Roll out of bed and into the shower? Not me. I haven’t needed a water-wake-me-up since high school. What I want this for is the reverse: I take hot relaxing baths and showers at night and then regret the trek all the way to my bed to collapse in a melty pile of fleshy goo. With this built into my mansion or luxury apartment, I could just keep a towel in the middle and do a quick wash-to-sheets.
