Product Overview

WaterRower "Oak S4"

The Natural Oak meets the high standard of quality that you can expect from any WaterRower model. Each of our rowing machines has been hand finished with three coats of Danish Oil giving a deep lustre and warmth to the wood.

The WaterRower Oak is handcrafted in solid ash wood and comes with a honey oak stain. It features a double rail, an elevated seat and the S4 Performance Monitor, so as to offer you an incomparable full-body workout.

The original

The WaterRower was invented by John Duke in 1988. The American rower developed the rowing machine’s easy function and timeless design from the basic idea, that dry land training should simulate the given conditions on water as closely as possible.

Timeless design

Timeless appeal and prestige: the WaterRower rowing machine received the PlusX Award for its unique design and was also the only piece of sports equipment on display at the Design Museum of London.

A way of life

The WaterRower blends the tranquility of moving water, the warmth of wood, and the rhythm of motion. These qualities combine to provide a naturally pleasurable activity. Invigorating the body while relaxing the mind and involving little to no impact on the joints. Composed to capture the aesthetics of rowing, the WaterRower is enjoyable to use. The calming tones and smooth action encourages the user from stroke to stroke. The symphony of these elements engage the user with a satisfaction which should be experienced!

The perfect exercise

WaterRower Benefits

The rowing stroke uses 84% of the Muscle Mass and is able to burn over 1000 calories per hour. From the tips of the fingers holding the handle/oars, to the balls of the feet connected to the footboard/boat, all the muscles between these two points contribute to the rowing stroke.

There is no jerkiness or jarring which is often associated with conventional mechanical rowing machines making the exercise unpleasant; only smooth even load, kind to the body, and relaxing to the mind.


How it works

The WaterRower’s unique WaterFlywheel has been designed to reproduce the precise physical dynamics of a moving boat; the surest way to replicate the physiological benefits and aesthetic pleasure of rowing.

Like rowing, the WaterFlywheel does not apply resistance to you, you apply work to it; you are the engine! By the “rule of cubes”, the amount of work you apply dictates the speed at which you row. Because water is 800 times more dense than the air, the more work you do, the more resistance/drag you can overcome and the faster you move.


The extremely durable, rubber feet provide protection and skid resistance for all types of flooring. The frame is made of solid wood, capable of withstanding the toughest of workouts.


During your workout the seat glides silently on the rails, according to your rowing stroke. Eight ball bearing mounted rolls made of anti-abrasion polyurethane ensure perfect rolling on the rails. The seat is ergonomically cushioned, further providing comfort during use.


The foot board offers the highest level of flexibility when in an optimal rowing position. The ergonomic foot pads and straps are both individually adjustable, guaranteeing maximum comfort.

The S4 Monitor

High performance

The sleek S4 Monitor displays important workout data at all times, such as speed, time, calories burned, strokes per minute or distance. 

Your performance monitor can also be connected with the free rowing software "We-Row", to help you compete online against other WaterRower owners around the globe.


Rowing software

Connect, free of charge, with We-Row and race against other WaterRower owners. Or, if you prefer, set up your own private training session. You will have the option to store your data and access at any time, which will allow you to chart your progress and also share with other users.

The software is available freely for Mac OS, Windows and Linux. Its only system requirements are an active internet connection and a WaterRower with an S4 Monitor, which comes with a USB port (2.10 firmware).

Water tank

The WaterRower’s resistance is generated in its unique water tank element. No manual adjustment is necessary to increase/decrease resistance, it precisely adjusts to the user’s movement and strength input.

Save space

In an upright position, the WaterRower occupies no more space than a chair. Its center of gravity lies at the water tank which enables you to lift it effortlessly at the rail-end. In any position, the water remains safely in the tank.

More than just a rower

Renowned design

Our Rowing Machines are functional fitness furniture, designed not to be hidden away like other unsightly gym equipment, but to look at home in your living room. 

Storing in an upright position no wider than a dining room chair, our rowing machines can be easily laid out for a quick indoor rowing exercise session.

Commitment to the environment

Environmental ethos

For 30 years our wooden machines have been handcrafted in the United States, using only verified sustainable hardwoods from the Appalachian region. Our goal is making rowing machines of superb quality and beautiful design, while keeping our commitment to protect the environment.
