and i'm sure the manufacturer says to do NO more than 1/3 offset. This is why.

What size are these tiles, 12x24? I can't believe he used a 50/50 layout with this size. TCNA standards are anything over 12" long (and smaller w/other tiles) should be done w/no more than 1/3, sometimes less.

If your tiler is telling you have uneven walls, then why didn't he fix them, or tell you to pick a different layout? A good tile setter will fix these things or advise the homeowner to pick a diff tile.

a good tile setter also knows these larger format tiles should be laid in a 1/3 step layout so that the bowing and lippage is not as noticeable.

see what the manufacturer of this tile recommends for layout and grout joints.

if the thinset is already dried, pulling them off may ruin the underlayment. hard to say since I don't know what's there.

this is why some old school tile setters float the walls w/lath/mud. this way they control the levelness/plumb of the walls.

The brochure for the Forum tiles shows roughly an alternating 10/90 and 20/80 offset install for both walls and floors. I couldn't find an installation data sheet.

Actually tiles is 30% offset (it is the 12" x 24" tile). It's disappointing after the amount of money spent on this it is turning out this way. I knew a 50/50 layout is not the way to do it even though all the store dispays have it set up that way.

The fix is to remove it and source better tile.

The installer should have put the breaks on and refused this tile order when he went to the vendor to pic it up and pay the balance. Since the tile installer bought the tile approved the tile and installed the tile id say he or she is responsible.

Wait, You didnt source and buy the tile yourself did you?

I just dont know any professional tile installers that would go ahead and install this material, usually its A novice or handyman that havent been down this road yet, begs the questions who did you hire and what installation standards are referenced in your agreement? who bought the tile?

Someone else had posted earlier and had misquoted the TCNA standards I thought id clear that up for anyone serious about the tile trades and standards and is getting misinformed on houzz(surely well intended).. Understanding the TCNA and how ANSI is implemented is indeed a little tricky if you not in the tile trades but to clarify

.

It is ANSI A137.1 that sets the spec for Allowable warpage in tile as being acceptable from MFG. While they may make recommendations on how to minimize lippage, its the tile mfg themselves that shall spec their products stagger. In many cases the tile gets sold and its already not in ANSI tolerances from the get go. One more reason I as the end installer must control the tile purchase and selction or pass on the job.

Sadly, there is no fix for this. The tiles should have been checked for flatness. The defects you see are primarily the result of the bowed tiles, rather than other issues. This could have been minimized with a stacked pattern as long as the tiles were uniformly bowed, but the best approach is to not have to deal with this. I'm also concerned that your tile guy didn't bother to fix the walls beforehand, although this would not have allowed you to avoid most of the problem. However, it does speak to the fact that he is less than professional.

Hallet, no I did not check. I really didn't know much about tiles until it came out looking like this. I know the walls of my house aren't perfect but I wasn't expecting tile to be warped. Lesson learned :(

DS Kobi,,thank you for pointing that out. from the pic it looked they were 50/50.

do you have any leftover tile ? see how they look sandwiched

TFW, thanks for clarifying that. I only posted the layout recommendation. (and the tile setter did abide by that). If these tiles actually do meet or come in below, allowable warpage, then what?
