KingSmith WM10 Hydromagnetic Rowing Machine
A rubber-wood rowing machine combining water and magnetic resistance, so the load can be set precisely rather than only by stroke rate. Folds in three.
Why you'll love it
- The feel of water, the control of magnets. Water gives the smooth, natural catch; 32 magnetic levels let you dial in the exact load on top of it. Pure water rowers can't do that.
- Looks like furniture. A solid rubber-wood frame that you won't want to hide in the garage.
- Folds in three. From 81.5 in long to 31 in stored. One person can fold it and tuck it against a wall.
- Fits almost anyone. 331 lb capacity, users up to 7 ft 4 in, adjustable footrests, phone holder on the console.
- Ships from a US warehouse, no assembly. Dispatched within 48 hours, delivered in 2–6 business days, free. Unfold, add water, row.

Frequently asked questions
Tap a question to open the answer.
▸ WM10 or WR20 — what's the difference?
The WM10 adds 32 magnetic levels on top of the water, so you can set a precise, repeatable load; peak resistance is 110 lb. The WR20 is water only, with a higher 176 lb peak for hard pulls. Structured training and controllable intensity: WM10. Maximum raw load and the purest water feel: WR20.
▸ Do I have to fill it with water? Does it leak?
Yes, you fill the tank once with tap water using the included pump (2.9–4.0 gal depending on the level you want). The tank is sealed; add a water-treatment tablet every few months to keep it clear. No draining needed between sessions.
▸ How loud is it?
The water makes a soft rushing sound with each stroke; there's no fan noise like an air rower. Fine for an apartment.
▸ How much space does it need?
81.5 × 18.9 in in use. Folded in three it's 31 in long and stands against a wall.
▸ Does it track my workouts?
Yes. The console shows time, distance, strokes and 500 m pace, and the KS Fit app syncs sessions to your phone, Apple Health and Apple Watch.
▸ Is assembly required?
No. Unfold it, fill the tank and row.
▸ Is the extended protection plan a monthly subscription?
No. It is a single one-time payment made at checkout. There is no monthly charge, no renewal and nothing to cancel later.

Warranty and returns
Every WM10 comes with a 12-month limited warranty covering the frame, tank, resistance mechanism and console. The full terms are in our warranty policy.
Returns are accepted within 30 days of delivery in original packaging. Items delivered between 1 November and 31 December may be returned within 45 days. See our refund policy for the full terms.
Optional extended protection
You can add an extended protection plan from Consumer Priority Service (CPS), our warranty partner, when you order. It begins where the 12-month manufacturer warranty ends and can take total coverage up to six years.
- One single payment — never a monthly rate. You pay once at checkout. There is no subscription, no recurring charge and nothing to cancel later.
- 100% of parts and labor for mechanical and electrical failure, including manufacturing defects and hardware failure.
- Home and commercial use are both covered — the plan is valid whether the rowing machine sits in your bedroom or in an office.
- If it cannot be repaired, it gets replaced.
Pick your term from the protection plan option shown with this product or in your cart. It is entirely optional, and the 12-month manufacturer warranty applies either way. Accidental damage is not covered by this plan.
