Optimal Tub

Full-body cold immersion. Yours alone, or paired with a chiller.

The Optimal Tub is the same insulated tub that comes with our complete Tub & Chiller systems — sold standalone for customers who want to start with ice, who already own a chiller, or who need a replacement tub.

Built for full-body immersion

- Full-body dimensions of 150×70×70cm — fits users of all sizes comfortably
- High-strength 8cm drop stitch fabric — the same material used in professional inflatable equipment
- Double-layered, fully insulated walls retain cold between sessions
- Lockable inflatable lid seals in temperature when not in use
- Drainage ports designed for direct connection to a chiller — pair with our Optimal Chiller, Chiller Pro, or any compatible third-party chiller
- Includes backpack, double-action hand pump, and repair kit — ready from day one

Who it's for

The standalone Optimal Tub suits three kinds of customers:

You want to start with ice. Fill the tub with cold water and bags of ice. Get into cold therapy without committing to a chiller setup. Upgrade to one of our chillers later when you're ready.

You already have a chiller. Connect your existing chiller to the Optimal Tub via the standard drainage ports.

You're replacing or expanding. If you already own one of our Tub & Chiller systems and need a replacement tub — or a second one for a different location — this is the same tub at standalone pricing.

How it compares to our other ice baths

- Optimal Pod ($199) — smaller (80×75cm, 350L), lighter (3.8kg), most portable. Best for one-person occasional use with bags of ice.
- Optimal Tub (this product) — bigger (150×70×70cm), full-body immersion, chiller-ready. For daily users who want a serious tub without committing to the full bundle.
- Optimal Tub & Chiller ($3,999) — the complete system. Tub plus chiller plus everything you need to set and forget temperature. Best if you want zero ice and zero hassle.

What's in the box

Optimal Tub, double-action hand pump, repair kit, backpack. (Chiller connection hoses sold separately if needed — please confirm with us before ordering if you're planning to pair with a non-Optimal chiller.)
