I think the first mood board is more visually appealing and will make more of a statement. As for the black, they look great but i would aim at not making the room to busy, and just selecting 2 different styles of tile at the most. If you have renovated other rooms of the house or are trying to keep a theme through out - think about this also. Also i believe it would be more worthwhile for your home if you keep the two bathrooms similar, with minor changes like the size of the bathroom tiles - this wont be a big deal, as long as they are similar. Would love to know how you went and what you decided upon!

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

Hi Betty, There are lots of in between wall paper styles out there. We have a few examples of wallpaper feature walls (in a large room) or all walls (such as in a powder room). Here is the powder room link: https://www.houzz.com.au/photos/matilda-place-contemporary-powder-room-sydney-phvw-vp~92259318 I'll send through the other links in a few minutes. Hope these help to give you other ideas! Good luck. Cathy

Outdoor Or textured tiles certainly can be used inside provided it’s the right setting or area, for instance a laundry or smaller bathroom and en-suite... you just need the right cleaning equipment such as a sponge mop rather than a soft mop head and a good quality stone and tile cleaner. AquaKleen is a great brand. You’ll achieve a much more natural stone feel underfoot much like a natural stone ... with little to no slip or shine. Many people do use them and suppliers can shy away from recommending however they are completely fine to use indoors with the right equipment to clean.
