They way I have seen them is the inside of the niche tile butts up to the outside piece

Use a chrome edging

I bought a very special bonding primer and had color matched. There was no way around mine bc edges were just unfinished. Mine was a step down at entry and I would have exposed edge no matter what! Came out great and traffic has done nothing. However, yours is in a shower so I'm not sure if that's ok? I mean we paint siding material so maybe an exterior paint? If the tile has been set maybe it's an option but I hope pro finishers weigh in with this option!

Ps-it's actually that tile in my profile photo on that very edge on the "rise" face.

Better shot. Again mine wasn't in wet area.

We usually do it this way with a bullnose tile on the sides overlapping the wall tile. Or a trim piece of some kind.

There are two niches side by side so I am really hoping the niches will look uniform in the end. At this point I am hoping we are track with this bathroom remodel.

I had never paid any attention to what my tiler used, but it looks like he used bullnose tile to give a somewhat finished look. It looks good to me in person.

The next step will be the border. However, to keep life simple I am considering not adding a border to the shower. Any thoughts?

Thank you to all who commented. I feel a lot more confidant in our remodel. Thanks again for the support.

No border. I'm my opinion, it was a fad that has now become obsolete. I clutters and is especially going to make your shower walls look extremely busy given the 2 niches. Keep the lines clean. My 2 cents

i suggest using bullnose or a Oil Rub Bronze Schluter. It will be a much cleaner look

Good news is that we took your advice and nixed the border. I am glad we did.

Now we are in disagreement over how the floor tiles should be placed. I feel like they need to be a consistent grain. However, my husband wants to have them going all different directions. Which way would look best? The picture shows them all different directions.

I prefer the grain going the same way as well as you can.

If this is for the shower floor, I say square or on a 45

I have a question about the tile on the shower curb. My husband has it matching the brick pattern on the wall. Does anyone have any thoughts or suggestions?

It is not possible to eliminate all raw edges. However, it is best if you can finish as many edges as possible. Not only for your enjoyment but better for resale down the road.

We like to finish our edges with a bullnose edge or with a small pencil liner. It gives it a nice finished look.

Thank you for the comments. My question about the tile layout on the curb. Should that tile layout have been symmetrical or was it ok to have it match the wall?

Nothing wrong with it matching the walls.

Which grout color would look the best?

I prefer when there is less contrast between the grout and the tile, so it looks like the bottom one to me. Hard to tell on a computer screen.
