Icetubs is a Dutch cold and hot plunge maker founded in Amsterdam in 2020. Its founder spent a decade building wood-fired hot tubs in Europe before turning to cold therapy, after repeated requests for a heaterless tub led him to test one himself.

That manufacturing background shows in the build. Each tub pairs furniture-grade Thermowood with a stainless steel or fiberglass interior, run by the brand's own Icetubs Engine, a single unit that both chills and heats and is set from an app or an on-tub panel. A three-stage filtration system with a built-in ozonator keeps the water clear without chemicals.

Ellara carries Icetubs for that combination of engineering and design, and curates which models make sense for a home setup before they reach this page.
