Lily'sMom thank you so much for your reply! I really appreciate the input.. I like the idea of 24x24 on the floor, but I was worried it would be too big, or perhaps like you said, the tile guy won't want to mess with it. Also, our house seems to shift a lot with the seasons (we have cracks that we fix and they reappear the following season), so would the big tiles be more susceptible to this kind of stress?

We are leaving everything as it is.. I guess this is more of a bathroom update than 'remodel' :).

If we did diagonal tiles on the floor, would we do straight across on the shower and tub for some variety?

As for the shower floor, we'll definitely use a small 2x2 matte finish tile for traction. The Euromarmo one does not come in a 2x2, so we were just going to pick a coordinating tile from another brand. I guess I was wondering more if it would be weird to have the entire bathroom floor in matte finish, and then glossy on the walls. It sounds like it might be OK, though.

Thanks again for all your help!

Have you seen the matte tile? You'll want to use that for the floor. In your large bathroom, I'd use the 24 x 24. It provides a quieter, calmer feeling than the smaller tiles and has fewer grout lines. I think the layout depends on the size of the entry and what other tiles you might use.

With gold tile, I would restrict it to the floor only and do something different for the tub deck and shower. I have warm colors in my home but I use gold in small doses because it's such a dominant color. You have a lot of wall so you want to decide a paint color now too. I would be cautious about adding additional layers of gold in wall, tile, and counter.

What styles and colors will you use for the vanity area? Do you have inspiration pics?

If your house shifts you really need to discuss with who will lay the tile as to which size and underlayment will be best choice...

it can even be problamatic to use in the shower walls if the house shifts and the foundation moves because it might create stresses in the walls...

I would not use a larger format 24x24 tile in that situation... I think you would be best served for the floor using smaller tiles (12x12max) with something like a Schlueter mat on your subfloor or even a LVT--luxury vinyl tile--which now comes in waterproof choices for wet areas....

Larger tiles have a real issue with being curved in their backs because of the firing process...there can be issues with lippage between tiles...so even buttering the bottoms doesn't prevent the problem...

we used a variety of tile sizes in the bathrooms, but all were the same tile/color pattern the shower in the master bath has at least 4 sizes /shapes floors are small possibly 3x3 walls -bottom 60 percent and ceiling is 3x8 top 40 percent is 4x4 flooring in the rest of the room is 12 in square very happy with the bathrooms, all 3 are tiled the same (a porcelain marble look)

@clocktrasher Did you end up using the Euromarmo Crema Marfil porcelain tile? Were you satisfied with it? Do you have any photos?
