When I did my extreme bathroom make over, I moved the diverter to the wardrobe wall and moved the head higher up on the wall. I am not tall 5' 8" but can stand under it and shower no problem.
I have not done it yet due to no curtain, but I do not see any issues with using it. I of course would use the facilities if they are present, but like the idea of having the ability. My wife and both of our daughters have used the bathtub. My wife says it is not her claw foot, but a huge luxury over the bathhouse shower. My oldest daughter loves it and thinks it is very cool to be able to take a bubble bath while camping.
I still need to make that template Tammy, It will come soon.
