Wood Shower Walls? YES! The secret to making this wood shower work is the air gap behind the wood so it can dry out! I would dare to say this is easier than a tile install too. This is an un-proven design so I'm not sure I'd use this in your Master Shower but how is this any different than an exterior deck? My Builder Friend Jake Bruton came up with this design and I suspect it'll last a LONG time and be a super cool feature of his home office too. Both he and I believe in the Schluter tile systems for waterproofing, and this Accoya wood is a great choice for any exterior project.
