General Specifications
About the Product
The WaterRower A1 Home Rowing Machine is a water resistance rowing machine that uses paddles suspended in a tank of water to create resistance. The “variability” of resistance on the A1 Home Rowing Machine functions very similarly to how resistance on an air resistance rower operates.
The WaterRower Natural rowing machine is handcrafted in solid ash wood, stained Honey Oak, and finished with Danish oil. Wood is an excellent material for this application due to its ability to absorb sound and vibration enhancing the WaterRower's smooth, quiet operation. The Natural, as with all WaterRowers, features patented WaterFlywheel technology, unrivaled in its replication of the resistance felt in on the water rowing.

What customers say about "Key Specs"
WaterRower A1 Home Rowing Machine
  • The small footprint of this rower was one of the main reasons I bought it.
  • The action is very smooth and comfortable and you can adjust the resistance by adding more or less water to the drum between the clearing defined limits.
  • The main things I like about this rowing machine are the fact it uses water so you get a natural resistance when rowing.
  • I recommend this to just about anyone, as you create the resistance, so you only get out of it what you put in.
  • The only other issue is that you can not adjust the level of resistance without adjusting the volume water in the tank.
WaterRower Ash S4 Natural Rowing Machine
  • Variable resistance adjustment determined by rowing intensity.
  • Unique Water Flywheel mechanism that allows for a more realistic rowing experience.
  • Quiet and very smooth operation, but with the added benefit of a realistic wave-like rowing feel.
  • The WaterRower Natural Rowing Machine is not an ideal machine for households with limited space.
  • It is noisy and has a huge footprint and makes whatever room it's in into the "gym room".

What customers say about "Design"
WaterRower A1 Home Rowing Machine
  • It is easy to store and looks more like a piece of furniture when not in use.
  • Most models made in wood and would fit in quite unobtrusively in your living room.
  • Filling/draining the water is slow having to use the supplied pump. At the full water level it's tricky to move the unit w/o spilling water.
  • To store it upright you need to drain it. These a problem to me as it take a lot of time.
  • Foot straps are of a moulded plastic that catch when trying to get your shoe in or out and the sharp edges make it impossible to row bare foot.
WaterRower Ash S4 Natural Rowing Machine
  • Very comfortable seat - probably the best we've tried so far.
  • Can be easily stored by positioning the machine vertically and keep it in a convenient space.
  • Sturdy and durable construction made of premium quality hardwood and finished with top-of-the-line materials.
  • The seat and cords work smooth, no need of grease or other lubricants. So no risk of getting dirty.
  • The foot straps are crap! Within the first 1000m of moderate rowing they loosen to the point of being able to pull foot out on recovery of stroke.
  • It squeeks: the machine makes a lot more noise than I expected, not because of the water moving, but because of the wheels on the seat.

What customers say about "Features"
WaterRower A1 Home Rowing Machine
  • The built in computer is easy to use and gives me all the information I require.
  • Very quiet. Pretty much the only noise is the sloshing of the water in the tank.
  • Monitor can be programmed for different measurements and countdowns. It's simplifies workout.
  • It's quiet enough to row and watch TV with, I have found it mentally refreshing to just focus on the rowing without background noise.
  • The monitor has display which is hard to see in bright sunlight and impossible to see in dim lighting.
WaterRower Ash S4 Natural Rowing Machine
  • Console can be plugged into your PC for additional features.
  • Allows for racing against AI, against personal best, and against other online fitness buffs.
  • The easy to read display keeps track of progress and at the same time motivates to increase progress.
  • I was very upset that computer, does not track calories.
  • The computer is a bit poor. The power button is so soft it frequently gets stuck down so if I want to pause it by pushing it, it gets stuck and resets!
