Why Convert to Schluter or Kerdi?
Before we dive into the how-to, let's talk about why you should consider converting your rubber liner shower to a Schluter or Kerdi system. Rubber liners, while a traditional waterproofing method, have some drawbacks. Over time, they can become brittle, crack, and leak, leading to water damage behind your shower walls. Schluter and Kerdi systems, on the other hand, offer a more advanced and reliable solution. These systems utilize a surface waterproofing membrane, typically made of a modified polyethylene sheet, that is bonded directly to the shower's substrate. This creates a seamless, watertight barrier that prevents water from penetrating the structure behind your tile. One of the major advantages of Schluter and Kerdi is their integrated system approach. They offer a range of components, including shower pans, drains, curbs, and sealing strips, that are designed to work together seamlessly. This ensures a consistent level of waterproofing throughout the entire shower enclosure. Think of it like this: rubber liners are like a raincoat with potential holes, while Schluter and Kerdi are like a fully sealed drysuit. Which one would you trust more to keep you dry? Beyond waterproofing, Schluter and Kerdi systems offer other benefits, such as ease of installation (especially for DIYers) and long-term durability. They are also resistant to mold and mildew growth, which is a common problem in shower environments. Furthermore, these systems allow for greater design flexibility, as they can be used with a wide variety of tile types and sizes. The upfront cost of a Schluter or Kerdi system may be higher than a traditional rubber liner, but the long-term benefits, including reduced risk of water damage and a more durable shower, make it a worthwhile investment. Plus, the peace of mind knowing your shower is protected by a top-of-the-line waterproofing system is priceless. So, if you're looking for a reliable, long-lasting, and aesthetically pleasing shower solution, converting to a Schluter or Kerdi system is definitely worth considering.
Assessing Your Current Shower Setup
Okay, guys, before you start swinging that sledgehammer, it's crucial to assess your current shower setup. This step is vital for planning your conversion and ensuring you have a smooth installation process. The first thing you'll want to do is carefully inspect your existing shower for any signs of water damage. This includes looking for discoloration, staining, or soft spots on the walls and floor surrounding the shower. Check the grout lines for cracks or missing pieces, as these can be entry points for water. Also, pay close attention to the area around the drain and any penetrations in the shower walls, such as showerheads or faucets. If you find any significant water damage, it's essential to address it before installing the new Schluter or Kerdi system. This might involve repairing or replacing damaged studs, subflooring, or drywall. Ignoring water damage can compromise the integrity of your new shower and lead to future problems. Next, you'll need to determine the size and layout of your shower. Measure the width, depth, and height of the shower enclosure, and note the location of the drain. This information will help you choose the appropriate size of Schluter or Kerdi shower pan and other components. Consider the existing plumbing and electrical fixtures in your shower. You might need to make adjustments to these during the conversion process, so it's important to factor them into your plan. For example, you might need to relocate the showerhead or install a new mixing valve. Finally, take some time to think about the design of your new shower. Do you want to keep the same layout, or are you considering making changes? What type of tile do you want to use? These decisions will influence the components you need to purchase and the installation process. By thoroughly assessing your current shower setup, you'll be well-prepared to tackle the conversion and create the shower of your dreams.

A sledgehammer, pry bar, and utility knife will be your best friends for removing the old tile, mortar bed, and rubber liner. Wear safety glasses and gloves to protect yourself from flying debris. You'll also need a dust mask to avoid inhaling harmful particles. Once you've demoed the shower, you'll need tools for preparing the substrate. A concrete grinder or scarifier will help smooth out the surface and remove any remaining mortar or adhesive. A level is crucial for ensuring your shower pan and walls are plumb and level. For installing the Schluter or Kerdi system, you'll need a notched trowel, mixing buckets, a margin trowel, and a sponge. The notched trowel is used to apply the thin-set mortar that bonds the membrane and tiles to the substrate. Make sure you choose the correct notch size recommended by the manufacturer. You'll also need a Schluter or Kerdi sealing compound, such as Kerdi-Fix or Schluter-S, to seal seams and penetrations. Of course, you'll need the Schluter or Kerdi system components themselves, including the shower pan, membrane, drain, and any other accessories you need for your specific shower design. Make sure you purchase the correct sizes and quantities of each component. Finally, you'll need tile, thin-set mortar, grout, and tile spacers for finishing the shower. Choose a tile that is suitable for wet environments and follow the manufacturer's recommendations for installation. Don't forget to factor in safety gear! Always wear safety glasses, gloves, and a dust mask when working with power tools or handling materials that can irritate your skin or lungs. By gathering all the necessary tools and materials before you start, you'll set yourself up for a successful and stress-free shower conversion.
Step-by-Step Guide to Converting Your Shower
Alright, let's get down to the nitty-gritty. This is the step-by-step guide to converting your shower to a Schluter or Kerdi system. Take your time, follow the instructions carefully, and don't be afraid to ask for help if you get stuck. Remember, patience is key!
Step 1: Demolition
The first step is to demolish your existing shower. This can be the most physically demanding part of the project, but it's also the most satisfying! Start by removing the shower door or curtain. Then, use a utility knife to score the grout lines around the tiles. This will help prevent chipping and make the tiles easier to remove. Next, use a sledgehammer and pry bar to remove the tiles.
