Countertop Sink Installation Options

Self-Rimming Sinks

• A self-rimming sink is one of the easiest countertop sink options to install. It has a lip all around the top, which rests on the countertop when the sink is properly positioned in its cut-out hole. You will need to apply sealant around the join. The advantages of a self-rimming sink include its ease of installation, and the fact that it does away with the need for the hole in the countertop to be finished. The sink is simply placed in the cut-out and secured, with any rough edges in the cut-out being concealed by the overlapping lip.

Integral Sinks

• Integral sink countertop units are manufactured all in one piece, with the sink and the countertop being part of a continuous surface. They are very easy to install, and, depending on the material that they're made of, can be quite an economical option. Integral sink units are very easy to clean, since there are no raised areas or crevices where dirt can get trapped. Because there are no gaps between the sink and the counter to keep sealed, an integral unit is also easy to maintain.

Flush-Mounted Sinks

• A flush-mounted sink is installed so that the edge of the sink is level with the edge of the countertop. This creates the effect of an integral sink. Flush mounted sinks are somewhat harder to install than self-rimming or integral sinks as the top of the sink needs to be exactly flush with the countertop.

Under-Mounted Sinks

• Under-mounted sinks are recessed into the counter. They are held in place by clips secured to the underside of the counter. Under-mounted sinks are harder to install than self-rimming sinks, for example. Because the edges of the cut-out are visible above the edges of the sink, they need to be finished so as not to look rough or unsightly. This can increase the cost.

Materials

• Materials used for sinks include marble, glass, and various plastics. Many sinks are made from porcelain. Another common material is fiberglass. Countertops are often made from plastic laminate or polymer materials such as cultured marble. In bathrooms, countertops may be made from solid-surface, a durable material that can be buffed and sanded. They may also be composed of ceramic tiles. For integral units, cultured marble or solid-surface may be used. You can also find integral units made from glass.
