Cold plunge tubs · 4 min read

Which cold plunge tub should you choose?

A cold plunge tub is a tub for immersion in cold water. The key point to understand first: the tub alone does not cool the water; the chiller, offered as an option, does.

The chiller: what it changes

Without a chiller, the water in the tub is not cooled: that is the base configuration. There are two options: a chiller alone, or a chiller with heating and Wi-Fi control, which can cool or warm the water remotely.

The chiller needs a power supply and a dedicated spot. Its characteristics (output, connection) are to be confirmed with the manufacturer before the quotation.

What water temperature?

The temperature that can be reached depends on the chiller chosen, the outside temperature and the tub’s insulation; it will be confirmed with the unit’s documentation. Choosing a temperature is a matter of personal preference and physical condition.

Cold-water immersion is not suitable for everyone. If in doubt, or if you have a health condition, ask a healthcare professional before using it. SPAVOO makes no health-benefit claims.

Filtration, lighting, accessories

  • Filtration and fittings: valves and hoses, sand filter, wooden chest to house it.
  • Lighting: LED kit for the tub, additional LED.
  • Accessories: floating thermometer, headrest, stainless steel base.

Location

Plan for a flat, stable base able to carry the filled tub, a water point, a drain, truck access and, with a chiller, a power supply.

Frequently asked questions

Does the cold plunge tub cool the water on its own?

No. The base configuration does not include a chiller. To cool the water you need the chiller option.

Can a cold plunge tub be used in winter?

Usage and winterising instructions for your model will be given in the manufacturer’s documentation. A tub filled with water that freezes can be damaged.

Specifications come from the manufacturer’s catalogue; anything still to be confirmed is flagged. This site is a demonstration: no online payment.
