I'm quite lucky that we have quite a large bathroom for over here. There all normally so small in older homes! I have a a lot of space to fill and was only going to use the tiles in the bath and on the floor. I find fully tiled bathrooms very very confining. White wall for the rest, apparently, according to the design guru. But it's ok, I've been told when it comes time to decorate the garage I can have whatever I want!!!!

I think floor to ceiling tiles in a small bathroom can look quite nice. You may want to think about using a combination of tiles to add more interest and texture to the room.

Photos would help us a lot but mint and grey usually goes well with charred oak.

after watching my daughter and her husband agonize over the way their expensive timber floor has not held up well after 3 years, I would recommend tiles/wood look tiles with under heating. Their beautiful warm expensive floor looks like it always needs a clean and polish, not from neglect, they have cared for it well. One of the boards now has a slight and painful moan when it's stepped on :-( I grew up in a completely wood floor home and although it looked wonderful, my Mother hated it. ....and the mats ! Wood is a lot harder to maintain than tiles ,(no matter what the die hards say) the modern wood finishes are much better than they used to be.... But a piece of wood is rather arty no matter what it's used for and it does demand to be loved and cared for.....and if something goes wrong it's a lot more expensive to fix than sand and cement. Ultimately you have to be happy. BTW underheating tiles is warmer than timber :-)
