If your floor is more than 2 years old, then you are going to have massive issues finding 4-5 boxes. With repair/replacement of 900sf, you are not going to find anything in that amount. You could scour the internet for a year and only come up with 6-8 cartons. That will only 'finish' a small bedroom.

I know this is disappointing to hear. I'm very sorry this has happened. If your floor is OLDER than 2 years old, then I highly recommend finding another floor for full replacement.

If you have separate rooms in that floor, you can salvage enough product from those rooms to COMPLETE the 'main' room and then find something else for the now-floorless rooms. Or vice verse. You can replace the 'main room' in something else that is complimentary to the 'other rooms' while leaving the others in place.

Is this a continuous space or are there other rooms involved? Photos of the space if you have them please.

Thank you, its a continuous space and more than likely will need to start over!
