Alright, this may sound odd but I like the look of OSB and would like to use it in my shower, I’m wondering if anyone has seen or done anytyhing of the such? My idea: multiple coats of poly for sealing and either stainless hardware to apply to studs or have a cement board backer and use construction adhesive to adhere to the concrete backer 1/4″ gaps btwn sheets caulked for expansion. Any ideas?? Any thoughts? Any help is appreciated.
