Install issue or material issue* thanks in advance for the advice!

Can't tell a thing from your picture. The whole back wall is mosaic? Get some light in there, and more pics

it's an install issue. you can see the problem with the floor too. on the floor all you see is the square sheet the tile was set on. the mesh sheets should, at minimum, be staggered and if possible some stones should be pulled off the sheet and laid individually to help it look "not square" lol.

did you pay someone to do this?

Sometimes clients think that mosaics are an easy install; they are not. You need a top notch tile installer to set these up properly. They should have been better mixed between the boxes as well, grout will not change anything.

You needed a better tile setter and IMO you chose a very wrong tile for a shower wall all those grout lines will be a PITA to keep clean .

Holy MOLY that's a lot of grout in a shower. Most people are trying to MINIMIZE grout and cleaning. Same for the floor - more grout, and I've never understood that bumpy stone floor look- I can't see it being comfortable on your feet or easy to squeegie and keep clean.

Ultimately - you CAN get mosaics to look right but it take a ton of skill and I really questions this application.

Wow I blame the tile- the blend of colors is not consistent sheet to sheet. The tile setter tried to mitigate it by offsetting the sheets (versus installing on a grid) Where did you get the tile? Online, big box, or specialty tile store?

Speciality tile store. The brand is Jeffery Court

I really think that mosaic is too small--it looks pixelated.

I would get your salesperson involved then. Something was wrong with the tile. Generally installation is acceptance but this looks pretty egregious

. Mosaic glass tile from Oceanside Glass - no visible sheets. Different product than yours obviously but it can be done.

Yeah with natural stone tile you have to be very purposeful in blending/placement, and it looks a little careless how there are big blocks of whiter mosaic. I think grout will help with color continuity but it won’t fix the blotchy install. When I buy marble tile I search all the boxes to get stone that matches so I have to worry less during install and get a more cohesive look
