Trinity Cavan Matt Tile - A tile defected for bathroom and floor use

I purchased the Trinity Cavan Matt tile from Italtile. I'm very disappointed with the tile. It constantly looks dirty, no matter what you do! I have steam cleaned I have used grout off and I have used their Easy Clean.

I have been told it's not a defect of the tile and told to use various cleaning products to clean the tile. If it weren't such an expensive tile, I would just knock it up.

They said to clean it once off with grout off...I have done it more than once and marks still remain. Grout off is acidic and has damaged my black shower waste (because it is kind of hard not to get it on there while cleaning). It can also only be cleaned after the trap is fitted because it has to be grouted around there....They say it isn't a defect but a tile that constantly looks dirty no matter how much you clean, is a defect...and obviously when you clean it "once off" with grout off it is kind of hard not to get it on the grout that then also leaks again onto the tile, creating a vicious staining cycle.

I believe this tile isn't suitable for the floor and I would appreciate at the very least being refunded for the 4sqm in my bathroom so that I can replace it with a suitable floor tile....I had no problem with my wall tile.

Whilst writing this review I went and attempted the grout off again...works in some parts but not ALL...and like I said again spreads the grout again...
