Frequently Asked Questions
How is an infrared sauna different from a traditional sauna?
Infrared panels warm your body directly rather than heating the air, so it runs at a gentler 25–67°C and warms up in a few minutes on a standard power supply.
What power supply does it need?
The 1- and 2-person models run from a standard wall outlet. The 4–5 person model needs a dedicated 16A circuit.
Do I need professional installation?
Assembly is straightforward and two people can do it, with drawings and video guidance supplied. Professional installation from the RonYen team is available if you would rather it was handled.
What timbers can I choose?
Hemlock (standard), Japanese Cedar (mid) and Red Cedar (premium). Each timber is priced separately, and the price shown updates as you choose.
Is the red glow a therapy feature?
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.
What does the warranty cover?
One year on the structure and electrical components.

Japanese Cedar

Warm honey tone with a soft straight grain and a gentle natural aroma when heated. A step up in character from Hemlock.

Common questions

Everything you want to know about saunas & heaters

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.
