What Horsepower Is the Hydro Pump on Each Ella Walk-In Tub Model?

Ella does not publish a horsepower figure for the hydro pump on each walk-in tub model. The current spec sheets rate the pumps in amps and watts instead, so the Standard's hydro pump is listed at 8.1 amps and 900 watts, the Elite's hydro pump at 5 to 7 amps, and the Tub4Two's seat pump at 9 amps and 1250 watts. The only pumps given a horsepower rating are the 1 HP microbubble pump and a legacy hydro massage pump part. What size pump does the Ella Elite use with each therapy package? breaks down one model in detail; this page collects every published hydro pump rating across the line and explains why horsepower is not the figure to shop by.

Why the Sheets List Amps and Watts Instead of Horsepower

The number your electrician needs is the current draw, because that is what sizes the dedicated line and the GFCI protection. Every jetting configuration has its own electrical requirements, so Ella publishes an electrical diagram for each therapy package rather than for the model name alone, and the pump, heater and control draws on that diagram are in amps. Horsepower appears only where a specific pump is sold or labeled that way, such as the optional MicroBubble Therapy pump.

There is a second reason the model name cannot give you a pump rating. Ella has changed hydro pumps several times over the years, so two tubs with the same model name from different years can have different pumps under the seat. The figures printed on the current spec sheet for your model, and on the label of the pump itself, are the ones to rely on. If you are planning wiring for a new order, use the current sheet. If you are checking an installed tub, read the pump label behind the access panel.

Published Hydro Pump Ratings by Model and Family

The table pulls together every hydro pump figure that appears in the current published sources. Where a figure is not published the cell says not listed. Jet counts belong to the therapy package, not the model name, so the jets column names the package the figure comes from.

What the differences mean: the published pump tiers run from the standard hydro pump on single-seat tubs, through the medium pump on the two-seat tubs, to the Hercules on the Big4Two. Within those tiers the amp figures vary by model, so a Standard at 8.1 amps and an Elite at 5 to 7 amps are both standard-tier single-seat pumps with different ratings on their sheets. Packages that pair hydro with a second hydro pump or with the microbubble pump are the ones listed with two dedicated lines, which is the practical consequence for your electrician. A legacy hydro massage pump part is listed at 1 HP and 900 watts, which is the one place a horsepower figure attaches to a hydro pump, and it describes an older part rather than a current model.

Where Horsepower Does Appear

Two figures in the published sources carry a horsepower rating. The optional MicroBubble Therapy pump is listed at 1 horsepower and 7.3 amps, and a legacy hydro massage pump part is listed at 1 horsepower and 900 watts. Neither figure should be read across to the hydro pump on another model. If a listing or a competitor's comparison asks you for the horsepower of an Ella hydro pump, the honest answer is the amp and watt rating on the current spec sheet, and the team can read that figure to you for the exact model.

Two Pumps for Independent Foot Massage

The video on this page shows why some Ella hydro packages carry two hydro pumps. With independent foot massage and full body hydro massage, one pump runs the seat jets and a second pump runs the foot jets, each with its own intensity control dial. Competitors typically use one pump and a diverter valve that takes power from one side to send it to the other, which produces a weaker, inconsistent flow. On an Ella tub you can run full power to just your feet or to your entire body. On the Elite this shows up on the sheet as two hydro pumps rated 5 to 7 amps each, and on the Tub4Two as a 9 amp seat pump and a 7 amp foot and calf pump.

Replacing a Hydro Pump

If you are asking about horsepower because a pump has failed, the model name will not identify the replacement on its own, since the pumps have changed over the years. Open a ticket at ellasbubbles.com/support with your model, serial number and therapy package, a description of the problem, and photos of the pump and its label. The team identifies the correct replacement from those photos and ships it under the parts warranty after verification. Ella does not send technicians, so a local licensed electrician or plumber does the labor. Ask the team to confirm exactly what is included with the replacement pump for your serial rather than assuming, and request the electrical diagram for your package so the installer knows which line each pump, heater and control plugs into. Can I Get an Electrical Diagram or Parts List for My Tub? covers how to download the diagram from the Therapy Options tab on your model's page.

Before the new pump runs, fill the tub 1 to 2 inches above the highest hydro jet. Running a pump dry causes permanent damage that is not covered by the warranty. Unlike a hot tub pump, the hydro pump runs only while you are in the bath, as How Does a Walk-In Tub Compare to a Hot Tub? explains, so a monthly vinegar flush and a clean inlet cover are the only routine care it needs.
