02 Why inflatable

Cold therapy, minus the renovation.

A hard-shell plunge means concrete, plumbing, an electrician and a five-figure bill. This doesn’t. It arrives in a box and packs back into one.

  • Concrete pad poured Sits on any flat surface
  • Plumbed in permanently Two hoses, no plumbing
  • Install crew on site You set it up yourself
  • Five-figure spend Under ฿70,000, complete

03 The chiller upgrade

Set it cold. Keep it cold. No more ice runs.

The optional chiller cools, filters, and circulates your water automatically — so it’s clean, evenly cold, and ready whenever you are. No bags of ice, no hauling, no daily top-ups.

CoolHolds your set temperature, as cold as 3°C (and lower if you really want it). Set it once and forget it.
FilterWith a chiller, built-in filtration keeps your water clean for weeks. Without one, you’re draining and refilling every few days.
CirculateConstant circulation keeps the water evenly cold and fresh, every single plunge.

Cheaper than bags of ice within months — see the real maths ↓

Not ready for a chiller? Every ice bath works perfectly with ice alone — add a chiller whenever you like.

04 Setup

Set up in minutes — no tools, no plumber.

From the box to your first plunge in no time. No trades, no permanent fixtures, nothing drilled or plumbed.

Step 01Unfold & inflatePump included. Just a few minutes.
Step 02Fill with waterStraight from a garden hose.
Step 03Cool it downSwitch on the chiller, or add ice for bath-only.
Step 04PlungeThat’s it. No plumbing, no tools, no installer.

No special skills and no trades required — if you can inflate an air mattress, you can set this up.

05 Why start here

The honest entry into cold plunging.

Here’s the truth most sellers won’t tell you: you shouldn’t drop two hundred thousand baht on a permanent cold plunge before you know you’ll actually use it. Start here instead.

Start for a fraction of the cost

A built-in plunge or a custom steel bath is a serious investment. An inflatable gets you the exact same cold water, the exact same benefits, for a fraction of the price. Same shock, same recovery, same morning ritual — without the renovation budget.

No commitment you’ll regret

Cold plunging isn’t for everyone, and that’s fine. Starting with an inflatable means finding out without the risk. Love it, and you’ve found a habit that’s hard to give up. Decide it’s not for you, and you haven’t sunk a fortune into concrete.

When you’re ready for more, we build that too

Plenty of our customers start here and later move up to a permanent steel bath or a full sauna setup. There’s no rush — and no sense starting at the top before you know what you want.

Set up as easily as it comes down

No trades, no permanent fixtures, nothing you can’t undo. If you move, it moves. If you want the space back, it packs away.

Worst case, you’ve spent ฿17,000 finding out. Best case, you’ve found the thing that changes your mornings.

11 FAQ

Questions, answered straight.

How cold does the ice bath get?

With a chiller, as cold as 3°C — and lower if you really want it, though almost no one plunges below 3°. Most people sit between 3° and 15°. Bath-only (no chiller), you control the temperature with how much ice you add.

Do I need the chiller, or can I just use ice?

You can absolutely start with ice — every bath works perfectly bath-only. The chiller just removes the chore: it holds your set temperature automatically, so no daily ice runs. Most people start with ice and add a chiller once they’re hooked. Within a few months, a chiller usually works out cheaper than buying bags of ice.

Will an inflatable ice bath pop or leak?

No. These use drop-stitch construction — the same tech as stand-up paddleboards — so the walls are firm and hold their shape like a solid tub. You can lean on the rim and sit in it properly. It won’t sag, wobble, or burst under normal use.

How long does delivery take?

1 week. We keep you updated on progress and your delivery date, and delivery is free anywhere in Thailand. Your balance is only due once your order is ready to ship.

How do I pay — and is it safe?

You pay a 50% deposit to secure your order and production slot, then the balance before it ships. We accept Visa, Mastercard, and direct Thai bank transfer, over a secure encrypted checkout.

Where can I put it? I rent / live in a condo.

Anywhere flat with access to water — a balcony, terrace, courtyard, or even a spare bathroom corner. There’s no plumbing and nothing permanent, so there’s no renovation and no landlord conversation needed. If you move, it moves with you.

How do I set it up?

Unfold it, inflate it with the included pump, fill it from a garden hose, and cool it down. No tools, no plumber, no trades. If you can inflate an air mattress, you can set this up.

How do I keep the water clean?

With a chiller, the built-in filtration keeps the water clean for weeks. Without a chiller, you’ll drain and refill every few days, like any ice bath.

It’s 35° out there. Plunge at 3°.

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. We walk you through simple water care at handover — it’s far less work than a pool.

See all questions

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.

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.
