You’ve decided a rowing machine belongs in your home gym. Smart move. But now you’re staring at two completely different beasts: the smooth, living-room-friendly WaterRower with its mesmerizing water tank, and the no-nonsense Concept2 RowErg that every CrossFit box and Olympic training center trusts. Both are excellent. Both will humble you in under five minutes. But they feel, sound, and perform differently enough that picking the wrong one means buyer’s remorse — and a very expensive coat rack. If you’re stuck in the water rower vs Concept 2 debate, this comparison breaks it all down so you can stop overthinking and start rowing.
Quick Answer
If you want the bottom line on the water rower vs Concept 2 showdown: the WaterRower Natural wins for home gym owners who want a quiet, beautiful machine that blends into their living space and delivers a smooth, realistic rowing feel. The Concept2 RowErg wins for athletes and serious fitness enthusiasts who prioritize performance tracking, competitive benchmarking, and proven durability above all else. Neither is a bad choice — it depends on whether you train for aesthetics and feel or for data and performance.
TL;DR
The WaterRower Natural offers gorgeous design and whisper-smooth water resistance that feels like rowing on an actual lake. The Concept2 RowErg is the gold standard for performance metrics, durability, and competitive rowing. Pick the WaterRower for your living room; pick the Concept2 for your garage gym.
Key Takeaways
- Water resistance (WaterRower) feels natural and self-regulating — the harder you pull, the more resistance you get, with no settings to adjust.
- Air resistance (Concept2) is the industry standard for performance tracking, with the PM5 monitor used in every rowing competition worldwide.
- Noise levels differ significantly — the WaterRower’s gentle swoosh is living-room friendly, while the Concept2’s fan whir is better suited for a dedicated gym space.
- The Concept2 stores upright in about 2 feet of floor space; the WaterRower stores vertically against a wall.
- Long-term durability favors the Concept2, which has machines still running strong after 20+ years in commercial settings.

Overview: What Is a Rowing Machine?
A rowing machine simulates the motion of rowing a boat on water. You sit on a sliding seat, push off with your legs, and pull a handle toward your chest. It’s one of the few pieces of gym equipment that works roughly 86% of your muscles in a single stroke, according to the American Council on Exercise. That makes it one of the most efficient full-body cardio tools you can own.
The two main resistance types in this comparison are water and air. Water rowers use a paddle inside a sealed water tank — you literally hear and feel the water with every stroke. Air rowers use a flywheel and fan to generate resistance. Both are “dynamic” resistance, meaning the harder you pull, the more resistance you encounter. There’s no dial to set a specific resistance level the way you would on a magnetic rower.
The real differences come down to feel, sound, aesthetics, data tracking, and long-term reliability. Let’s break each one down.

WaterRower Natural — Full Breakdown
WaterRower Natural is the machine you buy when your rowing machine lives in a shared space. Handcrafted from solid ash wood with a honey oak finish, it looks more like a piece of Scandinavian furniture than gym equipment. The water tank creates a self-regulating resistance that genuinely mimics the catch and pull of rowing on open water. It’s quiet enough to use during nap time or while your partner watches TV in the next room.
The S4 monitor covers the basics — distance, speed, stroke rate, calories, and heart rate (with a chest strap). It’s functional but won’t compete with the Concept2’s data ecosystem. The 700-pound weight capacity is impressive, and the dual-rail system feels stable for larger users.
The honest limitation? The S4 monitor feels dated, app connectivity is bare-bones compared to the Concept2, and the water tank requires occasional purification tablets to stay clean.

Concept2 RowErg — Full Breakdown
Concept2 RowErg is the machine that needs no introduction in the fitness world. It’s the same rower used in every Olympic training center, CrossFit gym, and rowing club worldwide. The PM5 monitor is the gold standard — it tracks every metric you could want, syncs with the free ErgData app, connects to Strava, and lets you race other rowers online through the Concept2 logbook.
Build quality is industrial. The aluminum monorail and steel frame are built to survive decades of daily abuse in commercial settings, let alone your garage. The damper setting (1–10) lets you adjust airflow to change the feel of each stroke — though it doesn’t change actual resistance, which is still effort-based.
The trade-offs? It’s louder than the WaterRower. The fan generates a noticeable whir that fills a room. And aesthetically, it screams “gym equipment,” so it won’t win any interior design awards sitting in your living room.

Category-by-Category Verdict
Feel and Rowing Experience
The WaterRower wins here for most casual rowers. The water resistance provides a smoother, more organic stroke that closely mimics on-water rowing. There’s a satisfying “catch” at the beginning of each pull that air rowers can’t quite replicate. The Concept2 feels slightly more responsive and aggressive, which competitive rowers prefer but beginners sometimes find jarring.
Winner: WaterRower Natural
Performance Tracking and Data
This isn’t close. The Concept2’s PM5 monitor is the universal language of rowing. Every benchmark, every competition, and every training program references Concept2 metrics. The ErgData app, online logbook, and third-party integrations (Strava, Apple Health) make it the clear winner for anyone who trains by numbers.
Winner: Concept2 RowErg
Noise Level
The WaterRower produces a gentle swooshing sound — think small fountain or fish tank. Most people find it relaxing. The Concept2 generates a fan-driven hum that gets louder the harder you row. It’s not obnoxious, but it’s noticeable. If your rower lives near bedrooms or shared living spaces, the WaterRower wins easily.
Winner: WaterRower Natural
Durability and Longevity
Concept2 has machines in commercial gyms that have logged millions of meters over 15 to 20 years. Replacement parts are cheap and widely available. The WaterRower is well-built too, but the wood frame requires more careful treatment — keep it away from direct sunlight and humidity extremes. The water tank seal can occasionally need attention.
Winner: Concept2 RowErg
Aesthetics and Home Friendliness
The WaterRower Natural is genuinely beautiful. It looks like furniture. It stores vertically against a wall and takes up minimal visual space. The Concept2 looks like what it is — commercial gym equipment. If your rowing machine sits in a living room, den, or bedroom, the WaterRower is the obvious choice.
Winner: WaterRower Natural
Value for Money
Both machines sit in the premium price range, but the Concept2 edges ahead on pure value. Its PM5 monitor alone justifies the price for serious users, replacement parts cost a fraction of the competition, and resale value stays remarkably high. The WaterRower holds value well too, but replacement components can be pricier.
Winner: Concept2 RowErg

FAQs
Is a water rower better than an air rower?
Neither is objectively better. Water rowers offer a quieter, more natural rowing feel suited for home environments. Air rowers like the Concept2 provide superior data tracking and durability. Your choice depends on priorities — ambiance or analytics.
How loud is the Concept2 compared to a WaterRower?
The Concept2 produces a moderate fan whir around 60–70 dB at full effort. The WaterRower stays closer to 40–50 dB with a soothing water swoosh. The difference is significant in shared living spaces.
Does the WaterRower need a lot of maintenance?
Minimal. Add a chlorine purification tablet every few months to keep the tank water clean, and wipe down the rails after each session. The wood frame benefits from occasional treatment with Danish oil to maintain its finish.
Can you really compare WaterRower and Concept2 metrics?
Not directly. The WaterRower’s S4 monitor and the Concept2’s PM5 use different algorithms. A 2:00/500m split on one machine doesn’t equal the same effort on the other. If comparing times matters to you, the Concept2 is the standard everyone uses.
Which rower is better for weight loss?
Both burn roughly the same calories for the same effort level. According to the National Strength and Conditioning Association, rowing can burn 400–800 calories per hour depending on intensity. The machine matters less than consistency and effort.
How much space do I need for a rowing machine?
Plan for about 9 feet long by 4 feet wide of clear floor space during use. Both the WaterRower and Concept2 store upright when not in use, freeing up most of that footprint. Ceiling height isn’t a concern since you stay seated.
Do water rowers lose resistance over time?
No. Water resistance is generated by the paddle moving through water — it doesn’t degrade. You can adjust resistance slightly by adding or removing water from the tank. The mechanical resistance stays consistent for the life of the machine.
Final Verdict
The water rower vs Concept 2 decision comes down to one question: where does this machine live, and what do you want from it?
If you’re building a home gym in a shared space and want something quiet, beautiful, and smooth to row on, the WaterRower Natural is the clear pick. It delivers a rowing experience that’s genuinely enjoyable, and you won’t feel the need to hide it when company comes over.
If you’re a data-driven athlete, a CrossFitter, or someone who wants the most proven and durable rowing machine on the planet, the Concept2 RowErg is the answer. There’s a reason it’s been the standard for decades — nothing else matches its performance tracking, community, and bulletproof reliability.
Either way, you’re getting one of the best full-body cardio machines money can buy. Pick the one that matches your space and your goals, and start logging meters.
