I like your first photo of the herringbone on a diagonal.

First

it only makes you dizzy because of the graph paper. on the actual floor its the difference between checkerboard and diagonal checkerboard.

so, where is the door?

you should decide which you like based on which view you like best when looking in the door, not based on how your ceiling light fixture will experience it.

The first is the best!

The first option looks the best.

I love the first. Have a hard time with the 2nd one.

Another vote for the 1st.

The first drawing is the best option

Hmmm...Hard to tell without seeing the tile in question...I'm a fan of 90 patterns myself but, it really depends on the tile for me........ just don't do this....

I'm pretty sure It is a herringbone on a 90 in the second picture. The dizzying picture I posted above is a Chevron kind of, so not actually a herringbone..... but his two examples are I believe...

Thanks, everyone! Strong consensus, that's for sure. I considered the second just because I'm not sure how experienced my contractor is with herringbone pattern, but I agree that the first one jumps out as the winner (though yes, the blurriness of the second drawing and the graph paper don't help its case.) The door is the lower left side of the drawing and opens in to the wall at the end of the shower. Not the best but it's what it is... We thought it was funny how the second one seemed like a path right to the toilet. (Of course, there's 24" of play in where to actually place the pattern - it doesn't have to be where I put it.) I like the point that we aren't going to be looking at it from the ceiling fixture perspective!

This is the tile, in Pearl color

Second - it makes the room look larger. And go with a darker toned grout if it's supposed to resemble a wood floor. But I would lay out the tile in question and try out different options live.

That's a tough one. Definitely lay some tiles out. That's a beautiful tile you've picked and will probably look great both ways. Not as easy for me to make a call without seeing it in the space. Good Luck!

The first one----it looks more "organized". And the main difficulty with installation on a 45 is all the wall cuts. Once the pattern is centered with the first few rows it's no different the the 90 degree as far as setting.

Descending opinion here - I prefer #2. Based on nnigrt's brilliant observation and the location of your entry door, the fact that with option #1 upon entering you see a single repetition of the pattern, it may tunnel your vision and make the passage between wall and shower to appear narrower than it actually is. Not sure if i'm explaining myself clearly here, sorry. I think that if you opt for #2 but make sure that the first tiles are parallel to the doorway, you'll open up the room visually.
