Built from military-grade drop-stitch PVC, this large octagonal inflatable tub inflates to a rigid, hard-sided structure that holds its shape under the full weight and pressure of a deep plunge. The walls stiffen in the same way as a stand-up paddleboard — no flex or wobble once inflated to the correct PSI. The outer diameter is 200 cm, inner diameter 180 cm, with 80 cm of wall depth: enough for a comfortable seated full-body immersion for up to 4 people simultaneously.

Pre-drilled water inlet and outlet ports with watertight caps let you run the tub with manual ice straight away, then connect an electric chiller later without any modification. The insulated thermal lid clips shut with safety buckles to hold the temperature between sessions. When not in use, the entire setup deflates and packs into the included heavy-duty carry bag.
The bundled chiller cools and heats water across a 0 °C–42 °C range and features a 7-inch full-colour LCD touchscreen, Wi-Fi control via a smartphone app (iOS and Android), built-in ozone disinfection (up to 50 mg/hr), and IPX4 weatherproofing for outdoor placement. Dual precision filters intercept 99.9% of particulate matter and detach easily for servicing. Four load-bearing castors with 360° swivel and brake lock make repositioning straightforward.
Built to order — allow 3–6 weeks from deposit to delivery. The deposit is refundable within 7 days of placement.
Delivery is kerbside unless otherwise arranged. The deflated tub ships in a carry bag and the chiller unit ships boxed; both are manageable with two people. Ensure clear vehicle access to the installation site.
Contact us before ordering if access is restricted (stairs, narrow gates, upper floors) so we can advise on handling.
There is no installation. That is the point of an inflatable.
Setting up
Unroll it, inflate it with the pump supplied, and fill it. Fifteen minutes from box
to water. Take it down as quickly when you want the space back.
Base
Any flat surface that can take the weight. Grass, decking, tile, concrete. Clear
anything sharp from underneath first — a stone under an inflatable is the one
failure mode that matters.
Weight when full
Water is a kilogram a litre, and an inflatable holds more than it looks like it
does. Check the capacity in the specifications. On a balcony or a roof terrace,
check the loading before you fill it, because an inflatable gives you no warning
that it is heavy until it already is.
Draining and storage
Drain fully, dry it completely, then fold it. Storing an inflatable damp is how
they grow things and how the material degrades. Give it a day in the shade to dry
rather than folding it wet.
The chiller
The chiller is a separate unit that sits beside the bath, connected with the hoses
supplied. Inlet and outlet are 1/2 inch on both.
It needs its own dedicated circuit: 220-240 V single phase, a Type C breaker, and
its own 30 mA RCBO. Do not run it from an extension lead or share the circuit. A
compressor on a shared socket circuit trips it, and an outdoor extension lead
carrying a compressor is a genuine hazard.
Allow around 500 mm clear behind the chiller for airflow and keep it out of direct
afternoon sun.
Professional installation is not required and is not offered for this product.
If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.
Warranty details were not explicitly stated in the supplied material. Please confirm coverage period and terms before publishing.
- Rinse the interior of the tub with clean water after each use and allow it to dry before deflating or fitting the lid.
- The chiller's dual precision filters are detachable — inspect them every 2–4 weeks and rinse or replace as needed. A spare filter element and filter bottle wrench are included.
- The built-in ozone disinfection system (up to 50 mg/hr) reduces the need for chemical sanitisers; avoid using harsh bleach-based products that may degrade the PVC.
- Wipe down the chiller casing with a damp cloth; do not use abrasive cleaners on the stainless steel heat-dissipation panel.
- Check the waterproof tape seals on hose connections periodically and replace if signs of wear appear.
- When deflating for storage, ensure all water is drained via the bottom drain valve before packing into the carry bag.
- Store the deflated tub away from direct UV exposure and sharp objects to protect the PVC.
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.
Built to order
Every bath is made after the order is placed. Because nothing is built until you
order it, made-to-order baths cannot be returned or exchanged for change of mind.
Anything faulty is covered under warranty.
Deposit and balance
A deposit confirms the order and starts production. The balance falls due before
dispatch. Your quote states both figures.
Prices
Quoted prices hold for 30 days. They include 7% VAT and delivery within Thailand.
They exclude electrical work, structural certification, crane hire and any site
preparation.
Site readiness
The base, the access route and the power supply are the customer's responsibility
and need to be ready on the delivery date. Where a bath is going onto a roof, a
balcony, a deck or any suspended floor, written structural sign-off is required
before delivery.
Changes
Specification changes are possible before production starts. Once the build is
under way a change may not be possible, and where it is, it may carry a cost.
Colour and grain
Timber is a natural material. Colour, grain and figure vary between boards and
between baths, and timber left outdoors changes colour over time. Photographs are
representative rather than exact.
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.
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.
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.
Get a straight answer on what suits your space, budget and the Thai climate — free and with no pressure.
