More Bathroom Plans...

Our bathroom is coming together. We are a backwards sort of people, so we did the floor first. Here are more plans:

First:
This window in the shower needs to go. It is rotting, and covered with a small piece of vinyl shower curtain. Definitely not attractive.

The plan?
To replace the window with glass blocks.

The problems?
The window is 24 inches wide. Glass blocks are 8 inches wide. If I put 3 blocks in the window, there is no room for mortar. Also, it is 35 inches tall. What should I use to fill the gap? Must research this further.

Second:
I HATE the tub surround tile. It is fake marble. FAKE, FAKE, FAKE. So fake that you can SEE the pixelation from the printer that created the pattern. Each tile is exactly the same, too.
Even WORSE than the fake marble tile is the accent tile. It is a baby blue/slate grey concoction that gives the appearance of being rope.
They do not match our bathroom at all.

The plan?
To carefully chip out the blue accent tile and replace it with slate tiles cut to fit. I'm trying to decide whether to do long pieces of slate or short (1 inch) pieces of slate.


Third:
Our bathroom needs more storage.

The plan?
I am going to build two extensions to the vanity that will fill in the area between the vanity and the wall. They sell cabinet doors for fairly cheap, so I will be able to match the existing doors.
I'm going to put marble countertops on top of the two units, to "match" the fake marble shower surround.
I want them to look different than the existing white counter, since they will never look like "part" of it.

Fourth through Seventh:
Replace the shower curtain and rod.
Finish the doors.
Finish the molding and trim.
Paint and texture.
