Since glass block shower walls are either 3 7/8" thick or 3 1/8" thick they would provide much more stability for someone falling into them than a 1/4" or even a 1/2" thick glass. In addition the walls are anchored into the side as well. The glass block walls are usually grouted and with a new "vinyl stacking" process actually have more stability than the old ways of doing glass blocks (check out the image below and the web link for more information).

Good point DreamBuilders! The new systems (like the image above) are actually more sturdy than the old block by block method and there is also no wire running through the courses that can rust down the road. Another benefit is with the vinyl stacking system the grout joints are only 1/8" vs. the block by block that ranges from 1/4" to 1/2".

Ooh, I like this very much. I wasn't aware that you could purchase a modular system instead of individual blocks. Any ideas where to find the systems in the US?

In Sacramento, Sierra Glass Block carries this. They could probably advise you where to purchase this in your location.

Thanks, DreamBuilders!
Innovative Building Solutions, thank you for the info on the size of the blocks and the images to show how they attach.
Have you ever seen someone color the grout and have it still look ok? And can these be used on curbless showers?

Zannej - with the system we have you can use any color of grout (we recommend using urethane grout..although sanded grout will work as well). I'll include a link to our site where you can find our modular system (we can prefabricate these sections and ship them to you as well):

Thanks! I like the gallery on your site.

Excellent Zannej - there are some fun things you can do with glass blocks!

so disrespectful to use buddha like statue to decorate the toilet...

The buddha statue isn't on the toilet-- its on the vanity. I don't see how that is "disrespectful". I highly doubt that Siddhartha Guatama would really have cared if someone put a statute of him in a bathroom.

it is in d toilet or washroom. ah well. I am a buddhist. so it's only me.
imagine undressing n doing your business in d same area with buddha.
n I defunitely wouldn't put d figure or jesus or mother mary in my washroom....

It can be weird what some people find to be disrespectful-- I know in some cultures, children are named "Jesus" as a sign of respect, but I've met Christians who find that "extremely disrespectful".
I think the important thing to take into consideration is the intent. If the Buddha had been put in a jar of urine, then I could see that being disrespectful. I think the point in this case was to make the room more serene. For some people a bathroom is not just a place to eliminate waste, it is their sanctuary where they go to relax.
