Reviews Summary

Let's Relax Spa is widely praised for its consistent quality, serene atmosphere, and excellent onsen facilities. Visitors appreciate the professional staff, the relaxing ambiance, and the complimentary treats like mango sticky rice. While generally highly rated, some find other spas in Bangkok offer a wider variety of onsen experiences or more thorough massages.

"I am an onsen lover. I have been visiting Let's Relax Onsen whenever I am in Bangkok for work before meeting my clients in the afternoon. I like going there at 10 am, when they have just opened for the day and there aren’t many customers. I usually soak in the onsen for an hour before heading for my 2hrs Thai massage.

The ambience of the massage room is quiet, peaceful and smell nice and the massage is very good. There are five pools at the onsen with different temperatures, along with a sauna and a steam room. The shower area has 16 seated showers and four standing shower stalls. The locker area is spacious, with a separate dressing area. There’s also a room with warm Himalayan hot stone bed baths and a cool-down room. A relaxing lounge is available if you’d like to take a nap.

The staff are friendly and helpful. They serve delicious mango sticky rice and tea after the massage. Your body and mind will definitely feel rejuvenated, refreshed, and relaxed. The onsen is usually not crowded in the early morning. Avoid the early afternoon and late evening as it tends to be crowded."

"Visited: Recently (2025) – freshly experienced the Onsen + aromatherapy massage combo.

What I loved:
•   Serene & elegant atmosphere: The moment I walked in, the blond-wood interiors and tranquil vibe immediately set the tone for pure relaxation."

Ronald Soo

"One of those business ideas that freaking works. Not a new one but done exceptionally well! It’s basically a hotel-situated-spa with excellent ONSEN style baths/showers/Sauna/SteamRoom and Additional Healing/Resting Space to relax or catch-up on some work.👌 PS Onsens are fully naked.

The Baths are slightly smaller than the new Lumpini branch but very similar vibes. Quality is consistent. Temps, cleanliness, facilities… Which is something we appreciate. You can achieve very similar Zen levels and healing at either locations.

I’m amazed at their 5 baths, heat bath, cold bath, milk bath, some other cool bath and their mini hydro therapy bath (massages)😈 it’s just great they have them!

Wifey opted to become a 12month member which gives her daily access plus a reduced 500baht access to her plus one. (Me) which is reduced from 750. — if you use the space more than twice a week. It adds up quickly and we found more value with the 12month package even tho we are only using it for 6 months. Because we planned on using at least 4-5 per week average. — If you are a couple and love your spa chills, this place is an excellent extension to any hotel or living arrangement in Bangkok.

It’s nice to have a second alternative chill base where you can spend a couple of hours to relax, get some work done.

Both venues Thonglor Branch (this one) and Lumphini Branch (newer one) have super late closing hours.

They are both in an excellent hotel which is nice.

both have a mini kitchen that serves food to purchase and they also provide free snacks and waters.

We are hunters of steam rooms, saunas located in hotels, gyms and spas, and this build is a good one for putting real work in the bath facilities.

Don’t think the experience will be perfect every time, the crowd gets busy at different times, so expect that too.

For what it is I think it’s pretty good value and definitely worth a visit once if you are ever in Bangkok and love public baths , saunas , onsens etc."

For Different Travelers

Tailored advice for your travel style

👨‍👩‍👧 Families with Kids

While Let's Relax Spa is primarily geared towards adult relaxation, families can still find ways to enjoy it. Parents might consider booking separate treatments, with one parent enjoying a massage while the other supervises younger children outside the spa area. Some branches are located near family-friendly attractions or hotels, making it a convenient stop. Instagram

For older children or teenagers who appreciate spa experiences, a foot massage or a shorter aromatherapy session could be suitable. However, it's important to note that the onsen facilities are strictly for adults and are a nude environment, so they are not suitable for children. Always check age restrictions for specific treatments if you plan to bring younger family members.

💰 Budget Travelers

Let's Relax Spa offers a good balance of quality and price, making it accessible for budget-conscious travelers. While a full spa package might exceed a strict daily budget, focusing on a 1-hour Thai massage or a foot massage can be a more affordable option, often falling within the 600-1000 THB range. Reddit

Visiting during weekday mornings can sometimes offer a more relaxed atmosphere and potentially fewer crowds, which might translate to a more serene experience. For those planning multiple visits, exploring membership options or package deals could offer significant savings in the long run. Reddit

couples

Let's Relax Spa is an ideal destination for couples seeking a relaxing escape together. Many branches offer private rooms where couples can enjoy side-by-side massages, creating a shared experience of tranquility. Instagram

Consider booking a couples' aromatherapy massage or a traditional Thai massage package. The serene ambiance and professional service make it a perfect way to unwind and reconnect. The onsen facilities also offer a shared relaxation experience, though it's important to remember it's a nude, communal area.

In-depth insights and expert knowledge

The Onsen Experience: A Deep Dive

Let's Relax Spa is renowned for its onsen facilities, offering a Japanese-style public bath experience. These are typically located in their larger branches, such as the one at Grande Centre Point Sukhumvit 55 and the Lumphini branch. The onsen areas feature a variety of pools with different temperatures, including hot baths, cold baths, and sometimes milk baths or hydrotherapy jets. Complementing the pools are steam rooms and saunas, providing a comprehensive thermal experience. Reddit

Reviewers consistently praise the cleanliness and maintenance of the onsen facilities. The locker rooms are spacious and well-equipped, often with separate dressing areas. After your soak, you can relax in a dedicated lounge area, which some visitors use to catch up on work. It's important to note that the onsen is a fully nude experience, and guests are expected to adhere to the spa's etiquette. Reddit

While the onsen at the Thonglor branch might be slightly smaller than the newer Lumphini location, the quality and overall Zen-like atmosphere are maintained across branches. For those who appreciate public baths and thermal therapies, the onsen at Let's Relax Spa is a significant draw and a key part of their appeal. Reddit

Choosing Your Perfect Massage

Let's Relax Spa offers a variety of massage treatments designed to cater to different needs and preferences. The Traditional Thai Massage is a cornerstone, known for its deep tissue techniques that help release muscle tension and improve flexibility. This is often recommended for those seeking a more invigorating and therapeutic experience. Instagram+1

Value and Membership at Let's Relax

Let's Relax Spa is often highlighted for its good value, especially when considering the quality of service and facilities. While individual treatments can be a treat, the spa also offers attractive membership options. For instance, a 12-month membership can provide significant savings if you plan to visit multiple times a week, even offering discounted rates for accompanying guests. Reddit

This membership model is particularly appealing to couples or individuals who frequent the spa. The cost-effectiveness of these packages makes it a viable option for extended stays in Bangkok or for those who consider regular spa visits a part of their wellness routine.
