A house we are considering as open tiled showers similar to this. The tile is brown (not gray) and it (thankfully) has no window right there at the shower! I love the idea of an open tiled shower! No glass to keep clean, no curtain driving you crazy!
Bathroom in 'Carriage House' by Hare + Klein Design: originally built in 1850 as a carriage house, it was converted into a metal castings factory in the early before more recently being transformed into a home.
A beautiful contrast between modern and rustic. Reclaimed wood bench, and a patterened stone tile wall blend gloriously in this open raindance shower. Dyna - Portage Bay - industrial - bathroom - seattle - by Dyna Contracting, Houzz
