ProRower RX-750 Water Rower | On the Water Rowing Experience

H2O Fitness says with the ProRower RX-750 Water Rower, and they’re “Bringing Commercial Grade Quality to Your Home at an Affordable Price”! The frame is exceptionally durable, so durable the manufacturer gives it a lifetime warranty. It also has a maximum user weight capacity of up to 350 pounds (159 kg).

The RX-750 uses an innovative hydro-power drive system, enabling the rower to function similarly to water resistance to someone rowing in a boat. Your rowing intensity generates the level of resistance you feel. If you take it easy and row with low energy, you get less resistance.  If you ramp up the effort and row with more intensity, you get more resistance.

The ProRower RX-750 Water Rower comes with a multi-functional performance monitor that tracks the Time, Distance, 500M Split Time, Strokes per Minute, Calories burned, and Heart Rate. Overall the ProRower RX-750 monitor is a reasonable monitor that tracks all of the necessary fitness data.

The ProRower RX-750 is sound equipment and one of the best in this price range. If you are looking for a machine that provides full-body cardio, then this one is the best. Its lifelong frame warranty itself tells its rugged build quality.

RX-750 Frame

The frame construction of this rower is quite similar to the FDF Pacific Challenge rower. It combines parts of anodized aluminum, steel, and hard plastic. It has a nice silver finish, resistant to corrosion. The frame consists of two main parts: the front part, which sustains the water tank, and the rear part, the rail with the gliding seat.

The frame rests on three bases. The front part features two bases, consisting of tubing a bit higher in diameter, finished with hard plastic caps. The front base also features transport wheels, which considerably help with the machine’s relocation and storage. The rear base is more superficial, consisting of a little square metallic tube with plastic padding on the lower part.

The frame is not foldable. However, it can be stored vertically, resting on the front base and the water tank’s metallic guard. Thus, the water doesn’t require removal from the container for the storage of the machine.

When in a vertical position, it save quite some space having a footprint of 20″L x 22″W (51 x 56 cm). On the other hand, when in a fully assembled and ready-to-use position, the machine takes quite some floor space, especially length-wise.

Its footprint is 78″L x 22″W (198 x 56 cm), therefore before choosing this machine, make sure you have the available space for it.

On the other hand, this rather long footprint is a plus, as the gliding rail is pretty long, being able to accommodate even tall users, up to 6’7″-6’8″ (200 – 203 cm), or in other words, users with an inseam up to 39″ (99 cm).

Gliding rail, seat, and footrests

This rower’s gliding rail is anodized aluminum, pretty durable, capable of withstanding a maximum user weight capacity of up to 350 lbs (159 kg). In addition, it’s completely horizontal, not slightly inclined as some other rower models, providing a correct rowing position.

The seat uses high-grade rollers, made to last for many years of use, and comes concealed to maximize safety and ensure a smooth operation.

The seat provided with the H2O ProRower RX-750 is quite full in size, with a contoured, ergonomic design meant to minimize the stress on the buttocks. If you’re wondering, the seat will give you an elevation from the floor of about 11″ (28 cm).

The footrests on this rower are not size-adjustable, but they have a pivoting design, which allows the adjustment of their angle. This is quite a great feature to have, as many rowing machines offer only fixed footrests at an angle of 45°, and not all users may be comfortable with it. In addition, the footrests feature a heel guard and adjustable straps to prevent foot slippage.

RX-750 Water tank

The water tank is pretty similar to the ones used in most other fluid rowers. It’s a polycarbonate material tank equipped with a triple-blade impeller designed to simulate the natural, water-resistance, and natural rowing feel.

The rower’s drive system involves a pulley, a belt, and a 1″ nylon bungee cord, similar to a car’s seat belt, quite durable. The bungee cord is attached to a slightly curved handle, with grips covered in rubber foam padding to prevent blistering.

The curved pulling handle helps a lot complete the stroking motion, being more comfortable pulling it closer to the chest.

The tank’s maximum capacity is 17 liters (4.5 gals), and for the proper functioning of the unit, it requires a water level between 9 – 17 liters (2.3 – 4.5 gal). The water tank does not feature any resistance adjusting dials or resistance system.

The only adjustment you can make is the water level inside the tank; the more water, the more resistance it is for the average stroke. There are markings on the side of the water tank recommending water levels for it.


On the other hand, since it’s a water-based rower, the resistance isn’t constant. Instead, it generates the amount of strength you put into each stroke; the harder you pull, the more resistance you will get.

This is pretty much the same principle as rowing an actual boat. Also, to get an idea of this rower’s overall resistance, it’s going to be pretty challenging to last for several minutes by pulling as hard as you can if you don’t have the physical shape and stamina of a professional rower.

The box includes a siphon with a flexible hose for filling/emptying the water tank. You also get chlorine pills for treating the water in the tank to prevent the formation of algae.

RX-750 Console

The performance computer supplied with the H2O RX-750 ProRower is a MyRower model. It’s a pretty basic rower fitness console but does cover all the user’s values to know during their workout.

This console displays and keeps track of time, distance, calorie/hour, heart rate, and strokes per minute (SPM). It also has a 500M function, which indicates your time for 500 meters of rowing.

The MyRower computer is relatively easy to use. It features three buttons: MODE, SET, and RESET. The MODE button is your key button for all functions. It’s for setting goals for time, distance, and heart rate.

SET is used to insert your desired value and RESET to reset the value. It also has an AutoScan mode, which will cycle through the metrics mentioned above, showing each one for 5 seconds.

This rower doesn’t integrate any sensors that can read heart rate when it comes to heart rate. However, the console is compatible with most Polar HR chest straps and will track pulse with one of those. However, an HR chest strap does not come included with the rower.

Finally, the console is battery-powered. It requires 2 x AA-type batteries. Unfortunately, the batteries do not come included with the rower either.

RX-750 Assembly and Maintenance

The assembly of the ProRower RX-750 is far from being confusing. It shouldn’t take more than 30 minutes. There are eight steps to assemble this unit, and the whole assembly requires you to connect the rail to the central part of the frame, add the seat, the rear base, and attach the console.

And, of course, fill up the tank by using the siphon and funnel provided. The owner’s manual comes with the rower and several tools necessary for the assembly.

The machine isn’t wholly maintenance-free. It requires changing and treating water in the tank from time to time with the supplied chlorine pills. As a general idea, if you run out of chlorine pills, just about any 1″ chlorine pill for pool use should do. They can’t possibly generate any damage to the tank.

Other than water replacement and treatment, the rollers may require greasing from time to time. The gliding rail must also be kept free from any debris to avoid any damage to the rollers.

ProRower H2O RX-750 Water Rower Summary

The H2O Fitness ProRower RX-750 Water Rower is one of the best and most affordable fluid rowers that you can find at the moment.

Although it doesn’t offer the full range of “belts and whistles” a commercial-grade rower typically provides, it still is a machine pretty close to the quality of those used in most gyms. So think of it as a gym-grade rower, tweaked for home use.

Moreover, it’s an excellent machine for a low-impact full-body workout for users of all levels; it supplies a natural rowing feel and has a relaxing effect. And lastly, it’s an excellent price/quality ratio that won’t break the bank.

  1. Thank you so much for your review of ProRower H20 RX 750. During this quarantine time, I have to start exercising from home. I don’t want to be a host for this coronavirus and make somebody sick.

    I have never tried a rower with a water tank before, but I like the water resistance method. It can be convenient for me to move it around as well; all I have to do is just to empty the water chamber. I have to say it is affordable! Let me talk to my husband; I am sure we will get it.  

    • Thanks for your interest in the ProRower RX-750 Rower from H2O Fitness. This RX-750 is easily relocated due to the front base having two transport wheels. It’s not necessary to drain the water tank before moving or storing it vertically. The water won’t leak from the tank.

      Stay safe, and be well!

  2. The ProRower H2O RX-750 Rower with Hydro-Power Drive System is a very creative and innovative exercising machine. I imagine the water tank gives a real semblance of rowing on the water. For sure, the user will experience a realistic semblance of the environment.

    What is the price of this equipment? Is it hard to set-up? What about maintenance? 

    If the price is affordable along with the excellent warranty and after-sales service, this machine is ideal for virtual training.

    • The RX-750 is an extremely affordable quality rower. The MSRP is $999.00. However, when in stock you’ll find the RX-750 between $699 and $799.

      The whole assembly requires you to connect the rail to the central part of the frame, add the seat, the rear base, and connect the console. It shouldn’t take more than 30 minutes to complete.

      For maintenance, you’ll need to periodically (every 6 months) add a chlorine tablet to prevent algae growth in the water tank. I would drain the water from the tank once a year and refill with fresh water. However, it’s my preference and you are not required to do so. I also suggest using distilled water in the water tank but again it is my preference and it’s not required.

      Lastly, you’ll need to keep the gliding rail free of debris to prevent damaging the rollers on the seat.

      Thanks for your interest in the ProRower RX-750 Rower from H2O Fitness.

      Stay safe, and be well!

  3. If I am wanting to leave my rower where it would freeze, can I just put antifreeze in the tank? I will come back to our cabin several times over the winter and would want to use it

    • Hi Teresa,

      My advice would be to drain the water tank and refill it when you wish to use the rowing machine. I believe putting anti-freeze into the tank would void the warranty.

      Kind regards, Robert
