Built With Foam

Built With Foam is a proudly US Veteran-owned manufacturer based in Houston, Texas.

We know what you need to make a job successful. Our team has a combined 90+ years of experience in building trades including tile installation, high-end homes, historic properties, and commercial spaces.

Over our decades in the industry, we’ve witnessed the evolution and prevalence of foam products on the job site. Custom foam is not only cheaper as a building material, but it cuts down on labor, substantially speeds projects, and can remove a lot of the typical daily hurdles. We’ve put our experience into designing and manufacturing quality products which can make the lives of our fellow tradesmen and tradeswomen much easier.

Exclusive Products

Our exclusive Tub Arch™, Shower Arch™, Tub Dome™, Shower Dome™, products eliminate the need for complicated, time consuming, and expensive framing along with the usual jobsite “discussions” that inevitably happen.

Shower Wall Shims

Our shower wall shims are color-coded for thickness for easy, accurate installation. Each kit averages over 900 shims with 7 different thickness options for every job. Included in your kit is a measuring gauge to facilitate
installation – paired with a level, straight edge, or laser, your shower wall shims will have the best fit possible!

Why EPS...

Built With Foam is your one-stop shop to bring any construction or remodeling vision to life through the power of Expanded Polystyrene (EPS), a rigid, high-density foam plastic that is completely customizable, lightweight, moisture-resistant, durable, easy-to-install, and cost-effective.

Not only is EPS perfect as a substrate for bath tile and stone, it can be used to create furniture and architectural detail for any room of the home or application at a fraction of the cost of traditional wood framing.

I’ve been using the Built with Foam shims for over 6 months now and I can honestly say that I won’t do a shower without them. For me straightening walls has always been a challenge, this system makes the process a lot simpler. I like the fact that when I’m finished I have plumb and square walls to set my tile on. Thanks Paul for designing a great product.

Built With Foam has come through for our company in a big way! We needed a huge pan and fast, Cabot answered our call in the middle of a convention and got us set up same day. It showed up quickly and fit like a glove. Perfect is what I aim for and Built With Foam helped us achieve it flawlessly!

They make it easy as can be, sent in my measurements I was contacted the next day with a few questions just to clarify I was getting exactly what I wanted and was shipped and on my doorstep within a week and fit perfectly. Very satisfied 10/10
