Undermount Kitchen Sink Buying Guide

You would think buying a sink was pretty straightforward – however, you’ll soon realise that a lot of thought needs to go into it before making a purchase. With all sinks looking reasonably similar in style and functionality, there are some key factors to consider before buying.

Pros of buying an undermount sink:

  • The main pro to purchasing an undermount sink is that due to its lack of sink edges, it remains cleaner for longer – there are no edges for dirt and food debris to get caught under
  • Undermount sinks give you more kitchen counter space – leaving you lots of room for cooking or those dirty dishes…
  • You will be able to brush debris, food, and dirt right into the sink without it getting trapped
  • Various options, designs, colours, and materials give you an extensive range of options for a modern and clean kitchen feature

Size & Design

You can purchase an undermount sink in a variety of materials, including; stainless steel, Quartz, cast iron, copper, ceramic & graphite, to name a few. In addition, they come in a range of sizes to suit different countertop materials and boast various features to suit your kitchen’s aesthetic. Unfortunately, however, a lot of these undermount sinks do look the same – which can make it quite confusing when trying to find the right one for you.

There are also various undermount sinks, including a farmhouse apron, standard single sink, double sink, wall-mount sink, and a drop-in sink.

Size

The first thing to consider before buying your sink is what size you need. The last thing you want to do is to go ahead and buy a sink and find that it doesn’t fit when it arrives! You need to plan ahead and figure out where you want to install it. Is it replacing an old sink? Or are you going to create a new space for the feature?

Measure out your chosen area and make sure you buy the right size, then you can start to choose your new sink based on aesthetic and function!

You can also consider other kitchen sink shapes – nothing says modern like an oval or angled sink. You can also purchase round, square, and standard rectangular sinks. Think about all the kitchen space you are going to get back!

Single or double?

Before choosing the material, you need to decide first about functionality. You can opt for two types of sink: a double bowl sink or a single bowl sink. Washing dishes has never been more straightforward with double bowl sinks. You can wash up in one bowl and soak in the other – seamless! Just remember that a double sink may take up more space on your counter, so you’ll have to factor that in when considering the size.

A single bowl sink resembles the traditional sink in most homes. The key difference is that a single bowl kitchen sink is generally deeper, allowing it to hold larger pots and pans as well as look tactful in your kitchen.

Stainless Steel Sinks

A stainless steel kitchen sink is the most classic option you can go with. This traditional stainless steel sink offers a simple look for your kitchen and is a dominant feature in homes across the globe.

Stainless steel kitchen sinks are generally the most popular due to steel being extremely durable and cost-effective. Choosing a stainless steel kitchen sink is the best option if you have little ones running about the house, as the material won’t chip or scratch easily.

The great thing about a stainless steel kitchen sink is that it will match your appliances regardless of colour, meaning you save the hassle of having to replace your appliances alongside your sink.

Quartz Sinks

Choosing a sink made of Quartz will make for an elegant and clean finish to your kitchen. Quartz is fairly similar to granite and is extremely low maintenance. Easy to clean and keep clean! It boasts all the best qualities you need in a sink, including noise resistance and heat protection.

However, Quartz can be damaged if you drop heavy pots and pans on it, so be careful with your more durable dishes. Quartz is slightly more affordable than the Granite option but still looks and feels professional.

Granite

Granite sinks are great because they will truly last a lifetime. GIn addition, granite is an extremely reliable and durable material – and doesn’t have to compromise on the look and feel because of it.

Granite is highly heat resistant; however, you need to be careful of chipping this material – so extra protection and a seal should be considered.

Installation of a granite sink can be slightly more tricky due to its size and weight. You also have to bear in mind if you are pairing with a granite worktop, you will most likely have to use a contractor to ensure this is installed correctly.

Heat Resistance

You obviously want to choose a sink material that is heat resistant. This means there are certain materials you should avoid, for example, a ceramic or porcelain sink, which don’t offer the best in terms of protection.

Quartz and granite are renowned for their ability to handle the heat – so bear this in mind when choosing the right sink for your kitchen.

Gauge Thickness

Gauge thickness refers to how thick the material is in your sink. This works because the gauge number represents the thicker the material, and the higher the gauge thickness, the thinner the material.

Keep an eye out for the product descriptions. Sinks will have a gauge thickness anywhere between 10 – 24. The thicker the sink’s material, the more reliable and durable, lasting longer with less wear and tear!

Sound Insulation

Generally, the sink will be noisier if the gauge thickness is higher, meaning the material is thinner. Certain materials also sound louder than others, for example, stainless steel.

Most undermount kitchen sinks come with a variety of sound and noise reduction options so that a late-night glass of water doesn’t have to wake anyone up! You can also buy additional materials like padding to place inside your sink to reduce the noise.

Installation

Instead of installing a sink in a pre-cut area of your worktop, an undermount sink is placed underneath the counter. This completely eradicates the rim around the sink on a classic fitting. It is recommended that you use a contractor to fit your sink. However, some of them are easy enough to install at home yourself.

Before having your sink installed, it is best to consult a plumber or contractor, even if you plan on installing it yourself, so that you ensure a top-quality installation.

How to Measure for Installation

It will be your countertop that will determine how large or small your sink needs to be and how much space you will have to fill. The interior width and depth of the hole in your countertop will determine the measurements of your sink. So obviously, to measure, you will need to remove the old sink first. This is only the case if you are using that space and not creating a new one.

Once you have removed your old sink, you need to measure the distance between the back of your sink to the front. The average sink will measure around 22 inches by 30 inches; however, each home will vary.

Price and Warranty

You’ll have to check each individual product for its own price & warranty – however, make sure this is something you look out for before making your purchase.

Most sinks will come with a limited lifetime warranty. Pricing can range anywhere from low market sinks at $200 to stunning copper sinks ranging up to $900.

If you have a granite countertop, you can face certain risks installing it yourself, including damaging the worktop.

Undermount kitchen sinks FAQs:

What is the main difference between undermount sinks and a top mount sink?

A traditional top mount sink is placed in from above, meaning it overlaps over the top of your counter. This is the classic style sink you see in most homes today. However, a seam around the sink will mean dirt and debris can be trapped – yes, those pesky coffee granules! An undermount sink eradicates this seam, offering a smooth transition between the countertop and the kitchen sink.

Can I use an undermount sink with all types of countertops?

Yes! You can pair your new sink with any countertop, including laminate countertops, quartz countertops, and granite. However, it is important to remember that the installation and size may vary depending on your countertop.

What should I avoid when cleaning my sink?

This can ultimately depend on the material. IFor example, if you have a steel sink, it is essential to make sure that you don’t allow scourers, clothes, or sponges to dry in the sink as they may leave a mark, stain, or rust.

Dish soap and water is generally the best way to clean your sink regardless of the material – avoid using abrasive cleaners like bleach. Baking soda, water, and vinegar are great to get the marks off a stainless steel sink. For other materials, use vinegar and water to disinfect. Soap and warm water to clean. See specific product details for more information.
