Downtown Seattle, WA
The Spa at Hotel 1000 is a full-service downtown spa (LXR Hotel 1000 at the waterfront edge of Belltown/Downtown). Locker rooms include a dry sauna for use before or after scheduled spa services; guests book massage, facials, and body treatments. The spa emphasizes quiet, robe-and-slipper relaxation, complimentary valet during scheduled services, and premium skincare lines. This is not a drop-in public sauna studio — access is through spa appointments or hotel context.
Other spots in the same area or with a similar vibe — always double-check hours and access on the venue's site.
