The tile done in the second picture of my first post is actually 6 x 36 wood look porcelain tile ( a different company though). It is laid the same way as mine. It is was done by the main tiler and looks beautiful. It is 1/8 grout lines no lippage at all! I would post a picture of it but it is all covered up right now. I was harsh about the second guy helping him because he had already cut a lot of corners with other things. He wasted a lot of tile getting cuts wrong - which the other contractors themselves were complaining about and bringing some to my attention. Some really bad cuts I noticed he tried to pressure me in to accepting - when I almost caved another one came to me and confirmed it was not good. He basically tiled my kitchen and left the molding on the wall. On top of that all the cuts against the molding were jagged. Like one part would up against the molding and the farthest was .5 to an inch. When I asked what would happen with it he was just answered that it would all be filled in with grout. Dark grout that would make it stand out even more. EDIT :: Here is the link to her tile: https://www.lowes.com/pd/CERAMICAS-TESANY-Tahoe-Gray-Wood-Look-Porcelain-Floor-and-Wall-Tile-Common-6-in-x-36-in-Actual-5-82-in-x-35-29-in/1000379225 Maybe her tile - despite being larger, allows it. If that's the case, I can wrap this around my head and get over it. However, if hers is similar to mine and the good tiler is able to do it without lippage in that layout with smaller grout line - I would like to go for it. EDIT:: Is this another possible solution. When they relay it Would relaying it to overlap in thirds instead of 1/2 help. I am not to particular about that if it will help me get the smaller grout lines.

Heed MillWorkman's advice. Any change of plane, whether it is wall to ceiling, wall to floor, wall to wall, etc.. will almost always require caulk of some sort. !00% silicone for anything around water. In other areas, a siliconized caulk, or paintable 100% silicone caulk can be used. I have done a lot of painting, either for myself or others, and I learned from an experienced pro to put a light layer of caulk in corners, around mill work, and wall to wall/ceiling/floors to prevent the paint from cracking/splitting. Just my 2 Lincolns worth.

Maybe do the 2 bedrooms with carpet and then just match the othere 2 spaces with the same tile. I think trying to match and miss the laminate would be worse.

You might want to put all one color subway tile with a decorative accent band in middle.. grout on the floor of shower and bathroom does not stay cllean, so use darker grout
