Potential problems with 1/16 grout joint?
I'm using 12x24 rectified porcelain tiles in a shower. The tiles will be stacked on top of each other. I would like to use a 1/16" grout joint.
I've read that lippage may be a problem with a small grout joint and large tile. But, since I'm stacking the tiles, I presume lippage is not an issue in my case. Is this correct?
What problems might I run into with a smaller grout joint such as 1/16" with 12x24 stacked rectified porcelain? I would hate to have a bad-looking tile job due to a small grout joint and will go to 1/8", if necessary.
