Endless Pools vs Hydropool swim spas

Endless Pools uses a propeller in 4 models (E-Series) and jets in 5 (R-Series and X-Series). Hydropool uses jets in 9 models (Aquatic Collection, Executive Collection and Play Collection).

A propeller turns behind a grate and pushes one wide column of water. Jets fire water through a few nozzles, often with air mixed in, so the current is narrower and more broken up. What you feel is the width and steadiness of the water, not the horsepower on the spec sheet. The guide to swim spa jets vs propeller explains the trade-offs.

Endless Pools publishes the open swim area for 6 of its 9 models; the longest is 137.5 by 81 in, on the E550. Hydropool publishes the open swim area for all 9 models; the longest is 153 in, on the AquaTrainer 17AX.

Outside lengths run 12 ft to 20 ft for Endless Pools and 12 ft 6 in to 18 ft 10 in for Hydropool. By length class, Endless Pools has 2 in the 12-foot class, 4 in the 14-foot class and 3 in the 16-foot class; Hydropool has 1 in the 12-foot class, 3 in the 14-foot class and 5 in the 16-foot class. At the dealer, lie out in an empty display of the model you would buy, arms overhead: your feet shouldn't reach the seats. See swim spa sizes, 12-foot swim spas, 14-foot swim spas and 16-foot swim spas, and best swim spas for lap swimming.

Water held runs 1,080 to 2,395 gallons for Endless Pools and 1,345 to 2,409 for Hydropool. More water means more to heat, treat and carry: have a builder or engineer check the pad or deck for the filled weight.

Endless Pools' models call for 30 to 60 A in total on 1 circuit; Hydropool's call for 50 to 100 A on 1 to 2 circuits. The top of each range is the X2000 and the AquaTrainer 19DTAX. A licensed electrician sizes the circuits for the model you buy. See swim spa electrical requirements.

Only Endless Pools has filings we could match: its 7 filed models draw a median 462 W, about 337 kWh a month holding temperature. None of Hydropool's 9 models matched a California filing, so ask the dealer for the model's listing before you compare. The swim spa running cost guide explains the test.

Endless Pools' structure warranty runs 10 years, equipment 3 to 5 years; coverage does not transfer. Hydropool's structure warranty runs 10 years, equipment 3 years; coverage does not transfer. Read the warranty card for labor and the swim system itself, which some makers cover for less time than the shell.

Endless Pools posts list prices from $26,499 to $74,999 (checked Oct 2026). Hydropool doesn't post prices, so a dealer's quote is the only figure. Swim spa cost covers delivery, the pad and the electrician.
