10 Best Compost Tumblers 2025 in the United States

The THEGROW'ING 43 Gallon Compost Bin is a solid choice for gardeners looking to speed up composting without taking up too much space. Its 43-gallon capacity is generous enough for most backyard needs while still having a compact footprint that fits well on patios or smaller yards. The dual-chamber feature is a big plus, allowing you to compost continuously by filling one side while the other breaks down — this keeps your compost process moving without waiting. Made from BPA-free polypropylene plastic with a sturdy powder-coated steel frame, this bin is built to resist outdoor weather like rain and wind, so it stands up well over time without cracking or rusting.

The internal air vents and a rotating design help oxygen reach the scraps, which means your compost breaks down faster, often ready within weeks. Setting it up is easier than many other models thanks to an innovative nut system that doesn’t require holding nuts in place, making assembly quick even for beginners. On the downside, at about 21 pounds, it’s not the lightest compost tumbler, so moving it around when full might be tough. Also, while the 43 gallons suit most small to medium gardens, very large gardens or heavy compost users might want a bigger capacity. Some users note the bin’s hexagonal shape might affect how much waste you can fit compared to round barrels.

This composter offers great convenience, durability, and efficiency for anyone looking to maintain a regular compost routine in a modest space, especially for those new to tumbling compost bins.

The MAZE Two Stage 65 Gallon Compost Tumbler is a comprehensive composting solution designed to make composting easier and more efficient. One of its major strengths is its large 65-gallon capacity, which is suitable for bigger households or avid gardeners who generate a fair amount of compostable waste. The tumbler is made from UV-resistant, high-impact plastic, ensuring durability and longevity, even when placed outdoors. The extra-large double doors and geared handle make it user-friendly, allowing for easy loading, turning, and unloading of compost, all of which are crucial for maintaining an effective composting process.

The built-in adjustable air vents help regulate the aeration, which is essential for the breakdown of organic materials. Its dual-chamber design allows for continuous composting because while one chamber is filled with new material, the other can be curing. This feature is highly beneficial for an ongoing composting cycle without any downtime. However, the size and footprint of this tumbler, measuring 41.3” W x 30” D x 44.5” H, may be a drawback for those with limited outdoor space.

It also comes with a 12-gallon compost cart, a 1.85-gallon kitchen caddie, and 60 compostable corn bags, which add value by making the collection and transfer of compost more efficient. The plant caddie is a nice bonus for those with hanging plants, making it easier to manage and water them. In conclusion, the MAZE Two Stage Compost Tumbler is perfect for serious composters who have sufficient space and are looking for a durable, easy-to-use composting system with added conveniences.

The FCMP Outdoor IM4000 Dual Chamber Tumbling Composter is an excellent choice for both gardening enthusiasts and those new to composting. With a capacity of 37 gallons, it offers a good amount of space for kitchen and yard waste, making it suitable for small to medium-sized gardens. One of its standout features is the dual chamber design, allowing you to work on one side while the other side is composting, which helps maintain a steady supply of ready compost.

This composter is made from 100% recycled plastic, which is a bonus for environmentally conscious users. The tumbling mechanism makes it easy to mix compost without the need to dig by hand – simply turn it a few times every few days. The aeration holes and deep fins facilitate excellent air circulation, essential for quick decomposition, which can lead to compost ready in as little as two weeks under the right conditions.

Ease of use is another highlight. The large openings and removable door simplify the process of adding scraps and extracting finished compost. It’s designed with beginners in mind, making it an accessible option for anyone looking to get started with composting. Its 27-pound weight may make it less portable, and some users may find it a bit bulky for smaller outdoor spaces. Additionally, while the dual chamber feature is beneficial, it does require some coordination to manage the two sides effectively. The construction is durable, but being made from plastic, it's important to keep an eye out for wear over time, especially if exposed to direct sunlight for long periods. The FCMP IM4000 is a user-friendly, efficient composter that suits a variety of users, from beginners to seasoned gardeners, while providing a sustainable solution for organic waste.
