Onsen Time! My First Experience in Thailand

Right after Friday prayers, I hopped on a Grab bike to get here—it cost around Rp25,000 about (1.50 USD). It could’ve been cheaper, but Bangkok traffic was crazy since there was road construction going on.

Finally, I arrived at Yunomori Onsen.

Let’s head inside! After going up the stairs, the first stop was the sandal locker. Here, it’s mandatory to wear indoor sandals. You store your own sandals, take the provided indoor pair, and lock them up.

After that, I went straight to the reception to buy my ticket—just for the onsen this time, since they also have packages that include massages and more.

Here are the prices: Onsen only is 650 baht (around Rp325,000 or about 18 USD). They’re open from 10:00 AM to 11:30 PM, and you can go in and out of the onsen as long as you don’t leave the building. They give you a wristband with a sensor for your locker inside, and the key for your sandal locker gets exchanged and kept at the reception.

Let’s go! You can either take the elevator or the stairs— the men’s onsen area is on the 3rd floor.


Stepping into the onsen area, I found out that phones and cameras are a big no-no. But… I was a little cheeky and took a few quick shots just for my own documentation (don’t worry—no one else ended up in the frame!).

Right at the entrance, there’s another reception desk with yukatas you can borrow, or black shorts if you’d rather wear those for the indoor onsen.

Then comes the locker room—so many lockers! This is where everyone changes, which means yep, it’s all about going completely naked here.

Inside the locker, there were already two towels waiting for me—a small one and a big one.

I decided to just go completely naked—mostly because everyone else around me seemed to be doing the same, haha!
Right next to the locker room, there’s a grooming room stocked with all the essentials—skin lotion, moisturizer, cotton pads, cotton buds, hairdryers, combs, and more. I couldn’t snap any photos here since it was super crowded with people walking around (even though I had my phone with me 😔).

So, for the onsen photos, I’ll be using ones from the official website instead.

And now…

Welcome to the onsen area!

There are seven different pools here, and each one comes with its own vibe and benefits!”

• 2 Cold Pools (15–17°C)
  “These were seriously freezing for me—I could only stay in for a few seconds before my body felt completely numb, haha. Each pool comes with a little sign explaining the health benefits. Cold baths are great for boosting blood circulation, easing muscle soreness, refreshing the body, and helping balance your temperature after soaking in hot water. They’re also said to improve immunity and make your skin feel firmer.”

• 1 Bubble Bath (39–41°C)
  “This one’s like a jacuzzi with streams of bubbles massaging your body. It’s super relaxing, helps loosen tense muscles, improves blood flow, and just melts away stress after a long day.”

• 1 Micro Bubble / Silk Bath
  “The water here looks white because of the countless tiny bubbles floating around. These micro bubbles work wonders for deep cleaning pores, softening and brightening the skin, and improving circulation. The sensation is so soothing and leaves you feeling fresh and relaxed.”

• 1 Mineral Bath (super hot for me 🥵)
  “This pool contains natural minerals like magnesium, calcium, and sodium that your body absorbs while soaking. It’s said to help relieve muscle and joint pain, calm sensitive skin, and speed up recovery. The warmth gives a deep sense of relaxation, though honestly, it was a bit too hot for me!”

• Jet Bath (around 41°C)
  “These are like mini bathtubs for one person each—I think there were about five or six of them. They come with strong water jets and bubbles that massage your body while you lay back. Such a nice way to relax!”

• 1 Signature Yunomori Bath
  “This was my absolute favorite! The water had a tea-like color and fragrance, because it’s infused with tea, essential oils, and magnesium sulfate. It literally felt like soaking in a giant cup of tea! The temperature was around 41°C, but it didn’t feel overwhelmingly hot. Loved it!”

“The onsen area also has a Japanese-style washing station where you sit while using the provided soap, shampoo, and conditioner. Plus, there’s a sauna (80–95°C) and a steam room (45–55°C) if you want to sweat it out even more.

The main difference between the steam room and the sauna lies in the type of heat and humidity.

In the steam room, the air is filled with hot steam and almost 100% humidity. It feels warm and damp, making you sweat quickly while helping to open up your pores, cleanse your skin, and keep it hydrated.

The sauna, on the other hand, uses dry heat, usually from hot stones or an electric heater, with low humidity. The air feels drier and the temperature can get even higher than in the steam room. Saunas are great for sweating out toxins, boosting circulation, and relaxing your muscles.

In short: the steam room is warm and humid, while the sauna is dry and hot. Both are amazing for relaxation and health, but the sensations are totally different.

Okay!! That wraps up my first session—it’s already been over an hour! My hands were starting to wrinkle, so it was time to slip into a yukata and take a little stroll in the garden before having a quick nap. By then, it was already 4 PM.

By the way, at the men’s onsen reception there were plenty of yukata designs to choose from, but for some reason I just went with this one, haha.

Okay, time for a little walk! The nap area is located in the same complex, just around the building. You can follow the signs, or if you’re unsure, just ask one of the staff—they’re always around and happy to help.

Before taking a nap, I grabbed a cold drink first. And guess what? It’s free—yay

Next, I headed to the building next door, passing through Yunomori’s signature garden along the way. Such a peaceful little spot—it really adds to the whole relaxing vibe.





Walking further into the next building, I passed by the Yunomori café and restaurant. Then I came across these white curtains—just slip through them and head upstairs.



And finally—you arrive at the nap area! Shhh… quiet, please. Here, I spotted a cupboard filled with blankets, and yes, you can totally grab one to make your nap extra cozy.

Inside, there were so many sofa beds—and it was pretty full too. Some people were working on their laptops, others were napping, and a few were just scrolling on their phones. Basically, you can do whatever you like here, as long as you keep it quiet.


Oh, and you can even charge your devices here—super handy!
After chilling here for a while, I started to feel hungry. Since I couldn’t leave the Yunomori area (or else my day pass would be forfeited), I decided to just eat at their restaurant.

I had a feeling the food would be pricey though!
Wanna check it out yourself? Just scan this QR code, haha.
I ordered this one,it was actually pretty good! The price was around Rp150,000 about (9 USD) tax included, and you settle the bill at the front reception when you check out.



Alright, all full—time to head back for another round of naked soaking in the onsen!

As the evening went on, it got busier, with around 30–40 people. Lots of fellow foreigners like me, mostly Westerners, and about half were locals.
I ended up staying here until 10 PM!Haha, because come on, I paid Rp325,000 about (18 USD) , so I had to make the most of it!

Inside, there were also long benches where you could just sit and relax—because let’s be real, you can’t stay in the water the whole time.

As for flirting or cruising? Well, I did get approached by two people, but they were polite and asked nicely. Overall, everyone was really friendly. I even had a nice chat with someone from China, and we became friends! Honestly, it felt super safe—especially for someone like me who usually has a bit of trust issues about onsen/sauna experiences.

So yes, I totally recommend coming here if you want to try an onsen or sauna in Bangkok. Best to come in the morning and stay as long as you can—worth every minute, haha!

I’ll definitely be back, Yunomori!!

Tomorrow, I’m planning to check out a men-only onsen. I wonder what that’s going to be like?
