Luxury Vinyl Tiles are composite tiles which are made primarily from crushed up porcelain. They have been gaining popularity over the past five years and are a good alternative to standard ceramic tile.
One of the advantages is that LVT is roughly an eighth of an inch thick compared to ¼ to 3/8 inch of ceramic or porcelain. Additionally, vinyl tiles are adhered with glue as opposed to thin-set which is less thick as well.
The most beneficial aspect of a vinyl tile installation is that the adhesive and latex grout (if used) is somewhat flexible and if your house moves during the different seasons, it does not tend to crack or separate like ceramic tile can. Most of my vinyl tiles are 15 to 16 inch squares. There are a few that are 12 x 24. The surface is very tough, much more scratch and gouge resistant than a sheet vinyl product. Pricing is comparable to a higher end sheet vinyl or laminate floor.
LVT can be glued directly to concrete, to wood underlayment, or even right over existing sheet vinyl flooring (if properly embossed)
