  • Unparalleled instruction opportunities
  • Variable-speed hydraulic underwater treadmill(s)
  • Custom sizing with our modular construction
  • Expert installation from our nationwide network of Factory-Trained Installers

Why are Endless Pools so Competitively Priced?

  1. We make and sell in greater volume. As the leader in counter-current pools, we manufacture more than 1,500 units a year, more than any other company.

  3. We design for ease of installation. Our 200+ Factory-Trained Installers are fast and experienced, so they can quote you a reasonable price.

With space on either side, staff can be comfortably in the pool with the student/patient. This affords unparalleled rehab and instruction opportunities while making it easy for the user to step out of the current.

HydroWorx pools feature resistance jets only. They deliver a shallow, narrow, turbulent current.


Fully modular with steel-panel construction. All pieces fit through doorways and down stairs. Installation is possible virtually anywhere.
