Everything we’ve learned about saunas and ice baths, in one place.
These are the guides we wish we’d had when we started. RönYen is based in Thailand, selling and installing saunas and ice baths — and using both most days of the week. The articles cover the practical side of owning them in a tropical climate: what to buy, how to size a heater, how to set up a sauna and cold plunge at home, and what the research actually says about the health benefits. No wellness-guru hype, just honest advice from people who’ve made most of the mistakes already.
New to all this? Start with the Getting Started guides. More interested in the why than the how? The Health & Wellness articles dig into the science and the day-to-day payoff.
If you’d like to see what we offer in person, you’re welcome to visit us at our Chonburi office by appointment — book a free consultation.
The sauna in a private garden is used four or five times a week by the same two individuals, while the one in the hotel is used from seven in the morning until ten in the evening by guests who have never used a sauna, do not read the sign, and will pour a bucket […]
For several years, I’ve been taking cold water baths, and the first thing that no one ever tells you is that Thailand “cheats” [joke]. The tap water stays at about 28 to 30°C year-round; if you fill a bathtub and then walk away, you’ll have a lukewarm bath. So before discussing which ice bath is […]
The majority of the enquiries come exactly as described. A person messages us to say that they would like a six-person sauna. We then request a photo of the spot where it is to be placed and receive a picture of the space beside the pool which, rather generously, is 2.4 metres wide. That isn’t […]
A six-person barrel is ฿110,252 cheaper than a six-person rectangle. You get the same number of seats, the same heater, and the same timber. The only real difference is the shape, and that actually matters. Most comparisons say it’s just about taste: choose a barrel if you like a rustic look, or a rectangle if […]
People often ask me if a timber sauna will just rot in Thailand. With forty-degree afternoons, ninety per cent humidity, and monsoon rains that feel relentless, it’s easy to think a wooden sauna wouldn’t survive here. But here’s the surprising truth: a sauna actually dries itself from the inside several times a week. Each session […]
I take care of ice baths for a living, so I’ve made just about every maintenance mistake you can imagine. I’ve left the lid off overnight under a frangipani tree, run a chiller with the filter only halfway in and heard it make unhappy noises, and let the water sit a week too long in […]
Most companies in this industry won’t tell you the price up front. You’ll usually see a nice photo, some words about wellness, and a button asking you to contact them for a quote. In other words, they want to know your budget before sharing the price. So here are the real numbers for three sizes […]
The install is the easy part. It’s the two weeks before it that catch people out. We show up, build the sauna, and finish up in a day for most cabins. Whether that day goes smoothly depends on what’s ready when we arrive. In my experience, every delayed install has come down to three things […]
Almost everyone has the same first question, but few say it out loud. People ask about the temperature, how long to stay in, or what to bring. But what they really want to know is if they’ll embarrass themselves. You won’t. No one is watching. That’s the main thing, and the rest of this page […]
Most articles on this topic are written by people who only sell one type of sauna. Infrared sauna companies often claim that traditional saunas are outdated and uncomfortable. Traditional sauna companies, on the other hand, say infrared is just a fancy heat lamp. Both sides are selling their products and not telling the whole story. […]
I started cold plunging in an inflatable. Most people do. Mine was a black drop-stitch tub on the concrete out the back, filled with tap water and bags of ice I drove to the shop to buy. It worked. I got in, I hated the first forty seconds, and I got the recovery I was […]
For the first few weeks, I used bagged ice for my ice bath. I drove to the shop, brought the bags home, poured them in, and saw much of the ice melt before I even got changed. By the time I finished, the water was already warming up again. The next morning, it was the […]

Outdoor and indoor cabins, barrels, cylinders and sauna + shower combos — from a compact one-person unit up to ten-person commercial rooms, all customisable to your space. Browse saunas.
Western Red Cedar and Finnish Thermo Pine both handle heat and humidity beautifully; Hinoki is our premium pick. We’ll match the timber to your budget and location.
Outdoor saunas are fully weather-sealed for gardens, rooftops and pool decks; indoor models are built for bathrooms, gyms and spare rooms. Both use indoor-rated electric heaters.
Most home saunas run on a dedicated single- or three-phase circuit sized to the heater. We’ll confirm the exact electrical requirement in your quote.
Both are food-grade and corrosion-resistant; 316 adds extra protection for coastal and chlorinated environments. We recommend the right grade for your site. See ice baths.
Ice works to get started, but a chiller holds a precise temperature day after day with no effort — the easiest way to make cold therapy a daily habit.
Our chillers take the water down to around 3°C and hold it there. Most people plunge between 3–10°C depending on experience.
A built-in filtration and sanitation cycle keeps the water fresh for weeks. We’ll walk you through simple water care at handover.
We’re open now in Chonburi, Thursday to Sunday, with Founding Member pricing until 30 September. The full experience opens 4 September — book ahead to be sure of a spot. Book a visit.
The Garden runs on advance bookings so every session has the space to itself — so book ahead if you can. That said, if you're passing and spot us, scan the sign at the gate or give us a call, and if there's room in the current session we'll happily wave you in.
Saunas, ice baths, a swimming pool and shaded lounge areas — everything you need for the full hot-and-cold circuit. Explore the garden.
The Wellness Garden is in Chonburi, easily reached from Bangkok and Pattaya. Full directions and parking details are on the garden page.
Yes — most saunas assemble in a day with two or three people and clear instructions. Prefer it done for you? Our team can handle the full install. Installation service.
Delivery to the spot, full assembly, levelling, heater fitting and a handover walkthrough so it’s ready to use the same day.
A firm, level base — a concrete pad, deck or paved area — plus a nearby power point. We’ll send a simple prep checklist before delivery.
Final connection should be made by a licensed electrician. We provide the full specification and can recommend trusted local contractors.
Yes — we deliver right across Thailand by freight, and ship internationally on request. Delivery details.
Most saunas are ready eight to ten weeks from order. Once built, freight to your address typically takes a few days, with tracking provided.
Standard nationwide delivery is included. For tricky access — rooftops, tight lanes or upper floors — we’ll quote any crane or extra handling up front.
Everything ships in a purpose-built timber crate to protect the timber and glass in transit — and the crate is easy to dispose of or repurpose.
