How to Choose the Best Outdoor Kitchen Sink

Undermount versus Drop-in

You will see these two basic types of sinks that refer to how they are installed. With a drop-in sink, you get a wider rim that will extend out of  the counter and is exposed. A drop-in sink is easier to clean and install as well as cheaper.

In comparison, under-mount sinks have the same appearance as a drop-in sink, but the rim will sit under the countertop. Since the rim is hidden, you will only see the faucet and the bowl. This type of sink needs to be installed by a professional, and this more expensive sink is harder to clean as well since its rim is under the counter.


Typically, you will either see ceramic or stainless-steel sinks. The standard for home-use is 304 stainless steel, which won’t rust and is pretty durable. It’s a great choice for outdoor kitchen sinks.

Ceramic is a better choice for bathrooms since ceramic isn’t as durable and doesn’t need to handle stains. While they look nice, keep in mind that they can’t handle bleach or abrasive powders.


When considering a sink, the depth and size are super important. Always make sure to measure the space under your counter and include the height, length, and depth. Typically, most sinks will already tell you how much area you will need under your counter.

Deep and shallow are the two categories for the depth of an outdoor sink. Shallow is only about five to six inches deep and is only recommended if you will be washing just a couple of dishes. In comparison, a deep sink has a depth of 9 to 12-inches and can handle more cleaning and a lot more dishes.

Single-bowl vs. Double-bowl Sinks

A big impact on preparation and cleaning time depends on how many bowls you have in your sink. With a double-bowl sink, you prepare food faster and wash dishes quicker since you can soap them up in one sink and rinse them off in the other.

With a single-bowl sink, you get a larger capacity and more counter space. This type of sink leaves more area for your countertop and can typically hold more dishes.

Durability and Stability

A stainless-steel sink is made from 304 stainless steel making them corrosion and rust-resistant. They are safe to use bleach and harsh chemicals in without damaging the sink. In comparison, a porcelain sink isn’t as durably and can be shattered, so you have to be very careful with them during installation.

Water source

You can connect an outdoor sink to a water line or outdoor spigot. If you do not have water lines or pipes that can reach your outdoor sink in a preferred location, you can always contact a plumber to extend the pipes or water lines, or you can choose an outdoor sink design that allows you to connect to a garden hose spigot.


Typically, outdoor sinks will drain into your home’s plumbing system, or even through a hose that can drain into a bucket under the sink or into your landscape. Draining the outdoor sink into your home’s plumbing system is multi-functional since it won’t require having to be emptied, plus you won’t have to wash any landscape-safe materials with biodegradable soap. If you do not have drainage pipes that are located near the outdoor sink, you can always choose from the other two drainage options.

What is an Outdoor Sink?

An outdoor sink can either be used as a food prep area near your barbeque or as a utility sink to help you with large cleaning tasks in your patio or garden. You can use an outdoor sink to wash your hands, wash utensils, and even prep food.

You can purchase an outdoor sink in various styles, materials, designs, and widths. Depending on their size, you can use them to clean a wide range of tools or plates, pots, and pans.

Why You Should Have an Outdoor Sink?

If you are considering building an outdoor kitchen, having a sink is an important part of it. While some people are fine with cleaning fish in a kitchen sink, others find that a disgusting process to do in the house. Having an outdoor sink can help with these types of tasks, which can also help with the smell that goes with it.

If you entertain outside, it can be handy to have an area to retrieve water, clean off barbeque utensils, or even clean up after a meal. You can also use it for drinks and cleaning out glasses when you entertain.

Outdoor Kitchen Sink Mounting

If you don’t have an exterior wall that you can install the sink on, it can get expensive when you have to run supply lines to the sink. For those that don’t need hot water, you can save money by only running cold water to the outdoor sink. If you do want hot water, you can either run a line or use an on-demand water heat to give you hot water instantly.

For those in colder climates, you can also include installation that has an easy way to drain the lines and shut of the water to stop pipes from bursting and freezing. If you are using the sink for garden and yard use, it can be easier to supply water to it with a portable unit that uses a hose connection for drainage and supplying water.

Drainage, on the other hand, can be some of the most aggravating parts of this process. When you use an outdoor sink, drainage can depend on the type of sewer or septic system that you have and local laws.


1. What size should my outdoor kitchen sink be?

As you design your outdoor kitchen, consider what you will use the sink to help you determine what the overall dimension you will need for your sink. There are several types to choose from depending on your needs.

The smallest of the sink styles, a bar sink usually only needs between 12 and 16 inches of counter space width. These are great sinks to have for small jobs or entertaining, and they allow you to save the most space for your outdoor kitchen countertop.

A single basic sink is larger than a bar sink and typically measures between 17 and 26 inches wide and deep. With a double basin sink, you need between 30 and 36-inches of width and the depths of the basin can vary. Typically, you choose between a single and double basin based more on preference, usability, space, and functionality.

2. Which material is best?

By far, stainless steel is the most available and popular choice among the different materials that are offered. Always look for a sink that is made of 304-grade stainless steel since it is the most durable grade of stainless steel and gives you the best corrosion resistance. This is vital when ensuring that your sink will be able to withstand the elements outside.

The thickness or gauge of the steel is also important to think about. Remember that the lower the steel gauge, the thicker the steel is. With thick gauges, you get a quieter and more durable product that also has better resistance to any heavy objects that are placed in the sink. When you compare it to thin gauge steel, you will notice that the sink can dip if a heavy object is placed in it and you will get a plinking sound.

3. Should you buy a separate faucet?

Typically, a good quality outdoor kitchen sink will be sold separately, which means a faucet is not included. You can find some sink “kits” that will include a faucet, but they are normally made with inferior materials. First, find a standalone sink that you like and then choose a stainless-steel faucet that has a mixing valve as well as cold and hot hookups to complete your sink. That way you will end up with a higher quality end product as well as more choices when it comes to both the sink and faucet designs.

4. What about water hookups?

Typically, a sink will relying on both cold and hot water when it comes to adjusting water temperature. In comparison, an outdoor kitchen usually only uses a cold-water connection from a repurposed hose outlet or dedicated water source. And, when you choose a faucet, always make sure you have the correct connections.

If you are looking for a low-cost outdoor kitchen sink solution, you only need to hook it up to a cold-water line. For those that do want a faucet with both cold and hot water, you can also choose to only hook up the cold one for actual use.

This sink is also hygienic and provides antibacterial protection, which is great for those that want to use it for drinks or food prep.
