Every hotel spa is running the same trick, and it isn't the eucalyptus towels. It's material honesty — stone, wood, clay and water, warmly lit, with nothing plastic in sight. Once you see the trick, you can run a spa bathroom at home, in a normal-sized room, on a normal budget.
The ten bathrooms below run it ten different ways: cream travertine and gold, cool blue limewash, a Moroccan terracotta retreat, a moody copper tub under stone. Several are achievable with paint, panels and lighting alone — I've flagged the renter-safe ones as they come — and each image opens the complete design behind it. Towels optional, but recommended warm.
