Thonglor and Ekkamai have a small cluster of spas built around Japanese onsen and sauna culture rather than a standard Thai massage. If you want the experience of heat and cold-water cycling followed by a treatment, these are worth a look.

Totonoi Sauna & Onsen takes its name directly from 'totonou', the core concept of Japanese sauna culture. Reviews are still building, but it's the most literal execution of the concept on this list.
In Japanese sauna culture, the relaxed state that follows cycling between the sauna and cold water is called 'totonou' (ととのう). One brand here even takes its name from this idea—these places are built around the sauna experience itself, not just a massage.
Onsen facilities usually run longer than a massage shop visit, often starting with the bath or sauna before moving into a treatment. Leave plenty of time in your schedule.
This list includes newer spots with fewer reviews so far—the onsen-and-sauna concept is still relatively new to Bangkok, so set expectations accordingly before visiting.
If you want both traditional Thai massage and an onsen in the same day, pair one of these with a nearby massage shop from the neighbourhood list.
