My bathroom walls are going to be finished with either tiles on marine ply or painted plaster on "Green" plasterboard. Now there is a tricky space beh ind the towel rail that protrudes too far. I can't cut the brackets support ing the rail much because the towel won't fit behind. My idea is to replace the 2cm ply behind the rad with 1cm thick ply and paint it a similar colou r to the tiles. Without the tiles I will save 2cm thickness of wall. Where the towel rail is located in the bathroom, this thickness is crucial.
I have a few descriptions online that painted ply has been used successfull y on kitchen floors. Now if I prime, undercoat twice, paint, then seal twic e with matt polyurethane varnish (I am thinking of giving the treatment you would to the hull of a wooden boat !) will mean the rad will receed a vita l 2cm and mostof the painted wall will be hidden behind the towel rad anyw ay.
Could this work? (please say yes). Better than that, has anyone experience of painted plywood floors in kitchens or bathrooms?
