Revitalize your Whirlpool Bath with the Aqua Glass R100VS4C Variable Speed Pump System—a purpose-built retrofit kit designed to restore power, control, and serenity to aging tubs. If your old control box or pump has failed or become obsolete, this Gemini Plus Pump Retrofit Kit delivers a seamless path back to the spa-like experience you expect, without the disruption of replacing the entire tub.

Why this retrofit matters

Old Aqua Glass control systems and pumps age, and parts become unavailable. The R100VS4C retrofit kit not only restores performance but modernizes your tub’s control experience with a responsive remote, clear speed options, and quieter, steadier operation. You’ll enjoy more dependable performance, improved hydrotherapy, and a noticeably premium feel during every soak.
