Budgeting this room honestly

Start from the tier that matches the room's job — traffic and moisture, not looks, should pick it. In a 300 sq ft room every $1/sf of material tier is a ~$330 decision, while installation labor stays fairly fixed at about $525 nationally (states run 0.80x–1.25x). The 10% waste factor is already baked into everything on this page.

Carpet note: figures include a standard rebond pad ($0.60/sf). Upgrading to memory-foam pad adds roughly $150–$300 but extends carpet life.
Example mid-range build: Nylon Cut-Pile Carpet (Nylon fiber · Cut pile · 35–45 oz face weight) — material $1,317, labor $705, total $2,022 for the full 15x20 room.
