What it is

A small, Canadian-made, wall- mountable, DIY-friendly wood stove for small spaces (bunkies, cabins, RVs, larger boats, etc.).

The test

The Grizzly is Cubic Mini’s larger (but still tiny) wood stove, rated for between 8,000 and 18,000 BTUs.

I ordered everything (stove, flue pipes, heat shields and roof exit kit) online and had it at my door in just over a week. The materials are very well made. It’s a solid stove with high-quality stainless steel flue pipes.

I installed it at my cottage to warm a 320-square-foot space. Installation was straight forward. I had it all up within about five hours (including cutting the hole through my roof).

I first fired it up in late September. The factory coating takes a while to cure and releases a horrible chemical smell and some smoke as it does. The instructions do say to fire it up outdoors before installing, but it was in small text and I missed it. Definitely burn it outdoors for at least 24 hours before you install.

Throughout the fall, heat output was fine. The space (7-foot ceiling, 1980s mid-range insulation, and lots of large windows) warmed up from a chilly 60°F to a comfortable 69-ish in about an hour.

In the winter, at -10°C temps, the stove really struggled to warm up that much space. I ran it for 5-6 hours several times while I popped up to the cottage to ice fish, with barely a perceptible rise in temperature. With time, I think it could warm the place up but it just can’t get the job done in a relative short time.


Awesome for spring and fall in the right space. I’d say this stove would shine for RV users, van-lifers, or if you have an off- the-grid cabin that’s a couple hundred square feet and has modern insulation. Although tiny, itʼs really well built.
