KeiCo Wellness Thermowood XL Ice Bath — DIY Flat Pack | 1000L Cold Plunge
Cold Therapy, Built Bigger.
The KeiCo Thermowood XL is a premium flat-pack cold plunge tub designed for straightforward self-assembly at home — no specialist tools, no contractors required. Crafted from kiln-treated Thermowood pine, it is naturally decay-resistant, low in moisture, and built to live outdoors year-round.
Choose the tub alone for a pure, eco-conscious cold plunge experience, or add the KeiCo PRO Chiller & Filter (1HP) for precision temperature control and crystal-clear water — in any season.
Designed for Real Use
The XL format is built for those who want a serious cold plunge setup at home — not a compromise. With a 1,000L capacity and 1,250mm diameter, it offers full-body upright immersion with room to settle and breathe.
The flat-pack supply means it can be delivered to most locations and assembled on-site, without the access constraints of a pre-built tub.
Thermowood Construction
Kiln-treated Thermowood pine is selected for its natural resistance to moisture and decay, its dimensional stability in outdoor conditions, and its clean, considered aesthetic. No chemical preservatives. No compromise on longevity.
Annual timber treatment is recommended to maintain the finish and maximise the lifespan of the structure.

FAQ's
What is the water capacity and how much space do I need?
The XL Thermowood Ice Bath is a larger-format cold plunge, so we recommend checking the product dimensions carefully before installation and allowing adequate clearance around the tub for safe access, filling, draining, and maintenance. For specific guidance on your space, contact the KeiCo team before purchase.
Do I need a chiller, or can I use ice?
The tub works well with ice for a straightforward manual cold plunge setup. For more consistent temperature control and easier day-to-day use, many customers choose to pair their ice bath with the optional KeiCo PRO Chiller & Filter — available as an upgrade at the point of order.
How do I maintain the water between sessions?
Water maintenance will depend on frequency of use and whether a filtration system is fitted. We recommend showering before use, keeping the tub covered when not in use, removing debris regularly, and refreshing or treating the water as required. The optional PRO Chiller & Filter supports cleaner water between sessions through integrated filtration.
Can the XL Thermowood Ice Bath be used indoors?
It may be suitable for indoor use where the space has appropriate flooring, drainage, and ventilation. Because the filled tub is heavy, the floor must be capable of safely supporting the load. We recommend confirming suitability with a structural professional before indoor installation.
What base or surface does the ice bath need?
The ice bath should be placed on a solid, level, and load-bearing surface. Suitable options include concrete, paving slabs, or reinforced decking. The base should remain stable when the tub is filled and allow safe access for use, draining, and maintenance.
