Installing An Undermount Sink
Friday, October 16th, 2009An undermount sink can be a beautiful choice for the home. These are the sinks that are underneath the countertop so you don’t see the lip of the sink. It’s a style that highlights the beauty of the countertop giving the edges a sharp, clean appearance. These sorts of sinks can really set countertops made of marble, stone and granite extremely well.
The nature of the undermount sink means that the surrounding countertop is easy to keep clean. You can simply sweep crumbs straight into the sink without having to worry about them becoming caught on the lip of the sink.
The sink needs to be installed properly for it to be leak-free. It can last for decades without one leak. The undermount sink should be installed using silicone caulk and very strong epoxies. Then they stay in place with metal anchors that are attached to the underside by glue.
To install the undermount sink, it is best to have a professional actually cut the hole. It should be noted that undermounted sinks should only be installed under a solid surface, a countertop made of wood or a laminate finish would constantly run the risk of getting wet and this would lead to water damage. For this reason specialist stone cutters would be needed to perform the job of cutting the hole for the sink, something that is best left to the experts.
Use the silicone caulking around the hole just cut and then position the sink in its’ proper place. Then the screws should be tightened. Any caulking should be wiped off if it oozes out.
This is the best time for have the faucet holes drilled while working with the underside of the sink. Then turn everything over and attach it to the base counter. The manufacturer's directions should be followed if screws, clips or adhesives are needed.
Now that the sink is where you want it, the drain needs to be installed next. Plumber's putty should be used on the bottom of the drain and then needs to be pushed into the drain opening. Tighten the lock nut to hold it in place.
The undermount sink project should be put on hold overnight to let the putty and caulking set up. The next day you can attach the water supply lines to the faucet stems. Now the S trap and drainpipe should be attached to the bottom of the sink and drainpipe.
The undermount sink is ready for use, and is an attractive addition to the home. When the water is turned on, there should be a good check for leaks. If there aren't any, then the job is done.
The undermount sinks come in a single, double or even triple bowl style, so there are many choices for that special look in the kitchen. They are also available in a wide variety of shapes and sizes. You’re not going to be limited simply because you want the clean lines of a sink hidden below the level of the countertop.
