Reading the table for a 18x20 space
Notice how the installed range widens as tiers climb: material choice, not labor, is what separates a $2,678 job from a $7,718 one on the same 360 sq ft floor plan. Labor for mid-range hardwood lands near $1,530 nationally, plus or minus your state's rate. All rows include the 10% cut-waste pros actually order.
