Upgrading a bathroom can be a daunting task, especially when dealing with heavy tiles and messy grout. FlexStone bath wall surrounds have become a popular choice for homeowners seeking a beautiful, stone-like finish without the weight or maintenance of traditional materials. This guide provides a comprehensive look at what these products are, how to prepare for your project, and the step-by-step process for a successful installation.
FlexStone is a high-quality composite material that offers the aesthetic appeal of natural stone with the durability of modern polymers. It is designed to be completely waterproof and resistant to mold and mildew, making it an ideal choice for wet environments like showers and tub alcoves. By following a clear set of instructions, even a DIY enthusiast can achieve a professional-looking result in a fraction of the time it takes to install tile.
Why Choose FlexStone for Your Bathroom?
Before diving into the installation process, it is helpful to understand the benefits of this material. FlexStone is lightweight, which makes it much easier to handle than real stone slabs or large-format tiles. It is also flexible enough to handle walls that might not be perfectly plumb, which is a common issue in older homes.
Another significant advantage is the lack of grout lines. Because the panels are large and seamless, there are no porous areas for mold to grow or for water to seep through. This creates a low-maintenance surface that only requires a quick wipe-down with mild soap to stay clean. Additionally, the material is UV-resistant, meaning the colors and patterns will not fade over time even if your bathroom has a large window.
Essential Tools and Materials
To ensure a smooth installation, you should gather all necessary tools and materials before you begin. Having everything on hand prevents mid-project delays and helps you focus on precision. You will typically need the following items:
- Measuring Tape: For accurate dimensions of your shower or tub area.
- Circular Saw or Jigsaw: Equipped with a fine-tooth blade for cutting the panels.
- Caulk Gun: To apply the adhesive and the final silicone sealant.
- Level: To ensure all panels and trim pieces are perfectly straight.
- Drill and Hole Saw: For creating openings for the showerhead and mixing valve.
- Construction Adhesive: Specifically recommended for composite wall panels.
- 100% Silicone Sealant: In a color that matches your chosen FlexStone finish.
- Painter’s Tape: To hold panels in place while the adhesive sets.
Choosing the Right Adhesive
Not all adhesives are created equal. It is critical to use a high-quality, non-solvent-based construction adhesive that is compatible with both your wall substrate and the composite material. Solvent-based adhesives can sometimes damage the backing of the panels or cause warping over time. Always check the manufacturer’s recommendations for the best bond.
Preparing Your Bathroom Walls
The secret to a long-lasting wall surround is proper preparation. FlexStone can be installed over several different surfaces, including moisture-resistant drywall (greenboard), cement backer board, or even existing tile if it is clean and firmly attached. However, the surface must be flat, dry, and free of dust or oils.
If you are removing old tile, ensure that any remaining adhesive is scraped away. If the underlying wall is damaged or showing signs of rot, it is best to replace it with new moisture-resistant drywall before proceeding. Once the walls are ready, take detailed measurements of the height and width of each wall. Remember to account for the thickness of the panels when measuring the side walls.
Measuring and Cutting the Panels
Accuracy is vital during the cutting phase. Start by measuring the back wall first, as this is typically the largest panel. Mark your measurements on the front side of the panel using a pencil or a fine-tip marker. It is often helpful to apply a layer of painter’s tape over the cutting line to prevent any chipping of the finished surface.
Making Precise Cuts
When using a circular saw, cut from the back side of the panel to ensure a clean edge on the finished side. For smaller cutouts, such as the holes for the plumbing fixtures, a hole saw or a jigsaw is the best tool. Measure the distance from the corner and the floor to the center of your mixing valve and showerhead pipes. Double-check these measurements before you drill.
The Importance of Dry Fitting
Never apply adhesive until you have performed a “dry fit.” Place the panels against the wall to ensure they fit snugly and that all plumbing holes align perfectly. This is the time to trim off any excess material or sand down edges for a tighter fit. Once you are satisfied with how the panels sit, you can move on to the permanent installation.
The Installation Process Step-by-Step
Once your panels are cut and dry-fitted, you are ready to begin the permanent installation. Follow these steps for the best results:
- Clean the Surfaces: Wipe down the back of the panels and the wall with a damp cloth to remove any dust. Let them dry completely.
- Apply Adhesive: Use your caulk gun to apply beads of adhesive to the back of the panel. A common pattern is a series of vertical lines spaced about 6 inches apart, with a perimeter bead around the edges.
- Set the Back Panel: Press the back panel firmly against the wall. Use a laminate roller or your hands to apply even pressure across the entire surface to ensure a strong bond.
- Install Side Panels: Repeat the process for the side panels. Ensure the corners where the panels meet are tight.
- Apply Trim Pieces: FlexStone kits usually come with corner moldings and edge trim. Apply a small bead of adhesive to these pieces and press them into place to hide the cut edges and provide a finished look.
- Secure with Tape: Use painter’s tape to hold the panels and trim in place for at least 24 hours while the adhesive cures.
Sealing for Water Tightness
The final and most important step is sealing the joints. Even though the panels are waterproof, water can still seep behind them through the corners or the bottom edge if they are not properly caulked. Use 100% silicone sealant for this task.
Apply a consistent bead of silicone along all vertical corners, the bottom edge where the panels meet the tub or shower base, and around the plumbing fixtures. Smooth the bead with a caulking tool or a gloved finger dipped in soapy water for a clean, professional finish. Allow the silicone to cure for at least 24 hours before using the shower.
Maintenance Tips for Longevity
To keep your new wall surround looking new, avoid using abrasive cleaners or scouring pads, which can scratch the surface. Instead, use a soft cloth or sponge with a mild household cleaner. If you live in an area with hard water, using a squeegee after each shower can prevent mineral buildup and keep the finish shining. Because there is no grout, you will never have to worry about scrubbing away stains or resealing porous lines.
Conclusion
Installing a FlexStone bath wall surround is an excellent way to refresh your bathroom with a high-end look that is both durable and easy to maintain. By taking the time to measure accurately, dry-fit your panels, and seal the joints properly, you can create a waterproof sanctuary that will last for years.
