What type of shower pan can I use outdoors to catch shower water that then is drained to a dry well. I would like to cover the pan with some type of wood or fake wood for aesthetics. Is there a how to for installing a outdoor shower. I have a septic system in place. The shower will be next to the house. I would like the water to be drained away from the house so there is less risk for water seapage into the basement.
