I see that tile patterns are repetitive. You can set up one section and then copy/move it.

I realize that what I'm about to show is what may be considered an advanced technique. It's not a "one click" fix, but once the basic foundation is established, it is just a simple copy and move. The beauty of it is that it's completely editable!!!
It's based on the "sync" or "cloning" of smart objects. The principle is that once you create a shape, you can convert that shape layer into a smart object. This layer will serve as an "original" and then clones are made through copying. You can have as many clones as you wish. If you want to edit the clones, just double click the original and edit, then save changes, all the clones will update.
I was very interested in the tile and tile patterns. So I started researching. I noticed that tile patterns are certainly not limited to exact grids. As long as all the tiles are a evenly spaced in "even" pixels, then it should not be a problem. The only issue was the gutter/grout line width. This is solved with a stroke added to the "original" tile layer. If you need a 4 pixel gutter, just add a 2 pixel inner stroke to each tile. When two tiles marry, they form a 4 pixel gutter/grout line. This would be editable anytime you wished to change the width and color.
These are squares and rectangles in a 1000 x 1000 canvas. Theoretically, you can have anything from a 1px square/rectangle to a 1000px square/rectangle!
Imagine the possibilities!!!

The combos are endless!

Here I have quickly added a bevel & emboss layer style to the big green squares.

How about texture as well! These changes/edits can be made to any and all of the tiles just by updating the "original" shape layer!

Real stone texture...

Don't like the yellow tiles..............change them all quickly.

Works on triangles and polygons. (The polygons would require some filler triangles)

I have to admit that this was a huge pain to set up, but once I had all my "original" shape/tile layers established, the actual design went very fast. The Move Tool with the auto select on was the best way to select shape clones and Cmd/Cntrl + J to copy/duplicate, then move where I wanted it.
This is just an option for you to consider in the future.............it's not really for Ps newbys!
