Raise stove

I hope to see a good answer here, I'm about to do the same.

Masonry's an option, perhaps...depends to a certain extent what's under the stove now, but maybe not so much. One of my installations is masonry on slab, the other's masonry on wood subfloor. Rick

Whatever you decide to do, you have to pay attention to the manufacturer's stated requirements for the insulative properties of the hearth. If it's as simple as "ember protection only", then that's pretty easy...if it has a required r-value, then more thought has to go into the materials and construction. Clearance to combustibles is a three-dimensional concern, so beneath the stove is every bit as important as to the sides & rear. Rick

I wanted to do the same thing -raise a stove on a concrete slab (in a breezeway). I did it with several solid concrete blocks - I believe the dimension of the blocks is 4 x 8 x 16. The blocks are standing on the 8 inch side. On top of the blocks is a hearth pad from American Hearth pads. ( I think).
The hearth pad was VERY heavy. It is made up on cement board with a metal edge. For added strength I placed a section of 3/4 plywood under the hearthpad on top of the blocks. The plywood sheet is completely hidden . This raised the stove up by almost 10 inches. I will take some pics and post them. It worked out very well -you don't have to kneel down to add wood and you can see the fire better. I am sure a full masonary project would have been better but this cost way less and works very well The sheer weight of the hearth pad ensures that the blocks are not going to budge.

Everything that you see is solid brick, but the bulk of the hearth in each case is made up of typical concrete block laid in mortar to quickly establish the bulk of the hearth, then the brick "facade" is applied in mortar around and on top of the blocks...if my description makes any sense. It would be referred to as a "solid masonry" structure, although there certainly are air pockets down inside there, as it's not just one brick stacked upon another, but nothing combustible was used in either one.
