How Does A Tiny House Get Water?

How To Get Water In A Tiny House

Assuming you have a water source, which we will get to in a minute, there are two main ways to connect water into your tiny home. I’ve used both over the years and which you should go with depends on how often you’re going to move your tiny house.

This is where I started with my tiny house because it was very easy, used parts you can buy right off the shelf for cheap, and didn’t require a lot of technical plumbing. It’s also what I suggest if you move your tiny home often.


  • Simple to hook up
  • Works at most campgrounds
  • Quick to connect and disconnect
  • Good on mobile tiny houses


  • More prone to freezing
  • Slightly more expensive
  • Leaky hose connections common
  • Can snag hose and damage inlet


With this approach, you’re going to want to plumb your house like you would normally. The main water inlet entry point will terminate to the outside of your tiny house with a Shurflo RV water inlet. This will let you connect any water hose to your house easily.

One very important thing to consider is the hose you make this connection with. In the house, you’re going to want to use all PEX tubing, but from the house to your water source, you want to use a drink-safe garden hose that’s designed for RVs. This is because regular hoses have nasty chemicals which can lead to serious health issues, plus drink-safe hoses are only a few dollars more, so it’s well worth the money.

If you’re setting up land for your own tiny home, you most likely will need to install the other side of that drink-safe water hose, too. A frost-proof water hydrant will let you shut the water off when you’re not connected, and this style hose bib has a valve at the bottom of the pipe that goes into the ground. Since that valve shuts water off at the bottom, it’s below the frost line, meaning you don’t have to worry about it freezing.

Make A Permanent Water Connection With Your Tiny House

Make A Permanent Water Connection With Your Tiny House

This is currently what I do with my tiny house water connection and have been very happy with it. Since I haven’t moved my home in over eight years, it’s worked out really well, but it’s not practical for people frequently on the move.


  • Less prone to freezing
  • Looks neater on outside
  • Cheapest method
  • Lasts long term


  • Not meant to be moved
  • Needs to be cut if you do move
  • Requires you to bury water line
  • More technical skill required

I decided to go with this over the above method because a couple of times a year, my drink-safe water hose would freeze, leaving me without water. While that Camco hose never split from freezing which is a big testament to its quality, it was still pretty rough on the components involved.

Also, the frost-proof hydrant ended up rusting over time despite it being galvanized. I think they’re made to be used temporarily instead of constantly left on That’s why I recommend the in line water filter.

With this method, you’ll make a hard line PEX connection from your house to the ground and down to the main water line. Try to keep the gap between the house and the ground where the PEX spans as short as possible and insulate it heavily. I’d also suggest installing a 1/4 turn shut off valve there to cut water off to your tiny house should you ever need to.

Living In A Tiny House Without Water

Living In A Tiny House Without Water

When I built my tiny house years ago, a water connection was a must have for me, and I know I’m not alone in that. Having a readily available source of water that you can tap into and bring into your tiny home is essential. I’ve had a few friends who live in tiny houses that attempted living by only trucking in water and not one of them lasted a year.

“I didn’t put plumbing in my house because my land didn’t have running water, and so I knew I would be hauling water. Had I known what I know now, I would have put in running water—it would’ve made my life so much easier. That’s the one thing I don’t like about [my tiny house], and it has nothing to do with the size. I have drinking water in the bathroom, but if I needed to take a shower I would have to go to the gym and that was always kind of a pain.”

How Much Water Does A Tiny House Use?

How Much Water Does A Tiny House Use

I was surprised at how well low-flow shower heads and sink faucets work for me. At first, I was worried about the water stream being too weak, but after using them for years now, I find it to be more than adequate and never leaves me wanting more.

The average American uses around 100 gallons of water per day. After living in my tiny house for years, I’ve averaged out to around 11 gallons per day. That’s for one guy who hand washes his dishes and takes a shower every day.

Your Turn!

  • How do you plan to connect your tiny house to water?
  1. I’d add one thing no matter the type you choose. Have a shut off valve INSIDE the home that is accessible.
    Just like the electric, you never know when you will need to shut off everything completely.

    Thank you for pointing out the insulation. That is important also.
    You could use a waterproof foam on it and extending below ground.
    Even a spray on foam is better than nothing.

    Just like my home has a shut off inside and at the meter, the tiny house will have that also.

  2. Awesome content! Thanks

  3. A very helpful website, thanks. I’m on my second TH build now. The first being a Covid lockdown experiment, built on concrete piers in a permanent location with mains connection and it’s own septic… I hate the idea of composting toilets, so expensive too for what they are. Frost proofing water lines was my major problem with frost line of 4’ down. I made the mistake of putting some pex pipes within studwork with only R14 insulation. I closed the TH down for winter and blew out all water with air compressor to be safe. TH2 will be a different proposition, being based on an 18’ all aluminium flatbed trailer. Shell is built to accommodate R24 walls & floor and R32 roof… but frost on the incoming water supply is still my main concern. Good to see that you have experienced most if not all the possible options. I totally agree with your choice of separate structures for solar panels too. Very smart.
