Most of the window is alright but there are several places where the grout has cracked or broken off like the right side of the picture. There are a couple place where the entire joint has broken off and dropped into gap in the middle of the blocks. One joint in particular, shown on the left, has broken into pieces. Even the plastic spacer has broken. In that particular one it is apparently broken on the outside as well and wasps are coming in with some dead inside the crack. I am confused about a few things: Should this grout be replaced with Silicone, a Glass Block Grout, or something else? If grout, would I need to remove all of the grout and re-do the entire things? Do I need to try to remove the pieces that have pushed into the gap (Not sure if they will fit trying to pull them out? Do I need to insert a new Spacer or just fill the space (seems like it would be difficult to get them in there)?

Three years ago when I started the project of doing over the basement into a studio inlaw I purchased a prefab neo angle shower that included the glass doors and base. I had planned on doing a tile back to give it more of a custom look but now I'm wondering if I should go a step further and do a custom pan as this pan is 6" in height which is really unnecessary now that I trenched out the plumbing into the floor. I would still use the glass doors and trim. I guess I am looking for some input. Would I just be making more unnecessary work for myself or is this something people commonly do?
