Best Undermount Kitchen Sink 2019 Buying Guide

TYPES OF SINKS:

Before we start off with the factors that would influence your decision, let’s have a look at the types of undermount sinks available. While some of them have single bowls, some have double and triple bowls as well. The triple bowl sinks are not very popular and so we will avoid them from our list.

Single Basin Sinks:

This is the most popular under-mount sink and the most used variant. Hence, they are widely available in the market. The single basin sinks vary in their size and should be carefully chosen in accordance with the space available and the counter that you are using. They are easy to install and maintain and are cheaper compared to the double basin sinks of similar size. These sinks are ideally suited for small kitchens but it is difficult to clean large dishes or utensils in them once the sink is full.

Double Basin Sinks:

The double basin sinks or the sinks with two bowls are larger that the single basin sinks and are usually more expensive when compared to single basin sinks of similar size. The double basin sinks scores in the mere fact that the dirty utensils can be stored in a bowl and washed in the other. Generally the faucet is placed in the middle of the two bowls but the wall separating the bowls can pose a problem in limiting the movements when dealing with large pots. Though this problem can be tackled by fixing the faucet above one of these bowls. There are double basin sinks in which you have even bowl or same sized bowls while some others have asymmetrical or uneven sized bowls where one bowl is larger than the other and sometimes even shaped differently.

Round Basin Sinks:

These basin sinks are not very popular but will impress you enough with their looks and that’s the only advantage they have over other basin sinks. But you need a custom counter to install a round basin, as most counters have a rectangular cut-out space for the sink. Also a round sink on a counter top leads to space wastage.

Farmhouse Sinks:

Another very popular variant in recent times, farmhouse sinks come with an apron that bears the same finish as the sink. They look great and will accentuate your kitchen design while being very functional as well. They are deep and will provide you more clearance under the faucet so that you can clean or fill your large pots and pans easily and comfortably. The only disadvantage with these sinks is that the apron tends to get scratched over prolonged use.

SIZE:

 The size of the sink has already been mentioned while discussing single basin sinks. If you are just changing the basin sink in your kitchen, then you should go for the one that goes with available space in your counter-top design. But if you are remodeling your kitchen then you can either choose the sink and then order the counter-top accordingly or you can order a customized counter-top in accordance with your chosen sink. The availability of the space in your kitchen should also be kept in mind while deciding on the size of the sink. Choosing a double basin sink with two asymmetrical bowls can work wonders rather than choosing a single large basin that can take up more or equal space.

SINK MATERIALS:

The material with which the sink is made is an important factor that should be taken into account. The material not only influences the durability of the sink, but will also influence the maintenance required. The material should also go with your kitchen décor, though most sinks come in various colors and finishes that can be chosen according to the décor, once the material is decided upon. The heat resistance of the material is also very important as you are going to put hot vessels and utensils in the sink.

Stainless Steel:

The most popular material used for kitchen sinks, the stainless steel goes almost with every kitchen décor. The new stainless steel sinks come with rubber pads that absorb the vibrations that are produced when the sink is used. So you will not listen to those cluttering sounds any more. But the stainless steel sinks have their share of disadvantages too. They get scratched easily and so most modern stainless steel sinks come with bottom grids to avoid scratches. They cannot hide water stains and fingerprints and need regular maintenance to keep them spick and span. A wet or a dry cloth can do the trick. When choosing stainless steel sinks it is recommended to stick to ones of 18gauge and below to reduce the risk the dents and dings.

Granite:

The granite sinks are gaining in popularity recently and scoring over their stainless steel competitors. This is because the composite that they are made of, which comprises of a combination of acrylic and at least 80 % granite, is more durable, scratch proof and even fire proof. They are extremely durable and come in a wide array of colors that complement modern as well as classic kitchen interiors. Fingerprints or water stains do not make their marks easily and hence they need very low maintenance.

Composite:

Some sinks are made of a composite that combines acrylic with polyester resins, quartz or granite. They are much lighter than granite sinks but extremely durable, scratch resistant and comes in a variety of colors to go with your kitchen décor.

Copper:

Copper is a material that will not tarnish or rust over prolonged use and have all the essential qualities needed for a kitchen sink material. A green or brown film called patina will develop naturally that will give it a unique finish. You may or may not like it. Copper is durable and has antimicrobial properties which means that this sink will resist bacterial and viral growth.

Fireclay:

Though many may think that fireclay is not a suitable material for a kitchen sink, but this extremely durable material is chip and scratch resistant and won’t discolor or fade when exposed to water or chemicals. Today they are available in different colors to suit your décor and the non-porous surface is 100% resistant to bacteria.

Porcelain:

Porcelain again is a very durable and heat reisistant material ideal for kitchen sinks. Though the ones without any coating can well suffice your needs, but the high end ones are enamel coated to create a smooth scratch and stain resistant surface.

Cast Iron:

Cast iron is also a very durable material and a porcelain enamel coating enhances its durability. They are available in a large number of colors and have high heat resistance as well as sound deadening properties.

Now choosing the basin sink material will depend on the countertop that you have. For example, if you have a granite counter top, then a stainless steel basin sink would be the ideal choice.
