Here are a couple of pics of my shower mod that is inexpensive and easy to install. Gives a little more elbow room to the tiny shower and every little bit helps. The most expensive item was the heavy duty shower curtain-actually a liner that happen to be a close color match-wife approved.
The tubing is 3/4" pvc with pipe clamps at each end.
The other cross tubes are for drying towels and clothes with std. closet end cups.
