Island Spas Topside Control & Overlay (2013–2018) – OEM Replacement (OP11-1105-11)

The original Island Spas topside control used on 2013–2018 Island Spas models has been discontinued by the manufacturer. The factory now supplies an updated OEM assembly — OP11-1105-11 — that includes both the topside control and the matching overlay, and it is the direct replacement for the discontinued OP11-1303-08, OP11-1304-08, and OP11-1312-08.

If your original topside matches the discontinued photo above, this is the correct current replacement.

Frequently Asked Questions

Yes. The original Island Spas topside controls used on 2013–2018 models (part numbers OP11-1303-08, OP11-1304-08, and OP11-1312-08) are discontinued and no longer manufactured.

Yes. This listing supplies the current-production OEM topside control and overlay, part number OP11-1105-11, which supersedes all three discontinued part numbers. You are ordering the current replacement on this page — no separate listing is needed.

No. Island Spas Elite models used a different topside control (OP33-1319-08) and the two are not interchangeable. If your spa is an Elite model, see the Island Spa Elite Topside Control (2013–2018) instead.

This OEM replacement fits standard (non-Elite) Island Spas models built from 2013 through 2018 that originally shipped with one of the following discontinued controls:

  • OP11-1303-08
  • OP11-1304-08
  • OP11-1312-08

The original part number is printed on a label on the back of your existing topside control. If it matches any of the numbers above — or if your control matches the discontinued OEM photo shown on this page — this is the correct direct replacement.

No. OP11-1105-11 is the factory-designated replacement and uses the same connection as the original. Unplug the discontinued control, install the new one, apply the overlay. No wiring modifications and no programming changes are required.

This topside control is designed to work with the compatible
