Individual Reviews
Apartment Setup — Inflatable + Portable Chiller
Inflatable tubs fold flat when not in use. Put down a large catch-tray before first use, not after the first flood.
Garage / Basement Setup — Dedicated Circuit
Chiller units draw enough continuous power that shared circuits can trip breakers. A licensed electrician check before install is cheap insurance.
Backyard / Patio Setup — Permitting and Drainage
Larger stainless tubs are effectively semi-permanent installations. Some municipalities treat them like hot tubs for permitting — worth a quick call to local building code office.
Which One Should You Choose?
- Renting or limited space: inflatable, indoors, with a floor tray.
- Garage with power access: dedicated circuit, any chiller model.
- Backyard, permanent setup: check permitting first.
