Why it works
About this product
The Starter Bundle pairs a compact tub with the chiller sized to match it, so you're not guessing at compatibility. It's the setup we point most first-time buyers toward.
The box includes the Plunge 80, the Chill Core 300, and a Floating Digital Thermometer - the thermometer's included free, along with the hoses and fittings needed to connect the tub and chiller. Bought separately, these three come to £680.99; as a bundle it's £649, a saving of £31.99.
Everything ships together so setup is a single afternoon rather than three separate deliveries.

Common questions
Everything you need to know
What exactly is in the box?
The Plunge 80 tub, the Chill Core 300 chiller, and a Floating Digital Thermometer - the thermometer's included free, along with the hoses and fittings needed to connect the tub and chiller.
How much do I actually save?
Bought separately, these three come to £680.99; as a bundle it's £649 - a saving of £31.99, plus the thermometer and connecting hardware are already matched to the set.
Is the chiller the right size for the tub?
Yes, that's the point of the bundle. The Chill Core 300 is rated for tubs up to 350L, which covers the 80L Plunge comfortably, so you're not guessing at compatibility.
Does it all arrive together?
Yes. Everything ships together so setup is a single afternoon rather than three separate deliveries. Typical transit is 5–10 working days, with free tracked delivery (free on all orders over £100).
Is this the right setup for a first-time buyer?
It's the setup we point most first-time buyers toward: a compact tub with the chiller sized to match it, so you can hold a set temperature from day one instead of hauling ice.
What warranty and returns apply?
The chiller carries a 2-year warranty, and the standard 30-day returns policy applies: return unused items within 30 days of delivery for a full refund.

Rachel Tanaka-Smith
Buying the bundle took all the guesswork out of sizing a chiller to the tub. Arrived together, set up in an afternoon, no compatibility issues.
Ollie Petursson
Cheaper than buying the tub and chiller separately and I didn't have to think about which chiller size to pick. Exactly what a first-timer needs.
Grace Adebayo
Great value bundle. Instructions could be clearer on hose routing but customer support answered quickly when I asked.
