5 Steps of Installing Undermount Kitchen Sinks

Undermount kitchen sinks have become a front-runner in fixture options because of their seamless appearance and functionality. For anyone trying to create sleek, uncluttered countertop space that allows easy cleanup, follow the instructions below for installation of our artisan undermount kitchen sinks.

We advise that you seek a professional opinion from your installer for specifics on how best to install, taking into consideration your cabinet materials and other details that are unique to your project. For example, our best-selling farmhouse sinks with an exposed front apron may require redesigning your cabinets. Below are some general guidelines for installing standard undermount kitchen sinks. Undermount kitchen sinks1. Build a frame inside your cabinet on which the sink can rest

Many of our sinks are substantial, heavy, double basin models that have the capacity to hold lots of large dishes, pots, or pans. For this reason, we recommend that your contractor build a cleated or boxed-in frame on the inside of your cabinets that can support the rim of your sink. (This method opposes other under mounting techniques that involve adhering the sink rim directly to the countertop with epoxy.) The cleat should be placed so that when the sink is positioned on it, the top rim lays perfectly flush with the walls of the cabinet. The countertop will lie over the top of the sink.

Before placing the sink on the cleats, check to make sure the top rim is perfectly flat. If necessary, turn the sink over on a flat surface and use a rubber mallet to tap the metal down until it meets the floor.

2. Cut a hole in the countertop

When purchasing an artisan, handcrafted sink, we strongly advise waiting until your sink is in hand before making any cuts in your countertop rather than using a standard template. Artisan products require a tolerance of up to ½” in length and width, so you’ll want to make sure the correct sized hole is cut upon receipt of your actual sink.

Have a skilled craftsman cut a hole in your countertop to accommodate the size of the sink and fixtures, such as a faucet.

3. Clean everything

It’s important that you wipe down the top and bottom edges of the countertop, as well as the sink so that your silicone sealant is not sticking to dust or dirt, causing an insecure seal.

4. Place the sink

Place the sink on the cleats inside your cabinet. If drilling or cutting the sink rim is necessary, make sure to leave at least ¾” gap between the cut and any weld or seam in the sink. Feel free to drill through the rim of the sink to secure it to the cleats, to ensure it stays right in place.

5. Place your countertop on top

When the sink is positioned correctly on its cleats and dust wiped away, apply a continuous bead of clear silicone around the entire topside of the rim of the sink. Carefully lay your countertop on top of the sink, and wipe away any excess from underneath. Read the instructions on the silicone, and allow the necessary drying time before use.

With these tips in hand, you’ll be confident to install your new undermount kitchen sink successfully! As always, make sure to work with an experienced contractor when starting a remodeling project, and don’t hesitate to ask questions.
