WaterRower Natural Rowing Machine | Smooth, Natural, and Quiet

The WaterRower Natural Rowing Machine with S4 Monitor is one of the most aesthetically pleasing rowers on the market. It is also one of the best-performing ones! It is part of the “Natural” series of WaterRowers, due to its solid Ash Wood and stained Honey Oak construction material.

It uses a “water flywheel” or paddles suspended in a water tank to provide the rower’s resistance. Therefore, this is called ‘variable’ resistance because there are no “adjustments” to feel more resistance, row faster, and feel less resistance, row slower.

In addition to determining resistance based on your rowing intensity, you can further adjust the rowing experience by adding or subtracting water from the water tank. The more water you add, the “heavier” the rowing will feel (like rowing a boat with passengers). The less water you have, the “lighter” the rowing will feel (like rowing by yourself).

The WaterRower Natural Rowing Machine provides one of the best resistance any water rowing machine offers. Therefore, it is difficult to find any complaints about WaterRower resistance. It is smooth, durable, and relatively quiet. Plus, it closely mimics the resistance felt while rowing on the water!

Natural Frame

First, this rower’s frame is ashwood-made, with a sleek and “warm” finish, reminding me of an actual boat. Second, the frame comes coated with Danish oil, which results in a smooth finish without being glossy or slippery, considerably increasing its liquid resistance.

Since it’s a wood frame, it absorbs shock and vibration much better than a metallic frame, also being lighter.

The WaterRower Natural takes quite a bit of space length-wise, 82.25 (209 cm long) regarding its footprint. It also requires at least 20″ (51 cm) clearance at the back, and about 12″ (30.5 cm) on each side, to ensure safe training.

Therefore, make sure you have the required available space for it before purchasing. On the other hand, the machine can store vertically when not in use, occupying 20 x 22.25 x 82.25 inches (51 x 57 x 209 cm) (L x W x H).

The frame features rubber feet to ensure maximum stability and prevent damage to the flooring if the machine is placed directly on the floor. Also, the front end features transport wheels to facilitate the relocation and storage of the rower.

Being a more extended machine, this water rower can accommodate tall users, with an inseam of 37″ (94 cm). In general, users up to 6’6″-6’7 ″ (198 – 201 cm) tall should not have any difficulties training on this machine. As for the supported user weight, you shouldn’t worry about it. This rower is rated to support users up to 700 lbs (317 kg).

Seat and Handle

The seat of this WaterRower comes without cushioning. However, it has a contoured design to adapt better to the user, eliminate the numbness effect, and facilitate the rowing motion. In addition, it supplies a horizontal glide, simulating a natural rowing stroke.

The footrests are oversized, accommodating feet of any size. They’re also equipped with straps to prevent slippage of feet and help them achieve a correct rowing motion.

The rower’s handle is simple, with rubber foam grips to absorb sweat, ensure a good grip, and prevent palm sores or blisters. The handle comes attached to a durable nylon strap, a material similar to the one used in automobile seatbelts.

Natural Water tank

Like any water rowing machine, this model includes a water tank with quite a sizeable WaterFlywheel, consisting of two paddles enclosed in a container. This water flywheel emulates the dynamics of a boat moving through water. Therefore, this machine renders a very natural rowing feel with every stroke. The resistance adjusts naturally, just like rowing a real boat: the harder you pull, the more resistance.

The water tank has a volume higher than 19 liters. However, 19 liters is the maximum water quantity. Adding more water into the tank can lead to the voiding of the warranty. WaterRower recommends that the basin shouldn’t contain more than 17 liters of water. The tank has pretty clear level markings on it. Also, the water can remain in the container when the rower stores it vertically.

The tank is made of polycarbonate material and is gray-colored. The subtle blue color depicted in some of the photos is water dye. Unfortunately, the water dye isn’t (supplied) with the rower. However, the box does include chlorine pills to be added to the water to prevent algae or mold formation.

S4 Console

The WaterRower Natural rowing machine comes with an S4 performance tracking monitor. It has a user-friendly interface, even though it’s a pretty advanced unit. It can display all the values a professional rower wants to know during training.

In other words, this unit will indicate intensity (or speed), watts, KCalories per hour, stroke rate, heart rate, distance covered, and time spent on a training session.

The unit has interval workout settings for length and intensity and 9 Advanced Workout Programs. The S4 monitor is telemetric. However, it requires a heart rate chest strap, which does not come with the rower.

Also, the S4 performance monitor is a PC interface capable of via a monitor cable. We-Row, WebRacing, and WaterCoach Fit are several commercially available software apps. They allow you to join online rowing communities, compete with others, or customize your workout.

The S4 performance monitor is battery-operated and requires 4 AA-type batteries.

Natural Assembly and Maintenance

The WaterRower Natural ships in two boxes, one for the rails (6 x 6 x 30 inches), one for the water tank and console, and the other (24 x 24 x 24 inches). The assembly part is relatively easy, requiring ten main steps, which should take no more than 30 minutes of your time.

It requires you to combine the two main rails, add the seat, water tank, footboard, and transport wheels, and connect the bungee cord to the recoil belt and the console. The manual and the necessary tools come with the machine.

If you may be wondering, all frame pieces already have holes drilled into them, so you must put the nuts in and screw them in place.

Maintenance also doesn’t require much. All you need to do is change the water in the tank every six months and add a new chlorine pill. Since the wooden parts of the frame have Danish oil, other than occasional dusting, the wood requires no maintenance.

Also, ensure you keep the rails clean of any dirt or particles that might be nick. Also, keep the console from moisture or wipe any water or sweat droplets that might fall on it during a workout.

Note: This WaterRower rowing machine has a base warranty of one year. However, if you register the product on the WaterRower official website, the warranty automatically extends to five years for the frame and three years for the parts.

  1. Fantastic , thank for this review.

    This looks beautiful and would ideally suit the home gym I’m refitting at the moment.

    I’ve been trying to get away from bulky robot looking machines that are not aesthetically pleasing because I want a calm environment to do gentle exercising rather than the muscle man body building look. This certainly fits the bill. Thank you.

    Do you have any other recommendations that will compliment this water rower?

    • Thanks for your interest in the WaterRower Natural Rowing Machine. For recommendations, it depends on what type of equipment you want. NordicTrack makes appealing stuff such as the S22i studio cycle, or the Endurance E5000 Elliptical from Body-Solid is another.

      All the best!

  2. It is a piece of beautiful workout equipment. I like it because its design gives me a warm feeling, the whole structure is easy to store and free guarantee.  

    Usually, workout equipment is steel.  This wooden made machine gives me no clumsy feeling and impresses me very much.  People who like doing exercises will love it.  In this regard, I will recommend to my friends if they are going to plan a home gym.

    Your article is beneficial and very informative. Thank you for sharing.


  3. This device looks excellent for anybody who wants to advance in the rowing world. In addition, water resistance makes sense when preparing for a general rowing or aerobic training competition.  

    It does take up a significant amount of space; this is something that people will have to consider before buying. However, if rowing is the person’s passion, this tool would be the way to go. It’s still cheaper than going to a gym because once you own it, you own it without a subscription. Some assembly is required, and it does come in 2 boxes. However, with an estimated 30 minutes to assemble, it’s not bad. 

    • Hi Nel, thanks for stopping by and sharing your thoughts with us. Would you please let me know if I may further assist you with exercise equipment? I’m always happy to help.

      Kind regards, Robert

  4. I have to be honest about this product; I don’t like it. It’s great to be innovative, but the product has to back it up. The water resistance is excellent, and I am sure this rowing machine will do the job. However, with the wood frame and cheap seat, this would be uncomfortable while working out. This product looks like someone built gym equipment in the garage.

    • Hi Chuck, thanks for stopping by and sharing your thoughts. WaterRower is a highly-rated rowing machine manufacturer, and their equipment is well-made. Case in point, this machine has a 700-pound user weight limit.

      Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert
