Showering outside or finding a shower while on a trip is not always an option, so we came up with an indoor shower idea for our Sprinter van. It is portable, collapsible, and rather inexpensive to build.
First, we started with the shower pan. It needed to take up little space when stored, but be big enough to catch the water when showering. We used a Kopeks Outdoor Swimming Pool Bathing Tub, sourced from Amazon. We bought the medium size, which is 32″x8″.
The drain that comes with the pool is located on the side, about an inch from the bottom. That wasn’t going to work for us so we bought a 1½” threaded bathtub drain and installed it at the bottom of the pan. This was very simple to do with a couple of careful slits with a sharp razor knife and then screwing the drain fitting onto the pool bottom using the seal that came with the drain kit. After the drain was installed we attached a 90 degree, 1½” barbed elbow and a section of braided, clear hose sourced from a local hardware store. We reduced the hose to 1″ with a reducer/coupler since a 1½” bulkhead drain would not fit where we would be installing it (the next step).
We located a spot in the side of the slider step area that would accept a double-threaded bulkhead fitting. This is where the water will drain to the outside of the van. I found a nice flat spot that was out of the way and drilled a hole using a hole saw. I figured this spot was great because if I ever needed to patch it back up, it would be very simple to access, weld in a plate, and cover it with trim or vinyl matting.
After the drain porthole was cut, I primed the edges with Rustoleum oil-based paint to prevent rust.
The bulkhead fitting fit nicely along with a 1″ PVC style elbow on the inside. It came white, but I spray painted it black to match. I also added a 1″ barbed elbow fitting outside to direct the water straight down. Originally we were worried the water would puddle up near the slider area of the van causing us to track mud in. We were going to add a section of hose and divert the shower drain water to the other side of the van, but it didn’t drain very fast. We found that the amount of water that drains out from a normal shower doesn’t even cause a problem near the slider door, therefore we just let it drain straight down from the fitting.
To keep the setup and teardown time to a minimum, we used cam-locking couplers to attach the hose to the drain port.
The couplers make it quick and clean to hook up and disconnect. We purchased caps to seal off the drain port and the hose from the shower pan to keep things dry and tidy.
Once the shower pan is all hooked up, we set a foldable bamboo shower floor inside and let the drain hang over the slider step area.
So I bet you’re wondering how the heck we keep all this shower water contained while showering right? Easy. We just hang up two shower curtains on magnetic hooks and squeeze clamps. The shower curtains with the weighted magnets keep it inside the shower pan, but a squeeze clamp is sometimes nice insurance to keep the floor dry. This literally only takes a few seconds to do.
For water supply, we use the Ambassador kitchen sink faucet. It pulls out 6 feet and has hot water thanks to a Bosch water heater and our plumbed-in waterpump. It even reaches outside the slider for hosing off your feet on a hot day. More on our water system here.
“We did it!”
We tested our portable shower a couple of times on a recent trip. It worked out great and the van floor never even got wet!
Some have asked us what we do about the wet shower curtains afterward. We just bunch the shower pan up in the corner and let them drip dry into the pan overnight. In the morning we fold everything up and hit the road.
Stowing away the shower pan is easy. We either shake out any excess water outdoors or wipe it down real quick with a towel before folding it back up. We stow it away in a rubber bin/ tote, along with the shower curtains and a bath rug, underneath our bed/ couch.
Don’t Forget to Be Earth Friendly!
Some soaps and shampoos are not good for the Earth.
So we use Dr.Bronner’s Peppermint Castile Soap when showering.
