O-Studio Hamilton is a recovery and wellness studio at 18 London Street in Hamilton Central. It offers float therapy in private, soundproof float cabins, where each tank holds 500 kilograms of Epsom salt in a warm solution. It also offers sauna and ice bath sessions for contrast therapy, yoga, pilates, massage and meditation. A recovery lounge has tools for bouncing back after exercise. The website says a programme of groups starts every Monday. Prices as at 2026 include one week of unlimited use of all services and classes, excluding massage, for $159, a single drop-in class for $95, and package deals for $210, or $70 per session. Gift cards and a free app are also offered.
Reviewers mention the sauna and ice bath most often, and the relaxing space. One customer and their sister tried an ice bath and sauna combination for the first time, and say the reception staff member explained everything and the 10-degree ice bath was a success. Another says the float instructions were clear and easy to follow, and that the facilities were very clean. A third says the communal sauna and ice area is spacious and cleaned after every session, and that the recovery space with compression boots helped after a hike. The website says 83 per cent of clients felt a clear improvement in stress after float therapy, which is its own figure.
