Spa Aquae

Spa Aquae sits inside the JW Marriott Las Vegas Resort & Spa, part of The Resort at Summerlin complex at 221 N Rampart Blvd, a few minutes from the Strip and close to Red Rock Canyon. It's a hotel spa in the upscale tier, built around 18 treatments that cover massage, facials, body scrubs and wraps, waxing, scalp and hair treatments, manicures and pedicures, and paraffin hand treatments.

Couples massages are offered for those visiting as a pair, and the facility is split into separate men's and women's lounges, each with a steam room, plunge pool and therapy bath on hand for use before or after a treatment. A foot bath and makeup services round out the service list, and men's-specific treatments are also available.

Access works two ways: hotel guests can use the spa as part of their stay, and the property's destination fee materials note that Marriott Bonvoy Gold Elite members and above get daily access to Spa Aquae included. Day passes for outside visitors are also offered. The spa is open every day from 8am to 7pm, and booking or questions about current day-pass terms are best handled by calling the spa directly at (702) 869-7807, since pricing for individual treatments isn't listed online.
