How to Make Cheap Utility/Garage Sink?

With my setup, I also don't have it in an insulated building with heat (live in South Dakota). The plumbing consists of a hose attached the the frost free hydrant on the other side of the building. It goes up over the door, around the side and then hooks into a 4 way valve with shutoffs. One goes has a hose hooked to it and goes to the spray nozel. Makes a great pot filler, and gives me the spray pressure needed to blast veggies and butchered things clean.

The second vavle goes to the on-demand water heater. This is mounted so it's easy to take down and bring in the house for the winter. The third valve goes to the cold water side of the faucet in the laundry tub.

This system has a grey water drain, which is OK where I am. I have a septic system so try not to run any harsh stuff into in anyway.

Pinch-me, I have a four burner coil cooktop (under the cover the canner is sitting on). The lower height of the cooktop area is great for working with tall pots and the canners.

This is a picture of the cooktop before I cut the desk down and moved it to the center of the room.

I've been amazed at how great it is having this "out of house" work area. I'd encourage anyone in putting in a sink/work/cleanup area in a garage or shop. It's so nice not worrying about getting some peelings or drips on the floor while you are in the middle of things.

However I insist my husband use a bucket when he's bringing in something that might leave blood drips on the floor.

Stacyneil - could you install a frost free hydrant? The waterline is buried below the frost line and the actual shutoff is under ground also, so the hydrant itself never freezes (even when it about F out).

That is what I have in the shed - No Way would I be bringing in the animal water containers into the house to clean in the winter, and I have a utility sink in the laundry room too.


DIY Plumbing: Installing a utility sink in a garage

Adding a utility sink to your laundry room, garage, shed, or even your kitchen is a fairly easy way to make access to water a lot easier. The best part is that you can get all the pieces you need to put in a sink on your own pretty cheaply, assuming you already have water and drain access. Let’s take a look at a few things to look for.

Where Is Your Sink Going?

If this is a sink that is going to be in an unheated area, be sure to use insulated pipes. Freezing could cause the pipes to burst, leaving a mess. More often than not, however, you’re looking to add a utility sink in an area that doesn’t really ever drop below freezing, like your laundry room. Let’s take that as our example.

You should try to locate it in the room at or near an existing water and sewer line. If you do not, it can be quite expensive to add these pipes and this work does begin to stray away from the DIY space.

Once you’ve located your spot, measure how much space you have to work with and head to the home improvement store. You’ll need a few things:

  • The sink itself &#; Generally, utility sinks come separate from their bases. The sinks found in local home improvement stores are generally a highly durable plastic that fits atop a stand or vanity.
  • Stand or vanity &#; the sink isn’t going to hold itself up! Be sure to grab something that matches the look you’re going for. If your laundry room is tucked away and looks don’t matter so much, some simple legs will do the trick.
  • Faucet &#; Utility sinks don’t come with faucets &#; be sure to grab one that meets your needs and ensure that the sink and faucet have matching hole configurations.
  • Drain and valve parts &#; This will be highly dependent on the setup of your home, but you’ll want to ensure that there are valves to control the flow of water from the main water line to your faucet and enough pipe for drains to your waste line.
  • P-trap: Make sure you leave enough room for a p-trap. A p-trap is simply a piece of piped shaped like the letter which serves two main purposes. First, it always has water in it from your faucet, so it keeps sewer gases from flowing back out of your sink. Second, the trap makes a natural fall for any larger objects that fall down your drain like rings, rocks, or other items. It makes for easy clean out.
  • Be sure to consult YouTube, This Old House or any of a number of other videos for step-by-step instructions on how to install.

Once you have your parts, you’ll want to measure and fasten your pipe pieces, rough fitting them into place before you place the vanity and sink against the wall. Once everything looks solid, slide your vanity and sink into place and hook it up. You’re all set!

This may seem like a big job, but it doesn’t have to be. It’s even easier if the hookups and drains already exist. Simply unscrew and remove the current sink and replace it with a new one. As always, if you have questions or get stuck, it&#;s best to contact a licensed plumbing professional. Whether you&#;re located in Manteca or Mountain House,  Simpson Plumbing can help.

Can you put a Utility Sink in the Garage?

Whenever you work on anything in the garage, you are sure to get your hands dirty. It could be a paint job or just changing the tires. So how do you clean up without having to walk back into the house to your kitchen sink? Don’t you wish you could have a utility sink in your garage?

You can certainly install a utility sink in your garage. It is a relatively simple DIY project if you have some experience in plumbing. You also have the option of using a portable sink that does not require any plumbing.

Once you put a utility sink in your garage, you will be amazed at the number of ways you are able to use it.

Why have a Utility Sink in your Garage?

The utility sink in your garage will let you clean up before entering the house. The obvious benefit is your house remains clean. 

Here is a list of a few occasions when you will find the utility garage sink really handy.

  • Fixing a few things on your car? Get your hands all clean before entering the house.
  • Mopping your garage floor to make it look clean & new? Clean the mop in the sink after you are done.
  • Been doing some outdoor gardening or like to grow vegetables in the garage? Clean up the rakes and the shovels before storing them.
  • Took the dogs out for a walk? Give them a shower in the garage utility sink so they don’t muck up the house.
  • Had a little party in the garage? Clean up the dishes in the garage utility sink.
  • Your kids have been doing their arts project in the garage? Clean them and their paint brushes in the utility sink in the garage.

Honestly, once you have a utility sink in the garage, you will wonder how you managed without one all this time.

What Type of Utility Sink do I Need?

Yes, that is the first and possibly the most important question that you need to ask. Obviously the type you need depends on what you are going to use it for, most of the time.

Sink Dimensions

You do not need a large utility sink if the purpose is just to get your hands clean before you enter the house. A small hand washing sink will serve your needs pretty well. The sink dimensions in this case could be as small as 12″(L) X 12″(W) X 6″(D).

Stainless Steel Hand Sink with Side Splash – NSF – Commercial Equipment 12″ X 12″ from Amazon is an excellent example of a compact hand wash sink suitable for garage use.

On the other hand if you are going to be using your garage utility sink for giving your dogs a wash or for cleaning the garden rake, then you need something considerably bigger. Go as big as 40″(L) X 24″(W) X 14″(D).

Mustee 28F Bigtub Utilatub Laundry Tub Floor Mount, Inch x Inch, White from Amazon is large enough to meet your requirement of a big garage utility sink. You will find many uses for it.

Sink Material

When choosing the material of the sink, keep in mind that you want something that is

  • Rust Proof
  • Corrosion Resistant
  • Stain & Scratch Resistant
  • Unbreakable
  • Lightweight

Impact Resistant Polypropylene will tick all the boxes and yet be easy on the pocket. Stainless Steel is a great option, but a lot pricier. Porcelain used to be popular (and still is when it comes to bathroom fixtures), but quite unnecessary in the garage, in my opinion.

Faucet Type

Quite often the sink does not come with the faucet, which is a good thing. When it comes to faucets, everyone has their own special needs and preferences. So it is best to buy it separately and install it

Some options that you can look at are:

If you are using the utility sink in the garage for more than just washing your hands, then you need to give special attention to the Spout and the Sprayer. 

Spouts can swivel and Sprayers can have a longer hose length. You also want more than one option on the spray type and the spray pressure. 

That way you have more flexibility. You could easily switch from a hard spray to remove dried out mud from shoes to a gentle rinsing off of soap from your pet pooch.

How do I Install the Water Pipes to the Sink?

Not all garages are the same. I am sure your garage is a bit unique in its own way.

Laundry Room in Garage

Some homeowners have chosen to have their laundry room either in the garage or adjoining the garage. This idea is not without its merits. 

Should you be considering this thought then check out my blog post How to Make an Enclosed Laundry Room in a Garagefor some ideas. You may then add the utility sink in the laundry room in the garage, alongside the washer. This would be killing two birds with one stone.

Mudroom in Garage

Other homeowners, almost always, use the garage entry door to the house rather than the front door. So much so that they have set up a mudroom right there in their garage. 

What do you think? Were you to do this, you would have no need for a separate utility sink. Just incorporate it in the mudroom in the garage. Not convinced? Why not check out my post Why Add Mudroom Entry From The Garage? 7 Really Great Reasons.


It’s alright if the above two ideas won’t work for you. No worries! You can still install water lines to the sink. It would be helpful if the location of the sink is such that it is near

  • The wall adjoining the house
  • The garage entry door to the house
  • A kitchen, laundry room, mudroom or bathroom that has water supply
  • A drain


If you are not too sure of your DIY skills in the plumbing area, then get a good plumber to do it for you. It will cost some, but, trust me, the results will be worth it!

But if you want to do it yourself, that’s great too. It’s not too difficult when you have some skills, the right tools and the required supplies.

The Process

Start off by making sure that the main water line is shut off before you start any plumbing work. Also open all the taps so that all remaining water in the house pipes is drained. You do not want your house flooded.

You need to tap into the existing cold and hot water lines in the house by installing a T joint. Here it is important to install a ball valve on the section leading out to the garage.

This way you can shut off the water supply to the utility sink in the garage from within the house.

Run the PEX water pipes from within the house to the garage through a hole in the drywall.  The pipes should be run to a point close to where you intend to locate the sink. 

At this point the PEX pipe should be joined with copper tubing which then connects to the sink faucet. The hot water and cold water tubes should have control valves to control the water flow.

As a safety measure, fit check valves at the joints. The check valves are one-way valves. Water will always flow from the house to the sink and never the other way around.

It is also a good idea to screw on large, clear or white plastic sheets on the garage wall behind the utility sink. That way your drywall will never get wet from water splashes from the utility sink.

Will the Water Lines of the Garage Utility Sink Freeze in Winter?

Yes they will if your garage is not climate controlled and the garage temperature drops to below freezing.

You really have 3 options:

  1. Climate Control your Garage. I know you are not going to spend a ton of money just to protect the plumbing of the garage sink. But a climate controlled garage has a host of benefits. Free flowing water in the garage utility sink just happens to be another one of them. Get full details by reading my post How To Make Sure Of Best Climate Control For Your Garage.
  2. Insulating the cold water pipeline.
  3. Switching off the water supply when the outside temperature dips below freezing.

How to Set up the Drain for the Garage Utility Sink?

This is a rather simple job as you can get all the supplies from Home Depot or any other hardware store.

You need a Tailpiece that attaches to the utility sink drain hole. Most importantly you need a P-Trap. This comes as a Kit. The function of the P-Trap is to ensure that smelly sewer gasses do not waft into your garage. 

In a way it’s like a one-way valve. Drain water can go to the sewer but sewer gasses can’t come back in.

All you need to do is connect the Tailpiece to the P-Trap using a Tailpiece Extension and connect the end of the P-Trap to the pipe leading to the drain.

All plumbing is PVC so if any cutting is required that is quite easy. Be sure to use PVC Cement and Teflon Tape on the threads to ensure all joints are sealed and there won’t be any leakage or dripping.

Can I Install a Garage Sink Without Plumbing?

What if you do not want to go through all this trouble, but you still want a sink in the garage? At least to wash your grimy hands after being on the workshop bench for a while.

In that case you can buy one of the portable sinks from Amazon.

If you want both hot & cold water then Portable Sink Self Contained Hand Wash Station with Cold and Hot Water made by Florida Portable Sinks is a great option!

  • No water installation or drain hose required. Only plug into a v outlet and fill the fresh water tank.
  • Stainless steel NFS approved sink, high quality and durable. Cabinet is made out of injection molded polypropylene that is: Germ-resistant, Maintenance free, Will not warp, Will not rust and Will not dent
  • The sink is equipped with a quality water pump, a FLOJET BW Bottled Water System. The water heater is an EEMAX Mini Tank Electric Water Heater with a thermostat to adjust temperature range (50°F to °F).

Thank you very much for reading the post. I do hope you found it informative and useful.

How To Install a Utility Sink

Remove Burrs From the Pipes

Remove any burrs off the end of your stub pipes using the reamer on the end of your pipe cutter. Take a 3/4" double compression fitting and slide one nut and ferrel onto your extension pipe. Tighten down the connection to the center compression coupling.

Attach the Soft Tubing

Repeat the steps for the other stub pipe, sliding on the nut and ferrel. Then, tighten it to the compression creating a watertight seal. Attach the soft tubing to the compression coupling by sliding one end of the tubing into the coupling, then tightening it down at first by hand. Tighten with a wrench while backing off with another.

Run Tubing Across the Wall

Slowly run the copper tubing across the wall, then to the sink. Repeat this process for the other water line. Don't overbend the pipe or it will crimp and cause a leak.

Secure Pipes to the Wall

Use 1/2" copper clips to secure the pipes to the wall. Simply place the clip over the pipe, then screw them in with screws and shields. The LAV stop connects the same way as the water lines. Tighten down the compression fitting to make the seal. Run the hot water line to the left and the cold on the right to match the faucet.

Apply the Sealant

Apply a line of silicon sealant around the edge of the opening. This will hold the sink into place and create a watertight seal.

Insert the Spaces

Place small blocks of wood around the corners of the sink opening. The blocks serve as spacers, keeping your fingers from getting pinched between the sink and the workbench. Finally, put the sink and faucet into place.

Coat the Male Adapter

Coat the thread of the male adapter with Teflon paste, then firmly tighten it into the old cleanout threads. Glue in a new Y fitting with a cleanout. On the open end of the Y fitting, run your drain line out to the sink area. Make sure to keep a constant pitch for drainage. Connect the water lines from the faucet to the water pipes.

Apply the Plumber's Putty to the Flange

Apply some plumber's putty around the bottom of the flange. Place the strainer in the hole. Attach the rubber washer, fiber washer and locking ring to the underside of the strainer and tighten.

Glue the Female Adapter to the Y Fitting

Coat the threads of the auto-vent with Teflon tape and hand tighten into the female adapter. Glue the female adaptor to the middle hole of the Y fitting.

Attach the T-Y Fittings to the Drain Line

Glue the T-Y fittings with the vent onto the drain line. Ensure the direction of the bend goes toward the drain line. Attach the tailpiece to the sink strainer.

Connect the P Trap to the Tailpiece

Connect the P trap with the trap adapter to the tailpiece. The final piece of the P trap is a Street that connects the trap assembly into the open end of the vent T-Y fitting.
