that was so nice and helpful of you, Kevin. it appears to me that the only thing changing is the grout, which looks wetter temporarily. i wonder why on earth my tile is also getting so wet. by the way, your shower inspired me and my guest bathroom floor is now a black border with white square marble mosaics and the shower floor is a smaller size black marble square mosaic. it looks really sharp.

Ok - I get it - I should not have expected to get what I paid for and was specifically told by my rep I would get ;-) - a superior primed trim that should not require much prep work and would provide a near flawless finish - not my words - hers. She also specifically said it would save time and money painting. I now know for future reference - if I were ever to rebuild a whole house again and I'm not! -that I fell for a good sales job. My GC seemed to agree with her but he is not a painter. I knew going in that he has strengths and weaknesses - I would say trim finish is probably not a strength but my builder cousin came out to visit during the framing and said it was about as well-framed as we could expect it to be - a top notch job. I'd rather know the bones are good and deal with some finish issues. My painter did say it would require another coat of primer and they did the typical filling and sanding before priming and painting. It turns out it is a sheen level higher than eggshell so perhaps we will go with eggshell if the brushing putty doesn't do the trick on its own. I will certainly speak to him about why he did not notice the ridges when it seems that 100% think he should have. I did not notice after the primer he put on when I stopped by the job site - during our weeks of rain here in CA.But I wasn't painting it. He noticed at the first coat of the higher sheen finish and that is where we are now. One piece has now been sanded well with two grades of sandpaper and primed and painted and the lines are still there. This was done by my GC's foreman - he has specialized in restoring original moulding in historic homes and does beautiful work so I have now had a second opinion - so to speak. It does sound like I am ahead that my trim rep believes I received bad trim and is going to refund my money. Otherwise I would have paid the labor cost for all the sanding myself - if the painter had noticed right away and taken the time to do it - and still had lines in my trim. Now I know the sanding doesn't get rid of the problem and can go straight the the brushing putty and hope for the best. I honestly don't really care about a "glass" finish - I just don't want to be sitting in my beautiful new living room surrounded by doors and floor to ceiling windows with stripes running down them! I'd even take a couple drips for an overall smooth appearance at this point. THanks for the feedback - even as I seemed to have trouble "getting it."

I wonder if I carve a little channel into the grout joint where it meets the wall if that will help somewhat? Where I have the red line marked. Maybe even raking away the grout build up there. The shower below is my own and me and my four girls all use this one shower. The grout takes a beating from cleaning but the shower niches do not hold water. In the large niche with the light I purchased a larger tile to ensure that the niche bottom was in one piece of tile. This is key I think for any shower sill or niche. If you are going to have grout lines less is more

@User because I was most concerned with discussing the materials, my drawing is not 100% correct (and I wasn't that handy when creating it, ha). The glass wall will actually angle into the area before the opening starts, so the walk-in part is more of a straight walk-thru, turn right and the shower opens up due to this angle. Probably 6' from shower head wall to actual opening.
