How long does a swim spa last?

Expect roughly 15-20 years from a quality swim spa that is kept in balanced water and sheltered from constant UV exposure. Component-by-component: - **Acrylic shell:** Often 20+ years. Warranties on structure and surface are commonly 7-10 years. - **Pumps:** 5-10 years, and generally replaceable without touching the shell. - **Heater elements:** 5-10 years; shorter where water chemistry runs aggressive. - **Cover:** 3-5 years. This is the most frequently replaced item and the one that most affects running cost. - **Cabinet:** Synthetic cabinets outlast real wood, which needs sealing. The fastest way to shorten that lifespan is chronically unbalanced water. The second fastest is leaving a torn or waterlogged cover in place.
