A bath with a view. It's also covered — imagine yourself immersed in hot water on a cold and rainy night, the branches dripping all around you.
A shower and bath combo in its own little (well, not so little actually) outdoor room, complete with windows, tile and a ceiling of tree branches.
Outstanding in its field! I'd float some of that rosemary in the water for nature's own aromatherapy. Oh, also, there seems to be a dragon in the tub. Hope you don't mind.
The best of both worlds: the indoor-outdoor tub. A view, fresh air, a little sunshine. Or you can close the doors and still see the expanse of nature all around you.
Another indoor-outdoor example, this time with a gorgeous copper tub on a bed of river stones.
I love the modern, casual look of the corrugated metal walls and the cement floor. It's unfussy, but it looks finished.
This outdoor shower is indicated by nothing more than a tile arch. If there's plumbing nearby, this would be a fairly easy project (not for me, but for someone handy and patient).
The outdoor claw-foot tub is so romantic.
This poolside shower reminds me of the little beach cabanas in Europe. It's a bit closed in, but you do get to shower in privacy (no points for potentially being caught naked).
This shower with a separate dressing area is the full monty. In warm climates this could work as your only shower.
It would be a real shame to live in Hawaii and not have some sort of outdoor bathing setup. This one has an indoor tub and an outdoor shower surrounded by a volcanic rock wall. Privacy, luxury and tropical breezes.
Brilliant human-and-dog shower combo (except when the dogs escape while soapy and make a break through the dog door). I love the clean, white corner. Simple and modern.
A shimmering green tile wall is both bathroomy and gardeny. It's almost like a piece of art.
