Ok I'm not about to galvanise the whole wall or anything - google it, people do! But I want to cover a small shelf area at the end of the bath with metal instead of tiling it.
This is mainly because I don't want to silicon tiles onto wood, and they will bring the level up higher than the bath so I can't use my lovely bath trim tiles round the edge.
I am thinking, galvo steel or copper.
What is likely to happen to these metals if they get wet constantly and can I protect them with some sort of wax?
I realise this is an obscure question but any comments about metal in bathrooms are welcome
