Hey there anniesez,
This is Mr. Jay with The Home Depot out in Chicago.
Do you happen to have any of the boxes from the tile that was laid in that room? The reason I ask is that you may be looking at an issue with tile ďcaliber.Ē Just like how dyelots vary in production, so do the actual measurements of the tile; and they donít always come out 12 x 12 as written on the box.
In order to ensure that you get the proper fit, the caliber number is usually written on the box somewhere. Bring that with or note it when you get the new tiles. If itís a different tile altogether, I would try and at least buy from the same manufacturer since a 5-caliber for one company, may be different for another.
Good luck with the search, and let me know if there are other questions.
