4-1/4" and some larger wall tiles have bumps cast in that act as spacers. Unless you want a larger gap, no additional spacers are needed.
Whether your particular tile has them is uncertain. They're often necessary to prevent sagging with heavier tile while the mortar or mastic sets.
Answer from isherwood on Stack ExchangeVideos
I've tiled floors before and am very happy with the way they came out, but this is my first shower.
I'm using a KBRS shower slope base and redgard waterproofing membrane.
I've asked these questions at the tile store and have watched a bunch of videos and of course get different answers. I'm interested in seeing what r/homeimprovement thinks.
The shower is about 61" wide by 33" deep. The opening for the door is 34" so the front wall is about 34" open and a 27" wall.

What height should my shower curb be?
-
Should I tile on the outside of the curb? The curb will have a marble cap on it, sloping inward, and the inside vertical of the curb will be tiled. But the outside vertical (about 3") is facing the rest of the bathroom. Is it OK for that to be covered in drywall, or should it be tiled too?
-
Inside corners - how much of a gap do I leave from one wall to the other when they meet on an inside corner? Or do I just butt them up against each other since I will be caulking the corners anyway?
-
self-spacing or no? Many 3x6 subway tiles have built in lips that act as 1/16" spacers. Or I could purchase tile that needs spacers. it seems like the built-in spacers would be quicker and easier but I'm just wondering what opinions are on it.
Thanks!
I’m seeing conflicting guidance on what spacing to use with these tiles; and if spacers are required.
The sides have a slight bevel such that the tops are just under 1/16” apart. In my testing with 1/16” spacers, the grout line ends up at 1/8” which is visually much thicker than I prefer. I’m trying to minimize the grout lines as much as possible.
What would you do in this case?
**Tiles are 2x8 inches. This will be a kitchen backsplash
My contractor installed 3x12 tiles in my shower, and while the grout lines are straight, the tiles seem to be unlevel. I don’t recall seeing any spacers used like he did on the floor. He’s blaming the wall for being uneven but it’s all new! I have the worst luck with contractors, even with reviews!

See comment below with new videos of replaced cement board
ooof so the lines aren’t angled, each tile is angled individually. That’s unacceptable craftsmanship to me. Is he paid out?
So I got the owner to redo it all today, ripped it all back down the studs. He has all new cement board up, I’m gonna share a video later. Anything I should be looking for before he comes back tomorrow?
