Relaxing Massage at Koh Spa








Onsen Wet Room
Ice Bath Recovery
Take a refreshing plunge in our 9°C ice bath at Koh Samui, designed to jump-start your body’s natural healing and nerve response. It’s the perfect way to recover and recharge after a hard day of training.
Athletes have been using cold water immersion for centuries, even before science caught up. Now we know that regular ice baths can speed recovery, ease pain, reduce anxiety and stress, support weight loss, and boost both mood and brain function.


Himalayan Salt Wall Sauna Room
Experience dry heat between 70–85°C that encourages sweating to detoxify your body, open pores, and cleanse your skin. The Himalayan salt walls release negative ions and essential minerals that can boost serotonin levels, support mood, sleep, digestion, and memory.
Breathing the Himalayan salt-infused air helps reduce respiratory inflammation, clear congestion, and ease symptoms of asthma, allergies, and coughs, making this sauna a powerful tool for both relaxation and respiratory health.


Traditional Thai Herbal Steam Room
Enjoy the soothing benefits of our steam room after a tough workout. With 100% humidity, the warm, moist heat helps relax muscles and joints while deeply hydrating and detoxifying your skin.
The herbal steam aids in opening pores and flushing out toxins, which can support reducing inflammation, balancing blood pressure, and relieving stress. Regular sessions may also boost your immune system by lowering the risk of colds and flu, while improving overall skin health and helping clear stubborn blemishes.


Hot Mineral Bath
Relax and recharge in our hot mineral bath heated to a soothing 40°C. The warm water eases muscle tension and calms the mind, providing effective relief from physical and mental stress.
Rich in beneficial minerals, regular soaking can help reduce stress and improve sleep quality. Studies show that a hot bath before bedtime promotes deeper, more restful, and uninterrupted sleep.
