WaterRower Walnut with S4 BLE Monitor
The WaterRower Walnut rowing machine is the darkest, richest wood option in WaterRower's handcrafted lineup, built from solid walnut rather than a walnut-look finish over a cheaper wood. It runs the same WaterFlywheel water resistance and S4 BLE monitor as the rest of the WaterRower trio, and at 163 Amazon reviews averaging 4.6 out of 5, it holds the highest rating of the three premium wood listings in our catalog, at the highest price of the three as well.





- Solid walnut construction, independently confirmed by the spec sheet, the manufacturer's own bullets, and multiple owners who checked
- Highest average rating of the three WaterRower listings we carry, 4.6 out of 5
- Owners report the machine holding up well 5 years into daily use with no reported issues
- Handcrafted in Rhode Island from sustainably sourced hardwood, genuinely USA made
- Same WaterFlywheel resistance and S4 BLE monitor as the Oak and Club siblings, so the workout feel does not change even though the wood does
Where the WaterRower Walnut lands against the other rowing machines in our catalog: Beats the Oak and Club siblings on average rating and wood quality, loses to both on price, Beats the JOROTO on craftsmanship and finish, loses to it on price and folding storage, Loses to the Concept2 RowErg trio on weight capacity, wins on noise for shared-wall apartments.

Why the Walnut earns its spot in this class

Solid walnut, confirmed three separate ways
The spec sheet, the manufacturer's own bullets, and multiple independent owners all agree this is solid walnut wood, not a stain or veneer over a cheaper species. That kind of independent agreement across sources is rare, and it is why this listing earns the highest confidence rating of the three WaterRower pages we carry.
The highest owner satisfaction of the WaterRower trio
At 4.6 out of 5 across 163 reviews, this listing beats both the Oak (4.5) and Club (4.4) siblings on average rating, and multiple owners report years of daily use with no reported problems.
What owners keep saying
This waterrower walnut rowing machine review draws on the pattern across all 9 available Amazon review excerpts out of 163 total for this exact ASIN, all of which checked out clean against this machine's confirmed solid-walnut, 300 lb, S4 BLE specs.
The honest cons
- Highest price of the three WaterRower listings in our catalog
- The title's 'Best Warranty' claim is not backed by a stated duration anywhere in this listing's own data, so we cannot confirm it
- 300 lb weight capacity, the same ceiling as the rest of the WaterRower trio
- Stores upright rather than folding flat, which needs ceiling clearance a folding budget rower does not
WaterRower Walnut vs Oak vs Club vs JOROTO Foldable Water Rower
All three WaterRower listings in our catalog share the same WaterFlywheel resistance, S4 BLE monitor, and 300 lb capacity. Wood species, rating, and price are what actually separate them.

FAQ
Is the Walnut really solid wood, or just a finish?
Yes, solid wood: this exact listing's spec sheet, the manufacturer's own bullets, and at least one owner who specifically checked all confirm it as genuine solid walnut, not a walnut-look stain applied over a cheaper wood.
Does this WaterRower have the best warranty in the lineup?
The listing title claims 'Best Warranty,' but no specific duration or terms appear anywhere in this ASIN's own product data. We are not going to repeat a marketing claim as fact when we cannot trace a number behind it. If warranty length is a deciding factor, confirm the specific terms directly with WaterRower or the seller before ordering.
What is the waterrower walnut rowing machine weight capacity?
300 lb, the same figure across all three WaterRower listings in our catalog.
How does this compare to the Oak and Club on price?
It is the most expensive of the three WaterRower listings we carry. The tradeoff is wood: this is the only one of the three built from solid walnut rather than natural oak or stained ash, and it also holds the highest average owner rating of the three.
How long do these machines last?
We do not have a manufacturer-stated lifespan, but one review on this exact ASIN, dated roughly 5 years after the original purchase, still rates it 5 stars with no reported problems. That is a single owner's experience rather than a guarantee, though it is a genuine long-term data point, more useful than a fresh-out-of-the-box review.
Does this rower need an app to work?
No, the S4 BLE monitor tracks time, distance, and stroke data standalone. Bluetooth connectivity lets it pair with apps if you want extra tracking, but nothing about the base machine requires an account or subscription.
Is water resistance quiet enough for an apartment?
Quieter than an air rower, though not silent. Water resistance makes a rushing, splashing sound as the paddles turn, distinct from a magnetic rower's near-silent operation and an air rower's fan whir. Most owners describe it as pleasant rather than disruptive, but it is worth knowing the sound exists before you set this up against a shared wall.
How is this powered, given the different spec listing than the Oak and Club?
This exact ASIN's spec sheet lists the S4 monitor as adaptor-powered rather than battery-powered, which differs from the Oak and Club listings in our catalog, both of which state 4 AA batteries. We report this as sourced rather than assuming it is a typo, since we have no basis to override this listing's own stated spec.
The verdict
The short version: this is the premium pick of WaterRower's wood lineup. Solid walnut, not a stain or veneer, confirmed independently by the spec sheet, the manufacturer's bullets, and multiple owners who specifically checked. It carries the highest average rating of the three WaterRower listings we carry, 4.6 against 4.5 and 4.4, and owners consistently describe it as elegant, quiet, and holding up well over years of daily use.
Buy this one if the dark walnut finish matters to you and you are willing to pay the premium for solid hardwood over a stained or lighter alternative. Choose the Oak or Club siblings instead if wood species is not a priority and you would rather save money, since mechanically all three are the identical machine.
