A conversion kit can be a genuine budget option, but it shifts the compatibility burden onto whatever fridge is being converted.
A purpose-built kegerator is sized for the job from the start
A dedicated kegerator’s interior, door clearance, and CO2 routing are engineered around keg dimensions specifically — no guesswork about whether a keg will actually fit.
A conversion kit depends entirely on the donor fridge
Converting a mini fridge means checking its interior height and width against the keg format intended, and drilling or routing a CO2 line through the cabinet — a real DIY step with real fit risk if the fridge wasn’t chosen with this in mind.
Warranty implications are worth considering
Modifying a mini fridge to add a tap and CO2 line typically voids any remaining fridge warranty, which a purpose-built kegerator’s own warranty doesn’t carry the same risk for.
What to check before choosing a conversion
Measure the specific fridge’s interior against the intended keg format precisely before committing to a conversion kit, and check whether a comparably priced purpose-built compact kegerator might avoid the fit risk entirely.
What we would not do
Recommend a conversion kit without first confirming the donor fridge’s interior dimensions genuinely accommodate the keg format intended — this is the single most common way a conversion project stalls partway through.
