Available: floor gypsum and tiles
Thinking: laying tiles on the floor gypsum according to best practices
Where I want to lay gypsum/tiles, there is the original foundation that a previous stove stood on, but it is smaller than the area I now want to use, so I end up a bit on the wooden floor (about 20 cm). Unfortunately, the floor is not exactly level compared to the foundation, so the gypsum wobbles a few millimeters when you stand on the outer edge. If I now lay tiles on top, everything is likely to collapse, right?
I assume I can put something between the gypsum and the wooden floor to even out the surface so that it becomes stable. But I don't want to use plaster. Wouldn't that ruin the wood forever? And foam probably won't withstand the pressure. What do I do?

You can put something other than foam in between, right? But it sounds like it will build up quite a bit in height, and I wouldn’t think it looks very nice. Additionally, it's quite impractical with a corner where you'll constantly hit the edge. I would have (and have done here) removed the foundation and sawed off a piece of the wooden floor to then lay floor gypsum and finally tiles.
The planet is rounded, like a half-moon, and I'm planning to edge it with a nice wooden strip so there will be no problems. The problem is what to have between the wooden floor and the floor gypsum so that it doesn't flex and without damaging the wooden floor. It's a difference of a few millimeters, but I will still likely crack the joints when I stand on the edge. Maybe masonite will work, but how stable will it be?
MDF board is definitely hard enough. The thickness will be the difficult part; I believe it comes in a few different thicknesses under 12 mm.
Is the underlying wooden floor completely free of flex then?

But the gap is wedge-shaped from the gypsum edge to the foundation. I might be able to fit 5 mm masonite under the front edge, but in between up to the foundation, there will be an air gap. Maybe foam in between so there is something, better than air?
The floor is stable, and additionally, 90% of the gypsum/tiles rest on the foundation where the stove will stand, so the issue of deflection only exists at the edges and if someone stands on an edge, which will likely happen sooner or later. The stove weighs 185 kg.

But then I'll mess up the floor?
I can't push the masonite all the way against the drywall. That would distort it in the other direction. Or it might be marginal, and I can fill in the wedge that forms between the drywall and masonite, at the outer edge.

Are you scribbling on the masonite?
To me, it's a "shortcut" solution you're planning and not something a professional would have done. I still don't understand why you don't remove the old foundation and cut away the floor to get everything at the same level? Are you planning at any point in the future to remove your new hearth plan and reveal the old floor?
