Bath Tub To Shower Conversion Kit

A bath tub to shower conversion kit typically includes a pre-fabricated shower pan and wall surrounds, but a custom tile conversion requires specific wet-area waterproofing, substrate prep, and layout planning. For homeowners in Franklin, TN, moving from an old tub to a walk-in shower is a major upgrade. While off-the-shelf kits exist, a custom tile approach ensures the new shower fits your space perfectly without relying on standard acrylic dimensions. We handle custom bathroom remodels that focus on proper moisture protection and artisan tile installation, ensuring your daily routine is supported by a durable, watertight foundation.
Understanding the Custom Shower Process

When you remove a bathtub, the exposed framing and plumbing rarely align perfectly with a standard conversion kit. A custom tile shower installation adapts to the actual conditions of your bathroom. First, we assess the exposed wall studs and floor joists. Hidden structural rot behind old tile or a squishy shower floor often requires immediate repair before any new materials go in. Next comes the substrate prep and wet-area waterproofing. We build custom shower pans that slope correctly to the drain, ensuring water flows away efficiently. This step is critical because a shower pan failure leads to costly leaks.
Material selection plays a huge role in the final result. Instead of settling for a plastic surround, you choose the exact tile, grout, and layout that fits your home. Oleksiy personally executes every project, bringing over 20 years of tile and stone experience to your Franklin home. We make sure the transition from your bathroom floor to the new shower pan is smooth, level, and built to last. If you are planning a full bath tub to shower conversion, understanding this prep work is the first step.
Key Decisions for Your Shower Remodel

Moving forward with a shower remodel requires several practical choices. Here are the main decision points for your project:
- Material selection: Ceramic and porcelain tiles offer different durability levels. Porcelain is denser and absorbs less water, making it ideal for wet areas.
- Shower pan prep: You can choose a curbed entry or a curbless walk-in shower. Curbless requires modifying the floor joists to achieve the correct slope without a step.
- Waterproofing system: We use TCNA-standard membrane systems to protect your walls and subfloor from moisture.
- Layout planning: Consider where you want niches, benches, and fixtures. Moving plumbing from the tub drain to a center shower drain adds time to the project.
- Cost factors: The final price depends on an on-site inspection. Tile price, pattern complexity, and the substrate condition discovered after demolition all drive the cost. There is no fixed online price because every bathroom is different.

Mistakes to Avoid During Demolition and Prep

Homeowners often encounter issues when they rush the demolition or overlook hidden damage. One major mistake is ignoring a bouncy floor under the old tub. If the subfloor flexes, the new tile and grout will eventually crack. We always check the floor structure before laying backerboard. Another frequent error is relying on water-resistant drywall instead of proper wet-area waterproofing. A custom shower requires a dedicated membrane system to prevent mold and mildew inside the walls.
Poor layout planning can lead to awkward tile cuts and lippage, where tile edges stick up and create a toe-stubbing hazard. Every tile must be set with purpose, ensuring symmetry and a level finish. We take the time to map out the grout joints before mixing any thin-set mortar. Skipping this step often results in a sloppy appearance that detracts from the entire bathroom remodel. If you are updating other areas, similar care applies to tile walls & backsplashes.
When to Call a Tile Professional
Converting a tub to a walk-in shower involves plumbing modifications, structural checks, and precise tile alignment. You should call a professional when you need to move the drain location or update old water supply lines. Building a custom shower pan that slopes perfectly to the drain is a complex task that requires hands-on experience. If you discover a leaking shower valve or structural rot behind the old tub, a professional assessment is necessary to ensure your home remains safe and dry.
Oleksiy handles the entire tile installation process, from the initial estimate preparation checklist to the final grout joint. We keep the work area clean, protect your home, and communicate clearly throughout the project. While some homeowners consider acrylic shower installers for a quick fix, a custom tile shower offers superior durability and design flexibility.

Maintaining Your New Custom Shower
Keeping your new custom tile shower looking pristine requires simple, consistent care. After the thin-set mortar and grout fully cure, we recommend using a squeegee on the tile walls after every shower. This quick habit prevents hard water buildup and soap scum from settling into the grout joints. Avoid harsh, abrasive chemical cleaners that can degrade the wet-area waterproofing or strip the sealer from natural stone.
Instead, use a pH-neutral tile cleaner and a soft sponge for weekly maintenance. If you notice any changes in the grout lines or caulking around the shower pan over the years, address them promptly to maintain the integrity of the moisture barrier. Proper maintenance ensures your artisan tile installation remains a beautiful, functional centerpiece in your Franklin home for decades.
