If you want to address the issue of slippery bathroom floor tiles without changing them, there are a few cheaper solutions you can consider:
Non-slip mats or rugs: Place non-slip mats or rugs on the bathroom floor near the shower, bathtub, and sink areas. These mats typically have a rubberized or textured bottom that provides better traction and reduces the risk of slipping.
Non-slip adhesive strips: Apply non-slip adhesive strips directly onto the tiles. These strips have a gritty surface that enhances grip and helps prevent slipping. You can place them strategically in areas where slips are more likely to occur, such as near the shower or bathtub.
Anti-slip coatings: Use anti-slip coatings or treatments designed for bathroom tiles. These coatings can be applied to the existing tiles to increase their slip resistance. They create a textured surface that improves traction and reduces the risk of accidents.
Silicone caulking: Apply a thin bead of clear silicone caulking in the areas where you commonly step, such as near the shower or bathtub. The silicone caulking creates a slightly textured surface that can enhance traction.
Rubberized grip pads: Consider using rubberized grip pads or adhesive treads designed for improving traction on slippery surfaces. These pads adhere to the bottom of your feet and provide extra grip when walking on the tiles.
Remember, while these solutions can help improve the slip resistance of your bathroom floor, it's still essential to practice caution and take additional safety measures like using handrails, installing grab bars, and keeping the floor dry to prevent accidents.
