Cold Tubs & Cold Plunge Baths

Cold exposure is simple in theory and annoying in practice — unless you have the right setup. The Steam & Oak cold tub range is built for consistent use at home, from low-cost portable plunges to powered chillers that hold a precise temperature all year. From £395.

The range

• Portable plunges (unpowered) — the cheapest way to start: PortaPlunge CUBE (£395), SOLO (£545) and the 2-person TWIN (£595). You add cold water and ice.
• Powered chillers — set a temperature and the unit holds it: the Chill Tub Lite (£3,499), Chill Tub Original (£4,499), limited-edition Obsidian (£4,499) and the hot-and-cold Chill Tub Pro (3–40°C, £5,999).
• Hot & cold therapy — the InvigorIce Storm (£2,999) does contrast therapy in one tub.

How to choose

• Consistency beats intensity — the best plunge is the one you'll actually use weekly. A portable plunge gets you started for under £600.
• Want a set temperature on demand? Choose a powered chiller (Chill Tub / InvigorIce) — they hold the cold down to about 3°C without you hauling ice.
• Water care — filtration and sanitation on the powered tubs cut the maintenance right down.
• Space & access — measure where it will live and how it'll get there before ordering.

Cold plunge FAQs

What's the difference between a portable plunge and a powered chiller?

A portable plunge (like the PortaPlunge range) is an insulated tub you fill with cold water and ice — lowest cost, easy to store, but the temperature drifts as the ice melts. A powered chiller (Chill Tub, InvigorIce) has a refrigeration unit that holds a precise temperature — typically down to around 3°C — so every session is consistent with no ice needed.

How cold do they get?

The powered chillers hold temperatures down to about 3°C and let you set anything above that; the Chill Tub Pro also heats up to 40°C for contrast therapy. Portable plunges get as cold as the water and ice you add.

Do cold plunge tubs need plumbing?

No. They're self-contained — you fill them with a hose and empty them when you change the water. The powered chillers plug into a standard 13A socket; the portable plunges need no power at all.

How much does a cold plunge cost?

From £395 for a portable PortaPlunge up to £5,999 for the hot-and-cold Chill Tub Pro. The powered Chill Tub chillers sit between £3,499 and £4,499.

Indoor or outdoor?

Both work. Powered chillers are popular outdoors (garden, patio) and indoors (garage, utility) as long as there's a socket and drainage nearby. Portable plunges suit gardens and can be packed away.
