Tiny House Living: Water Usage

How Much Water Does a Tiny House Actually Use?

For this post we are going to take a deeper look into our Tiny House Water Usage. When we moved into our Tiny House In December 2014 we brought our old habits with us. Not to say these habits were bad but we were already adapting to living in a smaller space. we realized then we needed to make this drastic downsizing something sustainable so we can live in comfort and go about our daily lives as we would in a larger house.  One thing we noticed was even though our habits are still the same our energy and utility usage has dropped drastically. We are now more aware of what we are using and by using more efficient appliances and fixtures our energy usage and dependence has dropped significantly.

Appliances And How They Affect Our Tiny House Water Usage

Let us take a look at what we have on our tiny house that uses water. First we have our Kitchen Sink with Double Basins. We use this the most for cooking, washing dishes, filling up our Brita water filter etc

Next we our smaller Bathroom Sink from IKEA. During the design phase we knew we needed to have a separate sink in the bathroom and we are glad we stuck with that. It makes it so much more convenient to have a separate sink with two people living in the tiny house for bathroom duties.

Adjacent to our Bathroom sink we have our shower. With a On Demand Water Heater we can take as long of showers as we want with unlimited hot water (especially awesome in the winter).

Across from the shower and sink we have our Lg Ventless Washer Dryer Combo Which we use often. Every big house has a washer dryer combo so why not a Tiny House? During the warmer summer months we will line dry our clothes outside, but now that the temperatures have dropped into the 30’s and 40’s it is way too cold.  So use the condensation drying function on our LG Unit. The average water usage per cycle is about 20 gals.

How Do We Track Our Water Usage in Our Tiny House?

To further understand and track our Tiny House Water Usage we installed a Garden Hose Water Meter to monitor our usage going forward. I routed the water meter before the split tee that runs into the house so it will include water usage for the garden and washing the cars.

From the Water Meter it runs through our On The Go Portable Water Softener. (Enter “tinyhousebasics” to Save 40% off Any System) For more info on our water softener please visit How To Determine If You Have Hard Water from the water softener it runs through our rv filter the into the Tiny House

After closely monitoring our water usage for the past 3 months and without changing our habits at all, we use an average of only 35 Gallons Per Day! That sure is a far cry from the average household use.

According to the United States EPA :

“The average American family of four uses 400 gallons of water per day. On average, about 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!)” according to the United States EPA

Since we are a family of two our daily average of water usage in a larger house would be approx 200 gallons a day so our actual usage of only 35 Gallons a Day. Which is Only 17.5% of what the average household of our size would use and in a Drought Stricken state like california, every bit helps!

    We’re at about 20 gallons per day when we both take showers. I put in a recirculating shower so that we can each take a shower as long as we like for 5 gallons each. We cycle the water through a filter system and a tankless water heater. It then goes to water the trees around the house. http://dreamsbytheacre.blogspot.com

      Very cool! so you’re saying the water is filtered then recirculated to the same shower then purged after the shower is finished?

    Living on a boat it’s easy for me to calculate we go through about 75 gallons a week. This doesn’t include the 6 gallons of drinking water we get from the water store in our stainless steel container, or laundry we do on land. I’m happy with our conservative water usage.

    Hello, may i ask, where does the water come from? starting my tiny house planning and the only question that cant seem to be answered is where the water comes from? Do you have a hook up to a water supply? or do you have to manually fill you tanks daily? most tanks are 40 gallon so if youre using 35 gallons do you fill it daily? sounds like a hassle to fill a tank repeatedly. thank you!

    Stupid question but when you approached people and found a place for your tiny home, how do you actually hook up to their well and septic tank? Does someone come out and add the extra spicket?

      We actully trenched a water line and hooked up the water supply ourselves. and there was already septic connections for rvs right nearby our tiny home.

    Hey Joshua
    What is the white cartridge deal that is on your house…looks like the on the go system is hooked up to it prior to the water going into your house. Getting my water system set up and was told that the water has high iron content…Looks like the ON the go system will take care of that. Also, I’m in MN, do you know how these work in the winter and do they need to be inside to work properly? Thanks!

      Hi Sara, i just answered the last post with a few links, the on the go system works great in the winter out in california, you might want to reach out to them and see if they have any recomendations for the winters up in MN. i think at least a heated garden hose will do the trick to keep the water from freezing inside the softener

    Hi, I’m 19 and saving and doing as much research as I can before I pack up and start my tiny home journey. This information was very useful. I wanted to know if you could email me so I could ask a few questions.
