When my wife asked me to install an outdoor shower for the kids to use after being at the beach all day, I decided it would be a great opportunity to construct a solar shower. Here are the instructions.
- Locate an area that gets good exposure to the sun, especially around the hours you hope to use the shower.
- I won’t go through the steps for building the actual stall itself and will, instead focus on the plumbing.
- You will need to purchase:
- 100 feet of black high pressure garden hose (make sure it can handle high pressure and heat).
- Enough garden house to run from an outdoor faucet to the back of the shower. This does not need to be high pressure.
- A small section of garden hose, about 5 feet. This does not need to be high pressure and can be any color.
- A T connection (will connect one hose to 2).
- About 10 feet of ½” pex tubing
- Buy or rent a cramping tool.
- Brass connections for cramping tool to garden hose available at hardware stores. 3 pieces.
- Outdoor shower faucet with separate hot and cold connections.
- Run the garden house from your outdoor faucet to the back of the shower.
- Connect this garden house to the T. Connect the 5’ of garden house to one of the T-s and set aside.
- Connect the one of the other brass connections to the other T and then cramp a 5 foot piece of pex to the fitting. Connect the other side of the pex to your cold water connection and cramp in place.
- Build a 2 foot by 2 foot box using 2×4 frame and a plywood bottom. Coil the black hose inside the box and drill a hole for each side of the hose to poke out the bottom. Line the bottom of the box with insulating foil. You will later cover the box with a 2 foot by 2 foot piece of Plexiglas. The box will sit on top of your shower.
- From the other T, connect the 5 foot piece of garden hose and run it up to and connect it to your black garden house.
- Connect the other end of the black hose to the last cramp fitting. Cramp the other 5 feet of pex to this and run it to your hot water side of the faucet and cramp in place.
- Except for the construction of your shower you are done.
BE CAREFUL: The reason you need a cold water side is because the water will get incredibly hot.
