Why it works
About this product
The Starter Bundle pairs our lowest-priced tub with our entry-level chiller, plus a thermometer so you can check the water before you get in.
It includes the Plunge 80 (80 × 75cm), the Chill Core 300 (1/3HP, rated by its supplier for up to 300 litres and about 15°C) and a Wireless Floating Thermometer. Bought separately, these three come to £697.00; as a bundle it's £649, a saving of £48.00.
The items come from different suppliers, so they may arrive as separate parcels, each tracked. Fill the tub below 300 litres to stay within the chiller's rating.

Common questions
Everything you need to know
What exactly is in the bundle?
The Plunge 80 tub, the Chill Core 300 chiller and a Wireless Floating Thermometer. The chiller supplier doesn't list hoses or fittings, so contact us before ordering if you need them confirmed.
How much do I actually save?
Bought separately, these three come to £697.00; as a bundle it's £649 - a saving of £48.00.
Is the chiller the right size for the tub?
The Chill Core 300 is rated by its supplier for up to 300 litres, and the Plunge 80 measures 80 × 75cm, so fill it below 300 litres. The 300 cools to about 15°C; if you want colder water, the Performance Bundle's Chill Core 500 is rated to roughly 4–9°C.
Does it all arrive together?
Not always. The items come from different suppliers, so they may arrive as separate parcels, each with its own tracking number. Delivery is free on this order, and delivery times are on our shipping page.
Is this the right setup for a first-time buyer?
It's the lowest-priced way to a chilled tub: a sit-in tub with an entry-level chiller, so you can hold a set temperature instead of hauling ice. If you live somewhere warm or want water below about 15°C, look at the Performance Bundle instead.
What warranty and returns apply?
The chiller is covered by your consumer rights: faults are repaired, replaced or refunded under the Consumer Rights Act. The suppliers don't accept change-of-mind returns, so we don't offer returns beyond your legal rights: you can cancel within 14 days of delivery under UK/EU distance-selling law, with return postage at your cost. Anything that arrives faulty or damaged is replaced or refunded.
