We print to order removable landlord-friendly wallpaper. It's $55/msq for our standard range and we supply it in wall height drops so there's no waste. It's got the adhesive on the back and it sticks gently to flat and textured walls. We've never had a complaint about matching or difficult installing - it can't be stuffed up, it just takes time. It can be repositioned over and over and the edges butt join so it has the high end look of traditional wallpaper. Although it's temporary, it will stay up and look perfect for 10 years +. No nasty surprises with Phototex, it's a really nice product. Email me with questions! jen@thewallpapercompany.com.au

We have installed wallpaper behind glass splash backs on many occasions without any problems, the glass usually being attached by a thin beading of clear silicon applied around the inside perimeter of he glass, then fitted the day after the wallpaper install. MOST importantly the INSIDE of the glass be kept perfectly clean on install as even fingerprints will stand out

The mirrored wall certainly gives you a 'wow' factor and the floor is stunning. I wouldn't do a textured wall paper or metallic, I think you'd end up with too much going on in a small space. If anything I would perhaps paint the white wall in a very light grey to pick up the grout in the floor tiles.
