With the pry bar securely wedged, use it as a large handle to turn the drain fitting counter-clockwise. Apply steady force to break the old seal and threadings loose. Continue turning until the drain fitting is completely unscrewed from the drain assembly.
Goal: Bathtub Drain Unclogging (Standard)
- Once removed, you may need to tap the pry bar out of the drain fitting from the opposite side.

FAQs
What should I do if the drain key or wrench just slips, or the flange doesn't budge after applying penetrating oil?
If initial attempts fail, the flange is likely severely corroded or the putty is rock-hard. Apply more penetrating oil, like KROIL, and let it sit for several hours or even overnight to allow it to fully penetrate. If it still won't turn, your last resort is to carefully cut the flange using a rotary tool with a metal cutting wheel, making two opposing cuts without damaging the drain pipe threads.
Is it safe to cut the drain flange, and what precautions should I take?
Cutting the flange is a last resort and requires careful attention to safety. Always wear safety glasses and gloves to protect against metal fragments and sparks. Use a rotary tool with a metal cutting wheel, making two shallow, opposing cuts from the inside of the flange, being extremely careful not to cut into the drain shoe's threads below the flange.
How can I minimize the risk of damaging the bathtub or drain pipe during removal?
To prevent damage, protect the tub surface with a rag or towel if using a wrench or other tools that might slip. When cutting the flange, make shallow passes and continuously confirm you are only cutting the flange metal. Avoid excessive force, as that can warp the drain shoe or break connections further down the pipe.
Given this is a 'beginner' project, what are the most essential tools I absolutely need to have on hand?
Beyond basic safety gear, you'll definitely need a high-quality penetrating oil like KROIL, an adjustable wrench, and a specialized drain key or removal tool. For very stuck flanges, a rotary tool like the WEN 101-Piece Rotary Tool Kit with a metal cutting wheel (Stark 5 in. Metal Cut Saw Wheel) becomes essential. A putty knife and rags are also vital for preparation and cleanup.
