Budgeting this room honestly

Start from the tier that matches the room's job — traffic and moisture, not looks, should pick it. In a 360 sq ft room every $1/sf of material tier is a ~$396 decision, while installation labor stays fairly fixed at about $3,600 nationally (states run 0.80x–1.25x). The 10% waste factor is already baked into everything on this page.

Example mid-range build: Large-Format Porcelain (24×24 or 24×48 · Premium porcelain · Rectified edge) — material $3,164, labor $3,600, total $6,764 for the full 18x20 room.
