Let there be light! Natural light is much more flattering than fluorescent light, and when is this more important than you're walking past a mirror in the buff?
The natural light here even allows plants to thrive.
Blocked glass allows light to show through it without letting pervs take a peek through it.
This window allows you to gaze outdoors from the shower stall and the tub.
Blue tiles + the view = the feeling of sea and sky.
A great view from the tub.
