SODO, WA

Little Red Day Spa occupies the historic Rainier Brewery warehouse between SODO and Georgetown, with multiple themed private suites (Painter's Studio, Moroccan Suite, overnight options, and more). Reddit recommends it for an intimate, private spa experience alongside Capitol Hill's private sauna rentals โ strong on soaking, massage, and atmosphere. Their public pages emphasize suites and bodywork rather than a standalone public sauna circuit; confirm whether your booked suite includes dry sauna or steam before you go.
Other spots in the same area or with a similar vibe โ always double-check hours and access on the venue's site.
