Baan - Ice bath, Sauna & Spa

What is it? A garden bathhouse out west near Mahidol University, built around a Finnish sauna and a cold plunge you can set anywhere from 3C to 15C, depending on your nerve.

Why we love it: Baan rewards the trek out west. It’s built for first-timers: staff walk them through the cold, and you set the plunge to whatever you can stand. For co-founder Matteo K, it’s less about toughness than ‘listening to your body and building confidence over time.’ In real terms, if you can’t brave a freezing ice bath on your first ever plunge, don’t worry. Start where you feel comfortable and learn to enjoy the chill. A place you come to slow down, not to tick off a plunge.

Time Out Tip: Build in time to just sit in the garden between rounds – here it’s as much part of the ritual as the sauna and the ice. Add a Thai massage (from B450) to make an afternoon of it.
