I'm looking for ideas on replacing the current hearth extension for our insert. Right now it's the fake stone which is very uncomfortable to kneel on:
Plus, it's crumbling apart:
It's 25" from the front of the insert and 60" wide. It's laid on some kind of fake wood subfloor:
Our idea is to pull all the rock and mortar up, lay down some kind of cement board and tile. But cutting tile to match the curves could be tricky. The other idea is to just mix up a bag of Quikcrete and dump it in. (It's an inch deep.)
If we go the Quikcrete route do we need a special kind of concrete? And could/should we pour it over the subfloor or should there be some kind of heat barrier also?
Thanks for any and all suggestions/help/guidance.

Update: Just found the manual and it says "a non-combustible hearth extension equivalent to 3/8" millboard (R=.75, C=1.3, K=0.5) must be used. If the unit is to be installed without a raised hearth, it must extend 24" in front of and 8" beyond the sides of the fuel opening."
