I've seen gravel used around fire pits quite a bit, and honestly, heat retention hasn't been a huge issue in my experience. Sure, it gets warm, but not enough to make cleanup noticeably harder. Just let things cool down overnight, and by morning it's usually fine to handle. But your point about drainage is spot-on...gravel definitely helps avoid puddles after rain, which is a big plus. Sounds like you're thinking this through pretty well!
"Just let things cool down overnight, and by morning it's usually fine to handle."
Totally agree with this. When we built our fire pit last summer, I was a bit paranoid about safety too (first-time homeowner nerves, lol). Here's what worked for us: after the fire dies down, spread out the embers a bit with a poker or shovel—helps them cool faster. Gravel's been great for drainage, but we also added a metal ring liner inside the pit itself...just an extra layer of peace-of-mind. Haven't had any issues yet, fingers crossed!
I get the logic behind letting it cool overnight, but honestly, embers can stay hot way longer than you'd think. Last fall, I checked ours the next morning and figured it was safe, but when I stirred the ashes around, there were still glowing bits underneath. Gravel's good for drainage, sure, but I'd personally feel safer with sand or fire bricks at the bottom—just seems more heat-resistant than gravel.

Definitely helps, but I'd still double-check carefully before assuming it's totally cooled off. Better safe than sorry...
- Totally agree about sand or fire bricks being safer than gravel—heat resistance matters.
- Also, have you considered a metal lid or mesh cover overnight? Keeps sparks contained and feels way more secure.
- I've seen embers still glowing after 12+ hours... pretty surprising.
Definitely agree on sand and fire bricks—gravel can sometimes trap moisture, which expands under heat and can cause popping or cracking. Not ideal. A metal mesh cover is a smart suggestion too; sparks can travel surprisingly far, especially if there's a bit of wind.
One thing I'd add: consider the pit's proximity to surrounding structures or vegetation. Even with safety measures like lids or bricks, radiant heat can still ignite dry leaves or wooden decking nearby. I've seen cases where people underestimate how hot surfaces around fire pits can get, leading to unintended damage or even fires.
Also, if embers are glowing after 12 hours, that's a good reminder to always double-check before leaving the area unattended overnight. A quick stir and dousing with water or sand can help ensure everything's fully extinguished. Better safe than sorry...
