How do you choose the right floor?
It depends on use and room: laminate and vinyl for tight budgets and fast installs; hardwood for warmth and longevity; carpet in bedrooms; epoxy in garages and shops. Traffic, moisture and radiant heat shape the choice.
The calculators give boxes, underlayment, baseboard and cost per area so you can compare options with real numbers.
What subfloor prep is needed?
New flooring needs a flat, dry, solid base. Dips over about ⅛ in in 6 ft get self-leveler; slab moisture is tested before wood or resin, and a vapor barrier goes over concrete.
Skipping prep is the top cause of squeaks, gaps and lifting.
How much waste for flooring?
5–10% for straight lays, 15% diagonal, 20% herringbone. Small or cut-heavy rooms need a couple more points, plus spare boxes from the same lot.
Baseboard and transitions are figured separately by linear foot.
