Replacing Your RV Tub with a Shower: A Comprehensive Guide

If you're tired of the cramped and outdated bathtub in your RV and yearning for a more spacious and modern shower, you're not alone. Many RV owners opt to replace their tub with a shower to create a more functional and comfortable bathroom space. This guide will walk you through the process of how to replace an RV tub with a shower, ensuring a successful and safe renovation.

Planning Your RV Shower Conversion

Before you start any work, it's crucial to plan your new shower space. Consider the following aspects:

• Size and Layout: Measure your current tub and bathroom space to ensure your new shower will fit and function well.
• Shower Type: Choose between a standard shower pan, a custom tile shower, or a shower insert. Each has its pros and cons, so consider your budget, time, and skill level.
• Ventilation: Proper ventilation is essential to prevent mold and mildew. Plan to install a vent fan if your RV doesn't have one.
• Waterproofing: Ensure your new shower is well-sealed and waterproof to protect your RV's interior.

Gathering Tools and Materials

Before you begin, gather the necessary tools and materials. Here's a list to help you get started:

• Circular saw or jigsaw
• Drill and driver bits
• Tape measure
• Level
• Utility knife
• Safety glasses
• Work gloves
• Shower pan or insert
• Cement backer board
• Thinset mortar
• Tile (if applicable)
• Tile adhesive
• Grout
• Silicone caulk
• Waterproof membrane
• Vent fan (if needed)

Removing the Old Tub

With your planning and preparation complete, it's time to remove the old tub. Here's how:

1. Turn off the water supply to the tub and drain the lines.
2. Remove the tub's faucet and drain assembly.
3. Use a utility knife to cut through any caulk or sealant around the tub.
4. Drill holes in the tub's bottom to create leverage points for removal.
5. Carefully pry the tub out of its space using a pry bar or screwdriver. You may need to break it into smaller pieces for easier removal.

Installing the New Shower

Now that the old tub is gone, it's time to install your new shower. Follow these steps:

1. Prepare the Area: Clean the space and ensure it's level. If needed, use shims to create a level base for your shower pan or insert.
2. Install the Shower Pan or Insert: Follow the manufacturer's instructions to install your shower pan or insert. Ensure it's level and properly supported.
3. Waterproof the Shower: Apply a waterproof membrane to the walls and floor of the shower area to prevent water damage.
4. Install the Shower Walls (if tiling): Cut cement backer board to fit the shower walls, securing it in place with thinset mortar. Allow the mortar to cure before proceeding.
5. Tile the Shower (if applicable): Spread tile adhesive on the shower walls and apply tiles, following a level and straight layout. Allow the adhesive to cure before grouting.
6. Grout the Shower: Mix and apply grout to the tile joints, following the manufacturer's instructions. Allow the grout to cure before sealing.
7. Install the Shower Faucet and Drain: Install the new faucet and drain assembly, ensuring they're properly sealed and secured.
8. Install a Vent Fan (if needed): Cut a hole in the RV's roof or wall for the vent fan, following the manufacturer's instructions. Install the fan and ensure it's properly vented to the outside.

Testing Your New Shower

Before using your new shower, test it to ensure everything is working correctly:

• Turn on the water supply and test the faucet to ensure it's functioning properly.
• Run water in the shower to check for leaks and ensure the drain is working correctly.
• Test the vent fan to ensure it's properly ventilating the shower area.

Congratulations! You've successfully replaced your RV tub with a shower. With proper planning, the right tools, and careful execution, you can enjoy a more comfortable and functional bathroom space in your RV. Happy travels!
