How to Replace a Bathtub Drain Flange · Step 1 of 7
In this video
Carefully lift and lower the bathtub into position, aligning the lubricated tailpiece with the floor drain. Guide the tailpiece straight down into the drain flange until the tub rests firmly and level on the floor. Once in place, fill the tub with a few inches of water to test for leaks. After confirming there are no leaks, apply a continuous bead of 100% silicone caulk around the entire base of the tub to create a watertight seal against the floor.
Goal: Position the tub, connect the drain, and seal the base
- Have a helper when lifting and moving the tub to avoid injury or damage to the tub or floor.

FAQs
What if my old drain flange is severely corroded or stuck and won't unscrew?
If the old flange is stubborn, try applying penetrating oil and letting it soak for a while to help loosen rust. The specialized Husky Tub Drain Removal Tool is designed for maximum grip, but for extreme cases, you might need to carefully cut the crossbars from the inside with a reciprocating saw to collapse the flange and remove it.
Do I have to use plumber's putty, or can I use silicone sealant for the new flange?
While the guide suggests plumber's putty, clear silicone sealant like DAP Silicone Max is an excellent alternative for a more permanent, waterproof seal that resists degradation over time. Ensure the tub surface is completely dry and clean before applying silicone, as it requires a perfectly dry surface to cure properly. Plumber's putty is generally easier for beginners to work with and remove if necessary.
How can I ensure a watertight seal and prevent future leaks after installing the new flange?
To ensure a watertight seal, apply an even, generous bead of plumber's putty or silicone around the underside lip of the new flange before inserting it into the drain opening. When tightening the flange, make sure it's snug, but avoid over-tightening which can distort the seal or even crack the tub. Always conduct the leak test by filling the tub and watching the drain connection underneath for at least 15-30 minutes.
Is the specified "Husky Tub Drain Removal Tool" essential, or are there alternatives if I don't have it?
The Husky Tub Drain Removal Tool is highly recommended for this project as it provides the best leverage and reduces the risk of damaging the drain. While some people attempt to use pliers with a rag or a screwdriver across the crossbars, these methods can easily strip the drain or not provide enough torque. Investing in the correct tool is crucial for a successful, frustration-free installation.
