You can look at this two ways, 1. You can make a custom pit to your exact specs or 2. Buy one that is close enough. That is the difference in the cost. Answer from Grymflyk on reddit.com

r/DIY on Reddit: Interested in making a DIY gas firepit. It seems more costly to try to do it myself than buy one. Am I missing something?
July 10, 2024 -

So as the title states I'm doing research for a natural gas fire pit. I have a gas line for my pool heater near where I want to build the fire pit so I planned on extending this for the fire pit (my BIL is a plumber so he would help with gas piping). After looking into it, it seems way more expensive to build my own with landscape blocks, purchase a burner table, burner controls, burner than to just by one already assembled. Am I going about this wrong?

See links I am referencing:

52 landscape blocks for a 36" firepit

38" burner table

30" burner

I’m well over a thousand dollars and this isn’t even including the rocks to fill the pan, material for gas pipe, etc. Anyone have experience with this?

Natural Gas is lighter than air and will rise to the top of the fire pit. Install the air vents on opposite sides of the fire pit toward top of the base. The enclosure is the body of your fire pit.

How much fire glass or lava rock do I need in my DIY fire pit? For fire glass, we recommend roughly 90 pounds per square foot of the enclosure area. For lava rock, we recommend 45 pounds per square foot as the pieces are larger and there will be more empty space in between them. How much heat does a fire pit kit generate? This will depend on your burner size and fuel supply. Generally, 50,000 BTUs is a safe bet for smaller units while a large natural gas fire pit kit can put out as much as 300,000 BTUs provided it receives enough fuel.

This not only establishes a secure buffer between the heat and your fire pit’s edge but also contributes to an aesthetically pleasing appearance. Early in your project, choose your fuel type and incorporate proper ventilation. Given that propane gas is heavier than air, install vents as low as possible to facilitate the escape of any unburned gas. Conversely, natural gas, being lighter than air, requires vents positioned higher on your build to allow for the rise of gas.

Quick Tips for Installing a DIY Natural Gas Fire Pit
July 26, 2024 - Keep in mind that natural gas is lighter than air, so when planning the location of your ventilation points, they should be placed in the uppermost portion of the enclosure. This allows the gas to rise and dissipate. There are two types of fittings used for gas fire features. These two types cannot be connected to each other without a “coupling” to convert the fitting types. One type of fitting used in many commercially made fire pits and barbecue grills is the flared fitting.

March 18, 2020 - Some of our manufacturers have different regulations for burner size, but a good rule of thumb is to have three inches between the edge of the burner and the inside edge of your pan on all sides, so a difference of six inches between burner size and inside fire pit dimensions. For both propane and natural gas, 36 square inches of ventilation is required to create proper air flow within your fire pit.
