After a short nap, I started feeling a bit hungry, so I decided to grab something to eat first.

Let’s head downstairs!

This place is really designed for comfort—there’s even an aquarium and a kids’ playroom. So yes, you can definitely bring children along here too.

Let’s head to the main hall area, where you’ll find the cashier counter for ordering food, along with tables and chairs. It’s the spot where people gather to chat, hang out, or even get some work done.

I’ve already ordered a few dishes. The price? No idea yet, since they just asked for my access wristband number.

While waiting for the food, I opened up my laptop to get some work done bit by bit!

It didn’t take long—around 5 to 10 minutes—before my order was ready. The cashier rang the bell, which meant I could go pick it up. I ordered boiled eggs, chicken sticks, and rice. For drinks, I just grabbed the bottled water I had left in the locker room.

The food was tasty! It really suited my taste—just wish the portions were bigger, haha.
After eating, I got back to work until around 10. By then, more people started showing up—high school students, parents, and others.
Once I felt a bit mentally drained, it was time to explore the sauna rooms. There are plenty of them here, and I’ll go through each one. Inside, most of the rooms are dimly lit, so I brightened the photos a little to make them clearer. Each sauna room is fairly spacious, easily fitting more than 10 people.
1. Yellow Soil with Amethyst
Yellow Soil (Yellow Clay) → When heated, this clay is believed to release stable, warm energy. It’s said to be good for detox, improving blood circulation, easing muscle soreness, and helping the body feel more relaxed.
Amethyst → When heated, amethyst stones emit far infrared radiation, which is believed to boost metabolism, reduce stress, and provide a calming effect on both body and mind.
So, stepping into the Yellow Soil with Amethyst sauna feels more like gentle body warming compared to a regular steam or hot sauna. The effect leaves your body feeling lighter, helps you sleep better, and makes your skin feel fresher. The temperature here is around 75°C. video inside






2. Himalayan Salt & Oak Charcoal
Himalayan Salt → The walls here are lined with Himalayan salt blocks. When heated, they release negative ions that are believed to help purify the air and make breathing feel easier. The effect is calming for the nervous system, great for reducing stress, improving sleep quality, and even thought to help with minor skin and respiratory issues (like asthma, allergies, or sinus problems). The sensation is usually a dry warmth, a bit different from a steam sauna.
Oak Charcoal → This room also uses heated oak charcoal. Charcoal is known for its detoxifying properties, as it helps absorb toxins and encourages deeper sweating. It’s said to boost blood circulation, ease muscle pain, and leave your body feeling lighter. The temperature here tends to be hotter than some of the other rooms, so you’ll find yourself sweating a lot more. Video inside





3. Ochre & Pine Tree
Ochre Sauna → This one uses yellowish-brown clay, which has long been used in traditional Korean remedies. When heated, ochre releases a steady, gentle warmth that’s believed to improve metabolism, ease muscle and joint pain, and promote better sleep. It’s often a favorite for those who want deep relaxation without the intense heat of other saunas.
Pine Tree Sauna → Designed to bring a natural forest-like feel, this sauna uses heated pine wood, releasing a distinct aroma that works like aromatherapy. The warmth from the pine helps relax the body, while its scent feels refreshing, clears the mind, and supports easier breathing. The overall relaxation effect isn’t just physical—it uplifts your mood too, making it great for relieving daily stress.. Video inside



4. Ochre Hot Kiln
This sauna room is designed like a large kiln, with its walls coated in ochre clay (yellowish-brown earth). It’s heated to a very high temperature—over 90°C—so stepping inside feels a bit like entering a traditional oven.
I couldn’t bring my phone inside because of the extreme heat.
Ochre is believed to naturally absorb toxins, boost blood circulation, and enhance metabolism. Since the temperature here is much hotter than the other rooms, your body sweats heavily in a short time, making the detox effect feel much stronger. The deep heat also helps ease joint pain, muscle soreness, and leaves you feeling light and refreshed afterward. Many people say that after just a short session inside, they come out feeling both deeply relaxed and re-energized.

5. Iced Room
This room is kept at around -9°C, lined with ice or maintained at an ultra-cold temperature—almost like stepping into a giant freezer. Its main purpose is to balance the body after the hot saunas. After sweating a lot and having your pores open from the heat, entering the iced room helps close the pores back up, refresh the skin, and reduce inflammation.
The icy chill also boosts blood circulation: blood vessels that expanded during the hot sauna shrink back down in the cold, which improves overall flow.
Other benefits include reducing swelling, giving a refreshing burst of energy, and making you feel more awake and alert after a long relaxation session. In short, the iced room completes the classic Korean spa hot–cold cycle, leaving your body feeling refreshed, balanced, and not overly drained after all that heat. Video inside








After checking out a few sauna rooms and the iced room, I kept exploring to see what else was around. To my surprise, there’s even a karaoke room! But it’s not free—you’ll need to pay extra, with the first hour priced at about 14 USD.

There’s also a movie room here! They play Korean dramas and other shows too. Super fun if you come with friends—you can watch, eat, and chat together while hanging out here, haha. Video inside




Right behind the TV room, there’s a cozier workspace. And don’t worry—there’s Wi-Fi available in every corner!

There are also two smoking areas here, so no worries if you feel like having a smoke!


And guess what—there’s even a gym here! Hahaha, how cool is that? Pretty awesome, right?!



After exploring to my heart’s content, I decided to take another nap since I was still feeling tired. Right under the stairs leading to the sleeping area, there’s also a chill spot like this—you could sleep here too, but it’s way too bright!

Around noon, I went back to sleep here. By then, the sleeping room was much emptier—only about five people left inside.

At around 2 PM, I woke up and went for another onsen session before getting ready to check in at my hotel, since my 12-hour access here was almost up. By around 4 PM, I checked out of Lasema, returned the access wristband, and paid for the breakfast I had earlier.

Breakfast earlier cost around 6.50 USD. Yeah, it’s a bit pricey, but what can you do—was hungry, haha! Plus, it was tasty, so still worth it.

Alright, let’s head back to the hostel for check-in!
