Frequently Asked Questions
What size heater does this sauna require?
RonYen recommends a 6 kW heater for this cabin. The heater is specified separately at the time of order to suit your preferred heat-up time and electrical setup.
What are the electrical requirements for the 6 kW heater?
A 6 kW heater typically requires a dedicated 240 V circuit with an appropriate circuit breaker. Exact requirements depend on the heater unit selected, so we recommend confirming with a licensed electrician before installation.
Does this sauna genuinely fit two people?
Yes. The internal dimensions are 1424 × 1724 × 2060 mm, and the straight two-tier bench layout is designed to seat two adults. The upper bench provides the higher-heat position; the lower bench offers a cooler option.
How difficult is it to assemble, and are there any placement requirements?
The sauna arrives flat-packed for self-assembly and is designed to be put together without specialist tools. It should be placed on a flat, level surface indoors with enough clearance around the unit for ventilation and safe heater operation.
Can I pair this sauna with a RonYen ice bath?
Yes. RonYen makes both saunas and ice baths to order, so the two can be specified together to suit your available space and budget. Contact the team to discuss a paired setup.

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 soft-open on 30 July 2026 in Chonburi (with Founding Member pricing) and fully open on 4 September — and booking is open now, so you can reserve a session ahead. 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 six to eight 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.
