Plan SDB avec côtes
A walk-in shower with no glass. Win. A tub that could also face out so that you could see the fireplace in the bedroom from the tub, with windows along the wall for lots of light. Double bonus.
This one is a must have.
Keeping the benchtop, sink, and the rest of the bathroom simplistic, this allows the 3 dimensional floor to ceiling tiles to be the feature of the bathroom, while not being over the top
Thinking of remodeling the current master sunken bath/shower with concrete. This one here is pretty darn cool.
