Inflatable, timber and stainless steel ice baths, from a starter you can set up this weekend to a custom build in the size and steel grade you choose. Every bath runs on ice alone, or pairs with a chiller when you want the cold held for you.
304 is fine for most indoor and covered outdoor installations. 316 is recommended for coastal or fully exposed sites for better corrosion resistance against salt air.
Yes — standalone tubs work with ice and a thermometer for traditional cold therapy. A chiller adds convenience and precise temperature control so the bath is ready whenever you are.
Single-person baths hold roughly 250–320 litres; two-person around 450–550. With a chiller and a cover, the same water stays clean for weeks with simple maintenance.
Our chillers pair with our baths and most third-party tubs. We'll match the chiller capacity to your bath volume — tell us your setup and we'll confirm.
Yes — delivered across Thailand, free. Professional installation is available; standalone tubs without a chiller can usually be self-installed.
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.
Stainless steel tubs, timber-clad baths in cedar and thermo pine, acrylic plunge baths, barrel baths, and all-in-one baths with the chiller built in. Sizes run from single-person plunge tubs to larger baths for two or for commercial recovery rooms.
It comes down to how much water the bath holds and where it sits. Outdoors in the shade: the 1.0HP up to 600 litres, the 1.5HP up to 1,000 litres, the 2.0HP up to 1,400 litres. Indoors in an air-conditioned room: the 1.0HP up to 750 litres, the 1.5HP up to 1,200 litres, the 2.0HP up to 1,700 litres. In full sun, shade the bath and the chiller, or go one size up. Above 1,400 litres outdoors, talk to us and we will size it for you. Each ice bath page shows how much water it holds and offers only the chillers that suit it.
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.
