Glass Floor Over A Creek...Years ago the Disneyland hotel had a section of their lobby done like this as well. In fact, I believe that the Walt Disney World Wilderness Lodge (WLO for the Magoo's) also has a floor like this.
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.
