Milestone & reclaimed wood Source: Mizono chose to use Milestone in the bathroom because it's softer and more forgiving than concrete. The resin sink is lit by LED lights. The Japanese-style soaking bath is sunk into the floor.
Another bath inside whower idea: factory window shower - the BEST idea! Imagine this done huge-Japanese-bathroom style with an old claw-foot tub in an oversized shower, so you could have overflowy baths in a shower the size of a small room.
