John B.★★★☆☆November 27, 2013
Good grill, but a few quirks

The SUN4B-IR is a solid grill, and the infrared burners get super hot for searing. Installation was straightforward for a built-in, but I wish the igniters felt a little more robust. Overall, it's a good addition to my outdoor kitchen, just not quite perfect.

Jessica F.★★★★☆September 7, 2019
Great searing power!

I'm really impressed with the infrared burners on this Sunstone grill. It gets to temperature fast and gives a fantastic sear on steaks and burgers. The 34-inch size is perfect for my family, and it looks sharp built into the counter.

Kimberly T.★★★★★April 30, 2023
My backyard just got an upgrade!

This Sunstone 4-burner infrared grill is an absolute beast! The natural gas hookup was simple, and the cooking performance is incredible – everything comes out perfectly. It's truly the centerpiece of my new outdoor kitchen, worth every penny.

Sharon I.★★★★☆October 5, 2022
Solid performance for the price

As a contractor, I've installed a lot of outdoor grills, and the SUN4B-IR is a really good option for the price point. The build quality feels substantial, and my clients are always happy with the cooking results. It fits well into standard outdoor kitchen designs.

James R.★★★★★July 29, 2017
Best built-in grill I've owned!

Wow, this Sunstone grill is fantastic! The infrared burners are a game-changer for searing, and the even heat distribution across all four burners is excellent. It was a breeze to install as a natural gas unit, and it looks incredibly sleek in my outdoor kitchen setup.

Q
I love the idea of the infrared burner for searing, but how do I keep the grates and the infrared burner clean after cooking greasy burgers or steaks?Asked by Sunstone Support Team
A
Cleaning the Sunstone® 4-Burner 34-Inch Built-In Infrared Gas Grill, especially the infrared burner, is crucial for performance. For the cooking grates, burn off any residue on high heat for 10-15 minutes, then brush with a stiff brass brush. For the infrared burner, after it cools, gently brush off any food particles; avoid using harsh chemicals or abrasive brushes directly on the ceramic element to prevent damage and maintain its searing capability.
