The overlay is the printed button-and-label sheet on the face of your topside control. This is the genuine OEM overlay for 1-pump South Seas Spas built 2021 and newer (serial number 21XXXXX and higher) running the Gecko in.k450 topside (in.ye spa pack).
Match by your existing panel, not the year alone. Count the jet-pump buttons on your current overlay and check your serial number (21XXXXX and higher = Gecko era). The Gecko topside is the same across pump counts — only the overlay differs.11-2112-11 2112-11 IN.K450
Overlay only. If your buttons no longer respond or the control is damaged, you need the complete control panel (topside + overlay) instead.
In stock and ships within our normal processing time. Easy install: with the spa powered off, peel the old overlay, clean the surface, and apply the new one with its adhesive backing.
✅ Not Sure It Fits? Verify Before Ordering
Send clear photos of your current panel (front, showing the buttons), your spa pack label, and your serial number sticker and we’ll confirm the right overlay before you order.
