Steam & Oak Halla Twin Cold Plunge Tub
The Halla Twin is the only two-person cold plunge we sell — an oval thermowood tub with a moulded centre divider, so two people sit back to back rather than facing each other awkwardly across a small bath. It is the shape to choose if cold plunging is something you do with someone. Why the oval, and why the divider Most cold plunges are single-person, and the ones claiming two seats usually mean two people sharing one footwell. The Halla Twin has a moulded divider down the centre — each side is a proper seat with its own backrest and legroom. The oval shape is what makes that possible in a footprint that still fits a normal patio. A round tub big enough for two would take up considerably more ground. Clad in thermowood, heat-treated rather than chemically preserved. Timber steps included. Specification Capacity 2 people Shape Oval with moulded centre divider Cladding Thermowood Steps Timber, included Chiller Not fitted — retrofit available Filling it, and adding a chiller later Without a chiller you fill the tub and add ice. That costs nothing to run, and plenty of people are perfectly happy with it — a bag or two of ice brings 470 litres down quickly, and in a British winter the ambient temperature does much of the work for you. The honest limitation: in summer you will be buying ice regularly, and the water will not hold temperature for long. This tub is built to accept a chiller later. If you find yourself plunging more than once or twice a week, we sell the same tub with a chiller and filter unit fitted — and we can retrofit one to this tub rather than you needing to replace it. Water care Cold water still needs looking after, but far less than a hot tub. Without a chiller there is no filter, so you will change the water more often. You will also want a sanitiser — we stock tablets — and to change the water periodically depending on use. Cold water holds bacteria far less readily than hot, so maintenance is genuinely lighter than most people expect. It is not zero. Siting it A firm, level base. Water weighs a tonne per cubic metre — a 470 litre tub is nearly half a tonne before anyone gets in. Paving slabs, a concrete pad or a rated deck. Not soft ground, and not a lawn. Drainage. You will empty it periodically, so think about where several hundred litres will go. Power. None needed — this tub is self-fill. If you add a chiller later it will need an RCD-protected outdoor socket. Cold and heat together Contrast therapy — hot then cold — is the traditional Finnish pattern, and the reason a plunge tub next to a sauna gets used far more than one on its own. If you are building both, put them close together: the walk between them in a British winter is exactly the friction that stops people bothering. See our garden saunas and the off-grid gas heaters that let you put one at the far end of the garden without a trench. 2-year warranty Two years on the tub. Covers manufacturing defects and workmanship. Lead time — please ask before you order Lead times vary with stock and specification — anything from 2 to 12 weeks. Ask us before you commit and we will give you the real date. Delivery Delivered on a pallet. Heavy but manageable with two people. Images are manufacturer renders.
