Wood For Outdoor Shower?

[2na]

I just stack a cord of wood around mine - the advantages of a cottage in the wilds of Truro.

Larry, make it as big as possible, with southern exposure (to get sun and block cold winds) and a double showerhead (double showerhead for water coverage more than anything).

My decking is just standard pt, and it is not slippery, but I worry about the breakdown of the wood and monster splinters. When I re-do it I would use a composite, maybe a light grey to keep the heat factor low..
