There is no supported universal “best” compost tumbler for every yard, and the available product information does not establish a comparative winner for 2022. The right choice depends on how much material you compost, whether you want to manage one batch or keep adding scraps, and whether you can comfortably turn a loaded drum.
One concrete option is Exaco’s Mr. Spin, which the manufacturer currently describes as a 43-gallon, dual-chamber tumbler. That current specification does not prove it had the same capacity in 2022 or that it was the best model then. Use the criteria below to judge whether a tumbler—and this example in particular—fits your yard and working habits.
What makes a compost tumbler the right choice?
A tumbler is an enclosed bin that rotates so its contents can be mixed and aerated. That can make turning more straightforward than using a fork in a stationary pile, but it does not remove the need to balance materials, manage moisture, or wait for compost to mature. Nor does rotation guarantee a particular finishing time or temperature.
Consider a tumbler if you have a manageable amount of kitchen scraps and yard material, enough room for the unit, and the ability to rotate it regularly. If you generate substantial yard trimmings or expect a wet, heavy drum to be difficult to turn, compare a stationary bin, a pile, or a multi-bin system before buying. The U.S. EPA describes these as different approaches to home composting in “Approaches to Composting.”
#1 Best Overall
- Twin chambers: Two separate chambers allow one side to finish composting while leaving the other side available to add fresh wastes; Constant alternation of the two sides will create an uninterrupted stream of nutritious compost
- 360⁰ Tumbling Design: The rotating design prevents you from digging or mixing the pile by hand; And the deep fins on eight panels make it easier to turn the compost bin
- Excellent Aeration: Air vents can make the air fully circulate and will not cause an explosion due to excessive internal pressure; Deep fins can better break the clumps, which is conducive to the full fermentation of oxygen
- Sturdy & Durable Construction: Constructed of premium metal frame and high-quality pp plastic body, this tumbling composter is corrosion-resistant, weathering-resistant, sturdy, and durable for long-lasting service life
- Garden Gloves Included: The gloves that not only protect your hands from injury, but are also waterproof, making them easy to clean; With 4 durable ABS plastic claws for easy digging, planting and other gardening work
Choose a chamber layout for your composting workflow
| Layout | How it works | Best fit | Trade-off |
|---|---|---|---|
| Single chamber | Add material to one batch, then let that batch mature. | A person who tends to collect material over a short period and can pause additions while it matures. | Adding fresh scraps to a batch that is already maturing can make it harder to manage as one finished batch. |
| Dual chamber | Fill one side while the other side matures, then alternate. | Someone who wants to keep adding material while keeping older compost separate. | Two chambers help organize ongoing batches, but they do not make either batch mature instantly. Wet, heavy loads can also be difficult to turn. |
The Environmental Protection Agency Ireland’s 2017 composting booklet discusses the dual-chamber workflow and the difficulty of turning wet loads. A two-chamber design is useful for batch separation, not a promise of faster compost.
Size the tumbler by usable load, not the advertised capacity
Estimate the material you expect to add, the space available for the unit, and how much weight you can rotate. Published drum capacity is not the same as a practical working load: the EPA-hosted “USDA Fact Sheet: Composting Dog Waste” advises leaving room for mixing and says tumblers should be no more than about half full. Treat that as the guidance in that document, not a guarantee for every model.
Rank #2
- ✅Speed Up Composing Process: More advanced models use rotating to bring oxygen to the center of the bin and paddles inside the chamber to help mix and aerate the composting materials when turned. These improvements or modifications are designed for one reason: to speed the composting process.
- ✅How do Compost Tumblers work? Simple. You load them with green and brown waste from your yard and kitchen. When full, you give them time to work, in other words, heat up. Turning a compost pile mixing the organic materials and the organisms it contains with heat-producing oxygen is the traditional method of keeping the process going full steam. By turning the tumbler, the organic materials are mixed and infused with fresh oxygen.
- ✅Easy to Access Finished Compost: Just Slide the door open and take the organic fertilizer out when the compost is ready. When a check reveals the compost is complete —and this can happen in a matter of weeks —the same access that allowed you to fill the tumbler lets you empty it. Now is the time to spread the results.
- ✅Dual-Bin Design: The dual bin design takes a different approach to the continuous-use composted concept, Two bins are set side-by-side into a single rotating chamber. Thickly insulated compartments conserve the heat generating by the decaying matter, and this greatly speeds the process. This design also allows you to add food waste to one chamber while the other is composting.
- ✅Totally Organic and Money-Saving: If you're looking for a fast, convenient way to compost your kitchen throw-outs, grass clippings, and organic yard waste, our outdoor kitchen compost bin is just right for you! The Compact Compost Tumbler quickly recycles it into nutrient-rich compost.
There is no established household-size-to-gallon rule in the cited guidance. A smaller household can still generate bulky yard waste, while a larger household may compost only a modest amount. Choose for your actual stream of material and ability to turn it, rather than relying on household size alone.
Check turning effort, access, and placement
- Turning effort: A full drum can weigh substantially more when its contents are wet. The EPA-hosted fact sheet warns that tumblers may be harder to rotate than they appear; the Ireland EPA booklet likewise notes the challenge of wet, heavy loads. Consider your strength and the unit’s handle or crank design, and leave room for the material to tumble.
- Door security: Check that the access hatch stays shut as the drum turns. Bob Vila’s “The Best Compost Tumblers” reported that sliding doors on its evaluated Exaco sample sometimes opened during rotation. That is one publisher’s reported evaluation, not an independent test of every unit or a confirmed finding about current revisions.
- Loading and unloading: Look at the hatch opening, how high the drum sits, and whether you can remove finished compost without awkward scooping. These details can matter as much as nominal capacity.
- Yard fit: Check the footprint and placement in relation to access, exposure, and pest concerns. Do not treat a manufacturer’s insulation or temperature statement as independently verified performance.
A cited example: Exaco Mr. Spin
Exaco currently describes the Mr. Spin as a 43-gallon dual-chamber tumbler with adjustable vents, recycled-plastic components, and an 18-gauge tubular-steel frame. Its product page lists dimensions of 28 inches wide by 37 inches high and a weight of 24 pounds. These are manufacturer-listed specifications, and the page does not establish that the same specifications applied in 2022.

The dual chambers may suit someone who wants to keep a maturing batch apart from new additions. Before choosing this model, assess whether the actual load will be manageable to turn and whether its doors and unloading access work for your situation. Bob Vila’s reported sliding-door issue is a reason to inspect the specific unit and its current design; it is not enough to establish a defect across all versions.
Jora offers a different, insulated-tumbler approach and lists models in different capacities. Its performance statements are manufacturer claims, not an independent comparison. The available evidence does not support naming a Jora model, Exaco Mr. Spin, or another tumbler as the best choice for every yard—or as a verified 2022 winner.

Use the tumbler well: balance browns, greens, air, and moisture
A rotating drum is only one part of composting. The U.S. EPA’s “Composting At Home” guidance calls for carbon-rich “browns,” nitrogen-rich “greens,” air, and moisture. It suggests using at least two to three volumes of browns for each volume of greens, covering food scraps with dry browns, and aiming for moisture like a wrung-out sponge. These are general home-composting recommendations; adjust to the materials and conditions in your drum.
- Chop tough material into smaller pieces to help it break down.
- Mix or rotate material to introduce air, while leaving room for it to move inside the drum.
- Check moisture rather than assuming an enclosed bin will stay at the right level.
- Follow local rules and the instructions for your specific system.
EPA guidance advises against putting meat, fish, bones, dairy, fats, oils, or grease in ordinary backyard compost because of pest concerns and insufficient temperatures. It also lists pet waste, treated or painted wood, aggressive weeds, and diseased plants among materials to avoid. EPA’s broader overview says home systems mostly handle food scraps other than meat, bones, and dairy, along with yard trimmings. Local requirements and product instructions still matter.

A tumbler may be a poor match if your yard produces more bulky material than you can comfortably load and rotate, or if you do not want to manage a turning drum. A stationary enclosed bin or multi-bin setup may better fit that volume or workflow. A conventional pile is another option, though EPA guidance describes turning it with a garden fork; a fork is not required for a tumbler.
For a practical decision, first estimate your recurring kitchen and yard material, then decide whether you want one batch at a time or alternating batches. Compare the usable load, turning effort, access, and footprint of the specific unit—not just its capacity label. If the evidence available for a model does not establish its 2022 specifications or comparative performance, treat it as an option to assess, not a historical winner.
