Our Masterson-G BBQ Grill Island comes complete with built-in components

Cornerstone’s Masterson-G Outdoor BBQ Grill Island is your top choice when choosing the top value in stone outdoor grilling stations. We start with our easy-to-assemble solid masonry stones for a base that is stylish and durable. These are the same blocks used to create all our kits so you know that your outdoor living features will match. Then we add thoughtful features like a spice and sauce shelf and a recessed area to hang your grilling tools. We leave out the expensive stainless-steel drawers. If you don’t have your grill island under roof, then those drawers will fill up with water and debris. We like to keep everything low maintenance and high performance. That is why we top your BBQ grill island with almost twelve square feet of countertop stones. This allows you ample room to prep and serve your meals.

Finally, we top your outdoor BBQ grill island off with a killer outdoor grill by Summerset. This baby is professional in every way. Full stainless construction throughout, high output burners, and a lifetime warranty ensure you will be thrilled with your purchase. Since BBQ grill islands are rarely under roof, we recommend upgrading to the Pro model. Not only do you get better, hotter burners and heat zones, but you also get interior lighting to help you grill when the sun goes down. The interior lighting shines down on the grill and helps when the almes create a backlight and your double-insulated hood blocks the porch light. You’ll be glad you ponied up the extra cash. Rotisseries and sear burners are a matter of preference. But be sure to order a custom grill cover. It will keep your grill looking new.

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

Built-in 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

Shipping is FREE in the Contiguous US*. Your order will be shipped as freight via an LTL carrier. Freight is not like standard carriers. Your order will be on pallets that weigh up to 2000 pounds each. A freight carrier will drop them CURBSIDE with a liftgate. Someone will need to be present to accept the shipment.

All shipments must be made on asphalt or concrete. We cannot deliver on gravel.

LTL carriers will deliver CURBSIDE only. The delivery drivers will have a pallet jack for you to move your order. Delivery drivers are not responsible for deliveries past the curb.

All orders are produced in the order they are received. Orders typically leave our yard in 7-10 working days. Once Your order ships, it can take an additional 5-10 working days to get to you.

You will be provided with updates on your order, as well as a tracking number once it ships. When your order lands at the final terminal, you will be contacted by dispatch to arrange a delivery time. Someone must be present for delivery.

Refunds will not be issued for order refusal due to the delivery method.

Sorry. LTL carriers will deliver CURBSIDE only. The delivery drivers will have a pallet jack for you to move your order. Delivery drivers are not responsible for deliveries past the curb.

All orders are produced in the order they are received. Orders typically leave our yard in 7-10 working days. Once Your order ships, it can take an additional 5-10 working days to get to you. 

You will be provided with updates on your order, as well as a tracking number once it ships. When your order lands at the final terminal, you will be contacted by dispatch to arrange a delivery time.  Someone must be present for delivery.

If you live on a gravel road, you have a few options. Many customers will arrange delivery to a locally owned business. From there, you can pick up your pallets individually or have them delivered by a local vendor with that capability.

You can also make your delivery to a friend’s house that meets the requirements. You will be responsible for getting your material to your site.

You can always arrange to pick up the delivery at the nearest shipping terminal. There will be a window you must pick up your pallets. After several days, freight yards usually charge storage fees.

Shipping is FREE in the Contiguous US*

*In rare instances, free shipping is not available. There are a few remote places in the contiguous US that cannot accept direct shipment (Non-Direct Shipments). These are remote locations that are not near any shipping terminals. These locations require an extra third-party shipper to reach their destination. Therefore, we reserve the right to refuse free shipping to these destinations. You can elect to pay the additional expense of the third-party shipment or arrange pick-up of your materials at the nearest terminal. You probably know if you live in one of these locations, but we will inform you if your address fits in this category. We will not charge you without your consent.

Kits do not come with a warranty. I don’t want to alarm you.  We don’t sell a finished product. We only sell the materials and plans to build your kit. Though easy to build, people can modify the kit and could potentially build it in any number of ways that we cannot warranty. The materials are guaranteed to be complete and free from defects. Moreover, they are high-quality materials.  Built properly and well-maintained, your kit will last for years.

Free shipping means shipping is included in the price. The cost of shipping freight is high. You may be able to return your order within 14 days of delivery. If you choose to do this, you will be responsible for paying for return shipping plus a 20% restocking fee.  You will often get back less than half of your purchase price.

We do not want anyone to lose money on a purchase. Please be certain of your decision before shipping tons of material nationwide. There are all kinds of information available on this site. Contact us if you still have questions or can’t find what you are looking for. We will answer any questions you have.

You can cancel your order before shipment for a full refund. Special orders may incur cancellation fees.

Refunds will not be issued for order refusal due to the delivery method.

We do not inflate prices so we can offer discounts- not even for Black Friday. 

Planning for and constructing a large hardscape feature such as a fireplace is no small decision. We want you to plan accordingly. You will not be penalized for ordering your materials when it fits your schedule.

The lowest price is always the one currently available. We do not want you to be upset that we run a discount or promotion after you purchase your kits. We would not cheat anyone that way.

Military Discounts:

Thank you for your service. We believe in freedom and equality for all. Therefore, we do not offer any special discounts for military, first-responders, police, or firefighters.
