FWIW I used to repair heated floors. On one job, not that old, the tiles at the bottom of the stairs were worn. They were the simulated wood type and the "Grain" was worn off. Flooring is rated by usage, light residential to commercial. There are trade off between cost, style durability.
Its hard to understand why tile ranges from .69cents a sq ft to $20.00+ , but to a large extent you get what you pay for
