Entry tubs can cost hundreds, insulated rigid tubs around the low thousands, modular chiller systems several thousand, and premium integrated systems well above that. Real ownership cost includes ice or electricity, filters and sanitizer, water, covers, plumbing, drainage, service, and possible structural work.
Quick comparison
| Tier | System | Main hidden cost |
|---|---|---|
| Entry | Portable tub + ice | Recurring ice and water changes |
| Vessel | Insulated tub | Chiller still separate |
| Modular | Tub + external chiller | Pump, hoses, filtration, service |
| Integrated | All-in-one | Delivery, weight, proprietary repair |
How to estimate a year
Record sessions per week, ice per session, local rates, filter schedule, sanitizer, drain volume, and expected service. Use a range rather than a single perfect number, because climate and hygiene habits dominate operating cost.
