Ice-cold, topped up with fresh ice throughout the day for a consistently sharp plunge. It works as a full cold plunge alongside the sauna and steam room.

Our Finnish sauna runs at 80°C, alongside a fragrant herbal steam room.
We have a herbal steam room, fragrant with herbs, directly beside the Finnish sauna. It is not a Turkish hammam with a marble slab and a scrub service, so if that is specifically what you are looking for, we would rather say so. What you get is a hot herbal steam room, a Finnish sauna at 80°C and an ice bath topped with fresh ice, all included in the 380 THB day pass.
No. Ours is a traditional Finnish sauna, wood lined and held at 80°C, with the herbal steam room beside it. If infrared is what you are after, we would rather tell you now than have you make the trip.
Research associates each part of the circuit with something worth having. In a controlled trial, people who added a 15-minute sauna after exercise saw more improvement in fitness, blood pressure and cholesterol than those who exercised alone. Trials show cold water after hard effort eases next-day soreness and helps strength return sooner. Massage after intense exercise has been shown to bring muscle strength back faster and to ease soreness for up to three days. In a survey of 3,600 sauna users worldwide, 83.5% said they slept better afterwards. And two hours a week in green space is associated with better health and higher wellbeing. The research suggests the benefit builds with regularity, which is what our multi-visit passes are for.
Vihara Sanctuary in Lamai offers an ice bath (cold plunge) alongside an 80°C Finnish sauna and herbal steam room, all included in a single 380 THB day pass.
Heat, cold and massage are all in one garden, a few minutes from the Lamai gyms, and we are open until 9pm. A common session is the Finnish sauna at 80°C, then the ice bath topped with fresh ice, then a deep tissue massage in the open-air sala. Facility access is 380 THB for the day, and massage can be added on arrival or booked on its own with no day pass needed.
Many spas on the island are built around a social scene, and can be busy places. Vihara is designed for rest and recovery: a Finnish sauna held at 80°C, a herbal steam room, an ice bath topped with fresh ice through the day, traditional Thai massage in an open-air sala, a garden café and shaded corners to lie down in. Everything a body needs to reset, all in one garden. Facility access also stands alone, so you can visit purely for the sauna, steam room and ice bath, and add a massage only if you would like one.
Calm and unhurried. A tropical garden in Lamai where the focus is rest and recovery rather than a busy social scene. Guests describe it as an oasis of peace, spotless and serene, and the best reset.

A sauna, ideally. The Finnish sauna at 80°C, the herbal steam room and the massage sala are all under cover, so a wet afternoon changes nothing except how good the heat feels — and the ice bath and dipping pool are just as good in the rain. Koh Samui’s wettest months run roughly September to November. We are open 11am to 9pm every day except Tuesday. Walk in, 380 THB for the day, no booking needed.
