It won't explode, it doesn't retain moisture like river rock which does when exposed to heat. The ring is made up of 8 pieces crimped together. It does provide protection but I would of preferred a solid ring. I've stated before if it weren't for the fact we wanted something gray and availability we would not have spent the $500 for this fire pit (my personal opinion).
I wouldn’t say it’s required but it’s looks great with it and helps trap some of the smoke.
Good afternoon, 48 mini RumbleStone 48 trap RumbleStone 1 Stainless Steel fire pit insert
I ended up using small stones (like QP - crushed stone) instead of sand and it was around two to four inch base under the firepit. I bought 1 cubic yard of small stones for the firepit and the area around the firepit which includes chairs, etc. The entire area that I created for the firepit area was 14 ft x 16 ft. Hope that helps.
JT, do you have any pictures of what you've done? I am trying to get some answers to do the same thing. I already have a insert, I just want the correct brick sizes and count. Plus I want to make mine taller. Good luck

We do not have bowls however, most contractors will fill the base with sand to keep the direct heat off of the existing concrete. Thank you for your inquiry!
The inserts will help to protect the life of the block and recommended. However, we have had lots of people use without the insert and not had any issues. Thank you for your inquiry!
I just put this together without the insert and the inside diameter is 31", not 36"
