Description
Bosch Series 2 Built-In Integrated Under Counter Larder Fridge, 87.4 x 54.1 cm, sliding hinge
A built-in under counter larder fridge holding 136 litres behind a furniture door, with a MultiBox drawer, SuperCool and 35 dB(A) running.
The KIR21NSE0 is Bosch's Series 2 built-in larder fridge, sized for an 880 by 560 by 550 mm under counter niche and fitted behind your own kitchen door. Its 136 litres are all fresh food space, which makes it a good match for a utility room, a small kitchen or a second fridge in an island.
Three safety glass shelves, two of them height adjustable, sit above a MultiBox drawer with a rippled base for fruit and vegetables, and there are two door bins plus a removable door compartment. SuperCool drops the temperature before a big shop, defrosting of the fridge is automatic and running noise is 35 dB(A).
Ideal For
An 880 mm niche is all it needs, so a compact kitchen keeps a proper fridge without giving up a full-height column of cabinet space to it.
At 136 litres and 29 kg it works well as an extra fridge in a utility room or island, taking drinks and overflow away from the main appliance.
A sliding hinge takes your furniture door, so the fridge sits flush in the run of base units with nothing to mark it out as an appliance.
Key Features
Every litre of the cabinet goes to fresh food, with no freezer box, so a small household's weekly shop fits inside a single under counter unit.
A transparent drawer with a rippled bottom holds fruit and vegetables, keeping produce off the glass shelves and away from everything else in the fridge.
Three safety glass shelves are fitted, two of which move up and down, so the layout can be changed for taller bottles or bigger dishes.
Chill the fridge in advance of a big delivery, so newly loaded food comes down to temperature quickly and existing contents are not warmed.
Bosch rates it at 92 kWh per year, class E on the current label, with automatic fridge defrosting and a single compressor doing the work.
A class B noise rating of 35 dB(A) keeps the fridge quiet, which counts when it sits under a worktop in a room people use.
A fridge that stays out of sight
Under counter integrated fridges suit kitchens where a full-height column would dominate, or where the cooking wall needs to stay uninterrupted. This one occupies an 880 by 560 by 550 mm niche and measures 87.4 by 54.1 by 54.8 cm, with a sliding hinge that carries your own door. At 29 kg it is manageable to fit, and the right hinged door can be reversed if the room works better that way.
Making 136 litres work
Space is finite here, so how it is divided matters. Three safety glass shelves, two of them adjustable, let you set the heights around what you actually buy. Below them the MultiBox drawer takes fruit and vegetables in one place, with its rippled base. The door holds two bins plus a removable storage compartment, which is where bottles, jars and cartons live so the shelves stay clear for food.
Simple electronics, quiet running
There is no app and no touchscreen, just LED electronic control on the front, bright LED lighting inside and a door open alarm if it is left ajar. SuperCool is the one function you will use regularly, dropping the temperature before a big shop. Defrosting of the fridge section happens automatically, the interior is designed to be easy to clean, and Bosch quotes 35 dB(A) and 92 kWh a year. The power cord runs to 230 cm.
How It Compares
| Kitchen Need | Bosch Technology | Practical Benefit |
|---|---|---|
| Small kitchen | 880 mm under counter niche | Fits a standard base unit gap, so a proper fridge does not cost you a full-height cabinet. |
| Fresh produce | MultiBox drawer | A transparent drawer with a rippled base gives fruit and vegetables their own place rather than a shared shelf. |
| Bottles and cartons | Two door bins | Door storage plus a removable compartment keeps tall items off the glass shelves and easy to reach. |
| Restocking the fridge | SuperCool function | Lowering the temperature before loading means new food chills quickly without warming what is already inside. |
| Quiet kitchens | 35 dB(A) operation | A class B noise rating means the fridge is barely noticeable in a room used for eating or working. |
| Running costs | 92 kWh per year | Bosch's stated annual consumption, helped by automatic fridge defrosting and a single compressor cooling system. |

The Verdict
Strengths
- 136 litres of fridge-only space, no freezer box
- Three safety glass shelves, two height adjustable
- MultiBox drawer with a rippled base for produce
- Two door bins plus a removable door compartment
- SuperCool function and bright LED interior lighting
- Quiet 35 dB(A) running, noise class B
- Automatic fridge defrosting and a door open alarm
Considerations
- There is no freezer compartment, so frozen food needs a separate appliance somewhere else in the kitchen or utility room.
- It is a fully integrated fridge, so an 880 mm niche and a furniture front are required and fitting is not a plug-in job.
- Rated E for energy at 92 kWh a year, with no interior ventilator and no Home Connect app control.
