An undermount sink is one where the level of the sink is sunken down to a level below the the plain of the countertop. In other words, it looks as if the countertop naturally falls off into the sink. They are very popular in both bathrooms and kitchens.

An undermount sink is not a new design, but rather a resurgence of an old idea that has become popular again as technology to pull of the effect has improved and become affordable. The idea is that it appears more natural and more seamless and sleek for there to be no crown around the rim of a sink. While some may not like the look, many others have the opposite opinion. An undermount sink, properly placed, can become a centerpiece kitchen sink or bathroom sink.

In most cases, it may be wise to have an undermount sink installed by a professional. It must be attached with a space-age bonding agent, such as silicone caulk, precisely to the underside of the countertop in a way that will not cause it to leak. The new materials available make it relatively easy to keep an undermount sink in place. The silicone cures quickly and, once it is dry, is capable of holding a tremendous amount of weight.

The design of an undermount sink may cause some to shy away from installing one, on the fears it will leak. Indeed, those fears are easy to understand. You are trusting, in some cases, caulking to hold in place more than 100 pounds (54 kg) of weight when an undermount sink is full of water and has a disposal attached. However, silicone caulk is more than able to handle the job, if it is applied properly.

For those interested in an undermount sink for a kitchen or bathroom, there are many different options from which to choose. There are double bowls, unequal double bowls and single bowls. Most kitchen sinks will use a double bowl. Bathrooms are ideal for single bowls.

If installing an undermount sink by yourself, the first thing to do is to make sure you read all directions and follow them as closely as possible. The underside of the counter, where the bonding agent will be, must be clean and free of dust and debris. Without making sure this is done, the sink can pull away from the counter. Also, it is good to wait 24 hours after setting the sink before using it. One of the most common mistakes made is not giving the bonding agent enough time to set before beginning use.
