Monk Cocoon Preview 2026: Everything We Know About Monk's New Ice Bath Tub

Monk has opened pre-orders for Cocoon, a new hard-shell ice bath tub that sits alongside the existing Origin and Nomad in its recovery range. It’s bigger than the Origin, built around a reclined “sculptural” interior rather than a curled-up seated position, and it’s the first Monk tub designed to work with either of the brand’s two chillers depending on budget. Deliveries for the first production batch are scheduled for August 2026, so this is a preview of a confirmed, priced product rather than a rumour.

Price and Availability

Tub only: £1,995
With Shiver chiller (cold-only, 3°C): £2,690
With Shiver Pro chiller (3-40°C, ozone filtration): £4,290

Monk is describing this as “Batch 1: last remaining units,” limited to 50 tubs in the first production run, with later orders going onto a waitlist for subsequent batches. Delivery is estimated for August 2026. UK pricing includes a two-year warranty, 60-day money-back guarantee and 0% Klarna finance over 6-36 months.

Key Specs

Size: 123.5cm (L) x 71.5cm (W) x 84.5cm (H) externally, 60.8cm internal width — 2cm wider than the Origin — and designed to fit through a standard doorway.
Fit: rated for users up to 6’9″ (203cm), with a reclined interior shape intended to allow full-body submersion without curling up, unlike Monk’s original Origin tub.
Chiller ports: three built-in ports (left, right or rear) so the chiller can be positioned to suit the room.
App control: Monk’s app handles guided plunges, breathwork sessions and audio coaching, the same software Monk uses across Origin and Nomad.
Setup: plug-and-plunge, no plumbing required, and rated for indoor or outdoor use.

Shiver vs Shiver Pro

The base Shiver chiller is cold-only, holding a steady 3°C at 0.3HP, cooling 3-4°C per hour. Shiver Pro adds heating up to 40°C at 1HP (useful for contrast therapy after a long ride or run), cools or heats 8-10°C per hour, and adds ozone plus two-stage filtration for water quality on a tub that’s likely to see near-daily use.

Available Now While You Wait

If you want cold water therapy before Cocoon ships, Monk’s existing Origin smart ice bath is available now, or the smaller Nomad for a lower-budget entry point into cold plunge recovery.
