Built in Hemlock

Every RonYen infrared sauna is built in Hemlock: pale, even-grained and comfortable to the touch at temperature. It keeps the room bright and even in tone, and it is the reason the range is priced the way it is.

03The red-light backrest

Red warmth at your back, and under your feet.

Infrared backrest board glowing warm red at night inside the 2-person red-light sauna
On the red-light saunas

Red warmth at your back, and under your feet.

Full-spectrum heaters run up the backrest and glow warm red the whole time the sauna runs, with a foot heater at floor level and 7-colour starlight in the ceiling you can set to the mood of the evening. It is the part people sit in front of and stop wanting to leave.

  • Full-spectrum backrest heaters, glowing warm in use
  • Foot heater at floor level
  • 7-colour starlight ceiling and reading lamp
  • Soft-touch controller with Bluetooth audio

RonYen presents this as a comfort and ambience feature, not clinical red-light therapy, and makes no medical claims for it.

04How infrared works

Body-direct heat.

A traditional sauna heats the air to 80–100°C, and that hot air heats you. An infrared sauna barely heats the air at all — the panels send warmth straight to your body.

The heaters reach operating temperature in about two to four minutes, so there is no long pre-heat to plan around. The result is a deep sweat in a gentler room: comfortable enough to sit in longer, and easy enough to use that most owners use it far more often than a stove sauna.

Infrared

Warms your body directly

Carbon nanofiber and mica panels emit mid- and far-infrared that passes through the air and warms you. The room never needs to be fierce for the sweat to be deep.

gentle air, warm body
Traditional

Heats the air first

A stove brings the whole room up to temperature, and the hot air passes that heat to your skin. It takes a long pre-heat, and it is fierce from the first minute you step in.

80–100°C air, everywhere you warm last
05Why RonYen infrared

A fixed range, not a building project.

Five saunas, fixed specs

Known spec and a known delivered price, with nothing to design from scratch. Choose a size and a timber, and that is the decision made.

Plugs into a standard Thai outlet

The 1- and 2-person saunas run from an ordinary 220V socket with no electrical work. The 4 person asks for its own 16A circuit.

Low-EMF carbon heaters

Carbon nanofiber paired with mica, with shielded wiring, insulation and heater placement engineered to hold EMF at the seat to 3–4 mG.

Arrives in protective timber crates

Six interlocking panels plus the glass front, rather than one unliftable box. Assemble it yourself, or have the RonYen team install it.

06What is inside every RonYen infrared sauna

07Delivery, assembly & install

Panels in, not one giant box.

Each sauna is assembled, powered up and inspected before it is packed flat into protective timber crates — so the heaters, lighting and controls are proven working before anything ships.

Spare roomBathroomBasementHome gymBedroom cornerVilla wellness room

Power, plainly

The 1- and 2-person saunas run from a standard 220V outlet. The 4 person draws about 14.5A, so it wants its own 16A circuit. We check your board before the delivery date, so nothing surprises anyone on the day.

1
Tested, then crated

Fully assembled and powered up at the factory, with heaters, lighting and controls checked before packing.

2
Carried in panel by panel

Six interlocking panels plus the glass front, so everything fits through normal doorways and up stairs. We plan the route with you before the truck is booked.

3
Self-assemble or we install

The stainless locking system makes self-assembly genuinely doable, with drawings and video guidance supplied — or take professional installation from our team.

4
Delivered and supported Thailand-wide

Bangkok, Phuket, Chiang Mai, Samui and everywhere between, with parts and service handled locally.

08For gyms, spas & wellness centres

The 4 person infrared sauna, built for daily commercial use.

It seats four guests per session, carries CE / ETL certification, and uses the same low-EMF carbon heaters as the home sizes, 3–4 mG at the seat. Fixed spec across units makes multi-site and multi-unit rollouts straightforward.

  • 4 guests per sessionWarm in two to four minutes, so sessions turn over through the day
  • 45 mm composite panels, stainless locking bucklesRigid and rattle-free under heavy use, and able to be moved or serviced
  • CE / ETL · EMF 3–4 mGCertified to international standards, with low-EMF construction for your compliance file

10Common questions

Before you ask us.

Does it need special wiring?

Not for the 1- and 2-person saunas: they draw roughly 6–9.5A and run from a standard 220V outlet. The 4 person draws 3200W, about 14.5A, so it wants its own 16A circuit — we check your board before the delivery date is set.

How hot does it get, and how long before it is ready?

Up to 67°C, adjustable from 25°C, with a 1–90 minute timer. The heaters reach operating temperature in about two to four minutes — far quicker than a traditional stove sauna, because infrared warms your body rather than heating the whole room first.

Why does an infrared sauna run cooler than a stove sauna?

Because it does not heat the air in order to heat you — the panels warm your body directly. At 25–67°C the sweat is still deep, and it is a temperature you can sit in longer and use more often.

Is it genuinely low-EMF?

Yes. Every sauna uses carbon nanofiber panels paired with mica, and the shielded wiring, insulation and heater placement are engineered to hold EMF at the seat to 3–4 mG.

How is it built — will it warp?

45 mm composite walls with a plywood core, specifically to resist the warping and cracking that timber alone suffers through heat cycles, locked together with stainless-steel buckles. Interior panels are a genuine 5–8 mm rather than the 3 mm budget makers use.

What timber is it?

Hemlock, on every model: pale, even-grained and the reason the range is priced the way it is.

Can I assemble it myself?

Yes. It ships as six interlocking panels plus the glass front, with drawings and video guidance, and two people can put it together. Professional installation from the RonYen team is there if you would rather skip it.

How does delivery work?

Each sauna is assembled and tested at the factory, then packed as panels in protective timber crates and delivered Thailand-wide. We confirm the schedule and check access with you in advance.

Where can I put it?

Any dry indoor space — spare room, bathroom, basement, home gym, bedroom corner or villa wellness room. Flat roof and a compact footprint, so it sits against a wall without a purpose-built sauna room.

What does the warranty cover?

One year on structure and electrical components. Parts and service are handled locally, and glass wall panels are removable, so a damaged panel is replaced on its own.

What does the red glow do?

On the 2-person red-light sauna the backrest board glows warm red while it runs, alongside 7-colour atmosphere lighting. RonYen presents it as ambience and comfort rather than therapy, and makes no medical claims for it.

Tell us the space. We will tell you the sauna.

Common questions

Everything you want to know about saunas & heaters

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.

See all questions

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.

See all questions

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.

See all questions

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.
