At Reliable Design-Build-Remodel, we understand that one of the most important considerations for any bathroom remodel in Birmingham, AL is choosing flooring that can withstand moisture. Bathrooms are high-humidity environments, and without the proper flooring, you risk damage, mold, and unnecessary stress. In this blog, we’ll answer common questions about waterproof bathroom flooring to help you make the best decision for your home.

What is the best waterproof flooring for bathrooms?
When it comes to selecting the best waterproof flooring for bathrooms, luxury vinyl tile (LVT), porcelain tile, and natural stone are among the top contenders. Each option offers its own unique blend of durability, aesthetics, and water resistance. However, luxury vinyl tile has surged in popularity for its affordability, ease of installation, and realistic look that mimics wood or stone. Porcelain tile remains a classic choice due to its density and complete water resistance, making it ideal for both floors and shower walls. Natural stone, like slate or marble, is naturally resistant to water but does require sealing to prevent absorption and staining. At Reliable Design-Build-Remodel, we often recommend LVT for clients who want the perfect blend of style, function, and budget-friendliness.
Can waterproof vinyl plank flooring be used in bathrooms?
Yes, waterproof vinyl plank flooring is a fantastic option for bathrooms. It is specifically engineered to resist moisture, spills, and humidity—making it highly suitable for wet areas. Unlike traditional hardwood, which can warp or swell when exposed to water, vinyl plank maintains its structure while offering the warm, wood-like appearance many homeowners love. This material is also comfortable underfoot and can often be installed as a floating floor over existing surfaces. Our team frequently installs vinyl plank flooring in Birmingham bathrooms due to its quick installation process and its remarkable durability in high-traffic areas.
Can mold grow under vinyl plank flooring?
While vinyl plank flooring itself is waterproof, mold can still grow underneath it if water seeps beneath the surface and becomes trapped. This usually happens when the subfloor is not properly prepared or if the seams are not sealed adequately. Moisture from spills, leaks, or even high humidity can find its way under the planks and linger, creating an environment ripe for mold growth. To prevent this, it’s essential to install a proper moisture barrier and ensure the subfloor is dry before laying vinyl plank. At Reliable Design-Build-Remodel, we go the extra mile by inspecting subfloors and recommending additional protection where needed, so you can enjoy a mold-free, waterproof space.

What flooring is 100% waterproof?
There are only a few flooring types that can truly be classified as 100% waterproof, and those include porcelain tile, ceramic tile, and sheet vinyl. These materials are impervious to water and are commonly used in commercial bathrooms and high-moisture areas. Porcelain tile, in particular, is denser and less porous than ceramic, making it ideal for complete waterproofing. Sheet vinyl offers a seamless installation, which prevents water from penetrating through gaps or seams. While LVT and waterproof laminate are water-resistant, they may not be fully waterproof if not installed correctly. Our team at Reliable Design-Build-Remodel can help assess your specific needs and guide you toward the truly waterproof options that will best serve your lifestyle.
How to waterproof your bathroom floor?
Waterproofing your bathroom floor involves more than just choosing the right flooring—it also means installing it correctly and applying preventative measures. The process typically starts with preparing the subfloor to be clean, level, and dry. Next, a waterproof membrane or underlayment may be applied, especially in high-moisture areas like shower surrounds and under tubs. For tile floors, a waterproof grout or sealer should be used to close up pores and cracks where water can seep through. Proper caulking around the edges and fixtures further enhances water protection. At Reliable Design-Build-Remodel, we follow a detailed step-by-step approach to waterproofing, ensuring your bathroom remains dry and structurally sound for years to come.
Which is better, waterproof laminate or waterproof vinyl?
While both waterproof laminate and waterproof vinyl are engineered to resist moisture, waterproof vinyl generally comes out ahead—especially in bathroom applications. Vinyl is composed of synthetic materials that are inherently water-resistant and less prone to damage from prolonged exposure to moisture. It is also softer underfoot, more flexible in terms of installation, and better at mimicking natural textures like wood or stone. Waterproof laminate, on the other hand, often has a wood-based core, which can swell or degrade if not completely sealed. In our experience working on Birmingham homes, vinyl tends to provide longer-lasting performance in bathrooms, especially in households with children or pets. That said, both options of waterproof bathroom flooring can work well depending on the style, budget, and maintenance preferences of the homeowner.
