Rowing Machines
Home rowing machines come in three resistance types — water, magnetic and air — and the type matters more than the brand for how a machine feels and sounds. Water gives the most realistic stroke and the quietest reputation but takes up the most floor space; magnetic folds smallest and stays quiet but feels more uniform through the pull; air scales resistance directly with effort and delivers the hardest workout, at the cost of being the loudest option by a clear margin. All three train the same full-body pulling, leg-drive and core pattern — the right choice comes down to your room and how hard you actually want to work.
The three resistance types
Every home rowing machine works one of these three ways, and the mechanism drives almost everything else about how the machine behaves.
- Water resistance
A paddle spins inside a water-filled tank, and resistance scales with how hard you pull — harder strokes churn more water and push back harder, which is the closest analogue to rowing an actual boat. Owners and reviewers consistently describe the sound as a pleasant whoosh rather than a mechanical whine, which suits flats with thin walls. The trade-off is size and weight: a water tank is bulky, most models don't fold flat, and a full one is heavy to shift or empty for storage.
- Magnetic resistance
A magnetic brake applies resistance electronically or via a manual dial, with nothing touching the flywheel. This is the quietest mechanical option and the one most likely to fold compactly, which is why most budget and space-saving home rowers use it. The stroke feel tends to be more uniform through the pull than water resistance, which some rowers prefer and others find less realistic.
- Air resistance
A fan flywheel means resistance is entirely proportional to effort — pull harder and the fan spins faster, pushing back harder, with no dial or setting to change. This makes air rowers the toughest workout in this category and a genuine favourite for interval training and CrossFit-style sessions, but the fan is also the loudest resistance type here, and the sound gets sharply louder as effort increases.
Want a named water rower specifically?
If you already know you want the realistic feel of a water tank and you're comparing specific models — WaterRower and its budget alternatives included — this page stays deliberately general. See our water rowing machines comparison for named models, UK pricing and how they stack up against each other. The rest of this page covers buying considerations that apply across all three resistance types, including water.
What to consider when buying
- Folded footprint vs assembled footprint.
Almost every rower folds or stands on end for storage, but the number that matters for a UK spare room is the assembled length while you're actually rowing — typically 2–2.2m — plus clearance behind the seat rail for your legs to fully extend. Check both figures, not just the folded one on the box.
- Monorail vs full-frame stability.
Budget rowers often use a single rail (monorail) that the seat runs along; sturdier and pricier models use a wider frame or dual rail. A monorail is fine for most bodyweights but can feel less stable side-to-side for taller or heavier rowers — worth checking the manufacturer's max user weight against your own before assuming a cheap monorail model will do.
- Seat and rail comfort over a full session.
A hard, narrow seat is the most common complaint in owner reviews across every resistance type and price point, not just budget models. A gel or contoured seat cover is a cheap retrofit if the stock seat turns out to be the problem, so it's not necessarily a reason to rule out an otherwise good machine.
- Noise — and why published figures aren't reliable.
No manufacturer in this category publishes a decibel figure you can plan around, and where owners do compare notes, real-world impressions frequently contradict what marketing copy implies. Water resistance is widely described as the quietest-sounding mechanism and air resistance as the loudest, with magnetic sitting in between, but treat that as a general pattern from owner feedback rather than a measured claim — we have not measured noise levels on this page.
- Damper or resistance range, not just the number of settings.
Magnetic rowers are often marketed by a resistance level count, similar to exercise bikes — the count isn't standardised between brands, so it tells you less than it looks like it does. What matters more is whether the lowest setting is gentle enough for a warm-up and the highest is hard enough to still challenge you months in.
What does a rowing machine cost?
Pricing varies enormously by resistance type and build quality, and we haven't independently verified a current figure for every model on the market. As a rough, unverified UK guide, expect somewhere around £150–£350 for a compact magnetic folding rower, £350–£700 for a mid-range machine with a better frame and monitor, and £500–£1,200+ for a named water rower — always check current listings, since this bracket moves and varies by retailer.
Frequently asked questions
Which type of rowing machine is quietest for a flat?
Water resistance is widely reported by owners as the quietest-sounding of the three, followed by magnetic, with air resistance the loudest by a clear margin — the fan noise scales up sharply as you row harder. No manufacturer publishes a reliable decibel figure for any resistance type, so treat this as a general pattern from owner feedback rather than a verified measurement.
Do I need a water rower specifically, or will magnetic do?
If realistic stroke feel and quiet operation matter most and you have the floor space, a water rower is the closest thing to rowing a boat. If space and folding matter more than authenticity of feel, a magnetic rower covers the same cardio and full-body training benefit in a smaller, lighter, usually cheaper package. Neither is objectively better — they suit different constraints.
Is an air rower worth the extra noise?
For interval training or CrossFit-style workouts where you want resistance that scales automatically with effort, yes — that's precisely what an air rower is built for. For steady, low-key cardio sessions in a shared building, the noise is a real downside that a magnetic or water rower avoids.
How much floor space does a rowing machine actually need?
Budget on roughly 2–2.2m in length while assembled and rowing, plus a little clearance at each end, even if the machine folds smaller for storage. Width is rarely the constraint — length is. Always check the manufacturer's assembled dimensions rather than the folded ones before assuming a machine fits your room.
What's a realistic UK price for a rowing machine?
As a rough, unverified guide, compact magnetic folding rowers commonly sit around £150–£350, mid-range machines with better build quality and monitors around £350–£700, and named water rowers typically start from roughly £500–£1,200+ depending on the model. These are broad, unverified brackets, not quoted prices — always check current listings before buying.
