10 Things Nobody Tells You About a Glass Block Shower

Blog Post - Opening image - 10 Things Nobody Tells You About Glass Block Shower | Innovate Building Solutions #GlassBlockShower #GlassBlock #ShowerRemodel

If you’d love to have a glass block shower in your new home or bathroom remodel but feel your builder, remodeler or building supply store are clueless about this specialty glass product, you’re not alone.

And when contractor and suppliers are ignorant about glass block showers, here’s a few things many of them will try to do.

  • First, they’ll tell you why you SHOULDN’T use the product.


  • Second, they’ll tell you their version of the ‘facts’ about glass block showers, even if they’re blowing smoke and don’t know what the heck they’re talking about.


  • Third, they’ll price the job crazy-high to get you to move onto a shower alternative they use all the time.


  • Or, lastly, they’ll tell you they don’t have anyone to install the blocks, so you’ll have to choose another product.

If you’re really serious about a glass block walk in shower – but need to know facts from fiction, you’ve come to the right article.

As a guy who leads a company whose been installing and supplying glass block shower systems nationwide since Moses was a child (OK – we haven’t been doing it that long, but my gray hair will tell you I haven’t fallen off the glass block wall yesterday either), I’ve heard many crazy mistruths about block walls and want to ‘set the record straight.’

So, in this article I’ve going to tell you 10 things I’ll bet your builder, contractor or general building material supplier– HAS NOT told you about a glass block shower. And I hope this article gives you the ‘straight scoop,’ so you can figure out (A) if a glass block shower is right for your project and (B) how to ‘sell’ your contractor or subcontractor that it’s not a difficult job to do or (C) will give you the confidence to roll up your sleeves and do it yourself, if you’re so inclined.

Without further delay, let’s look at 10 things nobody tells you about a glass block shower.

#1 – Knowing how much a glass block shower costs should NOT be an ‘ancient Chinese secret!’

I could give you the ‘cop-out’ answer and say the cost of a glass block shower depends on a number of factors. And these factors would include the following:

  • Factor #1 – Whether the glass block wall is straight or curved (note a curved wall is more expensive).


  • Factor #2 – Whether the glass block shower wall is prefabricated in sections or built block by block by a bricklayer (note – a prefabricated wall will not only be more cost-effective, but the quality will also be better than the bricklayer who normally lays bricks and blocks…not glass blocks).


  • Factor #3 – If the glass block wall uses one size/pattern of blocks or whether you have a multi-block design (note – the wall with one size/pattern of blocks will be cheaper).

And while all 3 factors above are true – they still DO NOT give you concrete answers to your question about the cost of a glass block shower. For that, I’d recommend reading this article I wrote called How Much Does a Prefabricated Glass Block Walk in Shower Wall Cost.’

#2 – Finding someone to install your glass block shower wall SHOULD NOT be difficult…. if you know this one important secret

Finding a mason contractor who is ready, will, and able to install a glass block shower block by block might be harder to locate than winning mega-millions choosing the Powerball numbers. It’s hard enough finding a good residential bricklayer (or mason contractor), and then trying to find one who is patient, skilled, and willing to allocate time to build a glass block wall (which are not as simple to lay as bricks and blocks) is even tougher.

So, how can you find someone to install a glass block wall?

Well –the first key is to buy a prefabricated glass block shower wall vs. picking up a bunch individual blocks which need to be installed unit by unit.

The prefabricated wall system has sections which are simply stacked on top one another. It’s super-easy way to even install a curved glass block shower – even if you (or your contractor) have ZERO experience with it before.

#3 – A glass block wall DOES NOT have to be one wavy block stacked on top another

It’s true most glass block shower walls have one wavy block stacked on top another. And while this pattern is timeless, simple to clean, can be made in a wide array of designs, but it’s not the most exciting look.

However, it’s nice to know you can lay glass blocks in varied patterns to create a look you can’t get with a clear glass shower enclosure.

#4 – You can save A LOT of money with a curved glass block shower vs. curved and bent glass wall

A traditional curved glass wall IS NOT a cheap date. However, with a glass block wall you can use blocks which are pre-curved (and can be prefabricated) to make a walk in shower with a curved shape cost-effective.

If you compare the cost of a 3/8” to ½” thick curved and bent glass wall to a glass block shower wall, you’ll find it’ll be 3 to 4 times more expensive. If you like the look of curved glass – or need a curved design to keep water inside a smaller walk in shower –glass blocks will save you a lot of money.

#5 – Glass block showers ARE NOT out of style  

Are there glass block patterns which have seen their better days … years ago? That’d be correct.

However, when you see glass blocks used at the front entrance of Coach stores across the country and also used in hip, urban upscale hotels you’ll see ALL glass blocks are not out of style. However, you do need to choose cool patterns which fit your interior design.

I think saying ‘glass block showers are out of style’ is just the easy excuse many builders/remodelers use because they aren’t knowledgeable about this product AND don’t know (especially if you try to do this job block by block) who they’re going to get to install it.

#6 – It’s much simpler to do a glass block shower if you buy a complete shower kit

Using a product your remodeling contractor or builder doesn’t work with every day is challenging. They may be worried how to make sure the glass block wall will fit on the shower pan. They may be worried how the interior shower wall surrounds will work with the glass block shower wall. They may be worried they won’t be able to find an installer.

The simplest way to take the complexity out of glass block wall installation, is to buy a complete glass block shower kit. And this kit will not only include the prefabricated glass block wall discussed in points #1 and #2, but will also include a solid surface shower pan made to work with the shape of the glass block wall and grout free shower wall panels. These products are not only stylish but reduce installation time (and labor costs) and make maintenance uber-easy as well.

#7 – Pay attention to the thickness of the glass blocks – and remember thin is in

Since glass blocks are substantially thicker (they’re either 3 1/8” or 4” thick) than frameless glass showers (which are 3/8” or ½” thick), they’re also sturdier.

However, when you’re looking at a shower which can’t be as deep as you’d like it, you’ll want to choose the thinner (3 1/8” thick) glass blocks. They create more room for showering, are simpler to work with (thinner prefabricated sections are lighter than the thicker blocks), and more cost effective.

So – when using glass blocks ask for ‘thin line glass blocks’ for a smarter purchase.

#8 – Install tile wall surrounds or wall panels BEFORE installing the glass block shower wall…and put wood behind the wall so it’s properly anchored

Just like any building material – doing a glass block shower installation properly is THE BEST WAY to make sure it lasts. It’s for this reason you want to put wood blocking inside the wall cavity where you’re going to anchor the glass block wall (so it’s properly supported).

In addition, install your grout free wall surround panels or tile shower walls BEFORE anchoring the glass block wall. This will make the shower wall more water resistant.

#9 – It’s best to use (the right) grout vs. silicone to hold your glass block wall together  

There are a lot of questions about the best way to build a glass block wall. Over our years of shipping prefabricated glass block wall sections around the country and installing them (or guiding the installation of them) our company recommends using urethane grout vs. silicone for the visible joints of a glass block wall. The reason is grout will make your wall stronger than silicone joints– and if you use urethane grout you won’t need to reseal the wall.

#10 – Glass blocks can’t be cut and come in standard sizes. Therefore, you need to design first BEFORE buying or building a shower pan or glass block wall sections

Most glass walls (whether you’re using glass blocks or tempered glass shower doors) CANNOT be cut to fit at the job site. And in the case of the glass blocks, the units are made in specific sizes and shapes which drive which finished designs are possible.

It’s for this reason you MUST begin with the end in mind. Design your glass block shower wall BEFORE buying a shower pan and/or buying the prefabricated sections.

You need to make sure the size of your opening is big enough to comfortably work for your family (and if you want more insights on the size of a shower opening read 5 Proven Questions to Get the Size of Your Shower Opening Right).

You need to make sure the wall is tall enough so no water comes over the top (I recommend a 10 block high wall which is 80” tall).

You need to make sure the end of the wall is finished with either rounded end glass blocks or waterproof materials like cultured granite or quartz.

Bottom line is you need to design BEFORE buying anything. And if you’re uncertain what type of designs are possible, call a glass block shower specialist to assist you. A glass block shower designer can show you (or send you) layout cards (like you’ll see below) so you can ‘experience’ how the glass block shower wall will ‘live’ before you buy it.

  • Sindi – your story is an inspiration – you had the determination to use the products you liked and make it happen! Thanks for sharing – and I’m glad you enjoyed the article – Mike

  • About 5 years ago I was having remodeling done of my home. I planned the bath as I was adding a large master suite to an addition which had been a family room with a tiny powder room.
    I am not a designer but I decided to take on this project myself and drew up the master bedroom, walk in closet and a much larger master bath. I knew I wanted glass block and at that time there was not much of that around but found a great closeout sale.
    I was really glad it all turned out so great. I found a general contractor to do all the work and picked out and ordered everything that was needed, including all hardware, cabinets, floor covering, toilet, sink, mirrored medicine cabinets, lighting, and quartz counter tops which had to be fabricated, and plumbing fixtures.
    I really enjoyed planning all of this and even at my advanced age (80+) and being a woman I think I did it better than some younger person.
    I am so happy to have found this article as all I hear is that glass block is “out” and that is why I was able to buy it on clearance. It was pretty hard to even find.
    Thank you for the information.

  • Mark – thanks for nice comments – I can tell you have a bit of a wacky personality like I do! I’m glad the articles have been of value to you. If I can be of assistance feel free to reach out. Mike

  • Hey Mike, wanted to swing by and say how much I enjoy your articles (so I am!). You make a relatively ‘dry’ (pun intended) subject usefully interesting. Actually, what prompted me to comment was your reply to James above. Genius!
    ps. I intended to rip out my never-used garden tub and expand my shower (utilizing glass blocks), but the Infernal Revenue ‘Service’ had other plans. Perhaps next tax year!
    Keep up the good work, sir 👍

  • Hey Mike, I just started my own bathroom and kitchen renovation practice after 20 years of working for the other guy. I was thinking of adding a glass block wall and this article gave me the confidence I need. I’ve done a few of these before but I think outsourcing to a pro would be in my best interest, and I can stick to what I know. The article was really insightful, thanks for sharing!

  • Thanks Jim, glad you enjoyed the article. I think it’s true nationally Jim that there are more bath remodels than kitchen – which makes sense since there are always more bathrooms in a home than kitchens! Mike

  • Mike, This article was well written and helpful. Just so you know, there are more bath remodels then kitchens, at least in this area. A retirement community. Jim
