help -- large format floor tiles with linear drain
I'm doing a mater bathroom with porcelanosa large tiles and a linear drain.
The shower is curbless. There will be one glass panel set on the left side, between the shower and the toilet. Drain is set by the right wall. The tile size is 13"x26". Now the tile guy did the following: he left a 3/4" gap by the threshold; and the grout lines are lined up every other row for the three rows close to the drain, and then follow a stagger pattern for the rest.
His explanation is that he had to have the gap in order to make the top of the tiles smooth because of the sloping. He did not explain why he changed the grout line pattern.
This floor just looks too awful. I want to see a consistently set floor, and without a gap at my threshold. My GC said it is just very difficult to slope the large tiles, so even if we start the tiling all over he doesn't know how he can make it work. He is also worried that ripping out the tiles now may damage the wedi board and the electric radiant heat we set beneath. My floor is already raised by 3" which I believe is more than enough for the slope.
Any advice? Thanks in advance.
