Dressing up the heater
should be no problem at all. Plenty of options out there, should be possible to find something that will fit with your decor.
Bricks/blocks/stone can be done attractively, hold heat and release it slowly to keep a room toasty for hours.
Wood can be used, but if the stove got too hot there could be problems. Wood gives you all kinds of versatility-frame for tinwork, steps, mitten and
boot dryers, seating and carving just for starters.
Tile may offer the solution-looks, ease of installation, easy to maintain, holds up with the heat.
In my
experience, repurposing old farmhouse furniture can give a piece new life and preserve the flow of the living space. Perhaps an old toolchest or jelly cabinet could be used along with the stove?
