IMHO wood tile looks best in places that wood would have been used so a shower wall not so much I assume you removing toilet and tub in the bathroom you are asking about so i would do subway tile except on the floor

Yes. I am not keeping the blue beasts. Although another ten years they will probably be back in. I'm down with the use of wood tile on the walls. I actually currently live in a lake house where the shower walls are teak, so I know it can look good.

I like that wood look tile you have chosen. Would look great on the floor. I've seen it done in showers and i'm not really digging it, but since your mind is made up, are you doing it horizontal or vertical (rather than offset brick pattern. Maybe thats what I don't like. I think it would look good if you laid them out like large format tiles) Since you live at a lake house, why not use real reclaimed wood behind the vanity?? maybe something with a little color in it to break up all the white? What does the vanity and countertop look like?

In this pic, I like the wood coloring because it warms up all of the white.

I agree that the wood tile would be more important as flooring. Let it be the star. Do not use clashing textures or distracting patterns (subway) on the other surfaces. Keep them simple and complementary. Try 16" square inexpensive white matte finish square edged tile with narrow joints for the walls (to the ceiling). You need a good tile person to keep everything flat. Shine will be provided by porcelain and chrome. The floor will steal the show! By the way, the above photos show what too many star materials look like together: not a good marriage.

I've seen dark wood tile look very nice on shower walls. For whitewashed wood tile to have an impact and look good above a tub, I think it would need to coordinate well with the color of the tub and be cut shorter and offset (vs. stacked in long lengths as shown in the photo). If the tub color is that shown in photo #1, I don't think the whitewashed tile looks like an ideal complement to it.

Floor, not vanity. I'm not a huge fan of tile on every surface, so be careful about other choices and consider advice you have gotten so far on this thread. Also the point about contrast between shower and tile is a good one, but in the end it's your bathroom, so if you are in love with the whitewashed, go for it. But keep it to shower and floor, in my opinion.

The room looks small. I understand that you love the wood tile but the "grain" makes it busy. I think since your mind is made up you should use it in the shower but no where else. I also would not tile the vanity wall. I think that is too much tile for the size of the room.

I found this picture, it is not a good look IMO.

What are you using for countertop?

Hmn. Now I might have to go re-borrow that tile since it's not return-able and make sure it works with the white tub. Wouldn't ever do wood everywhere, either. Even vanity wall would be shower wall then wainscoting height. Of course proportions aren't right and it's super rough but my 'subway' tiles are 4 or 6x10, not the small ones. Wall isn't flat enough to go larger than 6x36 or 12x12.

Of course this bottom one is problematic because I'm supposed to be driving 5 hours to a job for tomorrow, yet I need to order tile today and I would have no idea what to use on floor, as grout line accent, or what goes on right hand wall. The first one I just need to check that the whitewashed tile would work (since that isn't the exact tile I'm using and I'm now concerned). It's just an image that was close, that I pulled.

I thought the whites would work, but maybe only in bright light? (Which the bathroom does not have.)

Vanity is the gray color, which I am a little worried the white wash will become too tan, en masse. (It looks okay here because the white has a blue cast to it but I've been burned with small samples before.)
