Grout joint width is both personal preference and dictated by the type of tile per industry standards (size and material). Most tile has specifications including the required grout width. If your tile allows a 1/8" joint (or smaller), you were within your rights to request it, and it should have been set to those specifications. Always good to get those specs in writing. We almost always set to the minimal grout joint.

Thank you so much for the reply! It is very appreciated.

I am using this tile: https://www.homedepot.com/p/LifeProof-Sierra-Wood-6-in-x-24-in-Porcelain-Floor-and-Wall-Tile-14-55-sq-ft-case-LP31624HD1PR/304207361

To my knowledge wood looking tile is usually placed closer to better resemble actually wood. It is why I choose it. I just hate stepping on wide grout lines after a shower. Also to my artist eye.. I can tell that the lines aren't consistent which was another thing a really disliked. I just needed some confirmation from the professional realm that I am not overstepping by pressuring them to redo the floor. For one it's not that big of a space. They also accidentally bought double the amount of tiles/grout I needed. So it is not like we don't have the materials here.

I am attaching two pictures. The dark drown floors (with the flip flop) are my floors with the 1/4 wide grout lines. Also some inconsistencies in width.

The other is my sisters. You can see hers start to have inconsistencies. The correct side is done by one tiler the other was done by a second of their that is helping him. Also the small grout lines on hers is what mine was supposed to look like.

The problem was the second tiler and he won't be returning. Now I just need to get his work rectified.

Oops, now I see your photos. Unsure of the lay out pattern based on the close up photo. And the grout color? Would have gone darker and closer to the color of the tile. Lighter will highlight the grout. I think the grout color may in fact be your biggest problem.

Oh the Grout color is pretty dark. It matches the tile very well. The lightness is actually just dust and specks. I will get another picture of the layout and the grout color.

Pictures. The dark spots you see in between the white is the actual color. I tried to sweep the grout and take a pic, but it was way too much dust that messed up the picture.

Funny enough.. I was considering if I should do different grout if I get them to redo it. but I was thinking of bearing the extra cost of epoxy. However, if they have issues with this, asking them to do something that takes more work didn't seem like a good idea.

But maybe I will take the chance to consider a different color. I wanted a walnut color that had a bit more brown it it - but they couldn't just pick it up so he told me he couldn't get it... I am just now realizing they just didn't want to order it.

would you prefer lippage or larger grout lines? I would pick larger grout lines. With your tile choice and 50 percent offset a thinner grout width is asking for lippage.

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:

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.

To have narrow grout lines:

First, the tile has to be relatively flat and rectified. Not cheap box store stuff.

Second, a bunch of time and money needs to go into making the subfloor flat. You haven’t once mentioned the floor prep that costs as much or more than the tile laying.

Third, a lippage management system is a best practice. But it cant fix box store potato chips.

Fourth, the installer has to know and explain all of those conditions.. Up front. There is no substitute for hiring the wrong guy.

Fifth, all of that skill, knowledge, extra prep, and extra care, costs money. Double the cheap guy’s quote. As a start. You cannot receive that which you are unwilling to pay for.

On another note- back tot he grout color.

You are not the first to tell notice something off about the grout color. My mother asked why it was speckled like that. I was under the assumption the color variation would be dusted and cleaned away. However, I have some how ended up with two tone grout.

The left side is what it is supposed to be. The right side is ... just messed up.

To make sure I took a clean brush and wiped that center grout line. It is already drying with the distinct two tones. I'll double check it when it is completely dry.
