SEE REPLACEMENT PART: OBSOLETE

When a topside panel starts to look worn, faded, or hard to read, the spa can feel older and less intuitive even if the electronics underneath are still working well. This 12-button ML900 topside panel overlay is designed to refresh the visible control surface on compatible Balboa ML900 systems, restoring button labeling clarity and improving the overall presentation of the spa interface.

Overlays matter because they are the part customers interact with directly. If labels are peeling, bubbling, or faded, it becomes harder to use the spa with confidence. A fresh overlay can improve usability immediately while also giving the spa a more maintained, higher-value appearance. In sales and service environments, that kind of visual improvement can have an outsized effect.

Because this overlay is made for the ML900 format, it helps preserve original button layout and intended visual design. That is a major advantage over trying to improvise with non-matching graphics or generic overlays that do not line up properly.
