Shower floor tiling/grout question

HU-739194839

last year

I had old tile removed from the shower floor and replaced with 24x12 porcelain. Shower wall tiles stayed the same but regrouted. We were told the whole thing was sealed. We waited 3 days before using it. When the grout lines get wet they turn a darker color. We read online that the water should bead on top and grout should not change color. The tiler said it will change color until it's been resealed a couple more times. He is well reviewed and responsive, but due to other small issues I don't know who to trust. Can anyone tell me what's going on with the grout? Thank you.

Can you share a picture of your shower floor?

I am not a pro, but two red flags leap to my mind: unless you have a linear drain and/or have envelope cuts in the tile, 12x24 is too big to provide the proper slope.

Second, how was your shower waterproofed in the first place and during the floor replacement? Many waterproofing methods would be ruined by replacing tile, and are not able to be repaired one section separately from another.

Stop reading on line as not all situations and or products are the same. Typically replacing just the shower floor tile is a recipe for a hot mess. You need to describe exactly what was done and how. Demoing tile usually compromises the pan waterproofing and the walls having the tile left in place is worrisome as well as "if" he redid the floor waterproofing how did he tie it up the walls as the waterproofing is supposed to be?
