A self-edging (top-mount) sink sits in an appropriately shaped hole, rough cut in the countertop (or substrate material) using a jigsaw or other cutter appropriate for the material at hand.They hang from the rim, which creates a fairly tight seal with the top surface of the countertop. This seal can be strengthened, if necessary, by clamping the sink from under the countertop.
Bottom-mount or undermount sinks are installed below the countertop surface.The edge of the countertop material is exposed at the hole created for the sink (so it must be a well-finished edge, not a rough-cut edge).The sink is then clamped to the bottom of the material.Especially with bottom-mounted sinks, a silicon-based sealant is often used to ensure a watertight joint between the sink and countertop material.Advantages of undermount sinks include superior ergonomics and a modern look; disadvantages include the additional cost of the sink and countertop.Also, no matter how carefully the cut is made, the result will be a small ledge or overhang at the interface with the sink.This creates an environment to trap dirt and allow bacteria to grow.The solid surface plastic material allows the sink to be made from the same plastic material as the countertop.These sinks can then be easily glued to the underside of the countertop material with the seams sanded smooth to create the usual invisible seams and completely eliminate any stain-prone seams between the sink and the countertop.In a similar manner, with stainless steel, the sink can be welded to the countertop; the seam is then sanded for the perfect concealed look.
The butler sink is a rectangular ceramic sink with rounded edges that is set into the countertop.There are generally two types of butler sinks:London sinks and Belfast sinks.In 2006, both types of sinks were typically 61 cm (24 in) wide, 46 cm (18 in) front to back, and 22.5 cm (8.9 in) deep.The London sink was originally shallower than the Belfast sink.(A plumbing guide from 1921 recommended that Belfast sinks be 38 cm (15 in) deep.).It has been suggested that this was because London had less access to fresh water (and thus a greater need to conserve it), but This theory is now controversial.The two sinks are more likely to serve different roles in the home.  But the difference is not usually present in the modern era, where both sinks are shallow now.The main difference between Belfast and London sinks then and today is that Belfast sinks are fitted with overflow weirs which prevent water from overflowing the edge of the sink by draining it into the waste pipe.
The farmer sink is a deep sink with a finished front.Placed on the countertop, the finished front of the sink remains exposed.This type of sink requires very little "reach" to access the sink.
A vessel sink is a freestanding sink, usually finished and trimmed on all sides, that sits directly on the furniture surface on which it is installed.These sinks are increasingly popular with bathroom designers for their wide variety of materials, styles and finishes to take advantage of.
Food and catering sinks:
Dimensions of catering sinks are generally compatible with standard-sized Gastronorm containers, which are the European standard for food containers.
