Indoor Infrared Saunas

Indoor Infrared Saunas

Indoor infrared saunas with carbon or ceramic heating panels

Five ready-made models in three sizes, delivered anywhere in Thailand. Carbon panels warm your body directly at a gentle 25 to 67 degrees, so the cabin is ready in two to four minutes and there is no sauna room to build. The one and two person models plug into an ordinary 220V outlet. Choose Hemlock, Japanese Cedar or Red Cedar.

Buying guide
How is infrared different from a traditional sauna?

A traditional sauna heats the air to 80 to 100 degrees and that hot air heats you. Infrared barely heats the air at all. Carbon panels send warmth straight to your body at 25 to 67 degrees, so you reach a deep sweat in a gentler room and can comfortably stay in longer.

Does it need special wiring?

The one and two person models plug into an ordinary 220V socket with no electrical work. Only the four to five person model needs its own 16A circuit, connected by a licensed electrician. We check your board before delivery.

How long until it is ready to use?

Two to four minutes. The panels reach operating temperature quickly, so there is no long pre-heat to plan around. Most owners find this is why they use an infrared sauna far more often than a stove sauna.

Which timber should I choose?

Hemlock is the bright, even standard and the sharpest price. Japanese Cedar adds fragrance and warmth in the middle. Red Cedar gives the deepest colour and the fullest aroma. The sauna underneath is identical in all three.

Can I assemble it myself?

Yes. Each sauna arrives as six interlocking panels plus a glass front, with a stainless locking system, drawings and video guidance. Panels fit through normal doorways and up stairs. Professional installation by our team is available if you would rather not.

Is it genuinely low-EMF?

Yes. Carbon nanofiber paired with mica, with shielded wiring, insulation and heater placement engineered to keep EMF at the seat under 3 mG. All five models are certified to CE, ETL, SAA and PSE.

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.

Our saunas are made to order in China and Vietnam, in the same factories every time, to our own designs and specifications. We control the drawings, the timber grade and the quality standard on every order, and we have worked with these factories for years. Everything is then delivered and, if you would like, installed by our own team anywhere in Thailand. We would rather tell you that plainly than let you find out later.

Yes. Alongside traditional stone-heater saunas, we offer infrared cabins, which warm the body directly at a lower air temperature. They’re popular for smaller spaces and gentler sessions. We can talk you through which suits you in a free consultation.

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.
