✅ 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 spa pack / control system label
- Your existing WiFi module and its sticker, if replacing one
- Your spa serial number sticker
EZ Hot Tub Parts can help confirm fitment before you order and help reduce costly returns.
59303 is Balboa’s factory number for the ControlMySpa Ultra Gateway kit (US/Canada), printed on the module sticker and box.
Yes. Those are the retired bwa long-range (59-138-2010) and short-range (Artesian 33-1315-08) modules. Balboa retired the bwa app platform, and this ControlMySpa kit is the factory-current replacement on the same BP-series systems.
Check the label on your spa pack in the equipment bay. BP-series labels read BP or MBP (for example MBP501UX). VS, MVS or EL on the label means this kit does not fit.
