Budgeting this room honestly
Start from the tier that matches the room's job — traffic and moisture, not looks, should pick it. In a 396 sq ft room every $1/sf of material tier is a ~$436 decision, while installation labor stays fairly fixed at about $693 nationally (states run 0.80x–1.25x). The 10% waste factor is already baked into everything on this page.
