BATHHOUSE Spa at W Las Vegas

3940 S Las Vegas Blvd, Las Vegas, NV

BATHHOUSE is the minimalist spa inside the all-suite tower at the south end of the Strip that opened as THEhotel, became Delano Las Vegas in 2014 and was rebranded W Las Vegas in December 2024. The spa carried through the rebrand: about 14,000 to 15,000 square feet of slate and water with a redwood sauna, a eucalyptus steam room, heated and cooled whirlpools and a cold plunge room, plus a dozen treatment rooms. Day passes have been sold to hotel guests (around $50 historically) and the public (about $100 per recent reviews), and treatments include facility access. Since the W takeover, at least one reviewer reports the wet area has become co-ed, so bring swimwear. The spa has kept short hours, 8:30 a.m. to 5 p.m. and closed Tuesday and Wednesday in recent listings, and guests must be 18 or older. Book by phone, since online information is thin after the rebrand. It is quieter and smaller than Spa Mandalay next door, which suits a focused sauna, steam and plunge loop rather than a full spa day.
