Bathroom cladding

[bluenosebaker]

I'm looking at putting cladding on my bathroom wall about a third of the way up with dado to finish.
Any ideas which wood would be most suitable and where to get?
Although it won't come in contact directly with water i'll still need to waterproof, any recommendations what to use?
I do intend to paint white.
Thanks

I have T&G wood cladding in my bathroom painted white and they do open up slightly in some area. If I did it again I would go for MDF T&G board sheet, quicker this way and no joint to worry about ! You can seal the MDF with the MDF Sealer. They are available in most diy stores.
