Bangkok's latest onsen, Panpuri Wellness, looks out over the bustling Ratchaprasong district.

The new opening from high-end spa name Panpuri sits on the 12th-floor of Gaysorn Village where its five mineral-rich onsen pools (separated into men's and women's zones) offer rest and relaxation from all the surrounding retail.

The all-day entry fee of B750 (B450 for kids aged 6-16) puts it a step up in exclusivity from Yunomori or Let's Relax, but does guarantee bathers a wealth of options—and some stunning views.

The signature Kusatsu pool features waters sourced from one of Japan’s onsen resort towns. There’s also a soda bath, vitality pool, cold plunge pool and another bath that changes according to the season.

Guys must take their kit off, but women are provided with underwear and tank tops. For those seeking more privacy, you can get your own room at B1,800/30 minutes.

Additional facilities include a steam room, Himalayan salt sauna and relaxation room, while Akasuri scrub is B900. Massages start at B1,600 for 60 minutes.

Just in front of the spa lies Panpuri’s Wellness Bar serving organic food and drinks all under 600 calories.
