Masterson BBQ Grill Island kits come with these features

We know how important a functional, durable, and enviable outdoor grill island is. So, we make all our BBQ grill islands out of non-combustible materials for safety and longevity. While it will probably only take you a few hours to assemble a grill Island kit, you will want to enjoy it for years to come. So, we design our grill stations to be low maintenance yet high-performance.

Summerset 32

Stainless Steel Sizzler Grill

Summerset Sizzler grills are professional in every way. Thus, their full stainless construction and professional features will impress discerning grillers for years to come. However, for those who demand more features, you can upgrade to the PRO model for added convenience.

Natural Stone Countertops

Your BBQ grill island serves as your outdoor kitchen. Therefore, you need ample room for prep and service. Hence, our outdoor grill islands include almost 12 square feet of countertop space. This gives you plenty of room to serve directly from your grilling station.

Non-Combustible Masonry Construction

Just because it is an outdoor kitchen doesn’t mean you can’t burn the house down. Therefore, to ensure you are keeping the family safe, we make all of our BBQ grill islands out of solid masonry. We use solid concrete blocks and stone tops for safety and low maintenance. Rest assured, this grill island will last .

Easy to Build

Like all of our outdoor living kits, this grill island is designed to be assembled in a few hours using our unique building system. In addition, the pieces are relatively small, and the instructions are simple to follow. You simply stack and glue the pieces together. No cutting blocks. No mixing mortar. No mess.

Our kits are easy to build for beginners with no heavy lifting

We have a unique building system

Designed to make kits easily

These blocks were specially designed to make hardscape features. These are not repurposed retaining wall blocks. This produces easy-to-make kits that save time. The wedge shapes help increase bonding ability for a solid product that is built to last.

Random stone look

Our stones are produced with through-body colored concrete. Then they are tumbled to give them a naturally aged look. The three sizes of block are able to create seven different face sizes creating the randomly laid appearance of natural stones.

No mortar needed

There is no mess and mixing of mortar. Our kits are simply glued together. You squeeze special adhesive from a caulk gun. This makes construction and clean up a breeze.
