Bar sinks are mostly under mounted or wall deck and installed in restaurants or bars for quick access to water and cleaning items. They are made in varying sizes, shapes, designs and materials. Regular bar sinks are usually made from stainless steel and ceramic as these are the most inexpensive types. Others use glass materials, which are really expensive as they are hand blown and can be purchased free standing.
Under mount small bar sink is installed beneath the counter, where a waterproof sealant is used to prevent water from seeping under the side of the counter. Vessel bar sink is also a popular choice. You simply have to place these on top of the counter where the faucets are attached to the walls. Before purchasing a bar sink, you should consider the measurement of the holes in the counter. Even though there are standard sized holes that fit most counters, it is still best that you get the right measurement of the space beforehand. Small bar sinks can be very hard to fit if the counter has large holes. At the same time, a bar sink with larger holes may require you to enlarge the holes in the space if these are not large enough.
