Couple of boxes should be sufficient.

There’s no point in keeping more than a couple of boxes for incidental repairs. Any flood event will mean 100% replacement, so be sure your insurance is structured for actual replacement costs. Not prorated as to current used value.

How much flooring would you need to do the whole condo ? That is how much flooring you need

When I install floors, I always order 5%-10% more just in case.

When I sold cork floating flooring that was discontinued, I ALWAYS suggested having somewhere around 100sf of extra (5 boxes) on hand should something CATASTROPHIC happen. That is a SIGNIFICANT amount of replacement product. You could lose the ENTIRE kitchen without having an issue. You could repair a FULL bedroom (small second bedroom...but still) without having to worry about having to change the entire floor.

You will want the 5% extra for the INSTALLATION waste...you will need another 5% extra to have that 60-80sf of 'extra' floor left over (4-5 boxes). But the issue: CONDOS do NOT have storage. Certainly not the type of storage that allows these boxes to lay FLAT. These cannot lean up against a wall in a closet. The bending of the planks would ruin any chance of installing the material at a later date.

i would recommend to replace the entire floors for the sake of just looking niuce and clean

"i would recommend to replace the entire floors for the sake of just looking niuce and clean"

What??????????

I would assume two boxes for a 600 square foot condo would be adequate. If a higher percentage of your flooring needed to be replaced, it would probably make more sense to replace everything. Two boxes represent a greater percentage of floors in a small condo versus a place with 2000 square feet of flooring.

I have always assumed you keep extras around for relatively small damaged areas.

I have limited storage but stashed the boxes laying flat on a top shelf of a closet. The advantage is also they are in a climate controlled environment.

I'm in the 2-5 boards group myself. rugs are always an option! :)

Sorry reread and it seems you are doing the whole condo so I would think 2 boxes should be good.

Thank you all for your replies.

A little clarification. The floors are already installed. I'm just concerned with having to replace some. Say if the floors in the 168 sqft bedroom (recently installed) start to buckle or I spill a huge pot of hot soup in the dining room and it messes up the floors. Also, I called around and got the price down to $1.29 sqft.

@live_wire_oak- I made sure to get replacement value coverage.

@SJ McCarthy-Good point about the storage. I was planning to lean them against the wall in my hall closet. I didn't think about needing them to be flat. I have a small walking closet that I could stack them in. I also have an outdoor storage closet with plenty of room but it's not climate controlled.

If they aren’t from the same dye/stain lot, I wonder if the color will match. Do you have any spare pieces from your original installation that you can take to the store to compare?

always assume your selections will be discontinued.

This is a realistic choice. Obviously, it won't help you at all if your whole place floods, but it's quite possible that you'll drop a knife /gouge a bad spot in the floor ... or your child will draw on the floor with a Sharpie ... or a pet will damage a small spot.

How much? I vote for 2-3 boxes.

A bit of this depends on the quality of the flooring. Better flooring will need less replacement. In any case, I don't think the type of damage you mention would exceed a 4' x 4' area, or 16 square feet.
