I haven't read everyone else's responses, so I may be repeating but here is our experience with it.....
We desperately needed new flooring for our kitchen/hall/bathroom down stairs. I wasn't in a position to do ceramic tile (I did my bathroom walls and tub surround myself in ceramic tile a few years ago, so I knew what was involved... but we would need to have cement board installed on the floors before we could install ceramic.... too much $$ and time, so we didn't do it).
After some reading/thinking we decided to go with vinyl tile (at least temporarily). The things I REALLY didn't like about vinyl tile I had seen in the past was.... #1.. The SEAMS. I hate seeing those cracks/seams. #2.. the extreme SHINE. and #3... the peeling corners. So we had to find something that took care of those problems.
We bought a commercial grade 12" vinyl tile at Home Depot. It was a very matte finish that truly looks like ceramic at a glance. It has grey "grout" lines around the edges. The day we installed them we did it on a very cool late winter day. We turned the heat waaaay down and opened a few doors to cool the house down. We installed the tile EXTREMELY tight to each other. And then that way when the house warmed up and the tile expanded (every so slightly) the seams would press together. It worked well and our seams are EXTREMELY tight.
Before we installed I scrubbed down our existing sheet vinyl flooring, super glued down anyplace it was lifting or buckling, and then prepped the floor with a product we bought at HD (it looked like watery white paint and you put it in a section at a time with a roller). In going through the boxes of tiles we discovered 5 different "patterns". We would open several boxes at a time, separate the tiles by pattern and then tried really hard to be sure that no two like patterns touched each other (which was tough sometimes!). We spun the pattern around every time and I think even with carefully looking our floors look like very random. I don't think that the repeating pattern is at all noticeable.
Any place where the tile met woodwork (like around a door frame ) it was really tough to cut (this tile is REALLY thick) and we couldn't always get it to meet up tight, so after it was all installed I custom mixed some waterproof caulking to match the grey "grout" on the tiles and I filled in everywhere where tile met edges and wood (around door frames, along the edges of my kitchen island). We removed what we could before we tiled (all of the baseboards and the toilet) but we didn't remove any door trim. Where the tile met the carpet edge, we used a pry bar to lift the metal carpet edge and made sure that the tile went just slightly under that edge. Then we hammered the edge down again.
This was 4-5 years ago and I am still VERY happy with how the tile has held up. We do have one spot where I think that the tile is slightly discolored from the sun and a few that are a bit rough from kitchen chairs that got dragged back and forth a lot.... but we saved about a box and a half of extra tiles and I may decide to replace just a few of these tiles. We have had NO corners lifting and the original matte finish looks SO much better (IMHO) than shiny tile that has been worn and dulled over the course of years.
I can't quite remember the name brand and I am not at home, but if you are interested I can check when I get home next week. Let me know if you have any other questions.......................P
