Cold Plunge & Sauna

This gym offers private suites equipped with infrared saunas and cold plunge tubs. Gym members describe the saunas as clean, effective for heat therapy, and featuring adjustable lighting, temperature, and music. The signature experience involves a 45-minute sauna session followed by a three-minute cold plunge, which many members find cathartic and rejuvenating for post-fitness recovery. However, the layout of this specific location is not designed for convenient alternation between the sauna and cold plunge, a process known as contrast therapy. Guests can also opt for a Vitamin C shower included with the suite instead of the polar plunge.

Staff

The staff receives consistent praise for being friendly, helpful, and accommodating. Specific team members, including CJ and Tara, are noted for providing exceptional hospitality, guiding guests through the experience, and proactively addressing needs. One isolated incident involved a staff miscommunication that interrupted a session, but the management addressed it by offering a credit for another location.

Atmosphere

The atmosphere presents a mixed impression. The private suites are described as clean and luxurious, offering a convenient and private experience. However, some members note the aesthetic feels more clinical than relaxing, comparing it to a medical office due to bright lighting and a prominent wall timer. The location at Assembly Row is considered convenient, quiet, and not overcrowded, with nearby shops and juice bars adding to the appeal.

Additional Amenities

Each private suite includes a shower. The gym provides a range of complimentary toiletries and extras for guests, contributing to a luxurious feel.
