Enough grill space to cook for a whole party
Industry-leading lifetime warranty
Side shelves to expand your preparation and storage space


Prohibitive startup cost

2. Runner Up - MHP WNK4DD Natural Gas Grill



  • 40,000 BTU max power output
  • 433 1/2 square inches of cooking area
  • Equipped with two folding stainless steel side shelves
  • 48 inch anodized aluminum in-ground post
  • H-style stainless steel burners
  • Cast aluminum exterior housing
  • Uses natural gas or propane
  • Lifetime warranty

Impressed by our top pick, but not willing to shell out that much cash for your grill? We understand. And if you’re willing to give up one of the Tri-Burns three burners, you can have all of the same awesome features in a smaller, more budget-friendly package with the MHP WNK4DD.

Two stainless steel burners are arranged in an efficient “H” shape, providing an even distribution of an impressive 40,000 BTUs. Spread out over more than 400 inches of grilling space, this is plenty of power to be in command of your entire grilling station during backyard parties. Like its larger cousin, the MHP WNK4DD also comes with a lifetime warranty.

Overall, it’s a fantastic alternative to our #1 pick for anyone working with a smaller budget.


Efficient and effective “H” style burner design
Excellent heat output is more than enough to sear steaks to perfection
Lifetime warranty protects your investment forever
Compatibility with natural gas or propane makes it suitable to any patio
Amazing price for how rugged and durable it is


Slightly less powerful than our top picks

3. Premium Choice - Fire Magic Choice C430S Natural Gas Grill

Fire Magic Choice C430S


  • 46,000 BTU max power output
  • 432 square inch cooking area
  • Constructed of 304 gauge stainless steel
  • Equipped with two 16-gauge U-shaped stainless steel burners
  • Mounted on an in-ground post
  • Includes warming rack and drip tray
  • 3-15 year warranty, depending on part

When nothing but the best will do for your backyard grilling setup, you have to turn towards more expensive grills to satisfy your desires for the ultimate in grilling power. But it can be challenging to determine which pricey grills are truly substantial, and which are just flashy…

The Fire Magic Choice C430S definitely falls in the “truly substantial” category. From the first look at its exceptionally heavy duty 304 stainless steel construction, you can tell that this grill means business. Two U-shaped stainless steel burners back this up, providing an amazing 46,000 BTUs of heat to over 400 square inches of cooking space.

What really sets this grill apart from the rest, though, is even heat distribution. The combination of heavy gauge steel and innovative burner design simply gives more heat, more directly to every part of the grill. To extend its capabilities a smoker box can be added for people who want to use it to smoke meats. Of all the post mount grills we reviewed, the Fire Magic Choice C430S delivered the most consistent results for grilling steaks, chops, and everything else we wanted.


Best heat distribution of any grill we reviewed
Thick, heavy stainless steel construction is made to last
Huge grilling space accommodates over two dozen burgers
High maximum power output means perfect grill marks every time


Too expensive for some buyers

4. Great Versatility - American Outdoor Grill T-Series Natural Gas Grill

AOG T-Series 24NGT-00SP


  • 32,000 BTU max power output
  • 432 square inch grilling space
  • Made of 304 grade stainless steel
  • Equipped with two stainless steel burners
  • Mounted on an in-ground post
  • Lifetime warranty on burners; 10 years on everything else

Occupying an excellent space right in between the versatility of our #1 pick and the even heating of our Premium Choice grill, the American Outdoor T-series grill manages to provide excellent performance at a reasonable cost.

Two stainless steel burners provide a somewhat less than great 32,000 BTUs of heat across 430 square inches of cooking space. If it weren’t for the thick, heavy duty 304 grade stainless steel that the unit is made of, this lack of heating power might hold it back; as it is, though, the dense metal leads to perfectly even heating for easily controllable grilling.

While it may not offer the raw power of the previous three grills, its combination of rugged construction and even heating at an excellent price make it a choice worth considering.


Heavy duty 304 steel is made to last
Extremely even heating makes for predictably great grilling
Plenty of cooking space to feed an entire summertime party


Somewhat underpowered

5. Biggest Grilling Space - Broilmaster P3-XFN Premium Natural Gas Grill

Broilmaster P3-XFN


  • 45,000 BTU power output
  • 695 square inches of grilling space
  • Two stainless steel burners
  • Adjustable, multi-level cooking grates
  • Adjustable lid stop for temperature control
  • Mounted on an in-ground post
  • Limited lifetime warranty on main grill components

If you’re looking for a grill that’s big enough to cook hot dogs, hamburgers, veggies, steaks, and chops side by side, you’ll be delighted by the Broilmaster P3-XFN. With a larger grilling space than any other post mount gas grill in our review, it’ll let you be the master of your backyard barbecue no matter how many people crash your party.

Nearly 700 square inches of grilling space are presided over by two stainless steel burners producing 45,000 BTUs of heat. With adjustable level cooking grates, you can decide just how close you need your meats to the fire — allowing for perfect grill marks on steaks and chops, or low, even heat for tender juicy chicken breasts.

All said and done, the Broilmaster P3-XFN is the most versatile and customizable post mount gas grill you can find. And at a reasonable price, it’s a fantastic option for anyone who loves grilling for a crowd.


Largest grilling space available for a post mount gas grill
Amazing adjustability and customization options
Easily accommodates a whole party’s worth of grilling
Limited lifetime warranty protects your investment from damages


Huge grilling space uses up a lot of fuel

6. Easiest Installation - PGS T-Series T40 Gas Grill

PGS T-Series T40


  • 40,000 BTU from two burners
  • 434 square inch cooking area
  • Stainless steel H-shaped burner
  • Electric ignition system
  • Gas flow timer with 1-hour no-use shutoff
  • Two stainless steel side shelves
  • Mounts on a 48-inch bolt-in patio post
  • 1-year parts replacement warranty

So far, every grill in our review has been one that requires in-ground installation. While this is the most stable and durable option for post mounting, it’s also not the most convenient. For that, you’ll have to look towards the bolt-in mounting of the PGS T-40 gas grill — an excellent option for anyone whose yard can’t accommodate in-ground installation.

Originally designed for use in apartment complexes, condos, and other shared-use spaces, the PGS T-40 is a rugged and durable grill with plenty of power and grilling space. With the use of some common power tools and cement pilot screws, you can install it directly onto any patio. 

Equipped with an automatic shut-off valve, you won’t have to worry about wasting gas if you forget to turn it off. Overall, it’s a great choice for anyone who wants to mount their grill directly into a concrete patio.


Easier installation than in-ground post mount grills
Great power and grilling space
Extremely durable construction
Automatic safety shutoff


Could be more powerful for the price

7. Best Combo Grill - Broilmaster R3BN Infrared Combination Gas Grill

Broilmaster R3BN


  • 40,000 BTU cooking power
  • 695 square inch total cooking area
  • Two burner styles: Infrared and conventional
  • Burners can be operated independently
  • Adjustable lid stop
  • Mounts on a steel in-ground post
  • Limited lifetime warranty on select components

Infrared grills are a relative newcomer to the outdoor grilling scene. By directly heating the grill grates, they provide a more even and consistent temperature across the whole cooking surface — but lose some of the char-grilled flavor people love. Wouldn’t it be great to have the best of both infrared and traditional worlds?

That’s what we want, too — which is why the Broilmaster R3BN caught our attention. Its 40,000 BTUs of heating power are split between one traditional gas burner, and one infrared. The result? Even, consistent grilling without any loss of flavor.

It’s a bit more expensive than many grills on our list, but we think it well worth the price given how reliable its grilling results are. If you’re a fan of infrared or just love the idea of trying out the latest grilling technology, give it a shot!


Combines the best of traditional and infrared burner styles
Perfectly even and consistent grilling performance
Excellent flame-broiled flavor


Somewhat underpowered for the cost

Final Verdict

MHP Tri-Burn W3G4DD

As the only option available with three burners, the MHP Tri-Burn W3G4DD Natural Gas Grill ran away with the show here. It has incredible heat production from its three durable burners, and plenty of space to cook for a whole crew. With tons of features at a reasonable price, it’s easily our #1 pick.

If you’re looking for a more budget-friendly option, consider the MHP WNK4DD Natural Gas Grill. As the “little brother” to our #1 pick, it loses one burner — but no grilling space. At a fraction of the price of our top pick, it’s an excellent option to save some cash.

Thanks for taking the time to read our guide to the best post mount gas grills. We hope our in-depth reviews have been helpful in pointing you towards the perfect grill for your needs!

How to Choose the Best Post Mount Gas Grills?

When you’re deciding on a post mount gas grill, take these 4 features into account to determine which is best for you:


How much heat your grill can put out will determine not just how fast you can cook your food, but how well seared it turns out. If you’re interested in cooking the best steaks possible, the higher the power the better!

Heating power for grills is measured in British Thermal Units, or BTUs. They’re a handy measure of how much heat energy a source produces, and are defined as the amount of energy necessary to raise 1 pound of water by 1 degree Fahrenheit.

Whereas a standard 2-burner gas grill might produce 24,000 BTUs of heat, post mounted grills can easily range upwards of 40,000 BTUs. This extra power makes them a superior option for professional quality grilling.


Making the commitment to install a grill in the ground also means that it will be outside, in the elements. If your grill’s construction isn’t up to the task, it’ll end up as a poor investment over time.

We look for stainless steel construction in all of our post mounted grills. This prevents rust and damage over time in a way that other metals can’t. Also, consider purchasing a grill cover to go along with your newly installed grill.

Grilling Space

Just how much room does your grill give you? If you plan on cooking for a large family or a backyard party, any extra space will pay off in the long run. Post mounted gas grills have the edge over portable grills in this regard, as they don’t need to worry about stabilization.

Ease of Use

Any grill is only as good as what you intend to use it for — and this is never more true than with a post mounted gas grill. Because you can’t roll them around to a new spot in your yard whenever you’d like, you’ll need to plan for using and cleaning them in the same space.

Ease of use comes down to a combination of simple cleanup and helpful extras. We look for grills that have a built-in grease tray and grates that are designed for extended use, as both of these help make cleanup a breeze. Integrated tool storage is a huge help not only while grilling, but once it’s time to finish up for the night too.
