Install New Drain and Overflow Assembly — Disconnect Waste and Overflow Assembly
Part of project
How to Remove an Old Bathtub for a Bathroom Remodel · Step 4 of 7
In this video
Assemble the new bath waste and overflow drain kit. From inside the tub, insert the stopper linkage into the overflow opening while holding the overflow pipe assembly against the back of the tub. Secure the overflow faceplate with screws. From below, attach the bath tee to the overflow pipe and then connect the bath shoe to the tee, ensuring proper alignment with the drain hole. Use gaskets at all connection points. Finally, install the P-trap and connect the entire assembly to the main drain line in the floor.
Goal: Plumbing
- Ensure all gaskets are properly seated to prevent leaks. Hand-tighten connections first, then give a final quarter-turn with a wrench if needed, being careful not to over-tighten plastic fittings.

FAQs
What are the most critical safety precautions I should take before and during bathtub removal?
Always shut off the main water supply to your home and drain the lines before beginning. Wear safety glasses (HDX Indoor Safety Glasses), heavy-duty gloves (Husky Large Heavy Duty Glove), and a respirator (3M P100 Household Respirator) to protect against dust, debris, and potential mold. Ensure the work area is well-ventilated, and if using power tools, keep cords away from water and work carefully.
Do I really need specialized tools like a tub drain wrench or a reciprocating saw, or can I get by with standard tools?
A tub drain wrench (like the Husky Double Ended Tub Drain Wrench) is highly recommended for efficiently removing the drain assembly without damaging the plumbing. While not always strictly necessary, a reciprocating saw with a demolition blade (like DIABLO Demo Demon) can significantly ease the removal of difficult tubs, especially heavy cast iron ones, by cutting them into manageable pieces. A pry bar (Stanley 12 in. Wonder Bar Pry Bar) is also essential for detaching the tub.
How long does a typical bathtub removal project take for an intermediate DIYer, and is it a one-person job?
For an intermediate DIYer, removing a bathtub typically takes 4-8 hours, depending on the tub type, access to plumbing, and unexpected issues. While some initial steps can be done solo, extracting the tub itself, especially if it's cast iron, often requires at least two people due to its weight and bulk to prevent injury or damage.
What are common pitfalls or mistakes to avoid when disconnecting plumbing or detaching the tub from the wall?
A common mistake is not completely shutting off the water or checking for remaining pressure before disconnecting pipes, leading to leaks. Another is forcefully prying without locating all securing points (like nailing flanges behind the surround), which can damage surrounding walls or the subfloor. Always double-check for hidden screws or mortar that might still be holding the tub in place.
