Is the Smart Chiller right for you?

Unlike the Pro, Horizontal, and Vertical, this isn't a tub — it's the chiller unit alone, designed to turn a tub you already have into a full temperature-controlled recovery system. Pick this one if you don't want to buy an entirely new tub, or you already have a suitable container and just need the cooling, heating, and filtration hardware.

It's also the only model in the lineup that heats as well as cools, so it's the pick if you want contrast therapy (alternating hot and cold) rather than cold-only.

Who it's for: people who already own a tub or vessel, or who want both hot and cold rather than committing to one temperature.
What we like: works with your existing tub, adds heating on top of cooling, LED touchscreen for control without needing your phone.
What to know before buying: no tub is included — confirm your tub's size and material are compatible with the chiller before ordering, per Sun Home's spec sheet.
