YA or Adult Fantasy - main character walks down a country road, when a door opens in the sky.

[Tom]

Discovers it to be a spaceship where the can fold unused parts of the ship into 2D space. When the main character goes to take a shower, the entryway pulses energy and that really does the cleaning, but everyone goes through the act of washing because otherwise they don't really feel clean
