How to Install an Outdoor Sink Faucet

Build an Outdoor Sink (Part Two) – Connecting the Water Supply

So, I’ve already shared how I built my own DIY outdoor sink frame. Now, I will share how to install an outdoor sink faucet and make the connection between the faucet adapter on the stainless steel sink to the garden hose! It is such an easy set-up and I cannot help but be excited over the fact that having a DIY outdoor sink station is so convenient!

Having an outdoor sink that hooks to the hose is incredibly convenient, especially for filling pet water dishes, rinsing paint brushes, or even to get a drink of water!

I connected my outdoor hose to the sink for the water. A line can be connected to both the hot water handle and the cold water handle, though obviously there will be no hot water. In my setup, I only have one line running to the cold water handle. Eventually, I will connect a line to the hot water handle so that it won’t matter which handle I turn on – I will have water on either side! I connected a “Y” splitter on my spigot so that I could keep my regular garden hose connected to the water, then will eventually add another “Y” splitter to the leader hose to run the line to the hot water handle, as well.

Use teflon tape on the threaded (male) ends of the connections. This will make it easier to take them apart, especially if they corrode and also during the winter so the water lines don’t freeze.

Remove the compression nut and the brass ferrule from the straight connector. These parts will not be used. Apply teflon tape to the wider end of the connector.

 The straight connector will be attached to the brass hose connector.

Apply teflon tape to the narrow end of the straight connector then connect it to the narrow end of the faucet connector (water supply line).

The faucet connector will then be connected to the faucet while the other end will be connected to the leader hose, which is in turn connected to the “Y” splitter at the spigot.

For the drain, I will connect a “T”-shaped drain which is exactly the same one that is found under the kitchen sink. Installing the drain is pretty straight-forward. Check the installation instructions on the packaging. (At the time I took the photo, I hadn’t installed the drain because the compression nut was corroded – I had to wait for my dad to bring a wrench back to the house!) Then, I will use a bucket to catch the grey-water.

Eventually, I would like to dig a trench to lay a PVC drain that will flow into the drainage path at the front of our house then I won’t need the bucket anymore! For now, I’m liking the bucket!

Easy-peasy, right? I would like to thank the guys at my local Do It Best hardware store who helped me gather all of the parts to install the outdoor sink faucet! Have a question or two?

    This is a really inspired + inspiring idea. I’ve been wanting a mud room sink for awhile, but lack a mudroom. Why not put it in the backyard? Thanks for the tutorial, Cher!

    One thing you missed is the air gap. Their is no gap of air between the drain and the bucket, so dirty water could back flow into the sink. Fix this by cutting the drain pipe shorter, leaving a gap between the drain and top rim of bucket. The bucket will overflow instead of allowing water to back up into the sink. 😉

    • CherTexter says:

      Hi, Michaela! Thank you for taking the time to comment – comments are always appreciated! The drain connected to the sink in the photo was only temporary until the new drain was installed. Thanks for the tip!

  • Dockdog2 says:

    I have a question about the legs of the sink. You list all 2×4 material on your list but the pictures don’t look like 2×4’s. Did you rip them down? Of buy them? If so can you list what size they are?
    Thank you

    • CherTexter says:

      The legs can be cut from 2x4s or 2x2s. Since there is no cut list (except for the height of the legs) it doesn’t really matter. I used 2x2s for the sink base I built. Hope this helps! 🙂

  • Ron Thompson says:

    You can simplify by using a washing machine hose as It is female at both ends, so it eliminates the leader hose, and the brass hose connector. Just put the straight connector directly into the washing machine hose, then connect the faucet connector hose.

    Well done. Depending on the quality of your local water source you can add a under sink tankless water heater for ~ $100 – $150. Just finishing an outdoor kitchen section of a covered deck project, this is next on my list. I may add a basic filter to prolong life. Another option for what you have would be to add wheels, now you have a portable sink for anywhere you have a water source.

    • Bob says:

      BTW. You can get a 1 year level sediment filter for a misting fan to use before the water heater for $20.

    I’m in the process of building an outdoor bar. It has a regular 2-line faucet. I only have a cold water pvc pipe running to the bar. Is it possible to install an instant hot water dispenser to the hot side of the faucet to provide hot water? All the faucets I have seen for these dispensers have 3 lines. Thanks.
