I thought I was pretty cool because I have a sauna in the basement. But then I saw this photo of a London home with a subterranean spa (and there are more images from designboom). Wow!
Perhaps I still have echoes in my mind of the lifestyles of the rich and famous like Gianni Agnelli. Or perhaps it was thinking about Jaws and James Bond flicks. But I went into a “fantasy home reverie when I saw this picture. Very cool!
