Linoleum and vinyl floors are among the least costly at $3 to $5 per square foot, while ceramic pushes the price up to $8 to $13 per square foot, slate $9 to $17, and marble or travertine $12 to $21. Sealed and waterproofed wood floors are at the high end, with bamboo the cheapest, laminate a mid-price choice, and hardwood equaling stone flooring in cost.
