Q: We recently moved into a new home, and the kitchen has a nice island area with a natural-stone countertop, but no sink!

I guess to save counter space or money the sink was never installed. We really want the sink — is this a complicated project? We have a basement under the kitchen, if that helps.

A: First, the good news is that you do have access under the island area. If you were on a concrete slab, that could have been a deal-breaker.

It’s a good idea to meet with your local building inspector before you start the project. This way, any necessary permits can be taken out.

Installing a new sink in your existing kitchen island can be a little complicated and could involve a few contractors. Basically, it may break down like this:

• The contractor needs to find or create an open pocket area in the cabinet base large enough for the sink and plumbing to be installed.

• A countertop stonecutter can then cut out a sink hole over the pocket area where a “drop-in” style of sink can be installed.

• The plumber can drill through the cabinet base and floor to run water and drain lines into the pocket area to connect the sink and faucet.

Prepare your patience and budget ahead of time, so that you don’t end up stranded on your kitchen island because of poor planning.
