Part of project
How to Install a New Bathtub and Drain Assembly · Step 2 of 9
In this video
The project begins by showcasing the prepared shower alcove. The subfloor has been made perfectly level using a self-leveling compound. The surrounding walls are open to the studs, where wood blocking has been installed to support future grab bars. A new 2-inch drain pipe is centrally located but protrudes too high above the floor.
Goal: Surface Preparation
- A perfectly level floor is critical for proper drainage and to prevent the shower pan from cracking.

FAQs
The tool list includes some unusual items. What are the truly essential tools I'll need for this bathtub installation, focusing on the specialized tasks?
Beyond basic hand tools like a tape measure and screwdriver, you'll definitely need a reciprocating saw for demolition, a level, pipe wrenches or channel locks for plumbing, a caulk gun, and a drill for securing the tub. Ignore items like bistro sets or candles from the provided list; they are not needed for this project.
This project involves demolition and plumbing. What are the most crucial safety precautions I should take throughout the process?
Always wear appropriate personal protective equipment, including eye protection, work gloves, and a dust mask, especially during demolition. Ensure the water supply is completely shut off before disconnecting any plumbing to prevent flooding. When lifting the new tub, use proper lifting techniques or get assistance to prevent back injuries.
The project is rated 'intermediate' with an estimated 24 hours. What aspects make it challenging for a DIYer, and is the time estimate realistic?
The intermediate difficulty stems from the precision required for plumbing connections, ensuring the tub is perfectly level, and potential subfloor or stud repairs. The 24-hour estimate is for active working time, not calendar days; expect to spread this project over several days or a long weekend to account for drying times and unexpected issues.
What are the most common mistakes DIYers make with the drain and overflow assembly that lead to leaks, and how can I prevent them?
The most common mistake is improper sealing. Ensure you use plumber's putty or silicone caulk correctly around the drain shoe and overflow gasket, making sure all connections are tight but not overtightened. Always perform the leak test step thoroughly before enclosing any plumbing, as undetected leaks can cause significant water damage.
