Built With Foam

Built With Foam is a proud US Veteran owned business based in Houston, Texas.

Our team of former contractors has a combined 90+ years of experience in the 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. Not only is custom foam cheaper as a building material, but it can cut down on labor, substantially expedite project timelines, and can remove a lot of the typical hurdles faced daily. We’ve put our experience into designing and manufacturing quality products that 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.

Wall Flattering Shims

Our wall flattering shims look great with any style of bathroom. Its easy installation and flattering designs allows you peace of mind. Go about your daily tasks without any worry of a mess or damage being done during the setting process. You don’t have to wait for the thinset to harden up before finalizing waterproofing,
allowing you to complete the installation in one smooth operation. 

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!
