We saw a similar shower stand in a camping store for around $75.  While I admit it was nice, it was made of teak, I thought pressure treated (PT) pine would work just as well.  I made two squares out of PT 2 X 4 pine.  Over the top I secured PT 1 X 2 pine as a slat floor.

The two squares are secured together with brass hinges, so the unit folds back on itself.  This is the travel position, and the 1 X 2 pine slats are to the outside.

I installed a brass window hasp where the two parts come together to secure them together for travel.  I tried several handles, but none seemed right.  I finally settled on a rope handle covered with a piece of PVC tubing I had left over from a previous project.

The photo to the left shows the prototype made out of 2X2 PT lumber.

This photo shows the stand assembled, with the shower hose hanging from the top.  Note the two top crossbars are screwed together with 3 1X3 pine boards.  These serve 3 purposes:

1. They make the frame more rigid

2. They provide a place to attach the screws on the back to hang the shower curtain.

3. They provide a place on the front to hang the shower head and soap holder.

The photo on the left shows a close up of the top of the stand, including the shower head and soap holder.  The soap holder is a standard item available at most RV stores.

A side view of the stand shows the construction.  When constructing a stand you can make the dimensions of the "boxes" created by the connection of the PVC pipes any size you wish.  Remember that the larger the box the more unstable the stand becomes.

The photo on the left shows the wing nut which holds the shower curtain.

The photo to the right shows a close up of the rear side of the top.  Note the screw at the top on which the shower curtain hangs.

The photo to the left shows the stand taken apart for travel.

Ok, Step 1 is to remove the stock shower hose form the outside faucet.  Don't worry, it's only hand tight!  You should now have the shower attached to a six foot white hose.

Step 2, using a cutting device (I used pruning sheers from the garden), cut the stock six foot hose into two parts, one about 1 foot long and 1 about 5 feet long.  You now have 2 hoses, with one having the hand shower on the end of it.  Using the parts you should have purchased, you will now connect the 3/8" PVC tubing to the part which has the hand shower attached.

To the right, you will see all the parts needed for this connection.  Note that I used a copper nipple as the connection device rather than a barbed connector because the inside diameter of the 2 types of tubing are different.

To the left you see the first completed connection.

You will now need to connect the parts for the "quick disconnect" into the other break in the hose.  To the right you see the parts for the "female" end of the quick disconnect.  I used an air line disconnect as it was the closest in size to the water lines I was using.

To the left you see the parts for the male end of the quick disconnect.  You will note I used a barbed adaptor to insert into the hose, as the threaded end of the male connector to push into the white stock hoes.

Once all connections are made, reconnect the short hose with the male end into the outside shower compartment.  When you need to use the shower, open the compartment and connect the two pieces of hose together.

Here is what it looks like when disconnected for travel.  No longer do you need to try to fit that hose and shower head into the little compartment.
