Different sinks style
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. Advantages of an undermount sink include superior ergonomics and a contemporary look; disadvantages include 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.
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.

Sinks material
Sinks are made of many different materials. These include:
Ceramic;
Concrete;
Copper;
Enamel over steel or cast iron;
Glass;
Granite;
Marble;
Nickel;
Plastic;
Polyester;
Resin washbasin;
Soapstone;
Stainless steel;
Stone;
Terrazzo;
Wood;
Stainless steel is commonly used in kitchens and commercial applications because it represents a good trade-off between cost, usability, durability, and ease of cleaning. Most stainless steel sinks are made by drawing a sheet of stainless steel over a die. Some very deep sinks are fabricated by welding. Stainless steel sinks will not be damaged by hot or cold objects and resist damage from impacts. One disadvantage of stainless steel is that, being made of thin metal, they tend to be noisier than most other sink materials, although better sinks apply a heavy coating of vibration-damping material to the underside of the sink.
Enamel over cast iron is a popular material for kitchen and bathroom sinks. Heavy and durable, these sinks can also be manufactured in a very wide range of shapes and colors. Like stainless steel, they are very resistant to hot or cold objects, but they can be damaged by sharp impacts and once the glass surface is breached, the underlying cast iron will often corrode, spalling off more of the glass. Aggressive cleaning will dull the surface, leading to more dirt accumulation. Enamel over steel is a similar-appearing but far less rugged and less cost-effective alternative.

Solid ceramic sinks have many of the same characteristics as enamel over cast iron, but without the risk of surface damage leading to corrosion.
Plastic sinks come in several basic forms:
Inexpensive sinks are simply made using injection-molded thermoplastics. These are often deep, free-standing sinks used in laundry rooms. Subject to damage by hot or sharp objects, the principal virtue of these sinks is their low cost.
High-end acrylic drop-in (lowered into the countertop) and undermount (attached from the bottom) sinks are becoming more popular, although they tend to be easily damaged by hard objects - like scouring a cast iron frying pan in the sink.
Plastic sinks may also be made from the same materials used to form "solid surface" countertops. These sinks are durable, attractive, and can often be molded with an integrated countertop or joined to a separate countertop in a seamless fashion, leading to no sink-to-countertop joint or a very smooth sink-to-countertop joint that can not trap dirt or germs. These sinks are subject to damage by hot objects but damaged areas can sometimes be sanded-down to expose undamaged material.
Soapstone sinks were once common, but today tend to be used only in very-high-end applications or applications that must resist caustic chemicals that would damage more-conventional sinks.
Wood sinks are from the early days of sinks and baths were made from natural teak with no additional finishing. Teak is chosen because of its natural waterproofing properties – it has been used for hundreds of years in the marine industry for this reason. Teak also has natural antiseptic properties, which is a bonus for its use in baths and sinks.
Glass sinks: A current trend in bathroom design is the handmade glass sink (often referred to as a vessel sink) which has become fashionable for wealthy homeowners.
Stone sinks have been used for ages. Some of the more popular stones used are: marble, travertine, onyx, granite, and soap stone on high end sinks.
Glass, concrete, and terrazzo sinks are usually designed for their aesthetic appeal and can be obtained in a wide variety of unusual shapes and colors such as floral shapes. Concrete and terrazzo are occasionally also used in very-heavy-duty applications such as janitorial sinks.
Sinks history
The washstand was a bathroom sink made in the United States in the late 18th century.The washstands were small tables on which were placed a pitcher and a deep bowl, following the English tradition. Sometimes the table had a hole where the large bowl rested, which led to the making of dry sinks. From about 1820 to 1900 the dry sink evolved by the addition of a wooden cabinet with a trough built on the top, lined with zinc or lead.This is where the bowls or buckets for water were kept. Splashboards were sometimes added to the back wall, as well as shelves and drawers, the more elaborate designs usually placed in the kitchen.
