How about some pictures?

based on the drawing, the wall where the bed is. HOWEVER, you mentioned that this drawing is not a true depiction of the furniture you will use and the wallpaper. if that is the case, i think the wall paper can work on either wall, it all depends on how busy this wallpaper is and how "plain" the bed is. if you go with a busy wallpaper behind the bed, you may want to keep your bed and bedding on the minimal side so that there is a good visual balance to the overall composition. if you go with snazzier bedroom furniture, then a busy wallpaper may be a bit much and you may want to put it on the other wall or use a textural option to serve as the bed's background rather then another focal point.

Hi, I'm wanting to purchase 3 rolls of Gardens of Amsterdam 64133 wallpaper made by BN Wallcoverings. I'm happy to get it from any country and can arrange freight to New Zealand. Can you please advise where I can purchase it? I have found 1 roll in NZ which is batch code 417.1 so if there is two more rolls same batch that would work too. Thanks for your help. Best Regards, Leah Boakes

Yes, I had noticed a lot of pics on Houzz, that's what gave me the idea! I certainly wouldn't put it IN the shower! We have a tiled shower, but the tiles only go as high as the glass surrounds, so there is about 30cm of painted wall above the shower, which is the part I was worried about with steam etc.
