Sunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower Review

The Sunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower comes with an oblique red water tank similar to the one on the SF-RW5713 Obsidian Surge water rower. But it is 60 degrees angled as the one on the Merax Rowing Machine.  

It has a strategically positioned tablet holder for entertainment purposes and a water bottle holder for staying properly hydrated during workouts.

These are important features most rowing machines lack.

The Frame and Construction 

Sunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower

The Sunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower is predominantly steel build with a small fraction that features ABS plastic material.  

Differently put, the water tank is made of polycarbonate material; the footrests, the water bottle holder, the tablet holder, and the console covers are made of ABS and nylon materials, while the frame (including the base, & the monorail) is made of gray anti-rust painted rectangular solid steel.  

As a result, it doesn’t deteriorate over time, and it supports a maximum user weight capacity of 300 lbs./136 kg.  

The overall assembled dimensions are 81.5’’ long by 21.25’’ wide by 39.5’’ high. So, you must have an area with perimeters of 6’80’’ length by 1’77’’ width for workout executions. Additionally, a clearance of 2’ all around it should be considered for a safer and better workout experience.  

Since the rowing machine is foldable, it doesn’t take up much space during storage. When folded the dimensions become 43’’ long by 21.25’’ wide by 51’’ high. Therefore, a storage area with perimeters of 3’58’’ length by 1’77’’ width will be sufficient.  

The assembled weight is 88.2 lbs./40 kg which enhances its stability.  

Speaking of, the rowing machine features front and rear steel stabilizer bars with adjustable levelers for maximum stability that doesn’t budge even when aggressively rowing.

The base is also floor-friendly because it won’t leave a scratch on any type of platform.

However, using a protective rubber mat underneath it may be a smart move that will not only prevent hole prints on a rug but also improve the overall stability.  

The rowing machine can easily be moved to and from storage area via the transport wheels at the front base.  

The Seat of the Sunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower 

The seat is large, textured, and padded with dimensions of 11.5’’ long by 14’’ wide by 2.5’’ thick. It accommodates the butt comfortably without the tendency of slipping off during workouts.  

It integrates 3 sets of sealed ball bearing rollers that are attached to the monorail. Thus, it glides steadily, smoothly, and quietly back and forth.   

The rail beam is 42’’ long and supports up to a 40’’ inseam (inner thigh to ankle length). This means users up to 6’5’’ tall can exercise with the rowing machine without a problem.

The floor to seat height is 16’’ high, fairly off the ground to enable those with joint issues or arthritis to easily get on and off the unit. 

The Handlebar 

The handlebar of the Phantom Hydro Rowing Machine is slightly curved and coated with anti-slip soft rubber foam.  

It is ergonomically designed to suit users with different shoulder-width, and it provides secure and comfortable grips.

It is attached to a 1’’ nylon strap whose other end is anchored to a recoil system. As a result, no sound is produced with each stroke you make (except the swooshing sound of the water in the tank), and no lubrication is required as opposed to a chain drive system 

The Pedals 

The pedals are adjustable in height and in width. 

They feature Velcro adjustable nylon straps and heel guards designed to secure the feet in place.

As aforementioned, the pedals are made of plastic and nylon. However, each of them sits on a 45-degree angled metallic plate that is attached to the frame. Hence, they don’t pivot but are positioned to offer good foot placement that does not stress the ankles.  

The Drive/Resistance 

This rowing machine has a belt drive system that comprises a 1” nylon belt, the recoil system, and the polycarbonate water tank.  

The water tank integrates 16 hydro blades that serve as the boat paddles for propelling or stirring the water. Each stroke you make swirls the water in the tank to produce a swooshing sound that mimics boating in a river or a lake.   

But that is not the only thing that happens when you row because resistance is generated when you pull the handlebar.

The more strokes you make create progressive resistance that ultimately challenges you. In other words, there are no predefined resistance levels or a control knob. Instead, the resistance is controlled and produced by your rowing ability.

Although, the resistance can somewhat be controlled through the level of water in the tank. The more water there is in the tank the greater the resistance and vice versa.

Therefore, you may either choose to fill the tank to the highest level with water or less depending on what you are trying to achieve.  

Again, filling the tank with water to the bream does not necessarily make you experience extreme workout challenges, you will have to pull the handlebar harder and faster to feel the burn.

This is typically good for HIIT (high-intensity interval training) that nukes fat and calories in tons within a short time of exercise.  

The noise level of the water in the tank is not high, and so, it doesn’t distract or disturb you, the family, or the neighbors. On the contrary, it is rather soothing and comforting. 

A siphon pump and a funnel are included in the package to help you remove or add water into the tank.  

The Console 

The console, tablet holder, water bottle holder, and the resistance water tank of theSunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower

The console is rectangular in shape and so is the LCD monitor it features.

The monitor has sub-windows that simultaneously track workout stats such as Time, Time/500m, SPM, Distance, Strokes, Total Strokes, Calories, Pulse, Calendar, Temperature, and Clock.  

It displays the workout metrics with good readability, and you can adjust the angle for a better view. However, the degree of its clarity might be compromised if viewed in a room with low or poor illumination because it lacks a backlight.  

The console is telemetric, but it doesn’t come with the HR wireless device. Therefore, you will have to purchase a 5.3 kHz HR chest strap separately if you wish to keep an on your heart rate report.

There are 2 different workout programs available, namely, Manual and Race programs.  

The Manual program is the normal workout mode that allows you to exercise while your workout stats such as Time, Time/500, RPM, Strokes, Total Strokes, and so on are recorded and displayed. You can also set up a goal (count-down) for Time, Distance, and Calories.  

While on the other hand, the Race program enables you to compete against the computer with virtual boats of you and the computer shown on the screen racing to reach the goal.

The race ends when either you or the computer reaches the goal.  

There is a pulse recovery function that calculates and determines the health status of your heart immediately after a workout. It usually produces a result that is between F1 (excellent) and F6 (poor).  

The monitor is powered by 2 AA batteries (included).  


The Sunny Health & Fitness SF-RW5910 Phantom Hydro Water Rower is equipped with a water bottle holder for staying hydrated, and a tablet holder for entertainment and viewing workout videos.  

These extras indeed make your workout worthwhile.

This rowing machine is foldable and portable, a recipe for easy storage.  

It doesn’t take up much space once it is folded and can easily be rolled away to any part of the room or apartment.
