Under-dinette Shower

Small tent trailers don’t come with showers. On extended trips where there are no public facilities the lack of a shower is less than inconvenient. Over the years I used a solar shower system with an outdoor shower enclosure. Setting up and taking done this shower was a lot of work and I needed to park the camper close to a large tree, and hoist a heavy solar shower (5 gallons of water is approximately 50 pounds) using a pulley system I devised. To say the least, this was a lot of work every day. But it did the job.

In 2003 I decided to tackle this problem and come up with a better solution. One possibility was a portable heated shower system. Both Coleman and Zodi made such systems. They still were quite a bit of work to set up and use daily, plus I would still need some sort of an outdoor shower enclosure.

Over at popupexplorer.com my friends Bill (Oz & Us) and Bart (EveryBodyHauls) had both installed portable shower systems inside their tent trailers using a plastic laundry room sink. But the problem with both was that these were still portable systems. The laundry sink, which served as the shower pan, had to be set-up and then taken down after each use; because the shower was set up in the middle of their campers. After a couple of months of exploring solutions, I finally came up with a solution that would work in our small camper. Soon Bill and Bart would convert their portable systems to a permanent installation based on my design.

Under Dinette Shower System

I decided that building a permanent shower under a dinette seat would the installation of fixed drain, could be set-up and left up during the camping trip while still having access to the seat when the shower was not in use, and would take little storage space. Since I was already rebuilding the camper from scratch, I had more options than someone who would try and do the same with an existing dinette. But both Bill and Bart were able to easily replicate the shower.

Since my trailer did not come with the plumbing to support a shower, I had to install a water supply system first. See my Water Supply System.


A standard laundry tub is 30″ X 30″ square, which is the same dimension as a simple shower. So it makes a perfect shower pan. Plus, the tall sides make it perfect for storing stuff when in travel mode.

06 Sink Drain

Water Supply

I decided to use the sink to supply water to shower, instead of hard plumbing the shower to the water system. This works well. But if I were to do it again, I would probably install a faucet inside the tub.

To use the shower, we turn on the sink and adjust the water temperature. Then we connect the hose for the shower head to the fitting on the end of the faucet.

Shower Curtain Version 1

What I really wanted to use was a track system mounted to the roof similar to those used in hospitals or large tent trailers. However I was unable to locate one. I devised a system using PCV pipe, which had to be assembled on each camping trip. This is because I wanted the shower curtain frame to be larger than the tub, so we would have ample room to shower. It really didn’t take long to set it up, but later I improved upon this design.

16 Shower Components

Above: All the components for the shower curtain rod, privacy curtain rod, shower plumbing, and rack to hold shampoo, soap, etc.

To suspend the shower curtain rod, I bought some nylon webbing, and used snaps on the ends so the I could connect the ends of the straps to form loops that would hold the curtain rod.

17 Shower Hang

Shower Curtain Version 2

The original shower curtain was made from plastic. It took too long to dry off and had some times would get mold on it. After quite a bit of searching I found a 130″ long polyester curtain. This curtain packed smaller, dried quicker, and did not get mold on it. At this point I came up with a better curtain rod system too.
