can you tell me if you used a light, medium, or dark gray grout?

We used Laticrete 89 Smoke Gray

Was the Laticrete Smoke Gray used on the black floor hex tile, as well? Thanks so much!

Yes, it was!

I love this combo! Can you tell me what the shower tile and bench tile is?

The wall is Arizona Tile: Core White 4x16 and the bench is from: https://www.tile-shop.com/products/neocim/neocim_decor.html

#37 KNNM/88FN Decor Fleur Noir 8x8

Can you tell me what the floor tile is please as well as the size?

The floor tile is from AdexUSA: #91 Vintage Black Hex 1" ADGL947.
