Usually I go for larger tile, but here I am somehow more drawn to the smaller ones. For a kids bath it’s a little cuter. The larger ones look very grown up, especially with your other choices. That said, I think the larger ones look good too. Best of luck.

Love the hex tiles; they are super cute, plus I think they are better in proportion to the size of your tub tile.

IMO in any bathroom the fewer grout lines the better and I happen to like 12 x24 tile on both the bathroom floor and the shower walls and both the same. BTW cute really never figures into kids spaces since they grow up quickly. I would make this as practical as possible but still nice looking. Please no Edison bulb fixtures in any space IMO but for sure not in bathrooms or kitchens good lighting is a must in both spaces.

I like the hex, but i do worry about the grout. I’d probably use gray. I‘m also concerned about durability. Lots of the hex tiles are chipped on the edges right out of the box.

Hex for sure.

Hex tiles are cute AND classic; we're about to put marble hex tiles in our new master bath. To me, the larger tiles could be a slipping hazard in a room where the users might not be the best at staying on the bath mat when they're dripping. I think you're smart to go with a darker grout color.

The hex look the best.

hex. gray grout.

those other tiles just don't look right. too formal looking, especially if the tile surround is staying as is.

btw, have you thought about doing a diff color since this is a kids bath? (and if the white tiles are staying in the tub area, doing a diff color on the floor will add some contrast)

white tiles will be a cleaning nightmare. don't even think about doing white grout.

what about a larger hex tile (less grout lines)?
