We had Congoleum tile professionally installed, because it was advertised as having superior durability. What a joke!
This stuff breaks, dents, and chips more easily than any other tile I've ever seen. A child's toy dropped on this tile caused the top layer to actually break and flake off. After just a year, the floor was thoroughly cracked and broken, with missing pieces large enough to see the concrete foundation through. This tile is so bad, there's even a "Congoleum by Duraceramic tile sucks" Facebook page (that I found; I didn't create it).
Finally, we are having it replaced with proper tile. Too bad it means we have to pay a second time to have our floor tile done because of Congoleum.
Monetary Loss: $1400.
