Liebherr Prime BioFresh 387L Tall Fridge - Stainless Steel vs 125L Undercounter Fridge with Icebox - White — Comparison

The Liebherr RBSDC525I Prime BioFresh 387L Tall Fridge in stainless steel is the larger, premium option here at £1,399, aimed at buyers who want a full-height larder fridge with advanced freshness storage. The Liebherr RDI1621 125L Undercounter Fridge with Icebox in white costs £499 and sits at the compact end of Liebherr’s range, giving smaller kitchens chilled storage plus a handy icebox.

RBSDC525I is built around a 387L larder-style layout, so it offers far more fresh-food capacity than the 125L RDI1621. It also adds SmartSteel, a Touch & Swipe display, LightTower lighting and dedicated Meat & Dairy Safe storage, alongside a stronger C energy rating. The RDI1621 counters with EasyFresh, SuperCool, an internal LED light, TouchControl and a display lock, but it is D rated and designed for undercounter installation rather than bulk storage.

Choose the RBSDC525I if you do a large weekly shop, cook from fresh ingredients and want premium controls, lighting and drawer management. It is the better fit for families, open-plan kitchens or anyone replacing a main fridge. The RDI1621 suits flats, utility rooms, offices or buyers who need a secondary fridge with an icebox and want to keep the budget well below four figures. In practical terms, think about the appliance’s job before comparing finishes: a tall larder model is usually the main fresh-food hub, while an undercounter, tabletop or specialist cooler works best as targeted extra storage. That context matters because a shared brand, model family or energy label can still hide big differences in usable shelf space, access, installation and how frequently the fridge will be filled. It is also worth checking door swing and available height.

Bottom line: choose RBSDC525I if you want maximum Liebherr fridge capacity, BioFresh storage, SmartSteel styling and a C-rated tall larder design / opt for RDI1621 if you need a compact undercounter fridge with EasyFresh, SuperCool and an icebox at £499.
