Glass Block: There’s a Reason It Never Really Went Away

If you grew up around Baltimore, chances are you’ve seen glass block your whole life.

It’s been a familiar part of Maryland homes for decades — tucked into basements, built into bathroom windows, used in garages, and quietly doing its job without asking for much attention. For a long time, people thought of it as something practical. Something your parents’ house had.

But lately, I’ve noticed a shift.

The same homeowners who are restoring older homes, creating cozy spaces, and putting real thought into how they use their houses are looking at glass block in a completely different way.

And honestly, it makes sense.

We’re in a time where people care about how a home feels. It’s not just about having more square footage. It’s about creating spaces that work for real life — a bright basement office, a relaxing bathroom, a home gym, a place to entertain friends, or a quiet corner to unwind after a long day.

Glass block happens to solve a lot of those needs beautifully.

It brings in natural light without giving up privacy. It adds a layer of security. It holds up well. And it has a look that somehow feels both classic and modern at the same time.

That’s probably why it never really disappeared.

In Baltimore and throughout Maryland, older homes often came with glass block because builders knew it worked. Basements needed light, but homeowners didn’t necessarily want a clear view into their homes. Bathrooms needed windows, but privacy mattered. Glass block was a simple answer.

Today, people are finding new ways to use it.

I’ve seen homeowners incorporate glass block into modern shower designs, creating bright, spa-like bathrooms without feeling exposed. I’ve seen it used for outdoor showers, where privacy is important but you still want that open, refreshing feeling of being outside.

I’ve even seen people use glass block around sauna areas and backyard retreats — spaces designed for slowing down, relaxing, and spending time with friends. And that’s where glass block really starts to feel less like an old building material and more like a design choice.

Because think about what people are trying to create in their homes now.

They want places that feel special.

A backyard that feels like a getaway. A bathroom that feels like a spa. A basement that doesn’t feel like a basement. A home that has character instead of looking like every other renovation.

Glass block fits into that perfectly.

It has texture. It has history. It catches light in a way a regular wall doesn’t. It adds something interesting without taking over the room.

One of the reasons I wanted to write about this is because I’ve seen firsthand the difference that experience makes. Ed Murphy has spent years specializing in glass block, and that kind of focus is becoming harder to find.

There’s something really refreshing about seeing someone stick with a craft that many people thought would disappear. For a while, glass block felt like one of those features that belonged to another time — something we assumed would eventually be replaced.

But maybe we were wrong.

The truth is, glass block stayed around because it works. The same things that made it popular years ago are the reasons homeowners are choosing it again today.

It brings light into spaces that need it. It creates privacy where people want it. It’s strong, reliable, and has that vintage architectural look that gives a home personality.

It feels nostalgic without feeling outdated.

And that’s one of the things I appreciate about Ed’s work. He isn’t just installing glass block — he’s preserving a specialized skill and bringing it into the way people live today.

It’s pretty cool to see something we thought was fading away become one of those timeless home features that just keeps making sense.
