Keep your Karu 16 if wood or charcoal cooking already suits you; consider the Karu 2 Pro for its glass door, digital temperature display, and app features. The Ooni Karu 2 Pro vs Karu 16 choice is an upgrade decision, so focus on what changes in your cooking routine.
The Karu 2 Pro works with wood or charcoal out of the box. Gas is an option with a separate Karu 2 Pro burner, while the Karu 16's features aren't detailed here for a full model-by-model spec comparison.
What changes with the Karu 2 Pro?
The Karu 2 Pro adds a glass door, a mounted digital thermometer, and Ooni Connect app functionality. Those features may help if you want to watch the pizza without opening the oven and check its internal temperature.
The Karu 2 Pro has an insulated oven body and reaches 950°F, with Ooni stating it can reach that temperature in 15 minutes. Its glass door is designed to retain heat while giving you a view of the cooking area.
These are specific reasons to consider changing ovens, but they don't make the Karu 16 a poor choice. If its fuel and cooking workflow work for you, a new door or display may not change your results enough to justify replacing it.
For a closer look at those features and the oven's fit, read our Ooni Karu 2 Pro review and check the Ooni Karu 2 Pro dimensions before planning a spot for it.
Which fuel setup fits your cooking?
Keep the Karu 16 if you want to stay with the fuel routine you already know; choose the Karu 2 Pro if wood, charcoal, or an optional gas setup fits your plans. Its gas burner is a separate attachment and only works with the Karu 2 Pro.
The Karu 2 Pro uses wood or charcoal out of the box. The gas burner attaches to the back, includes a regulator and hose, and has a heat control dial with a low-power cooking function.
That flexibility is useful if you want to switch between solid fuel and propane. It also means an extra component to buy and store, so skip the burner if you expect to cook only with wood or charcoal.
This burner cannot convert a Karu 16 to gas. Confirm the exact model compatibility before choosing any attachment, especially if propane is the main reason you're considering an upgrade.
Does the Karu 2 Pro cook faster?
The Karu 2 Pro is specified to reach 950°F in 15 minutes and cook pizza in 60 seconds, but there isn't a comparable Karu 16 figure here. Those numbers alone don't show that upgrading will make your own cooking faster.
Preheating and baking time depend on conditions and how you manage the oven. If your Karu 16 already reaches the heat you need on your schedule, a speed claim for the newer model may not be a practical reason to replace it.
Focus on the change you can identify: easier viewing, temperature information, app functionality, or a different fuel option. If none of those addresses a regular frustration, keep using the oven you have.
Is the Karu 2 Pro a better fit than a gas oven?
The Karu 2 Pro suits you if you want wood or charcoal with the option to add gas; a gas-only oven fits better if you want a propane setup as its standard fuel. Those are different ways to solve the convenience question.
The Ooni Koda 2 Pro Gas Pizza Oven is a separate propane-only option, and the comparison explains how the Karu and Koda approaches differ. The Koda 2 Pro includes a propane hose and regulator, while the Karu 2 Pro burner is an extra attachment.

What should you check before replacing a Karu 16?
Check the cooking area, exterior dimensions, fuel setup, and the features you would use often. A newer model is an upgrade only when its differences solve a real need.
The Karu 2 Pro is described as having a 17-inch-wide cooking area, but that figure alone doesn't tell you how it compares with the usable space in your Karu 16. Check both ovens' manuals and measurements if your typical pizza size or cooking surface is the deciding factor.
Measure the place where you cook and store the oven, including the space needed around it. Also consider whether you'd use the glass door, thermometer, app functions, or gas attachment often enough to make those features worthwhile.

Is the Karu 2 Pro worth upgrading to?
Upgrade to the Karu 2 Pro for features you'll use regularly; keep the Karu 16 if its fuel setup and cooking workflow already meet your needs. The strongest case for changing is a specific improvement, such as a glass door, temperature display, app functions, or the option to add compatible gas power.
Choose the Karu 2 Pro if those features address a gap in how you cook. Keep the Karu 16 if you're satisfied with it and don't need the newer controls or viewing features.
Frequently asked questions
Is the Ooni Karu 2 Pro bigger than the Karu 16?
The Karu 2 Pro is described as having a 17-inch-wide cooking area, but the information here doesn't guarantee a like-for-like interior measurement against the Karu 16. Compare the usable cooking area and overall dimensions in the manuals before deciding whether the newer oven changes the space you have.
Can I use the Karu 2 Pro gas burner on a Karu 16?
No. The Karu 2 Pro Gas Burner is compatible with the Karu 2 Pro only, so it isn't an upgrade attachment for the Karu 16.
If adding gas is your main reason to change ovens, check current Ooni compatibility details for the exact Karu 16 model before choosing another burner.
Does the Karu 2 Pro include a gas burner?
No. The Karu 2 Pro uses wood or charcoal out of the box, and its gas burner is sold separately.
Add the burner only if you want the propane option, and check that the included regulator and hose suit your local setup.
Should I replace a working Karu 16 with the Karu 2 Pro?
Replace it when the Karu 2 Pro's specific features solve a problem you have, such as wanting a glass door, a mounted digital thermometer, app functionality, or a compatible gas attachment. If you mainly cook with wood or charcoal and your Karu 16 meets your needs, keeping it may be the simpler choice.
Is the Karu 2 Pro gas burner worth buying?
It may suit you if you own a Karu 2 Pro and want propane cooking with a heat control dial and low-power function. It doesn't work with the Karu 16, and it is a separate purchase, so weigh that compatibility and added cost against how often you'd use gas.
