✅ Not Sure It Fits? Verify Before Ordering

Island Spas parts vary by model, model year, trim and generation. Spas built during the 2025/2026 changeover may be current-generation or “Classic” carryover, so the model year alone does not settle it — match your spa pack label.

To help us identify the correct replacement, please send clear photos of:

  • Your existing part, including any label
  • Your spa serial number sticker
  • Your spa pack / control system label

EZ Hot Tub Parts can help confirm fitment before you order and help reduce costly returns.


Match the amperage and voltage on your existing motor label first — those are what keep the pump inside your spa pack’s breaker and relay rating. Then confirm speeds, frame size and intake/discharge plumbing size. Horsepower and BHP figures are marketing numbers with no consistent convention and should not be used to match a pump.

Island Spas changed shells, filters and electronics for the 2025 model update, and prior-generation spas continued to sell alongside them as “Classic” models. There was no January 1 cutoff, so the model year on its own does not identify the generation — read the label on your spa pack, or send us a photo of it and we will identify it for you.
