Bali Sauna + Kayun Herbal Steam Ubud

Bali Sauna + Kayun Herbal Steam sits in Mas, just outside central Ubud, and centers on a dome sauna where guests manage their own löyly, pouring water (sometimes herbal) over the stones to control heat and steam. The standout offering is the Amethyst Herbal Steam, the house's signature treatment, which guests say takes time to prepare but draws people back.

Cooling off happens in four individual cold-plunge pools split between two temperatures, 17°C and 10°C, giving a choice between a gentler dip and a sharper ice bath. Outside the sauna area there's a fire pit, a yoga space, and a café serving Japanese food, plus shisha for those settling in for a longer stay. The outdoor relaxation areas get mentioned often by visitors as a good place to decompress between rounds.

Staff work in Indonesian, English, Japanese and Russian, which matters given Ubud's mixed crowd of local and international visitors. The place runs as a day spa with no membership requirement: walk-ins are welcome and day passes are sold, so there's no need to book a multi-day package to try it. Children aged 7 and up are allowed, making it workable for families rather than an adults-only retreat, though it's worth confirming directly whether any sessions or times are better suited to kids.

It's priced at the affordable end for Bali's sauna scene. Hours run the same every day, 8am to 9pm, which gives flexibility for an evening sweat after a day of temple visits or rice-paddy walks around Ubud.
