💁Determine the sink location

As a rule of thumb, your location to install your utility sink must have both hot and cold water supply and a stable drainage pipe. Once you have decided where you want to place the utility sink, close the water supply from the primary water valve.

💁Mark the pipe

To simplify the process, put markings on the drain pipe and the hot/cold water pipes. These markings will show where the fittings will go. You can then cut accordingly. 

Install a “Y” shaped fitting in the drain pipe and a “T” shaped fitting in the water supply pipe. These fitting will allow the water to flow to the faucet directly from your home plumbing and ensure proper drainage.

💁Establish hookups

You need to create hookups for drain pipes and water pipes separately. 

Drain pipes

Since these pipes are most often made from PVC, they are easier to work with than water pipes. You only need a handsaw to cut the drain pipes. You need the hookup to attach the “Y” fitting. Once connected, apply a small layer of primer and glue to the end section of the fitting and place it in the hookup. Once done, attach the PVC trap to the “Y” fittings. This will make way for the water flow.

Water pipes

Unlike drain pipe services, water pipes are made from copper, and you need a tube cutter to cut them. Once you create the hookup using a soldering torch, add it between the copper pipe and the “T-shaped” fitting. Now the hot and cold water supply will merge and flow from a single faucet.

💁Sink placement

Use a compression nut to place the sink under the newly established PVC trap set earlier. It’s advisable to use a generous amount of Plumber’s putty under the faucet before you fix the sink. You need to install flexible hoses to the faucet’s bottom to allow hot and cold water to flow smoothly.

💁Connecting it all

You can connect the flexible hoses to the “T” shaped fittings at this stage. Attach the opposite end to the hot and cold fitting. Once you are sure that all connections are established, turn on the primary water supply and check the working of the sink. Look out for any water leaks or any signs of loose connections. If you have set everything up correctly, the water should flow smoothly without a glitch.

What is the cost of installing a utility sink in the garage?

The primary cost will probably be the price of the sink itself. Additionally, if you hire a plumber, you will have to bear installation fees. 

However, homeowners often use their basic plumbing knowledge to install the sink themselves, which is a cost-saving option. The only thing is to understand and plan the project in advance. 

Is it possible to set up a utility sink without any plumbing?

Yes, it’s possible. However, they are special portable sinks, and if you want to avoid the whole plumbing thing, you will have to purchase one of these. 

Though many people opt for portable sinks, it has drawbacks. For instance, these are not as sturdy or reliable as plumbed-in sinks.

Can you drain your utility sink in the ground?

This depends on where you live. The regulations vary from one area to another, so check out the rules in your neighborhood regarding draining the sink in the ground. If you already have such a drain in your garage, you can empty your sink in it.

As a rule of thumb, the garage utility sink must be tough and scratch-resistant. Overall, you should not be worried about it getting damaged. Thus it’s essential to consider the material of the sinks and the faucet. If they have cabinetry attached, make sure it is scratch resistant as well. 

Stainless steel is the most popular material used in the construction of tubs and basins since they are scratch-resistant. 

💁Type of faucet

To pick the ideal faucet, think about the different ways you will be using the sink. For instance, if you plan to bathe your dog there, you will require a bigger faucet. You need a lot of clearance under the high-arc faucet as well. Make sure you have a high-arc faucet if you plan to put larger things under the sink. 


If you are required to fill the basin with water, stability is crucial. Ideally, the basin legs should be solid and made from stainless steel, so there is no risk of warping or buckling. 


Though many people opt for the DIY installation of utility sinks, you should hire a plumber if you can’t do it. Since it’s a simple and relatively easy job, the price should not be very high.
