No wood tile in a bathroom. It just doesn't look like it belongs in there IMO. Are you set on slate? It's pretty dark, especially for a bathroom that doesn't have a lot of light. It will feel like you're showering in a cave. Rethink the stone flooring too, it can be tricky to clean. Slate is also busy, so having a busy floor too means the two are fighting each other.

I agree with the above comments. The palette is too cave-like. Lighten everything up, or add a lot of lights. The whole slate thing is very 10-15 years ago. If you want slate, go with very light tile, like white or pale gray on the walls, and choose a dark charcoal slate. This is much more current. Sorry to throw a wet blanket on your plans.

I like it. Keep in mind the tiles will look different colours when wet. Much stronger colour. We had it in a bathroom once that we still miss. (The walls were white, just the floor and border were slate). So beautiful. not sure on the wood in a bathroom though but like the slate and 'pebble' one

I would probably do the floor and seat in the slate and the rest white/beige/cream, whichever you prefer. Maybe the pebble one for a splash back behind the sink so there is less of it to clean

It's beautiful. If you love it, go for it.

I think 12x12 tiles are outdated, is there option for 12x24 tiles? Wood pattern, slate and pebbles - it feels too busy and dark. Have you thought to introduce tiles in solid lighter color?

Wood pattern tile will work for floor and may be to use it as a detail on the shower walls or/and seat. Use neutral pattern/color tiles for walls. How about linear drain along the seat?

I love the slate look, and I love the pebble flooring.....if you love it, I would go for it! Nothing wrong with rustic in my book; but, I lean that way 100% anyway. I personally would lean the more rust/brown route than the gray route, but that's my personal preference.
