Choosing between the Cub and the Grizzly is mostly a question of space, weather, and how often you expect to run the stove. The Cub is the smaller option for compact rooms and shoulder-season heat. The Grizzly gives you more firebox and more output for a larger cabin or a colder climate. You can read the installation cost guide before you decide, because the flue and mounting parts matter almost as much as the stove itself.
The short answer
For a well-insulated space under about 200 square feet, start by looking at the Cub. For a space closer to 200 to 400 square feet, or a room that loses heat quickly, the Grizzly is usually the better fit. The official product information gives the Cub a lower output range and the Grizzly a higher one, but insulation, ceiling height, climate, and the actual layout can change the result.

When the Cub makes more sense
The Cub works well when you have a genuinely small space and do not want a large stove dominating the room. It is a sensible direction for a small boat cabin, a compact camper, a tiny house on wheels, or a cabin used mainly in spring and autumn. A smaller firebox can also make it easier to avoid overheating a small room, although you still need to learn how the controls respond in your installation.
Our boat and tiny-home guide looks at those use cases in more detail. It is worth reading if your space has unusual ventilation, limited floor area, or a mobile structure.

When the Grizzly makes more sense
The Grizzly is the stronger candidate when the room is larger, the winters are colder, or the building envelope is not especially tight. It gives you more room to work with, but that does not mean it should be placed in a tiny room simply because it can produce more heat. Oversizing can make a small room uncomfortable and encourage short, hot burns.

Compare the Cubic Mini Grizzly options before choosing between certified and non-certified versions. Confirm the current documentation for the exact model you are considering.
Installation can change the decision
The stove is only one part of the project. You also need to plan the flue route, roof or wall exit, floor protection, shielding, and the mounting method. A model that fits on paper may not fit safely once clearances and the chimney route are measured.
Check the Cubic Mini clearance guide and review the available mounting and flue options before ordering.
Final recommendation
Choose the Cub when your space is genuinely compact and your main need is efficient heat during cooler parts of the year. Choose the Grizzly when you have more volume to heat and need additional output. Do not choose only by the advertised square-foot figure. Measure the room, consider insulation and climate, then confirm the installation with a qualified professional and your local rules.
