I think it will look nice.

You might want to grout a sample board of that mosaic. I think I had the same one. I was a little disappointed after it was grouted. It was really different because the light doesn’t shine they the sides. It’s a much “flatter” look if that makes sense.

Skip the mosaic tile.

It's a trend, and it will soon be out.

Your shower will look timelessly elegant without the mosaic.

It is not clear which other tile you plan to use in the shower of the ones shown in your photo, but the less variety in the space, the better, the cleaner and more restful the look.

Thanks! all of you for your reply

I am planning to use white 6x6 tiles through out the shower wall with a band of mosaic band (shinny grey and white ).

On the bathroom floor I plan to use the larg tiles with gray veining.

Your selections work well together; when you say square, do you mean a 6x6 inch tile for the walls? If that's the case, I would upgrade the wall tiles to something bigger.

yes It is the 6x6 on the wall, the second option I thought was same tiles as the floor without the mosaic.

That would work as well; you have you pick what appeals to your eye best.

Someone already mentioned this, but using a band of mosaic tiles is a trend that is on the way out. Unless you totally love that look, you might want to skip it.

We think you might want to consider skipping the mosaic tiles.
