This circular cold plunge is built for daily use — not a plastic tub or an inflatable novelty. The red cedar exterior is selected for grain consistency and natural oils that resist moisture and weathering, making it well-suited to both indoor and outdoor installation in a tropical climate. The 304-grade stainless steel interior is fully hygienic and corrosion-resistant, and it retains heat longer than plastic or fibreglass alternatives.

Available in three sizes to suit solo plungers through to group setups, the circular form allows for natural full-immersion positioning. Heavy-duty stainless steel bands and hardware hold the structure together and add visual contrast to the warm cedar slats. A black vinyl lid is included to retain cold temperatures between sessions.
The bath is compatible with a dedicated chiller unit for precise, consistent temperature control or with ice. It suits both residential and commercial installations and can be positioned on any load-bearing surface, indoors or outdoors.
The bath arrives partially assembled and requires positioning on a flat, level, load-bearing surface before final assembly and filling. No specialist trades are required for basic installation — two people can manage placement and setup.
A 220–240V 60Hz power outlet is required within reach of the chiller connection if a chiller unit is being used. If a chiller is installed, follow the chiller unit's specific electrical connection instructions; a dedicated circuit may be required depending on local electrical codes.
The drain connection should be positioned to allow gravity drainage or pump-out access. Confirm floor drainage or a suitable runoff point before finalising the installation location. For rooftop or elevated deck installations, verify the structural load capacity before filling — a full bath can weigh several hundred kilograms.
If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.
Structural components are covered against manufacturing defects. Please confirm warranty duration and specific coverage terms with the supplier before listing.
Cedar exterior
Wipe down the cedar slats with a damp cloth after each use. Do not use harsh chemical cleaners or pressure washers directly on the timber. Allow the exterior to dry naturally between sessions — avoid leaving standing water pooled at the base for extended periods. The natural oils in red cedar provide inherent moisture resistance; no sealing or oiling is required under normal use, though an annual light application of a food-safe timber oil can help maintain appearance.
Stainless steel interior
Rinse the 316-grade stainless steel interior with clean water after each session. For periodic deep cleaning, use a mild, non-abrasive stainless steel cleaner and rinse thoroughly before refilling. Avoid bleach-based products, which can compromise the steel's surface over time.
Water maintenance
If the bath is kept filled, change the water regularly — weekly for high-use installations, fortnightly for light use. A compatible chiller unit with built-in filtration will extend water change intervals. pH-neutral water treatment tablets are recommended for shared or commercial use.
Hardware
Inspect the stainless steel bands and fasteners every three to six months for any signs of corrosion or loosening and tighten as needed. The hardware is 316-grade and suited to outdoor environments, but periodic checks will extend service life.
Outdoor and indoor cabins, barrels, cylinders and sauna + shower combos — from a compact one-person unit up to ten-person commercial rooms, all customisable to your space. Browse saunas.
Western Red Cedar and Finnish Thermo Pine both handle heat and humidity beautifully; Hinoki is our premium pick. We’ll match the timber to your budget 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 indoor-rated electric heaters.
Most home saunas run on a dedicated single- or three-phase circuit sized to the heater. We’ll confirm the exact electrical requirement in your quote.
Both are food-grade and corrosion-resistant; 316 adds extra protection for coastal and chlorinated environments. We recommend the right grade for your site. See ice baths.
Ice works to get started, but a chiller holds a precise temperature day after day with no effort — the easiest way to make cold therapy a daily habit.
Our chillers take the water down to around 3°C and hold it there. Most people plunge between 3–10°C depending on experience.
A built-in filtration and sanitation cycle keeps the water fresh for weeks. We’ll walk you through simple water care at handover.
We soft-open on 30 July 2026 in Chonburi (with Founding Member pricing) and fully open on 4 September — and booking is open now, so you can reserve a session ahead. Book a visit.
