Cold plunge tubs, welded from one sheet of stainless.

Seamless welded 304 or 316 stainless plunge tubs and ice baths, insulated and built to the size you actually want — not the size a shipping container allowed. Chiller-ready, drain and overflow fitted, and no plastic liner to crack or stain.

The range

Built for the space, not the shipping box.

Most plunge tubs are moulded plastic or a barrel in a fixed size. A welded stainless tub can be any length, depth or shape — fitted into a deck, dropped into a bench, or free-standing on legs.

Free-standing plunge tubs

Insulated stainless tubs on a welded base or legs, with a step, seat ledge and lid.

Deck-recessed tubs

Tubs built to drop into a timber deck or platform, with a flange that sits flush and a removable lid.

Ice baths & recovery tubs

Simple uninsulated tubs for gyms, clubs and recovery rooms, with a big drain and a rolling frame.

Plunge & spa combinations

A cold tub alongside a hot tub or spa, sharing a deck surround, plant space and plumbing run.

Off-the-shelf plunge tubs are usually sold as a package with a chiller. Here the tub is priced on its own, so you can pair it with whatever chiller and filtration you want — or none at all.

Questions

Common questions about stainless steel cold plunge tubs and ice baths.

Does the price include a chiller?

No. The tub is priced on its own so you can choose your own chiller, filtration and sanitiser, or run it on ice. We fit the ports, drain and overflow to suit the unit you pick, and can install a supplied chiller.

304 or 316 stainless?

304 is fine indoors and in most inland situations. 316 is the choice within a few kilometres of the coast, or if the water is heavily chlorinated or salt sanitised.

Can it be built into a deck?

Yes. Deck-recessed tubs are built with a flange that sits flush with the decking, so only the rim and lid show. We work from your deck framing dimensions.

How long does one take?

A straightforward tub is usually a few weeks from confirmed drawings. Insulated and clad tubs with a plant enclosure take longer. We give a date with the quote.
