gloves when using the jigsaw.
