Wood Type and Display Specs
display type
You get a slight edge with the WaterRower Walnut S4 Handcrafted Rower because it includes the S4 BLE Monitor. This model supports Bluetooth Low Energy connectivity, allowing you to pair the machine with external devices for data tracking. The WaterRower Ash Rowing Machine uses the standard S4 Monitor, which does not list Bluetooth capabilities in its specifications. If you want to sync your rowing metrics to a phone or tablet, the Walnut version is the better choice. Otherwise, both displays show the same core rowing data.
build material
The primary difference between these two machines is the wood used in their construction. The WaterRower Walnut S4 Handcrafted Rower is crafted from walnut wood, which features a signature chocolate-brown coloration with hints of gray, red, and purple tones. Each piece has unique variations. The WaterRower Ash Rowing Machine is made from ash wood with a natural color finish. Both are hand-built in the USA using sustainably sourced hardwoods. Your choice depends on whether you prefer the rich tones of walnut or the lighter, natural look of ash.
resistance type
Both rowing machines use identical water resistance technology. They feature the WaterFlywheel, where paddle-like blades move through water to create smooth, natural resistance. The harder you pull, the more resistance you generate. This mechanism mimics the feeling of rowing on actual water. Neither machine lists adjustable resistance levels or magnetic systems. You get the same full-body workout experience with both the Walnut and Ash models, targeting eighty-four percent of total muscle mass through this consistent water-based resistance system.
weight capacity
The weight capacity specification is identical for both models. Both the WaterRower Walnut S4 Handcrafted Rower and the WaterRower Ash Rowing Machine list a weight capacity of 103.5 lbs when filled with water. This figure represents the total weight of the machine itself, not the maximum user weight. The data does not specify a separate maximum user weight limit for either model. You can assume the structural integrity is similar, as both are handcrafted in Rhode Island using the same core design principles.
form factor
Both machines share the same footprint and storage design. The WaterRower Walnut S4 Handcrafted Rower and the WaterRower Ash Rowing Machine both measure 82 inches in length, 20 inches in height, and 22 inches in width. They are designed to stand vertically on end for easy storage. The base unit weight differs slightly, with the Walnut model weighing 61.7 pounds and the Ash model weighing 63.9 pounds. This minor difference does not impact the space requirements or the ease of moving the machines around your home.
Which rower matches your needs
Users wanting app connectivity and data tracking
Choose the WaterRower Walnut S4 Handcrafted Rower if you need Bluetooth Low Energy support. The S4 BLE Monitor lets you pair the machine with external devices to track your workout data. This connectivity feature is not available on the Ash model, making it the better choice for tech-focused training.
Buyers preferring natural wood aesthetics and finish
Select the WaterRower Ash Rowing Machine for its natural color finish. This model is crafted from Ash wood, offering a distinct look compared to the Walnut variant. If you prefer the lighter, natural tone of Ash over the chocolate-brown Walnut, this machine delivers the same handcrafted quality with a different visual style.
Shoppers seeking the lightest machine for storage
Opt for the WaterRower Ash Rowing Machine if you prioritize a lighter frame. This model weighs 63.9 pounds, which is slightly lighter than the Walnut version at 61.7 pounds dry weight. The difference is minimal, but the Ash model offers a marginally lower weight for easier handling and storage.
