Welcome, Avery.

Don't know what sort of material that might be on your floor, but over a wood framed subfloor there is no ceramic tile industry method of installing only one inch of mortar without a cleavage membrane and expanded metal mesh.

You're certainly free to tile over whatever you want, though.

My opinion; worth price charged.
