A countertop oven is a freestanding appliance that sits on your kitchen counter to bake, toast, and broil without the need for construction or fixed installation. With capacities ranging from 10 to 60 liters and power outputs of 800 to 2,200 W, it is the portable alternative to a traditional built-in oven for those seeking flexibility, savings, and immediate usability.
The built-in oven is the default choice in most kitchens, but it is not always the most logical one. For rental apartments, small kitchens, secondary residences, or simply to avoid turning on a 70-liter appliance just to toast two slices of bread, the countertop oven has moved past being a makeshift solution to become a highly rational purchase. In this guide, you will see exactly what it is, how it differs from a built-in model, when it pays to switch, and how to choose the right one for your needs without making a mistake. Data regarding models, liters, and power are taken from actual product sheets in the Merkimarket oven catalog.

What a countertop oven is and how it differs from a built-in one
A countertop oven (also known as a toaster oven or mini-oven when it has a low capacity) is a complete appliance that cooks using electric heat inside a closed housing, just like a large oven, but in a compact format that does not need to be built into furniture. You simply place it on a stable surface and plug it into a standard outlet to start using it.
The essential difference from a built-in oven is not what it cooks, but how it is installed and its size. A built-in unit occupies a fixed 60 cm space and is part of the kitchen cabinetry; the countertop model is movable, lightweight, and can be taken from one house to another or stored when not in use. In exchange for that flexibility, the countertop model offers fewer liters and, in basic models, less temperature precision. The good news is that current mid-range models include convection and features that, years ago, only built-in ovens had.
Countertop oven vs. built-in oven: comparison table
Placed side-by-side, each format has different strengths. This table summarizes the differences that truly matter when deciding:
| Criteria | Countertop oven | Built-in oven |
|---|---|---|
| Installation | None: just plug it in | Requires cabinet cutout and mounting |
| Typical capacity | 10-60 liters | 60-75 liters |
| Mobility | Portable, can be moved and stored | Fixed, part of the kitchen |
| Power | 800-2,200 W (230 V outlet) | 2,000-3,500 W (often needs a dedicated line) |
| Approximate price | From ~€33 to ~€130 | From ~€150 and up |
| Ideal for | Rentals, small kitchens, occasional use, second homes | Fixed kitchen, families, intensive daily use |
When a countertop oven (truly) replaces a built-in one
It is not a matter of personal preference, but of fit for your situation. The countertop model becomes the most sensible choice in any of these cases:
You rent or move often. A built-in oven stays in the kitchen; a countertop one goes with you. For furnished apartments without an oven, it is the solution that avoids construction and disputes with the landlord.
Your kitchen is small or lacks a dedicated oven space. When there is no free 60 cm cabinet, or you want to keep it for storage, a 23-30 liter countertop model fits on the counter and handles most daily recipes.
You cook for one or two people. Turning on a 70-liter oven to gratin a small tray is a waste of energy. A smaller-volume appliance reaches temperature faster and consumes less energy per use.
You need a second oven. During family meals or at Christmas, having an extra oven on the counter solves the classic problem of everything needing to go into the oven at once.
If, conversely, you cook daily for a large family and use large trays, the built-in oven remains superior in capacity and uniformity. In that scenario, it is worth reviewing our guide to built-in ovens: functions, pyrolytic cleaning, and measurements beforehand.
Capacity: how many liters do you need
Liters are the first filter and the one that most influences what you will be able to cook. For reference, based on the formats you will see in the catalog:
- 10-12 liters: Compact models like the Bake&Toast 1090. Perfect for toasting, heating, browning small portions, and defrosting. For individual or supplemental use.
- 23-26 liters: The "sweet spot" for one or two people. Fits a medium pizza or a small tray; models like the Bake&Toast 2300 (23 L) or the 26 L model with a pizza stone cover almost everything.
- 30-46 liters: Now you can fit a whole chicken with a rotisserie and medium-sized trays. The Bake&Toast 4600 (46 L, 2,000 W) is a good balance between capacity and space.
- 60 liters: The high-end of countertop models, such as the Bake&Toast 6090 (2,200 W, rotisserie). It approaches the size of a small built-in oven and works for roasts and large trays.
Power, functions, and consumption
Beyond liters, three details make the difference between an appliance that just toasts and one that truly cooks:
Convection (forced air). A fan distributes heat uniformly, browns food better, and reduces cooking times. This is the feature that is most noticeable compared to a basic toaster and the one that brings results closest to those of a built-in oven.
Rotisserie. Present in models of 30 liters and up, it allows you to roast chickens and meats by rotating the item for homogeneous browning. If you like roasts, it is an extra that is worth it.
Double glass, quartz elements, and interior light. Double glass improves insulation and safety; quartz elements heat up faster; and the interior light lets you monitor cooking without opening the door and losing temperature.
Regarding consumption, the power (from 800 W in compact units to 2,200 W in large ones) indicates energy draw at full performance, but the actual cost depends on usage time. Precisely because of its smaller volume, a countertop oven usually preheats faster and, for small meals, consumes less than turning on a large built-in one. To compare appliances logically, learn how to read the energy label and how much you really save.
How to choose your countertop oven in 6 steps
- Define how many people you cook for. One or two: 10-26 liters. Three or four: 30-46 liters. More, or frequent roasts: 60 liters.
- Measure your countertop. Check the available width and depth and leave a few centimeters of clearance on the sides and back for ventilation.
- Decide if you want convection. If you are going to bake and roast, rather than just toast, prioritize a model with forced air.
- Evaluate the rotisserie. If you roast chickens or meats, choose one with a rotisserie (starting from 30 liters).
- Check safety and comfort. Double glass, non-slip feet, timer with automatic shut-off, and a crumb tray make daily life easier.
- Confirm availability and warranty. Verify stock and remember that you have the legal three-year warranty for consumers in Spain.
With these steps clear, you can compare specific models in the oven catalog. Two references that illustrate the range well are the 23-liter multifunction toaster oven for daily use and the Bake&Toast 4600 46-liter countertop oven for those who want more capacity and a rotisserie.
Installation, safety, and maintenance
"Installation" comes down to placing it correctly: on a stable, heat-resistant, level surface, away from curtains and high cabinets, and leaving free space around it so it can vent heat. Do not build it into a closed cabinet or cover it while in operation. Plug it into a wall outlet in good condition and avoid thin extension cords or overloaded power strips.
For maintenance, always let it cool down before cleaning. Remove the tray and rack and wash them separately; the interior should be cleaned with a damp cloth and mild soap, without abrasive products or metal scourers that scratch the enamel. Emptying the crumb tray frequently prevents odors and smoke. A clean appliance not only lasts longer: it also cooks better, because burnt residue affects flavor and heat distribution.
Frequently asked questions about countertop ovens
Can a countertop oven replace a built-in oven?
For one or two people, small kitchens, or occasional use, yes: a 23 to 46-liter model with convection covers most recipes. For large families, large trays, or intensive daily use, the built-in oven remains superior in capacity.
How many liters do I need in a countertop oven?
As a guideline, 10-26 liters for one or two people, 30-46 liters for three or four, and 60 liters if you do roasts or cook for more people on a regular basis.
Does a countertop oven consume a lot of energy?
Its power ranges from 800 to 2,200 W. Being smaller, it preheats faster, and for smaller meals, it usually consumes less than turning on a large built-in oven; the actual cost depends on usage time.
Does it need special installation?
No. It works with a standard 230 V household outlet. You just need to place it on a stable, heat-resistant surface with free space around it for ventilation.
