The block was easy to install using the Provantage track and spacer system and the Corning silicone. Was able to put up a U shape bar base of 10 wide with Hedron corners and 2 blocks on the sides, by 5 high in a matter of hours. The Hedron spacer system is a little clunky. Ensure the spacers are fully snapped together to avoid any extra space. They still result in a few 'sixteenths' higher than the square block at each row. The full strength of the structure is not reached until the grout (silicone in my case) is in place and dried which takes a few days.

They are exactly what I wanted. I used the "ship-to-store" order method and was completely pleased with that process too. No shipping that way.

I made a stucco wall and placed the glass blocks in a random style for the outside of a walk-in shower. The blocks allowed light and looked great.

Hard to find product. Delivery was quick, pick up pain-less and the quality was everything I hoped for.

Rated 5.0 out of 5.0 by willdabeest most beautiful purchase yet.
The hardest part is the ordering and the framing but in the end was the easiest thing I've done to date.

Rated 5.0 out of 5.0 by Verified Reviewer Beautiful when installed - let's in a dancing rainbow to a small bathroom
Let's in light while still providing privacy. Installation in an old wall can be time consuming given the precision required to keep everything true for a single column. Had to purchase more rails and spacers than I needed due to only being sold in packs. Overall I'd do it again but question my idea of doing a whole shower wall sometime in the future. Bit pricey.
Pittsburgh Corning provides excellent, detailed instructions on their website. Be sure to read them and watch the videos. Their app for creating a shopping list is great!

Allows light to pass through and small amount of privacy; really pretty addition to my new bathroom.
