The Worst Materials for Bathtub and Shower Walls
When it comes to constructing the walls in a bathtub or shower, certain materials are particularly unfavorable due to their vulnerabilities to water damage, mold growth, and overall durability. Here, we will explore some of the materials that are considered the worst for these environments and why.
Why Water-Resistant Materials Matter
Choosing the right materials for your bathtub or shower walls is crucial to ensure the longevity and safety of your bathroom. Moisture from water is the primary factor leading to issues such as mold, deterioration, and warping. Therefore, using water-resistant materials is imperative.
Worst Options for Bathtub and Shower Walls
1. Drywall (Gypsum Board)
Regular drywall is not water-resistant and can absorb moisture easily, leading to mold growth, warping, and structural damage. If you must use drywall, consider moisture-resistant green board or cement board instead.
2. Wood
Untreated wood is highly prone to water damage and rot. Even treated wood can suffer in a wet environment without proper sealing and maintenance.3. Vinyl Wallpaper
While vinyl wallpaper may seem like a quick fix, it can trap moisture behind it, leading to mold and mildew growth. It is not recommended for areas where moisture is present.
4. Particle Board
Similar to regular wood, particle board is not designed for wet environments and can swell, warp, and deteriorate when exposed to moisture.
5. Standard Plaster
Like drywall, standard plaster is not water-resistant and can crumble or mold when exposed to high humidity levels.
6. Painted Surfaces
Standard interior paint is not designed for wet environments and can peel off or attract mold if not specially formulated for such areas.
Common Mistakes and Their Consequences
Personal Experience: Failed Drywall Installation
During my adolescent years, a shower had drywall installed with nothing else over it, and it wasn't even the moisture-resistant green board. My mother, patiently waiting for my father (a world-class procrastinator), finally decided to paint the area. We began to use it until a few years later, when my father had to cut out and properly finish the bottom 8 inches of drywall. This experience emphasizes the importance of proper materials and finishing techniques.
Case Study: The Horrifying Results
In an extreme case, I witnessed a house with regular gypsum board painted with gloss paint for both shower and bath enclosures. Needless to say, it didn’t work, and the house was full of mold. This underscores the critical need for water-resistant materials to prevent such issues.
Other materials, such as cardboard and plastic sheathing, would likely be even worse options in such environments.
Best Practices for Choosing Materials
For a shower or bathtub area, it is best to use water-resistant materials like tile, fiberglass, or acrylic panels. These materials are specifically designed to withstand moisture and prevent mold growth, ensuring a safer and longer-lasting bathroom experience.
