A modernized electronics package reduces fluctuations in jet power, while the streamlined design minimizes vibrations and noise. The result is a calmer, more consistent soak that you can count on for daily spa-like relaxation.

Key features that elevate your hydrotherapy

Installation and compatibility at a glance

The K-73524 kit is designed for straightforward retrofit within most standard Kohler whirlpool configurations. Key considerations include:

• Most installations require no plumbing modifications, and the compact base helps keep the setup quiet and stable.
• If upgrading from an older model, replacing the pump base helps prevent vibrations and ensures quiet operation.
• Electric compatibility: this replacement operates at 120V. If your current setup runs on 240V, you’ll need electrical voltage conversion.
• Safety first: plan for a dedicated GFCI-protected circuit to ensure safety and peak performance.
• Positioning: place the control box under the tub for easy access while maintaining a tidy installation.

Who this is for

Ideal for homeowners with aging Kohler whirlpool baths seeking reliable, customizable hydrotherapy without the hassle of frequent maintenance. It’s a smart retrofit for those who want to restore consistent jet action, reduce noise, and enjoy spa-like patterns with Wave and Pulse modes—all in a compact, easy-to-install package.

Practical tips for best results

• Before installation, verify 120V wiring and ensure a dedicated GFCI-protected circuit is in place.
• Replace the pump base if you’re moving up from an older unit to minimize vibrations and maximize quiet operation.
• Position the CG AIR SYSTEMS Control Box where it’s accessible but out of the way to keep the tub area clean.
• Use the Wave and Pulse modes to experiment with different hydrotherapy patterns—start with Pulse for a gentler start, then switch to Wave for broader coverage.

With the K-73524 Kohler Whirlpool Bath Pump Replacement, you’re not just swapping a component—you’re reimagining your soak. Expect reliable performance, intuitive control, and customizable hydrotherapy that fits seamlessly into your daily routine.
