Tumble-Bee TB-22 vs KomeStone K1 2026
For a beginner who wants included media and clear loading directions, the KomeStone K1 is the better default; choose the Tumble-Bee TB-22-KIT if two barrels are your priority. The practical choice is a guided single-barrel setup or two separate containers, not a proven difference in finish; see our river-rock tumbler comparison if neither fits.
Two barrels or a guided single-barrel kit?
A practical comparison of documented kit contents and features, not a claim about polishing results.

Verdict
Choose the KomeStone K1 for its included ceramic media and specific loading guidance. Choose the Tumble-Bee TB-22-KIT instead if two barrels and its listed thermal overload protection matter more to your setup.
Which kit is the better fit?
Choose the K1 if you want ceramic media, rough stones, polishing grits, and model-specific loading advice in the same kit. The Tumble-Bee is the better match when two separate 2 lb barrels or its listed motor cutoff matter more. The available details do not establish which tumbler polishes faster or produces a better finish.

How do the setups change the choice?
The main tradeoff is how you want to arrange your batch and how much guidance you want with it. The Tumble-Bee gives you two containers; the K1 pairs one container with more specific instructions and listed supplies. Neither barrel count nor listed capacity proves how a batch will polish.
Two barrels offer organization, not a guaranteed workflow
The Tumble-Bee TB-22-KIT gives you two separate barrels to organize. Think of two small work trays rather than one larger tray: you can keep batches separate, but the listing does not establish whether both barrels can run at the same time. Do not assume a particular workflow from the barrel count alone.
The K1 has one barrel, which may suit you if you prefer to manage a single container. If you are choosing based on batch size, keep the capacity labels in perspective: the Tumble-Bee lists barrel capacity, while KomeStone separately states a maximum rock load for the K1. Neither number tells you how much rough stone comes in the box.
The included supplies start you from different places
The Tumble-Bee kit lists grit and polish along with an instruction manual, lightweight oil, and an Allen wrench. Its acquired listing does not confirm rough stones or ceramic media, so do not count on either being included without checking the package you plan to buy. This kit makes sense if its listed supplies and two-barrel arrangement match what you already have in mind.
KomeStone lists rough stones, four types of grit, ceramic media, spare belts, and a full-color guide for the K1. That gives you more of the stated tumbling materials in one package, but the included rough-stone supply is 1 lb. The manufacturer separately says the K1 holds up to 2.5 lb of stones; that maximum is not the amount of rough included.
The K1 gives specific loading and stone-size advice
For the K1, KomeStone recommends filling the barrel one-half to two-thirds full with rocks and ceramic media, then adding enough water to cover the contents. It recommends stones 1 to 1.25 inches across, with the largest no bigger than 1.5 inches, and advises against pieces smaller than 1/4 inch. That gives you a model-specific starting point if you would rather follow instructions than estimate.
KomeStone says its ceramic media cushions stones and can be reused after thorough washing between stages. The manufacturer recommends replacing it once it becomes smooth or loses its abrasiveness. These are K1-specific directions, not a general loading or maintenance guide for the Tumble-Bee. See KomeStone's K1 FAQ for its recommendations.
Listed protections are features, not performance guarantees
The Tumble-Bee listing describes a thermal protector that shuts off the motor if it overheats, shielded moving parts, and a lighted on/off switch. It also lists a hard composite-plastic housing. Those details tell you what the listing says the unit includes; they do not establish how it will hold up over time or perform in your home.
The K1 FAQ does not establish equivalent motor-protection or housing details. The supplied information also does not give comparable measured noise levels, operating costs, or polishing results for the two models. If one of those details would decide your purchase, confirm it for the exact model and package with the seller or manufacturer.
Which buyer should choose each kit?
Choose based on which details you need before the first batch: the K1 has specific loading directions and listed rough stones and ceramic media, while the Tumble-Bee has two barrels and a listed motor cutoff. If neither setup answers your questions about noise, operating cost, or service, ask the seller or manufacturer to confirm those details before deciding.
Choose the KomeStone K1 if...
Choose the KomeStone K1 if you want one barrel, the manufacturer’s loading and stone-size recommendations, and ceramic media and rough stones in the listed kit. The instructions can help you choose a starting load without guessing at fill level. Remember that the included rough stones weigh 1 lb, even though KomeStone separately states a maximum rock load of up to 2.5 lb.
Skip the K1 if two separate barrels are essential to how you want to sort batches, or if you need confirmed information the FAQ does not provide, such as measured noise for your space. For more model-specific information, see our KomeStone K1 guide.
Choose the Tumble-Bee TB-22-KIT if...
Choose the Tumble-Bee TB-22-KIT if two 2 lb barrels are the feature you need. Its listing also includes grit and polish, an instruction manual, lightweight oil, and an Allen wrench, and describes a thermal overload cutoff and shielded moving parts.
Skip the Tumble-Bee if you need confirmed ceramic media, included rough stones, or model-specific loading and stone-size advice in the product information you have reviewed. The acquired listing does not establish those details. Confirm the package contents and any operating or service information that affects your decision.
When neither kit fits
If a measured noise level or operating cost is essential, neither set of acquired details answers that question. KomeStone’s FAQ states a one-year free parts replacement warranty and a 90-day money-back guarantee for the K1; the Tumble-Bee kit listing does not specify service terms. Confirm current terms for the exact package before buying. If neither barrel arrangement suits your rough, compare other machines by their documented capacity and your available stone supply.
What should you check before starting?
Use the instructions for the exact model you own. Do not transfer the K1’s fill level, stone sizes, or ceramic-media care advice to the Tumble-Bee without confirmation, and check the delivered contents against the listing. These model-specific directions matter because the two kits do not document the same supplies or loading guidance.
Handle tumbling grit carefully. Beginner guidance recommends wearing a face mask when handling grit to avoid inhaling it; see the beginner tumbling instructions. The product cards below identify the two kits, but do not establish comparable noise, finish quality, service terms, or batch timing.

FAQ
Does the Tumble-Bee TB-22-KIT include ceramic media?

Does the KomeStone K1's stated 2.5 lb capacity mean the kit includes 2.5 lb of rocks?
No. KomeStone lists 1 lb of rough stones in the K1 kit and separately states that the K1 holds up to 2.5 lb of stones. One figure describes the included supply; the other is the manufacturer's stated maximum rock load.
What barrel fill and stone sizes does KomeStone recommend for the K1?
KomeStone recommends filling the K1 barrel one-half to two-thirds full with rocks and ceramic media, then adding water to cover. It recommends stones 1 to 1.25 inches across, with the largest no bigger than 1.5 inches, and advises against pieces smaller than 1/4 inch.
Which kit includes two barrels?
The Tumble-Bee TB-22-KIT includes two 2 lb rubber barrels. The KomeStone K1 is listed with one 2.5 lb rubber barrel. The barrel count alone does not establish whether the Tumble-Bee can run both barrels simultaneously.
What noise level, warranty, and replacement-parts support are verified for each model?
The KomeStone FAQ states a one-year free parts replacement warranty and a 90-day money-back guarantee for the K1. The acquired Tumble-Bee kit listing does not specify service terms, and neither source gives comparable measured noise levels. Confirm current terms with the relevant seller or manufacturer.
