I at first could have looked right past this. The appeal of natural light in the shower but having comfort in feeling private is so cool. Those showers with exterior walls of windows or exterior access on the surface seems appealing but I would never be comfortable.
Ah-ha! I will try something like this! A place to sit & read, but not a place I can easily fall asleep, and definitely not a place where people will steal my office for a guest room :)
