I just completed my second install of Congoleum Luxury Vinyl Tile. When selecting grout I was warned by the retailer about grouting problems, but I did it my way - only grouting three tile sides or 4 feet (1.22 m) at a time - and had absolutely no issues. The first floor was done two years ago and we enjoyed the look and warmer, more-comfortable feel of the luxury vinyl tile so much that when it came to choosing flooring for the second bathroom it was a no-brainer. We have not seen any of the issues claimed by other reviewers. The only disappointment was that Congoleum discontinued the AU11 product that we used before, so we switched to RB10.
