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?

Built a pretty sweet DIY backyard fire pit that's done really well at helping keep the smoke down and not blowing in people's faces. There's different ways you can get the right air-flow to get a *smokeless* effect. This is how I did it - hopefully some helpful tips/inspiration.

Here I’m replacing our old worn out fire pit with a new modern concrete one. We picked up the fire pit as a kit from a local concrete centre here in Southern Ontario. The kind of place that makes custom concrete pieces for the yard - think bird baths, statues, fireplaces etc.

They had different options like the round one we got as well as square and rectangle. It comes with the white bricks and the metal insert. The only other material we used was a layer of bricks at the bottom from the old fireplace. These were just basic garden edging bricks and you could substitute with another kind you might have around.

The cool thing is if you build these things right you can greatly eliminate smoke which makes it so much more enjoyable to sit around and the neighbours appreciate it too :) I talk about how this works near the end of the video.
