Turning a mini fridge into a kegerator is one of the most popular ways to get draft beer at home without buying a full-size dedicated unit. A mini fridge to kegerator conversion kit supplies the tap tower, faucet, coupler, and gas line parts needed to dispense beer from a keg while the fridge keeps it cold. The right kit depends on whether you already own a CO2 tank, how much space your fridge has inside, and whether you want a single tap or a bar-style setup. The six options below were compared on specification clarity, brand reputation, and patterns in owner feedback rather than on hands-on trials.

Our Top Picks
Each pick below was assessed against four criteria: whether the kit is complete for its stated purpose, how clearly the specifications are documented, whether the parts match common keg and fridge configurations, and the recurring themes in owner reviews about leaks, fitting, and included hardware.
Refrigerator to Kegerator Conversion Kit without Tank
Refrigerator to Kegerator Conversion Kit without Tank
Best for: Overall flexibility for a mini fridge conversion when you already have or plan to buy a separate CO2 tank.
This kit suits someone who wants the tower, faucet, and line hardware without paying for gas equipment they may already own. It works best for builders comfortable matching regulator and fittings themselves.
Key specs

- Sold without a CO2 tank
- Requires a separate regulator and gas supply
Pros
- Lets you reuse an existing CO2 cylinder
- Straightforward scope with no unneeded gas hardware

Kegerator Conversion Kit with CO2 Tank (Convert a Refrigerator to a Kegerator)
Kegerator Conversion Kit with CO2 Tank (Convert a Refrigerator to a Kegerator)
Best for: Small kitchens and first-time builders who want a near-complete package in one order.
Owners who want to avoid sourcing a tank and regulator separately tend to favor all-in-one kits. This one bundles the gas side, which simplifies the purchase but adds bulk to a compact setup.
Key specs
- Includes a CO2 tank as part of the kit
- Designed for converting a refrigerator to a kegerator
Pros
- Fewer separate parts to source
- Suitable for a first conversion
- Gas and dispensing hardware arrive together
Cons
- Tank takes up interior space in a mini fridge

Bottom line: A good choice for a small kitchen build if you want everything in one box and can plan around the tank footprint.
Kegco Tap Conversion Kit, Chrome (3PATK)
Kegco Tap Conversion Kit, Chrome (3PATK)
Best for: Budget-minded builders who need the tap hardware and already have a gas setup.
This is a focused tap kit rather than a full system. It suits someone upgrading the dispensing side of an existing conversion or adding a faucet to a current build.
Key specs
- Chrome finish on the tap hardware
- Three-piece tap conversion kit by listing name
Pros
- Lower commitment than a complete system
- Chrome finish is common on home bar setups
- Useful for upgrading an existing tower
Cons
- Does not include gas or regulator components
- Less suitable for a first-time full conversion

Best for: A complete starter setup with a standard tower and a 5 lb CO2 tank.

Best for: Kegs using European Sankey couplers, common on many imported and some domestic kegs.

Buying Guide
Coupler Type
The coupler is what connects the keg to your gas and beer lines. The two most common types are the standard US D-type and the European Sankey D-type. Mismatched couplers are the most frequent cause of leaks and failed fittings, so confirm your keg type before ordering.
Good picks for this: Standard Refrigerator Conversion Kit (European Sankey Coupler – No CO2 Tank), Refrigerator to Kegerator Conversion Kit without Tank
Whether the Kit Includes a CO2 Tank
Some kits bundle a tank and regulator, while others expect you to supply them. Bundled kits simplify purchasing but take up interior space. Tankless kits give you flexibility if you already own gas equipment.
Good picks for this: Kegerator Conversion Kit with CO2 Tank (Convert a Refrigerator to a Kegerator), BACOENG Standard Tower Kegerator No Tank Beer Conversion Kit
Fridge Interior Size and Tower Height
Mini fridges vary widely in internal height and depth. Measure the clear height inside the cabinet, then add the tower height and the tap handle clearance. Many owners find that a tower which looks fine in a listing will not clear a shelf or door once installed.

Tank Size and Gas Capacity
A 5 lb CO2 tank is compact and suits small fridges, but it holds less gas and needs refilling more often. Larger tanks last longer but need more room. Plan around how often you will pour and how much space you can spare.

Tap Hardware and Finish
Faucet material and finish affect both appearance and cleaning. Chrome is common and generally easy to keep clean. Check that the faucet thread and shank length match your tower before assembling.

Build Experience and Included Parts
Beginners usually benefit from kits that include regulators, fittings, and clear instructions. Experienced builders often prefer tankless or tap-only kits so they can reuse existing gear. Read the parts list closely to avoid buying duplicates.

Cleaning and Maintenance
Beer lines and faucets need regular cleaning to prevent off-flavors and buildup. Choose a kit whose tap and line components you can disassemble and clean without special tools. Plan on cleaning lines at each keg change.

FAQ
Can any mini fridge become a kegerator?
Most mini fridges can be converted if the interior is tall enough for the keg and tower and the compressor can hold a steady cold temperature. Check the internal height, door clearance, and whether the fridge has a thermostat that can be set low enough for beer.
Do I need a CO2 tank for a mini fridge conversion?
Yes, a CO2 supply is needed to push beer from the keg to the faucet. Some kits include a tank, while others expect you to provide one. Either way, you will need a regulator to control pressure.
What keg size fits in a mini fridge?
Many mini fridges fit a 5-liter mini keg or a Cornelius-style keg depending on height and diameter. Measure the keg and the interior before purchasing, and check the tower height against the cabinet.
How do I keep beer from foaming at the tap?
Foaming usually points to temperature, pressure, or line length problems. Keep the fridge cold, set the regulator correctly for the beer style, and use a line length suited to your pressure. Our related guides cover these fixes in more detail.
Do I need a regulator with a tankless kit?
Yes. A tankless kit assumes you have a CO2 tank and a regulator. The regulator controls the pressure delivered to the keg, so buy one rated for your tank and compatible with the fittings in the kit.
Is a conversion kit safe to install myself?
Many home builders complete conversions successfully, but gas and electrical work carry risk. If you are unsure about gas fittings or electrical connections, consult a qualified professional before installing.
Conclusion
For most home bars, the Refrigerator to Kegerator Conversion Kit without Tank is a flexible starting point if you already own a CO2 tank. Builders who want a complete package in one order should look at the Kegco BF STCK-5T or the all-in-one CO2 kit, keeping tank size and fridge height in mind. The European Sankey kit suits owners whose kegs match that coupler, and the BACOENG kit fits experienced builders with existing gas gear. Measure your fridge and confirm your coupler type first, and your conversion will be far easier to get right.
