Electronics: 1 year warranty on all electronic components
Elements and body: 1 year warranty on material and workmanship
Warranty does not cover misuse, modifications, incorrect installation, or normal wear of the heating elements.
Pouring Water on Your Heater
Pour water slowly onto the stones using a ladle, and avoid tipping a large volume in one pour. Read our guide on how to pour water on sauna rocks without destroying your heater →
Stones
Rearrange the stones once or twice a year. They settle and pack down with use, which restricts airflow and shortens element life. Replace any that have crumbled.
Replacement Heater Elements
Elements typically need replacement every few years depending on use. Individual elements can be replaced rather than the whole heater, and replacements are available from RonYen.
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.
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.
