Identify Why the Threshold Is Raised
A decorative transition strip, flooring-height change and exterior-style sill are different conditions. Some thresholds cover expansion gaps or protect material edges and cannot simply be removed without replacing their function.
Flooring on Both Sides
Hardwood, tile, carpet and resilient flooring need different transition details. Lowering the profile may require undercutting, a tapered reducer or changes to one flooring edge. The goal is a stable finished transition, not a loose improvised strip.
Door Clearance
Changing the threshold can alter the gap under a door. Verify the slab swing and weather/seal function for doorway locations before changing height.

For interior threshold lowering, safety & accessibility remains the separate route when that adjacent need becomes the main customer task.
