Put up our solar outdoor shower a couple of weeks ago, easy to install (we had to replace bolts to more heavy duty for our concrete floor).
The shower has been used everyday and is a great hit with myself and the grandchildren. There is plenty of water for a complete wash (I keep soap and shampoo/conditioner along side). Absolutely love my shower and would recommend that it installed in a sunny position, I also keep a bucket under shower to catch any drips or run off. :)
