Frequently Asked Questions
How many boxes of vinyl flooring do I need?
Divide your adjusted square footage (room area plus closets, times waste factor) by the box coverage. For a 12x15 room (180 sq ft) with 10% waste and 23 sq ft per box: 198 sq ft / 23 = 8.6 -- round up to 9 boxes.
How much waste should I add for vinyl plank flooring?
For a straight lay in a simple rectangular room, 10% is standard. For diagonal installation or rooms with many angles and obstacles, add 15%. Always add at least 5% even for simple installs.
Does vinyl flooring need underlayment?
Many luxury vinyl plank (LVP) products come with a pre-attached underlayment pad. If it does not include padding, a separate underlayment improves sound absorption and surface leveling. Check the box before buying separate underlayment.
Should I include closets in the estimate?
Yes -- closets are part of your installed floor area. The extra area field lets you add any closet or irregular space beyond the main room dimensions.
How much leftover flooring should I keep?
Keep at least 10% of your total purchase as spares. Vinyl plank can be damaged later and exact matches from the same production run may not be available in future years.
Can I install vinyl flooring over tile?
Often yes -- vinyl plank can be installed over existing tile if the tile is flat, firmly bonded, and grout joints are not too deep. Deep or wide grout lines may telegraph through thin vinyl. Check the product specifications.
What is the difference between vinyl plank and laminate?
Both float over the subfloor, but vinyl plank is 100% waterproof and better for kitchens, bathrooms, and basements. Laminate has a wood composite core that can swell if water gets underneath. For wet areas, vinyl plank is the safer choice.
