I am in the process of installing a new shower from the ground up on a concrete foundation in Florida. Shower will be 62" wide and 35" deep. I will be installing a mud bed and curb. There are three walls and I would like to make the outside wall out of glass block leaving a 28" opening. Can I lay the glass blocks on the curb?

I wouldn't. You want the blocks to bond to the curb surface using "glass block mortar".

How you address the marriage (and waterproofing) of the two (tile and glass block) depends on how you have things set up.:)

Waterproofing Options:

If it was me I would totally wrap the curb with KERDI Mat but I have it on hand all of the time.

The next option would be to use a liquid waterproofing product that you can paint on. Home Depot sells Custom's Redgard, Menard's sells Mapei HPG, Lowe's I think sells a Laticrete product but don't know which one. Laticrete has several really good liquid waterproofing products.

Glass block mortar will bond to all of them quite well.:)

A time saving tip on glass block----most brick yards will 'make up' the block for you in sections---all mortared together with a steel band.

Then you will only need to mortar the sections together.

I hire a mason for the glass block---he's the one that turned me on to that service--so thank Walter the brickie.
