A personal infrared room in less than a square metre. The RY-900 fits where a traditional sauna never could — a bathroom corner, a bedroom, a condo balcony nook — and plugs into a standard power socket. No dedicated circuit, no electrician, no site work.
Four low-EMF carbon panels wrap warmth around you from the back, both sides, and your feet. Set the temperature and timer on the in-cabin touchscreen, connect your phone to the built-in speakers, and settle in. Infrared works at gentler air temperatures than a traditional sauna — 25 to 67 degrees — heating your body directly rather than the air, so sessions are comfortable from the first minute.
The cabin is hand-built in Canadian Hemlock with a full-height tempered glass door and side window, and arrives as a flat-pack kit that clasps together in under an hour.
Customisation
The RY-900 is a standard model, but it does not have to stay that way. Custom sizes are available if your space needs something slightly different. Talk to us about lead times for custom builds.
The RY-900 ships as a compact flat-pack kit, delivered across Thailand and internationally. Every panel is pre-built and pre-wired — assembly is a clasp-together job for two people, no cutting, no drilling, no trades.
Most owners assemble the RY-900 themselves in under an hour. Stand the panels on any flat, dry indoor floor, clasp them together, fit the roof, and plug into a standard household socket. If you would rather not lift a finger, our team offers an installation service as an optional add-on — ask when you order.
If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.

After each session: prop the door open and let the cabin dry. This single habit does more for the life of a sauna than anything else on this list.
Weekly: wipe the benches with warm water and a soft cloth. No detergent, no bleach. Sauna timber is left unsealed on purpose so it can breathe and absorb moisture.
Monthly: check the heater stones. Stones break down with heat cycling. Restack them so air can move between them, and replace any that have cracked.
Yearly: inspect the roof shingles and the door seal, and check that fixings are still tight. Timber moves through a Thai wet season and a bolt that was tight in January may not be in September.
Exterior timber can be oiled if you want to hold the colour. Left alone it weathers to a silver grey, which is a finish rather than a fault.
Stock items can be returned within 7 days of delivery in resalable condition. Custom and made to order items cannot be returned once production has begun. Faulty goods are repaired, replaced or refunded at our cost.
Quote Validity
This quote is valid for the period stated on it. Prices and product availability are subject to change after the validity period.
Payment Schedule
Deposit required upon order confirmation. The remaining balance must be received in full prior to delivery.
Deposit Forfeiture
The deposit is non-refundable. If the Customer cancels after production has commenced or refuses delivery, RonYen Wellness retains the deposit as liquidated damages.
Delivery Date
An estimated delivery date is agreed at the time of order confirmation. The Customer must ensure the delivery location is accessible and a responsible person is present on the agreed date.
Failed Delivery Fee
If delivery cannot be completed due to the Customer's unavailability on the agreed date, a fee of 1,000 THB per day applies until delivery is successful, payable before the goods are released.
Rescheduling
Any change to the agreed delivery date requested by the Customer must be made at least 7 days in advance and is subject to the availability of RonYen Wellness.
Risk Transfer
Risk passes to the Customer on the agreed delivery date, regardless of whether delivery was completed, where the delay was due to the Customer's unreadiness.
Company Delay
If RonYen Wellness fails to deliver by the agreed date, the Customer is entitled to a discount of 0.2% of the total order value per day of delay, up to a maximum of 5% of the total contract value. This is the Customer's sole remedy for late delivery.
Site Preparation
The Customer is responsible for ensuring the installation site meets all requirements, including structural load capacity. Ice baths and saunas are heavy when loaded, and the Customer must ensure the surface can safely support the full weight. Where there is doubt, a qualified structural engineer must confirm load capacity. RonYen Wellness accepts no liability for damage resulting from installation on an inadequate surface.
Warranty
Structural and electrical components carry the warranty periods set out in the product documentation. Warranty does not cover damage from improper installation, misuse, or lack of maintenance.
Limitation of Liability
RonYen Wellness's liability is limited to the purchase price of the product. We are not liable for consequential damages, installation costs, or third-party claims.
Health Disclaimer
Sauna and ice bath use may not be suitable for everyone. Customers should consult a physician before use if they have heart conditions, high blood pressure, are pregnant, or have other health concerns. RonYen Wellness is not liable for health issues arising from product use.
Force Majeure
We are not liable for delays or failure to perform due to circumstances beyond our reasonable control, including but not limited to natural disasters, material shortages, transportation disruptions, or government restrictions.
Dispute Resolution
Any disputes arising from this document shall be resolved through good-faith negotiation. If resolution cannot be reached, disputes shall be subject to the jurisdiction of Thai courts and governed by Thai law.
Outdoor and indoor cabins, barrels, cylinders, cube and modern designs, plus sauna-and-shower combos — from a compact one-person unit up to fourteen-person commercial rooms. Every model is made to order and customisable to your space. Browse saunas.
Red Cedar and Finnish Thermo Pine both handle heat and humidity beautifully — cedar for its aroma and natural rot resistance, thermo pine for its stability in wet conditions. Japanese Hinoki is our premium pick. Canadian Hemlock is excellent value for indoor cabins. We’ll match the timber to your budget, look 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 the same indoor-rated electric stone heaters — the difference is the exterior cladding and weatherproofing.
It depends on the internal volume of the cabin. As a guide: 4.5kW for 3–6 m³, 6kW for 5–8 m³, 9kW for 8–11 m³, 12kW for 11–15 m³, 15kW for 13–18 m³ and 18kW for 15–20 m³. Above 20 m³ takes two heaters. Up to and including 9kW runs on single phase; above that is three phase only, which in practice means anything from a six-person cabin upwards. We confirm the exact requirement in your quote so your electrician knows precisely what to install.
Both are food-grade and corrosion-resistant. 316 adds extra protection for coastal air and chlorinated water, so it’s the safer choice near the sea or beside a pool. 304 is excellent value everywhere else. We’ll recommend the right grade for your site. See ice baths.
Ice works to get started, but it melts fast in Thailand and gets expensive. A chiller holds a precise temperature day after day with no effort — it’s the easiest way to make cold therapy a daily habit rather than an occasional event.
Our chillers run from 0°C to 42°C, so the same unit chills in the hot season and heats in the cool one. Most people plunge between 3°C and 10°C. Beginners usually start around 12–15°C and work down over a few weeks.
Our chillers include filtration and ozone sanitation that keep the water fresh for weeks between changes: run the ozone for 30–60 minutes after each session with the lid on, and the hydrogen peroxide in the cleaning kit keeps the water clean in between (about 160 ml on a fresh 320 L fill, then ~50 ml a week, checked with a test strip). Both are safe on stainless, acrylic and PVC baths. We walk you through it at handover — it’s far less work than a pool.
Yes. Our brochures are on the site as downloads and we can email them to you. Because every sauna is made to order, the catalogue shows configurations and starting prices rather than a fixed range. Download the brochures.
The room dimensions, whether it is indoor or outdoor, how many people, and roughly where you are. If you have a floor plan, send that. From those four things we can quote accurately.
Yes, three ways. Come to the wellness garden and showroom in Ban Suan, Chonburi, ten minutes from Central Chonburi — there is a working sauna and ice baths you can use, by appointment. We hold finished samples of all four timbers. Or we will bring the samples to you: we travel anywhere in Thailand for a fee, and that fee comes off the price of your order when you buy. Book a consultation.
Yes. RonYen Wellness Co., Ltd is VAT registered and can issue full tax invoices. Ask us for the registration document if your accounts department needs it for approval.
Yes. We deliver to Koh Samui, Koh Phangan, Koh Tao, Koh Kood and Phuket regularly. Island delivery carries a supplement over mainland freight, quoted per job, and adds a few days. Tell us the island and we will price it with the quote rather than after.
We service Thailand and Laos. We are not set up for shipping further afield at the moment.
Mainland delivery is included in the price. Islands and remote provinces carry a supplement, quoted with your order.
Yes — we deliver right across Thailand by freight. Wherever you are, we’ll get it to you. Delivery details.
Occasionally, depending on the unit and where it is. Send us photographs of the heater, the control gear and the cabin and we will tell you honestly whether it is worth us coming or whether a local electrician can sort it for less.
Heater elements, stones, control panels and thermostats for the heaters we supply, held in Thailand. If you have another brand, tell us the model and we will say whether we can help.
Not currently.
Yes, for saunas in commercial operation. A room running twelve hours a day carries four to six times the load of a home installation, and scheduled servicing is what keeps it performing and keeps the warranty intact. Commercial servicing.
Yes — every sauna arrives in a sealed timber crate with the wall sections already built, and most assemble in a day with two or three people and the supplied instructions. No specialist tools needed. Prefer it done for you? Our team can handle the full install. Installation service.
Delivery to the spot, full assembly, levelling, fitting the heater, and a handover walkthrough so it’s ready to use the same day. It’s the easy option if you’d rather not build it yourself.
A firm, level base — a concrete pad, deck or paved area — plus a power point within reach for the heater. We send a simple prep checklist before delivery so everything’s ready when your sauna arrives.
The final hard-wire connection of the heater should be made by a licensed electrician — that part isn’t included, for safety and compliance. We supply the full heater specification and can recommend trusted local contractors.
Reserve online in a couple of minutes — pick a plan, a date and a time slot, and choose to pay online or on arrival. You’ll get a confirmation by email and text.
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, in a quiet private garden. A towel, flip-flops, a locker and your first drink come free with every visit. Explore the garden.
It’s in Chonburi, easily reached from Bangkok and Pattaya. We’re in a private gated community — when you arrive, look for the RonYen sign at the gate and we’ll open it for you. We text a reminder before your session so we’re ready and waiting.
Get a straight answer on what suits your space, budget and the Thai climate — free and with no pressure.
