About

A Japanese-style onsen in Sukhumvit with multiple mineral pools, a steam room, and a dry sauna reaching 90 degrees. After soaking, guests can enjoy traditional post-bath milk drinks — the closest thing to a Japanese bathhouse experience in Bangkok.

Yunomori Onsen is super relaxing, with warm thermal waters and a zen atmosphere that melts away all tension. If you come as a couple, the onsen is separated like authentic ones in Japan (men and women divided), but otherwise it's a paradise of pure bliss.

Yunomori never misses ! I could write 100 words but all you have to know is - quality onsen, great range (love the sauna), I think it’s a bit more compact than the Sathorn branch but still has everything you need. for 650b for a full day pass (not incl food prices - the restaurant inside is always good, steep but good food and nice atmosphere), I have spent several long afternoons / evenings at a Yunomori in Bangkok and will likely do so again.

Excellent place. Feels like in Japan. I only used the Onsen. 3 different Onsen pools and 2 cold water pools. A steam sauna and a 90degree sauna. After sauna you can drink the typical milk products offered in Japan. There is also a restaurant with a delicious looking menu and various massage/SPA packages offered on the 2nd floor. Went there every day I stayed in Bangkok.

I’ve been visiting Yunomori Onsen on Sukhumvit Soi 26 regularly, and I really enjoy the onsen facilities. However, my first experience with their onsen + massage package was disappointing enough that I need to share it. I hope this feedback helps them improve their processes. Called ahead to book a 90-min foot massage, figuring I’d do it first then chill in the onsen without rushing, a nice way to enjoy the new year holiday. So I walked in and bam 💥 they only let you do onsen BEFORE massage, no flipping it. Staff said it’s cuz massage oil messes up the water, but come on, foot massage barely uses any oil, and you’ve got showers right before the baths anyway. How do they even know if someone just came from another spa down the street all oiled up? If this is such a big deal, why not mention it during booking, or add a quick sniff test/check for all clients? Business is business, but these rigid rules just limit the client experience so much—they’re better off sticking to onsen-only visits instead of bundling massages that kill the flexibility. Felt like I got blindsided. The massage was average for the price. Worse, I got 60 min massage instead of 90. Pointed it out after, they checked and offered to go back to complete the massage time or refund, of course I would choose the refund as the experience was soured and I wanted to go. Then, as I was leaving, another staff member stopped me with a receipt for 60 minutes (proving they were “right” per payment) and tried to claw back the refund. It highlighted sloppy internal checks. Total chaos, no coordination between front desk folks. Very bad experience‼️ It’s frustrating cuz the onsen is great otherwise, but this massage add-on? Would’ve been perfect with some common sense flexibility.
