Wholesale factory prices for white porcelain tile vary widely, from under $1 per square foot for bulk, direct-from-China imports (like on Alibaba or Made-in-China.com for large minimums) to $5-$10+ for domestic options, depending on quality, finish (matte, polished), size, and quantity; expect to pay significantly less per square foot buying in bulk directly from manufacturers or wholesalers than from big-box retailers who add markups.
