Buy the WaterRower A1 if the WaterRower name, the wood frame, and the upright storage matter and the monorail and basic monitor are acceptable. Buy the Sunny SF-RW5910 if you want a larger tank, a steel frame that needs no wood care, and Sunny parts support at a mid price.
Wood against steel
The A1 is solid ash on a monorail: real WaterRower wood at the line's lowest price, with the upright storage the brand is known for. The Sunny is a steel frame with a large tank and no wood to care for, which suits garages and utilitarian rooms. Wood can be oiled and refinished over years; steel asks nothing of you. The material choice is also a room choice: the A1 belongs in a living room, the Sunny in a training space.
Rails and ride
Both machines ride a single rail, so neither offers the dual-rail glide of the premium WaterRowers. The A1's monorail can feel like it rocks slightly at the catch, owners report, while the Sunny's single beam rail is a plain steel glide. At steady paces both are quiet and smooth; at sprint rates both show why dual rails cost more. The ride difference between them is smaller than the material difference.
Monitors and support
The A1 carries a quick-start monitor that is simpler than the S4, reporting the basics without the S4's feature depth. The Sunny carries a basic digital LCD with rowing metrics. Support is where the brands diverge in character: Sunny's parts and support are easier to reach than no-name budget brands, while WaterRower's parts and accessory ecosystem is the deepest in the category, shared across the whole line. Buyers planning decade ownership should weigh the ecosystem, not just the monitor.

FAQ
Water Rowers questions, answered straight
Which rows better at sprint rates?
Neither is a dual-rail machine, so both are steady-pace rowers first. The A1's monorail can rock slightly at the catch under hard efforts; the Sunny's single rail is plainer but no better at sprint rates. For interval training, the dual-rail models in this guide are the honest upgrade.
Do both store upright?
Yes. The A1 stores upright like every WaterRower, in about a two-foot square of floor. The Sunny also stores upright to save floor, per its listing. Neither needs draining for upright storage between sessions.
