Removal of Old Pan: Carefully remove existing shower pan, taking note of plumbing connections

Begin by shutting off the water supply to the RV's shower system to prevent any accidental spills or flooding during the removal process. Locate the access panel or hatch that covers the shower pan's plumbing connections. This is typically found beneath the shower area or in a nearby cabinet. Remove any screws or fasteners securing the panel and set them aside for later use.

With the access panel removed, carefully inspect the plumbing connections attached to the old shower pan. Take note of the type and size of the pipes, as well as the fittings and seals used. It's crucial to ensure that these connections are properly sealed to prevent leaks once the new pan is installed. If necessary, take photographs or make sketches of the connections for reference later.

Next, remove any remaining fixtures or fittings attached to the old shower pan, such as the showerhead, faucet, or drain. This may require the use of specialized tools or solvents to loosen stubborn components. Be cautious not to damage the surrounding areas or the plumbing connections while removing these fixtures.

Once all fixtures and fittings have been removed, carefully lift the old shower pan out of place. It may be helpful to have a second person assist with this step, as the pan can be heavy and awkward to handle. Take care not to disturb the plumbing connections or damage the surrounding areas as you remove the pan.

Inspect the area where the old pan was installed for any signs of damage, mold, or mildew. If any issues are found, address them before proceeding with the installation of the new shower pan. This may involve repairing or replacing damaged components, cleaning and treating mold or mildew, or applying a waterproofing sealant to protect against future water damage.

Measuring and Cutting: Measure space for new pan, cut to fit if necessary, ensuring proper drainage

Begin by measuring the space where the new shower pan will be installed. Use a tape measure to get the dimensions of the area, taking note of any obstructions or irregularities that may affect the fit of the pan. It's crucial to measure twice to ensure accuracy, as even a small error can lead to significant problems during installation.

Once you have the measurements, transfer them to the new shower pan. If the pan needs to be cut to fit, use a utility knife or a specialized cutting tool designed for the material of the pan. When cutting, be sure to wear appropriate safety gear, such as gloves and safety glasses, to protect yourself from injury.

After cutting the pan to size, inspect the edges to ensure they are smooth and free of any sharp or jagged edges that could cause leaks or damage to the surrounding area. If necessary, use a file or sandpaper to smooth out any rough edges.

Proper drainage is essential for the shower pan to function correctly. Check that the drain hole is properly aligned with the RV's existing plumbing and that there are no obstructions that could impede water flow. If the drain hole needs to be adjusted, use a drill to carefully enlarge or reposition it as needed.

Before installing the pan, apply a layer of sealant around the edges to create a watertight seal. This will help prevent leaks and ensure that water drains properly. Once the sealant is in place, carefully position the pan in the designated area, ensuring that it is level and secure.

Finally, test the shower pan by running water through it to check for any leaks or drainage issues. If everything is functioning properly, you can proceed with the final installation steps, such as connecting the plumbing and securing the pan in place.
