​You know how they say “waste not, want not”, right? Well, what is a better way to stick to that than by making use of the waste from your home and turning into something that can help you grow a wide variety of healthy plants?

Compost is an incredibly simple way to boost the nutritional value of the soil you use to grow vegetation, whether it is fruit, vegetables or just any other plant life. Creating compost is a bit of a task that you cannot take lightly. Turning garbage into a useful material for soil requires preparation and the right equipment. The most vital aspect to creating good compost is a proper compost tumbler.

Whether you are someone new to the world of composting or you have been doing it for a while, you know how important it is to get the right compost tumbler. Of course, finding the best compost tumbler can be quite an overwhelming task. You could even say that it stinks .. just as much as a pile of compost does itself. Don’t worry though – we’ve got you covered.

We have put together this guide to reveal the best compost tumblers in the market right now so you can narrow down your choices and make the best buying decision for a new compost tumbler.

Spoiler alert - our favourite is the ​​FCMP Outdoor IM4000.

If you're on a budget, the ​Riverstone Industries RSI-MCT-MC might be a good option.

​The Best Compost Tumblers In 2019 - Comparison

We understand how difficult it can get to find the right compost tumbler for your use. This is the reason why we have tried and tested out a lot of the top compost tumblers in the market to help you decide which one is truly the best.

#1 - ​FCMP Outdoor IM4000- Our Choice

The ​​FCMP Outdoor IM4000 is the best ​compost tumblers we have seen. Unless you are a commercial gardener, we believe this is the ​compost tumblers for most people.

IM4000 Dual Chamber Tumbling Composter (Black)


  • ​Item Weight:     26.5 pounds
  • Item model number:     IM4000
  • Manufacturer:     Forest City Models and Patterns Inc
  • Shipping Weight:     26.7 pounds

We are going to start off the guide with our own choice of the best compost tumbler. Aptly at the top is the FCMP Outdoor IM4000 Tumbling Composter. FCMP Outdoor is among the first companies that started producing compost tumblers at a time when people with a green thumb did not even realize how much easier preparing compost can be. The experience that FCMP Outdoor has in the industry is clear when you take a look at this 37 gallon IM4000 model.

This is more than a decent sized compost tumbler and it has a whole host of features, which makes it our first choice as one of the best. You can rely on getting high quality compost every time with this. The 37 gallon capacity comes through two separate compartments within the compost tumbler, which holds 18.5 gallons each. You can leave a heap in one section to decay while you fill up the other section with more.

The two heap system allows you to get continuous access to fresh compost. You will not need to struggle with everything that comes with opening and closing the compost chamber doors that messes up the process of decay.

According to the manufacturer, all you need is the right ingredients (a good pile of garbage) filled up within the compost tumbler, an ample amount of sunlight and a couple of weeks. You can get the perfect compost heap every time with this in such a small amount of time.

There are plenty of holes to let the air in and aid the decomposition process. The octagonal shape of the chambers also keeps the compost from sticking to the sides of the chamber as you turn it from time to time. Both of these factors come in handy to ensure a good amount of oxygen getting through to all of the compost mix.

You get plenty of space to add the ingredients to the chambers. Everything from kitchen waste to emptying out the grass cuttings from the lawnmower’s basket is a breeze. You can turn the compost tumbler easily using the handle or just by turning the barrel from the sides.

FCMP Outdoor did a really good job with the construction material. It is essentially a plastic, but the polypropylene is BPA-free, so you will not need to worry about any chemicals becoming a part of the compost heap you are preparing with this. The thick plastic also makes the compost tumbler durable, which will last you a very long time come rain or shine.

The best part about it all is that it is made completely from recycled material, which makes the product a lot more environmentally-friendly than what you can expect from standard plastic products.

Minor Issues

As with all cordless yard tools, there are a couple of disadvantages to be aware of:

People might find 18.5 gallons per compost heap pile to be too short for the ingredients to reach critical mass. You might also need some help from another person while assembling it since it is not that easy. The seams let the water in a little too easily for the liking of some people.


While you can rely on the IM4000 to give you a lasting compost heap production, it is always a good idea to know the warranty period of anything you buy. In order to find out the warranty, you should contact the manufacturer on their website to request it.

#2 - EJWOX Composting Tumbler

Good value trimmers, from a lesser-known manufacturer


  • ​Manufacturer Part Number    3001
  • Assembled Product Weight    24 lbs
  • Material    Recycled Plastic, Steel
  • Assembled Product Dimensions (L x W x H) 28.00 x
  • 26.00 x 37.00 Inches

Garden Compost Bin from BPA Free Material, Dual Rotating Outdoor Composting Tumblers (43 Gallon,Black)

Slightly larger than most of the models that you can get in the market right now, the EJWOX is the second entry on our list. The 43 gallons of capacity divided between two chambers is just one of the qualities that this compost tumbler brings to the table.

The chamber has a black color to help absorb as much of the sun’s heat as possible to speed up the decomposition process. The doors of the compost tumbler by EJWOX are also pretty good when it comes to keeping all kinds of rodents out of the chambers, so you can leave it be without a worry.

The chambers on the EJWOX model also close up tightly to keep a waterproof seal, which means you do not need to worry about any additional water seeping into it to create a wet mush instead of useful compost even if the skies open up and pour like cats and dogs. You also don’t need to worry about having to make additional efforts to hold the chambers in one place since there is a locking mechanism that does it for you.

One of the best things about the EJWOX is the fact that the plastic used to make it is completely BPA-free. This gives you peace of mind knowing your compost will not be contaminated with any chemicals, which would otherwise seep into it. Whatever you grow using the compost heap prepared with the EJWOX will be completely free of chemical contaminants coming from plastics.

Minor Issues

Small problems don't need to be deal-breakers

Even though this is one of our top picks among the best compost tumblers you can get, not everything about the EJWOX is perfect. The assembly process of the EJWOX compost tumbler is tough for someone doing it alone. You might also find it hard to fit in the divider between the two chambers of the compost tumbler.


EJWOX is a company that prides itself on the quality of the products they produce. They have a 100% refund or replacement guarantee for any of the products that they produce. If it starts giving you trouble, you can claim the warranty. The only thing you will need to worry about is the cost of postage.


  • ​Lifetime warranty
  • BPA-Free material
  • ​higher capacity


  • ​Difficult to assemble
  • ​Divider is difficult to place
  • ​Airflow vents connect the two chambers

#3 - ​Envirocycle FBA_PR062

A more compact cordless model

No products found.


  • ​Product Dimensions     19 x 18.8 x 21.5 inches
  • Item Weight     13.8 pounds
  • Shipping Weight     17.77 pounds
  • Manufacturer     Envirocycle

As the name suggests, the Envirocycle model in the list really is the cutest composter you will ever come across. This is the perfect compost tumbler to have if you are looking for a compact composter. At a very miniscule 21.5 inches of height, this is a very short compost tumbler, which sits directly on the floor.

There is just one chamber on it and it boasts a pretty modest capacity of just 17 gallons, so you cannot rely on this for constantly adding fresh compost without interruption. The reason why this makes it on the list of the best compost tumblers in 2019 is the fact that it is an innovative product.

The dual system in the Envirocycle produces two different types of compost at the same time. The liquid matter that is produced by the compost tumbler can be separated and removed to extract what can be called compost tea. You can use this separately from the traditional and solid compost.

 There is a large enough opening for a shovel, so its low height makes it easier to load with ingredients and unload it when the compost is ready. This BPA-free composter is made from recycled materials to keep the impact on the environment to a minimum.


  • ​Height makes it easy to use
  • ​Creates two different types of compost
  • ​BPA-free and recycled material production


  • ​Too small for most applications
  • ​Interrupted supply of compost
  • ​Just one chamber to produce compost

#4 - ​DF OMER Miracle-Gro

Lightweight corded option


  • ​Package Dimensions     26.2 x 22.2 x 6.6 inches
  • Item Weight     23.4 pounds
  • Shipping Weight     23.4 pounds
  • Manufacturer     DF OMER

Large Dual Chamber Compost Tumbler – Easy-Turn, Fast-Working System – All-Season, Heavy-Duty, High Volume Composter with 2 Sliding Doors - (2 – 27.7gallon /105 Liter)

Miracle-Gro is not just your average manufacturer of composters; they pride themselves on being plant growing aficionados. That is evident with their Large Dual Chamber Compost Tumbler. One of the best compost tumblers in 2019, let’s a look at what makes it a part of this list.

Dual chambers allow you to add material to the second chamber while the compost is getting ready in the first one. The shape of the compost tumbler is hexagonal to keep the compost from sticking to the sides of the barrel.

The doors on the Miracle-Gro Large Dual Chamber Compost Tumbler are sizable to allow you to load the ingredients and unload the compost easily. Each chamber turns individually and you can remove the compost without a problem once it’s ready.

Just avoid adding too much moist material into the composter because the doors do not create the best seal, which can cause leakages with a horrible odor when you turn it. You don’t need to worry about holding the composter in position. The locking mechanism prevents the chambers from turning on their own and keeps it steady as you need it.

 There are paddles within the chambers, which help prevent the compost from clumping together and keep the airflow through the ingredients just right.


  • Versatility
  • ​BPA-free construction
  • ​Independently rotating dual chambers


  • ​Flimsier than most other models
  • ​Doors do not provide a good seal
  • ​Assembly is very difficult

#5 - ​Riverstone Industries RSI-MCT-MC

Compact and powerful

RSI MCT-MC Maze Compost Tumbler, Black


  • ​Product Dimensions     30 x 41.3 x 44.5 inches
  • Item Weight     65.3 pounds
  • Shipping Weight     65.3 pounds
  • Manufacturer     Riverstone Industries

The last entry on our list of the best compost tumblers in 2019 is the Two Stage Cart Compost Tumbler by Riverstone Industries. A beautiful looking compost tumbler, this unit also features two chambers so that you can have a constant supply of fresh compost.

It features a large clearance area underneath the two chambers, so you can unload it easily by turning it over. You also get a free cart with the unit that allows you to transport the compost you have prepared easily.

The handle on the compost tumbler makes it very easy to turn even when it is filled to complete capacity. It also means you get to mix the compost ingredients well and ensure proper airflow for steady production of compost (with a fantastic 65 gallon capacity).

 It is a long lasting compost tumbler made from a rust-resistant material and it is good at protecting the compost heap from rodents or any other animals that might try to get access to the heap inside.


  • ​Long-lasting construction
  • ​Easy to turn
  • ​Large clearance area underneath the chambers


  • ​It is a very expensive compost tumbler
  • ​Assembling takes a lot of time and effort
  • ​Screws will rust

What Makes A Good ​Compost Tumbler?

Our buying guide will make sure you're informed before you decide which model is best for you.

We did not just want to narrow down the list to the few we consider the best, we reviewed them so that you can also understand why they are our top picks. As you might have noticed, each of them has different qualities that they bring to the table despite having the same basic function.

We’re going to take a look at some of the qualities you need to consider that can help you decide how to pick the best one for your needs.


Rounded tumblers are easy to tumble. They don’t have cold spots due to even distribution, but the compost tends to stick to the sides. Octagonal or hexagonal bins in the compost tumblers make sure that the compost doesn’t stick to the sides, but you need to be mindful about turning it to keep the heat distribution even throughout the mix.


The decaying process relies heavily on a good amount of oxygen. The compost tumbler you consider needs to boast good ventilation.

Number of Chambers

It’s better to have a compost tumbler with two chambers if you need an uninterrupted supply of compost. You can add ingredients to one chamber while the compost is getting ready in the other chamber.


The material used to make the bin is essential. The construction has a direct impact on the compost process. You need something made with a dark color and recycled material. This helps reduce the amount of time taken since the darker color absorbs more solar energy. Recycled material keeps the environmental low by reusing already existing plastic material.


A few pointers to help you stay safe when using your trimmer

Safety is always a matter of concern when you’re using any kind of gardening equipment – even a composter. Make sure you wear all the right protective gear to cover you while you unload the composter’s chambers so that you do not end up smelling bad.

Make sure you use the tumbler for nothing more than what it is intended for and make sure you know how to handle the composter if you are filling up a large capacity unit because it can get very heavy.

One more thing: avoid using a compost tumbler indoors because when you open the doors of a cooked compost, the stench is going to stay indoors for a very long time unless you have fantastic ventilation in your home.

Maintenance / Cleaning

Tips to make your hedge trimmer last as long as possible

Make sure that you keep maintaining the compost tumblers. Even the best compost tumbler can become problematic if you don’t take care of it.

Cleaning them from the inside is never going to be a concern, but make sure you give it a good wipe down from the outside every time you unload it so that none of the horrible smelling compost that has stuck to the exterior can create a bad smell all the time. Be very careful when adding the ingredients and removing the compost, so you do not spill any of it.

As the compost forms, the volume of the solid material decreases, but that does not mean you should add more ingredients to it and overburden it. Fill it up to a reasonable amount and let nature take its course as it should. Overburdening the tumbler can cause damage to it.

We hope you have all the information you need to make the best purchasing decision for the compost tumbler that will be perfect for your needs.


Occasionally faults are discovered after a product has gone on sale, usually requiring the product to be recalled by the manufacturer.

There were no recalls listed for any of the hedge trimmers mentioned here at the time of writing (August 2019). However, it's always a good idea to check the latest information at the Consumer Product Safety Commission website before buying any large, expensive or potentially dangerous product.
