About this topside/keypad

This MAS425/460 4-button spa overlay is a genuine OEM replacement part designed for Master Spa control systems. The long-format overlay features four clearly labeled control buttons that restore full functionality to your spa's topside control panel. Built to Master Spa's exact specifications, this overlay ensures reliable operation of your spa's essential functions.

At Bubbles Supply, we guarantee this overlay will fit your Master Spa system perfectly with our exact fit guarantee. Every overlay ships the same day you order and comes backed by our comprehensive 1-year warranty for complete peace of mind. Installation is straightforward – simply remove the old overlay and apply the new one to your existing control panel, ensuring all button alignments match your system's configuration before final positioning.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Buttons no longer responsive or hard to press
  • Button labels faded or worn off
  • Overlay cracked, peeling, or physically damaged
  • Water infiltration under the overlay causing button failure
  • Panel displays incorrect function due to misaligned or degraded overlay

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your topside control unit is the MAS425 or MAS460 model — check the label on the underside of the topside panel or in your spa's documentation
  • Verify your existing overlay has exactly 4 buttons — this overlay will not fit 2-button or 6-button variants
  • Count and compare button layout and spacing on your existing overlay before ordering
  • Inspect the topside housing for cracks or damage — if the housing is broken, a new overlay alone will not restore functionality
  • Check whether the underlying membrane/switch pad is also damaged — if so, the overlay replacement alone may not fix unresponsive buttons

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
