I have taught well over a thousand people to row on indoor machines, at a CrossFit box and then at a dedicated rowing studio, and the question I get more than any other is some version of this one: of all the best home rowing machines, which one should I actually put in my living room? The honest answer is that the machine is maybe 20 percent of the workout and your technique is the rest, but that 20 percent still matters, because a machine that fights you is a machine you stop using by February. I have rowed everything from a $300 magnetic wobble-fest to a Concept2 that has outlived three owners, and I can tell you exactly where the money goes and where it doesn't.
The short answer: the Concept2 RowErg is the only rowing machine I recommend without caveats, the WaterRower Club is the one I would keep in my own living room for the feel, and the Sunny Health and Fitness Premium Water Rower is the value pick for a household that wants water resistance on a smaller budget. The fourth item in this comparison is not a machine at all, and that is on purpose. It is the chain oil that keeps a chain-driven erg from turning into a squeaking clothes rack.
Concept2 RowErg Indoor Rowing Machine
The PM5 monitor shows split and drag factor, air resistance feels honest through the whole stroke, and it splits in two for storage
No screen, no classes, no subscription ecosystem, and the fan is loud by design
WaterRower Club Rowing Machine with S4 BLE Monitor
The closest feel to real water, handcrafted USA-made frame, and it stands upright against a wall like furniture
The tank is a maintenance project, and the S4 monitor is basic compared with the PM5
Sunny Health and Fitness Premium Water Rower
300 lb capacity, dynamic real-time resistance, flips up for storage, and an optional free app connection
Build and rail feel are a step down from the two above, and the app is a bonus rather than a coaching system
UniSport Concept 2 Rowing Machine Chain Oil (8 oz)
Made in the USA, 8 ounces lasts years, and it is compatible with the Model D and other major chain-driven brands
It does nothing for a water rower, and it will not fix a chain that is already rusted

How I judge a rowing machine
I do not start with the frame or the price tag or how it looks in a product photo. I start with four questions, and they have never led me wrong.
Does the resistance feel consistent from the catch to the finish? Does the monitor show split, meaning time per 500 meters, rather than leaning on a calorie number the machine is guessing at? Does the seat roll smooth and stay quiet on the rail? And would I put a beginner on it for their first twenty-minute steady-state session without apologizing for the machine?
That last one is the real test. A rowing machine is not furniture and it is not a gadget. It is a tool for a repetitive motion you will repeat thousands of times per session. If the tool makes that motion feel vague or sticky, your form falls apart, and bad form on an erg is how people end up with a sore lower back and a machine they resent.
So this comparison is not about which machine has the longest feature list. It is about which one gives you a drag you can trust, a monitor you can believe, and a seat that does not click on every drive.
Concept2 RowErg: the standard, and it earns it
If you have ever rowed in a gym, a boathouse, or a CrossFit box, you have rowed on this machine. The Concept2 RowErg with the PM5 monitor is the reference point for a reason, and it is the machine I recommend when someone wants one answer and no follow-up questions.
The resistance is air, driven by a fan, and you control the feel with the damper and read the actual resistance with drag factor on the PM5. That distinction matters more than almost anything else in this article. The damper is just a lever, and most people crank it to 10 because it feels harder, which is not the same as better. Drag factor is the number that actually tells you what the flywheel is doing, and it changes with air density, so a machine in a cold garage reads differently than one in a warm studio. The PM5 gives you that number, along with split, stroke rate, and interval programming you can set without a phone.
It also gives you the least glamorous and most useful feature in home fitness: a device holder and a monitor that never asks you to subscribe to anything. The RowErg splits into two pieces and stands up, so it stores in a corner or a closet. The frame is famously durable, which is why used ones hold value in a way that no budget rower does.
What it gives up is atmosphere. There is no touchscreen, no instructor talking you through a workout, and no class library. The fan is loud because moving that much air is loud. If you want a machine that entertains you, this is not it. If you want a machine that tells you the truth about your pace every single stroke, this is the one, and a decade of gym abuse has not changed that.
WaterRower Club: the one I keep at home
Here is my confession: I recommend the Concept2 to almost everyone, and the machine in my living room is a water rower. The WaterRower Club with the S4 BLE monitor is handcrafted in the USA, and the flywheel is a tank of water with paddles in it. That sounds like a gimmick until you pull on it. Water resistance builds through the drive the way a boat does, and the sound is a soft rush rather than a fan roar. For me it is the closest thing to real rowing that fits in a house.
The Club frame is solid wood, and it looks like a piece of furniture rather than a piece of gym equipment. It stands upright for storage, which is how it survives in a one-bedroom apartment. The S4 BLE monitor is Bluetooth-capable, so you can push your numbers to apps and log sessions, and it covers the basics you need: time, distance, and pace.
Where it loses is in the two places that matter to the person paying the bill. First, the tank is a maintenance project. You treat the water, you watch the fill level, you keep it out of direct sun, and you pay attention to the seals and the tank over the years. Second, the S4 is a basic monitor next to the PM5. It gives you your session data, but it does not have the interval programming depth or the drag factor readout that a Concept2 owner takes for granted.
That is the trade. You are buying feel and looks, and you are accepting a maintenance relationship in return. If you will actually do that maintenance, it is a wonderful machine. If you will not, the tank will tell on you.
Sunny Health and Fitness Premium Water Rower: the value pick
The Sunny Health and Fitness Premium Water Rower is the third machine here, and it is the one I would point a friend toward if they wanted water resistance without the top-tier outlay. It carries a 300 lb capacity, it uses dynamic real-time resistance, and the frame flips up for storage. There is an optional SunnyFit app connection, and the app itself is free rather than a subscription gate.
For a household with two or three people of different sizes, that capacity matters. It is also the machine that stores smallest in this group, which makes it a legitimate option for a small apartment or a shared room where the rower has to disappear when it is not in use.
What you give up is refinement. The rail and seat feel is a step down from the Concept2 and the WaterRower Club, and refinement is exactly what you notice at minute eighteen of a steady-state session, not in the first thirty seconds. The app is a nice bonus, but it is a phone-based tracker rather than a coaching system, so do not buy this machine expecting the app to make you a rower.
If your budget points here, buy it with clear eyes and use it. A used machine you actually row on beats a perfect machine you admire from the couch.
The chain oil, and why it is in this comparison
The UniSport Concept 2 Rowing Machine Chain Oil is the cheapest item here and the one that most people ignore until something starts squeaking. It comes in an 8 oz bottle, it is made in the USA, and it is formulated for exercise rower chains, compatible with the Model D and other major chain-driven brands.
Why does it belong in an article about machines? Because on a chain-driven erg, the chain is the drivetrain. It carries every watt you produce from the handle to the flywheel. A dry chain runs rough, wears faster, and adds a rasping noise that makes the whole machine feel cheap. A lightly oiled chain runs quiet and smooth, and suddenly the erg feels like the machine you paid for.
The honest boundaries of this recommendation matter. This oil is for chain machines, so if you own the WaterRower Club or the Sunny water rower, skip it, because your drivetrain is a tank of water and the maintenance you owe it is water treatment, not lubricant. And oil is prevention, not repair. If a chain is already rusted and stiff, lubricant will slow the decline but not undo it.
One bottle of this size will last most home owners years, and it is the single lowest-effort thing you can do to keep a chain-driven machine feeling new.
What the monitors actually tell you
If you take one thing from this comparison, take this: the monitor matters more than the frame.
The PM5 on the Concept2 shows split and drag factor, which means it can answer the only question that matters mid-session, which is whether this pace is sustainable and whether your resistance setting is where you think it is. It also handles interval programming directly, so a 6 x 500 meter session does not require you to watch a clock.
The S4 BLE on the WaterRower Club gives you the session basics and Bluetooth, which is enough for steady-state work and app logging, but it is not a performance tool in the same way. The SunnyFit connection on the Sunny rower is the lightest of the three, a phone-based companion that adds convenience rather than precision.
And a note on calories, which I will say once and then get off my soapbox: the calorie number on any rowing machine is an estimate built on assumptions about your body that the machine cannot verify. Split does not care about your assumptions. Split is the honest number. Learn to read it and you will improve faster than any calorie counter will ever show you.
What each machine asks of you in maintenance
An air rower asks you to keep dust out of the flywheel housing, check the chain for dryness and oil it, and pay attention to the bungee cord that retracts the handle. That is roughly a ten-minute job a few times a year.
A water rower asks you to manage the water. That means treatment to keep it clear, checking the fill level, watching for weeping around the tank seals, and keeping the frame out of direct sunlight so the wood does not dry and shift.
Any rower asks you to clean the rail and the seat rollers. If the seat clicks or catches, that is the machine telling you something, usually grit on the rail or a roller that needs attention. Listen to it early, because a seat that skips mid-drive ruins your rhythm and your rhythm is the whole workout.
The technique note that no purchase fixes
Whatever you buy, the machine will only ever be 20 percent of the result. The other 80 percent is what you do at the catch and the finish.
Slow the stroke down. Drive with the legs, finish with the body and arms, then reverse the order on the recovery: arms, body, legs. Keep the damper around a 3 to 5 or set drag factor deliberately rather than cranking the lever to 10 and calling it intensity. For steady state, sit around 20 to 24 strokes per minute and hold a split you can repeat for twenty minutes without your form breaking down. For intervals, go shorter and harder than feels comfortable and let the monitor hold you accountable.
A Concept2 owner with sloppy form will get beaten by a Sunny owner with good form every single time. Buy the machine you will maintain and use, then go learn the stroke.
Which one should you buy
Buy the Concept2 RowErg if you want the industry standard, the most honest monitor, and zero subscription. It is the machine I recommend without caveats, and it holds value if you ever sell it.
Buy the WaterRower Club if you want the closest thing to the feel of water, you care how the machine looks in your home, and you will genuinely do the tank maintenance. I keep one for exactly those reasons.
Buy the Sunny Health and Fitness Premium Water Rower if you want water resistance and easy storage at the value end of the range, your household has a range of body sizes, and you accept that the rail and seat will not feel like the two machines above it.
And whatever chain-driven machine you end up with, keep the UniSport chain oil on the shelf. It costs almost nothing, it takes a minute, and it is the difference between an erg that feels like a tool and one that sounds like a complaint.
