Terms & Conditions

RETURNS, REFUNDS AND EXCHANGES

Updated: 26 Aug, 2026

Returns, refunds and exchanges on equipment are governed by our Returns Policy,
which forms part of these Terms. See ronyen.com/returns-policy

In summary, you have 7 days from delivery to notify us of a return on a stock
item in resalable condition, and we refund within 15 days of receiving it back.
Made-to-order and custom items cannot be returned once production has begun.
Faulty or misdescribed goods are repaired, replaced or refunded at our cost.

Where the Returns Policy and these Terms differ, the Returns Policy applies to
returns, refunds and exchanges.

CUSTOM AND MADE TO ORDER GOODS

A custom order is any sauna, ice bath, cabin or chiller built to dimensions,
timber, steel grade, colour or configuration you have specified, and any item
described at the point of sale as made to order.

We will confirm your specification in writing before production begins. That
confirmation is your final opportunity to change or cancel the order without
charge.

Once production begins, the order cannot be cancelled or returned other than
for fault. If you cancel after production begins, we will charge for materials
committed and work completed to that point, and refund the balance.

CANCELLATION BEFORE DISPATCH

Stock items may be cancelled at any time before dispatch for a full refund,
including any delivery charge paid.

Custom items are covered by the clause above.

PRICING AND AVAILABILITY

Prices shown on the website are in Thai Baht and include VAT where applicable.

We may correct pricing errors at any time before we accept an order. Where a
price is corrected after you have placed an order but before we accept it, we
will contact you and you may proceed at the corrected price or cancel for a
full refund.

Stock availability is not guaranteed until we accept an order.

DELIVERY AND RISK

Delivery timeframes given on product pages and in quotes are estimates, not
guarantees.

Risk in the goods passes to you on delivery. Inspect your delivery on arrival
and photograph any damage to the outer packaging before it is discarded, as
freight damage claims depend on that evidence.

Delivery terms are set out at ronyen.com/our-services/delivery

INSTALLATION

Installation is an optional add-on service and is quoted separately.

Where you install yourself or engage a third party, we are not responsible for
faults arising from that installation, and installation faults are not covered
by the product warranty.

WARRANTY

Each product carries a manufacturer warranty. Duration and cover are stated on
the product page under Warranty.

The warranty covers manufacturing defects. It does not cover wear and tear,
damage from misuse, incorrect installation, water chemistry that falls outside
the ranges we specify, or timber movement consistent with normal seasoning in
a tropical climate.

Warranty rights are in addition to your rights under Thai consumer law.

WELLNESS GARDEN BOOKINGS

Sessions at the Wellness Garden are booked in advance. We do not accept
walk-ins.

Reschedule or cancel at least [24 / 48] hours before your session for a full
refund or a credit. Inside that window, [state your position].

If we cancel a session, you receive a full refund or a credit, whichever you
prefer.

Session bookings are a service and are not covered by our Returns Policy.

GOVERNING LAW

These Terms are governed by the laws of Thailand, and the Thai courts have
jurisdiction over any dispute arising from them.

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.

Both are food-grade and corrosion-resistant. 316 adds extra protection for coastal air and chlorinated water, so it’s the safer choice near the sea or beside a pool. 304 is excellent value everywhere else. We’ll recommend the right grade for your site. See ice baths.

Ice works to get started, but it melts fast in Thailand and gets expensive. A chiller holds a precise temperature day after day with no effort — it’s the easiest way to make cold therapy a daily habit rather than an occasional event.

Our chillers run from 0°C to 42°C, so the same unit chills in the hot season and heats in the cool one. Most people plunge between 3°C and 10°C. Beginners usually start around 12–15°C and work down over a few weeks.

Our chillers include filtration and ozone sanitation that keep the water fresh for weeks between changes: run the ozone for 30–60 minutes after each session with the lid on, and the hydrogen peroxide in the cleaning kit keeps the water clean in between (about 160 ml on a fresh 320 L fill, then ~50 ml a week, checked with a test strip). Both are safe on stainless, acrylic and PVC baths. We walk you through it at handover — it’s far less work than a pool.

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.

Yes. We deliver to Koh Samui, Koh Phangan, Koh Tao, Koh Kood and Phuket regularly. Island delivery carries a supplement over mainland freight, quoted per job, and adds a few days. Tell us the island and we will price it with the quote rather than after.

We service Thailand and Laos. We are not set up for shipping further afield at the moment.

Mainland delivery is included in the price. Islands and remote provinces carry a supplement, quoted with your order.

Yes — we deliver right across Thailand by freight. Wherever you are, we’ll get it to you. Delivery details.

See all questions

Occasionally, depending on the unit and where it is. Send us photographs of the heater, the control gear and the cabin and we will tell you honestly whether it is worth us coming or whether a local electrician can sort it for less.

Heater elements, stones, control panels and thermostats for the heaters we supply, held in Thailand. If you have another brand, tell us the model and we will say whether we can help.

Not currently.

Yes, for saunas in commercial operation. A room running twelve hours a day carries four to six times the load of a home installation, and scheduled servicing is what keeps it performing and keeps the warranty intact. Commercial servicing.

See all questions

Yes — every sauna arrives in a sealed timber crate with the wall sections already built, and most assemble in a day with two or three people and the supplied instructions. No specialist tools needed. Prefer it done for you? Our team can handle the full install. Installation service.

Delivery to the spot, full assembly, levelling, fitting the heater, and a handover walkthrough so it’s ready to use the same day. It’s the easy option if you’d rather not build it yourself.

A firm, level base — a concrete pad, deck or paved area — plus a power point within reach for the heater. We send a simple prep checklist before delivery so everything’s ready when your sauna arrives.

The final hard-wire connection of the heater should be made by a licensed electrician — that part isn’t included, for safety and compliance. We supply the full heater specification and can recommend trusted local contractors.

Reserve online in a couple of minutes — pick a plan, a date and a time slot, and choose to pay online or on arrival. You’ll get a confirmation by email and text.

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, in a quiet private garden. A towel, flip-flops, a locker and your first drink come free with every visit. Explore the garden.

It’s in Chonburi, easily reached from Bangkok and Pattaya. We’re in a private gated community — when you arrive, look for the RonYen sign at the gate and we’ll open it for you. We text a reminder before your session so we’re ready and waiting.
