Secret Hidden Toilet Door - Using Original Book Works - One of the Best Hidden Doors! 

I had that wallpaper specially made from an image of the Bodlian Library, it was digitally altered slightly to remove people from it ;-). There are many comapnies who do this now, just make sure they're a good one & that you choose matt paper!

Thanks very much, it did look great & was a real success. I took people up there who wanted the loo & I would stand there saying, here it is & they would say 'where?' It was done very well, but I think my best advice would be to always obliterate the original door shape, so make the pretend shelves much wider/ taller, as we did here, this immediately tricks the brain as it can't see a door shape. The only thing I'd do differently today, this being 2012/13, is to do a coloured toilet, as the white does jump out at you quite a lot.
