as luck would have it, I am a warehouse manager for a Vinyl flooring distributor. I have heard through a few installers that they did have an issue with shrinkage. I do not know if they have solved this issue or not.

Centiva is installed into the Empire State Building in NY, where you buy your ticket to go up to the viewing gallery and it looks fabulous. No shrinking at all. In fact, regarding shrinking, Centiva is the only manufacturer to incorporate fiber glass into its products, which eliminates shrinking. I think Centiva is also the only (or one of the only) manufacturers that actually makes luxury vinyl flooring in the USA! Hope this helps.

Luxury Vinyl Tile is somewhat dimensionally unstable. Moisture in the substrate you are installing it over, or in the adhesive you are using to install it, can exacerbate that instability. The shrinkage is generally more notable in luxury vinyl plank, where the shrinkage factor is multiplied over the longer lengths of plank flooring. Suggest that you use a transitional pressure sensitive adhesive, such as Taylor 2091, using the wet-set method (adhesive still wet when you set the flooring into it) to install the flooring. That adhesive dries with exceptional sheer strength that inhibits the plank from shrinking. Only way to go in large commercial projects.
