As a construction and home improvement specialist with years of experience in dealing with various aspects of residential and commercial construction projects, I can provide you with a detailed answer to your query about installing drywall behind a shower.

When it comes to bathroom renovations, especially in areas like showers, it's crucial to consider the materials used for both aesthetics and functionality.
Drywall is a common material used in interior walls, but it's not the best choice for areas that are frequently exposed to moisture like showers. The reason is that drywall is made from gypsum plaster pressed between two thick sheets of paper, which can absorb water and lead to mold growth and structural issues over time.

However, when you're dealing with **Fiberglass and acrylic tub and shower enclosures**, there's a specific application for drywall. These types of enclosures come with a flanged edge that is designed to attach directly to the wall studs. The flange serves as a support and a means to create a watertight seal. To hide this flange and create a smooth, finished appearance, it is indeed common practice to install drywall over it. This process involves a few steps:


1. Preparation: Before the enclosure is installed, the area behind it should be prepared. This typically means ensuring that the wall studs are in place and that any necessary electrical work is completed.


2. Enclosure Installation: The fiberglass or acrylic enclosure is then installed directly onto the bare studs. This is done to ensure a secure fit and proper support for the enclosure.


3. Flange Alignment: The flange on the enclosure is aligned with the edge of the studs, and the enclosure is secured to the studs using the appropriate fasteners.


4. Drywall Installation: Once the enclosure is securely in place, drywall can be installed over the flange. This is done to conceal the flange and provide a finished look to the enclosure.


5. Sealing: It's important to seal the seams where the drywall meets the enclosure to prevent water from seeping behind the drywall, which can lead to damage.


6. Finishing: After the drywall is installed and sealed, the final step is to finish the drywall with joint compound and paint or tile it, depending on the design preference.

It's important to note that while drywall can be used to cover the flange of a shower enclosure, it's not recommended to install drywall directly behind the enclosure where it will be exposed to water. Instead, materials that are moisture-resistant or waterproof should be used in the shower area itself. This could include materials like water-resistant drywall, cement board, or tile backer board.

In conclusion, while drywall is not typically installed directly behind a shower due to moisture concerns, it is used to cover the flange of fiberglass and acrylic enclosures to provide a finished appearance. Proper installation and sealing are key to ensuring that the area remains durable and functional.
