Sink - Styles

Styles

Self-rimming (top-mount) sinks sit in appropriately shaped holes roughly cut in the countertop (or substrate material) using a jigsaw or other cutter appropriate to the material at hand and are suspended by their rim. The rim then inherently forms a fairly close seal with the top surface of the countertop, especially when the sink is clamped into the hole from below.

Bottom-mount or under-mount sinks are installed below the countertop surface. The edge of the countertop material is exposed at the hole created for the sink (and so must be a carefully finished edge rather than a rough cut). The sink is then clamped to the bottom of the material from below. Especially for bottom-mount sinks, silicone-based sealants are usually used to assure a waterproof joint between the sink and the countertop material. The advantage of an undermount sink is that it gives a contemporary look to the kitchen but the disadvantages are extra cost in both the sink and the counter top. Also, no matter how carefully the cut out is made, the result is either a small ledge or overhang at the interface with the sink. This can create an environment for catching dirt and allowing germs to grow.

Solid-surface plastic materials allow sinks to be made of the same plastic material as the countertop. These sinks can then easily be glued to the underside of the countertop material and the joint sanded flat, creating the usual invisible joint and completely eliminating any dirt-catching seam between the sink and the countertop. In a similar fashion, for stainless steel, a sink may be welded into the countertop; the joint is then ground to create a finished, concealed appearance.

A butler's sink is a rectangular ceramic sink with a rounded rim which is set into a work surface. There are generally two kinds of butler's sinks: The London sink and the Belfast sink. In 2006, both types of sinks usually were 61 centimetres (24 in) across and 46 centimetres (18 in) front-to-back, with a depth of 22.5 centimetres (8.9 in). London sinks were originally shallower than Belfast sinks. (One plumbing guide in 1921 suggested that the Belfast sink was 38 centimetres (15 in) deep.) This was primarily because London had less access to fresh water (and thus a greater need to conserve water). But that difference usually does not exist in the modern era, and both sinks are now shallow. The primary difference both in the past and today between a Belfast and London sink is that the Belfast sink is fitted with an overflow weir which prevented water from spilling over the sink's edge by draining it away and down into the wastewater plumbing.

A farmer's sink is a deep sink that has a finished front. Set onto a countertop, the finished front of the sink remains exposed. This style of sink requires very little "reach-over" to access the sink.

A vessel sink is a free-standing sink, generally finished and decorated on all sides, that sits directly on the surface of the furniture on which it is mounted. These sinks have become increasingly popular with bathroom designers because of the large range of materials, styles and finishes which they can show to good advantage.
