Why this Sunny SF-RW5910 rowing machine earns its spot
The only folding water rower Sunny sells in our catalog
Sunny's Premium Water Rower delivers the same water-resistance feel but stores upright only. This AquaStrive model folds flat on its transport wheels, which is the deciding factor if you need the floor back between sessions.
A review sample we could verify in full
Every one of the 10 review excerpts collected for this listing checked out against this exact model's own specs, with several owners naming the SF-RW5910 or Phantom Hydro by name. That's a rare clean result in a category where Sunny's pooled review pages are the most common contamination risk we track.
What owners keep saying
This review draws on all 10 owner reports collected for this listing. Every excerpt checked out against this exact model's own specs, with no capacity, model-number, or feature contradictions found, so the sentiment below reflects the full sample rather than a filtered subset. Amazon's own aggregate for this listing sits at 4.4 out of 5 across 671 ratings.
The honest cons
- Foot straps are the one recurring durability complaint. Two separate owners reported theirs failing right around the 6-month parts warranty boundary, and one had to order a full replacement pedal-and-strap set
- The meter has no backlight, which multiple owners found hard to read in dim rooms
- One owner needed help from Sunny's customer service for a loose meter screw; response was prompt in that case, but response times vary across the brand based on other reports in our broader Sunny research
- Resistance is set only by the amount of water in the tank, so mid-workout adjustments mean stopping to add or drain water rather than turning a dial
Sunny AquaStrive vs Sunny Premium Water Rower vs JOROTO Water Rower vs WaterRower Ash

FAQ
How is this Sunny SF-RW5910 rowing machine different from Sunny's other water rower?
This AquaStrive model folds flat and rolls away on transport wheels, while Sunny's Premium Water Rower (model SF-RW5713) in our catalog stores upright against a wall only. Both use 16 hydro blades and a 300 lb capacity, so storage is the main deciding factor between them.
Is this Sunny water rower quiet enough for an apartment?
Yes, one owner measured the sound with a decibel meter from 3 feet away and never recorded above 65 db, roughly the volume of a nearby conversation. Multiple owners describe being able to watch videos or hold a conversation while rowing.
How long does the foot strap last on this Sunny rowing machine?
This is the one real durability concern in our verified sample. Two separate owners reported their straps failing right around the 6-month parts warranty boundary, and one had to order a full replacement pedal-and-strap set. Check yours periodically for fraying.
Is this Sunny rowing machine good for tall riders?
Yes, based on real owner reports. One owner at 6 feet 3 inches, 240 lb, with a 34-inch inseam described the machine as supporting his weight with a rigid, commercial-quality feel, and another over 6 feet 4 inches reported enough rail travel to fully extend.
How long does assembly take on this Sunny water rower?
Owners in our verified sample most commonly report 30 to 40 minutes working solo, mainly because the water tank and frame come mostly pre-assembled from the factory.
Can I adjust the resistance mid-workout on this Sunny rowing machine?
Not on the fly. Resistance depends on how much water sits in the tank, so changing it means stopping to add or drain water rather than turning a dial like you would on a magnetic rower. Most owners fill to a level they like once and then vary effort by rowing harder or softer, since water resistance already scales with stroke speed.
Does the monitor on this Sunny water rower have a backlight?
No, and that's a real complaint in the owner reports we verified. Multiple owners found the display hard to read in a dim room and worked around it with a small clip-on light or by rowing near a window.
The verdict
The short version: this Sunny SF-RW5910 rowing machine has the cleanest review record of any Sunny rower in our catalog. Every one of the 10 review excerpts we collected checked out against this exact model, several of them naming the SF-RW5910 or Phantom Hydro directly, so the sentiment below reflects the full sample rather than a filtered subset. Owners consistently describe a quiet, smooth water-rowing feel with room for tall riders, and the one real recurring weak point is the foot strap, which two separate owners reported failing right around the 6-month parts warranty boundary.
Buy it if you want a genuine water-rowing feel that folds away when you're done. Skip it if a fixed foot rest matters more to you than swivel comfort, since the straps are the one documented durability concern here.
