The go-to indoor sauna timber: stable, clean and light, with a soft aroma. It keeps the room feeling bright and even in tone.
Available on every size — priced from ฿88,999

A step up in warmth and character from Hemlock, with a soft natural fragrance that comes forward as the sauna heats. The middle option in both tone and character.

The pick for a sauna that is part of the room rather than tucked in a corner — deepest colour and the fullest aroma. Structure, heaters and controls are identical.
Available on every size — priced from ฿104,800

The backrest glows the whole time it runs — an enveloping warmth across the back and shoulders — with 7-colour atmosphere lighting you can set to the mood of the evening. It is the part people sit in front of and stop wanting to leave.
RonYen presents this as a comfort and ambience feature, not clinical red-light therapy, and makes no medical claims for it.
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.
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.
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.
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.
The 1- and 2-person saunas run from an ordinary 220V socket with no electrical work. The 4–5 person asks for its own 16A circuit.
Carbon nanofiber paired with mica, with shielded wiring, insulation and heater placement engineered to keep EMF at the seat under 3 mG.
Six interlocking panels plus the glass front, rather than one unliftable box. Assemble it yourself, or have the RonYen team install it.

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.
The 1- and 2-person saunas run from a standard 220V outlet. The 4–5 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.
Fully assembled and powered up at the factory, with heaters, lighting and controls checked before packing.
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.
The stainless locking system makes self-assembly genuinely doable, with drawings and video guidance supplied — or take professional installation from our team.
Bangkok, Phuket, Chiang Mai, Samui and everywhere between, with parts and service handled locally.
It seats four to five guests per session, carries CE / ETL / SAA / PSE certification, and uses the same low-EMF carbon heaters as the home sizes. Fixed spec across units makes multi-site and multi-unit rollouts straightforward.

Not for the 1- and 2-person saunas: they draw roughly 6–9.5A and run from a standard 220V outlet. The 4–5 person draws 3200W, about 14.5A, so it wants its own 16A circuit — we check your board before the delivery date is set.
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.
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.
Yes. Every sauna uses carbon nanofiber panels paired with mica, and the shielded wiring, insulation and heater placement are engineered to keep EMF at the seat under 3 mG, per the manufacturer's published spec.
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.
Hemlock for a clean, stable, cost-effective sauna with a light tone. Japanese Cedar for more warmth and a soft natural fragrance. Red Cedar for the warmest tone and the richest aroma. Structure, heaters and controls are identical across all three.
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.
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.
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.
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.
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.
A photo of the corner you have in mind is usually enough. We come back with the size that fits, the delivered price, and the soonest it can be in.
