Something New Is Taking Shape in Our Workshop

We have been building custom saunas and ice baths in Thailand since 2020, and we know our customers well by now. One question keeps coming up: "Is there a faster, easier way to get the cold exposure without filling and chilling a full tub?"

The answer is yes — and we are currently developing it.

Sisu Sauna is building an ice shower designed for both domestic and commercial use, hand-built right here in Thailand. It is not yet available to order, but we wanted to share what we are working on and why we think it fills a genuine gap in the market.

Ice Shower vs Ice Bath: What Is the Practical Difference?

Both deliver cold-water exposure and the well-documented benefits that come with it — reduced inflammation, improved circulation, a sharp lift in mood and alertness, and faster recovery after training. The experience, however, is quite different in practice.

Time to Ready

This is where the ice shower stands apart. A traditional ice bath — whether you are using a tub with a chiller or loading it with ice — takes roughly 3 hours or more to reach a proper cold-plunge temperature. You need to plan ahead, and in a commercial setting like a gym, spa or wellness studio, that window of downtime has a real cost.

An ice shower, by contrast, is ready in approximately 15 minutes. Turn it on, do your sauna session, and step straight into cold water at the temperature you want. No waiting, no planning around a three-hour cool-down cycle.

Space and Installation

A full ice bath needs a dedicated footprint, structural support for the loaded weight of water, and space for a chiller unit beside it. An ice shower has a much smaller floor plan — practical for apartments, compact wellness studios, or any space where a plunge tub simply will not fit.

The Experience Itself

Immersion in cold water and a cold shower are not identical physiologically, and some people genuinely find one more tolerable than the other. A shower allows the user to control the intensity moment to moment — stepping in gradually, adjusting the flow — which can make cold exposure more accessible for beginners or for clients in a commercial setting who are new to the practice.

An ice bath, on the other hand, delivers full-body immersion and is the format used in most of the well-known research on cold-water therapy. For serious recovery work and hot-cold contrast protocols paired with a sauna, immersion remains the gold standard. Both tools have their place.

Built for Thailand's Market — and the World

Everything we make at Sisu Sauna is built with Thailand's climate, voltage, and conditions in mind. Our ice shower is being developed the same way — designed to work reliably in high-ambient-temperature environments, built from materials that handle humidity, and sized for the spaces our customers actually have.

We are targeting both domestic buyers — homeowners who want a complete hot-cold wellness setup at home — and commercial operators: gyms, Muay Thai camps, hotel spas, wellness studios, and recovery centres where fast turnaround and consistent performance matter every single day.
