Amba

Amba is a day spa in Tambon Bo Put on Koh Samui built around a hydrotherapy circuit rather than a single treatment room. The core facilities are a sauna, steam room, hydrotherapy pool and ice bath, meant to be used in rotation for the classic hot-cold wellness routine rather than as one-off add-ons.

Massage treatments are offered alongside the circuit, described as customized to the individual rather than a fixed menu, covering general relaxation through to muscle-focused work. The spa is adults only, so it's geared toward a quiet, uninterrupted atmosphere rather than a family-friendly pool day.

On site there's also Amba Bar & Restaurant, which runs its own food and drink menus focused on low-calorie, additive-free meals - a practical detail for anyone planning to turn a visit into a half-day or full-day outing rather than a quick pass. Walk-ins are welcome, and the price tier sits in the moderate range for the island.

Amba is open every day of the week from 8:30am to 10pm, which gives some flexibility for timing a visit around the Koh Samui heat, either an early soak before the sun gets high or a late-afternoon session into the evening. The address is on Bond Kai Road in Bo Put, Koh Samui.
