What moves the number in a 18x24 room
The spread comes almost entirely from product tier: Standard Ceramic Tile and Marble Tile — Luxury are several dollars per square foot apart, which compounds to a four-figure gap in a 432 sq ft room. Labor is steadier — about $4,320 here at national rates, drifting 15–25% with your state. Every figure already carries the industry-standard 10% material waste allowance.
