Why it works
About this product
The Kaldera Plunge 80 trades capacity for footprint: at 70cm across, it sits in a bathroom corner or a hallway closet and packs down into a bag small enough for the boot of a car.
It uses the same 3-layer PVC-coated construction as the rest of the range, just scaled down, so you're not sacrificing durability for size. The single strap drain valve empties it in under three minutes.
Best suited to seated immersion rather than full-body submersion - ideal for renters, travellers, or anyone testing whether cold plunging fits their routine before committing to a larger tub.

Common questions
Everything you need to know
Can I fully submerge in it?
The Plunge 80 is best suited to seated immersion rather than full-body submersion. If you want shoulder-depth immersion, the Plunge 320 fits adults up to 6'4" - the 80 trades capacity for footprint.
Is it right for a small flat or for travel?
That's exactly what it's for. At 70cm across it sits in a bathroom corner or a hallway closet, and it packs down into a bag small enough for the boot of a car - ideal for renters and travellers.
How much is delivery, and how long does it take?
Typical transit is 5–10 working days from our UK and EU warehouses. Orders under £100 have a flat £4.95 (€5.95) tracked delivery fee, shown at checkout before you pay. You'll get a tracking number at dispatch.
Do I need a chiller, or can I just add ice?
Ice works fine for occasional plunges and is the cheapest way to start. If you want a set daily temperature, the Chill Core 300 is rated for tubs up to 350L, which covers the 80 comfortably - or the Starter Bundle pairs the two with the connecting hardware included.
Does it come with a lid?
No, a lid isn't included with the Plunge 80. It drains in under three minutes via the strap drain valve, so most owners empty or cover it between sessions.
Am I sacrificing durability for the smaller size?
No. It uses the same 3-layer PVC-coated construction as the rest of the range, just scaled down.
What if cold plunging turns out not to be for me?
You can return it within 30 days of delivery for a full refund, provided it's unused and in the condition you received it - that's the point of starting with the 80 before committing to a larger tub.
