✅ 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.
Read the label on your existing spa pack or board and match it — not the model year. Photograph the label and send it through the form on this page and we will confirm the match before you order.
Both are possible. Island Spas moved from Balboa to Gecko with the 2025 update, but prior-generation “Classic” spas continued to sell through 2025 and into 2026. The model year does not settle it. The label on the pack does.
