Devs. Please. Make it 2x1 and no taller than the fireplace.

Look, sometimes you need to dig a little to make everything level. This is true in game, and in real life.
You can mitigate this a bit by having a raised foundation using stone or wooden frames, then raising where you want the hearth to be using the hoe.
