About Glass Block

Molten glass was first injected into glass block molds in 1937, and glass block has been a staple of contemporary architecture ever since. Although other building fads come and go, glass block continues to capture the imagination of designers, builders and homeowners.

The smooth, impervious nature of glass block makes it a fantastic substitute for ceramic tile in a shower. With its patterns and sparkle, the block itself is beautiful, and it allows natural light to flood through the walls into the shower.

Before you begin, stock your tool belt with plenty of patience. Glass block work is a skill that’s very aggravating to master. Blocks can’t be cut or trimmed, and their nonabsorbent nature makes mortar work especially tough. But if you don’t try to rush the job, your work can look as good as any professional’s.

A note on installing new bathrooms: Before you run out to buy a truckload of glass block, be aware that converting a bedroom into a bathroom requires extensive work beyond the plumbing. You may have to reroute heating ducts, eliminate existing windows, shift electrical outlets and remove possibly load-bearing interior walls. Run the design by a building inspector to get the necessary permits and inspection schedule. One other warning: If you plan on taking long showers using two shower heads, you might need another 40-gal. water heater.
