What did you end up doing? I'm very curious.

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 :-)

Hope post shows, got some weird error message

We're tiling our toilet room, which is only the width of the toilet with a small amount of space each side. I want tiles for hygienic reasons but am unsure whether to tile all the way to the ceiling on all 4 walls or only part way up...any opinions on what is 'on trend'? The bathroom in the adjacent room is tiled to the ceiling.
