Bathtub Drain Clogged or Not Draining

Common Symptoms

• Bathtub fills with water that does not drain during use
• Bathtub takes 10+ minutes to drain completely after use
• Water remains standing in the tub after exiting
• Gurgling or bubbling sound from the bathtub drain
• Faint sewage or musty smell coming from the tub drain
• Visible hair accumulation around or under the drain stopper

Most Likely Causes

1. 1

   Hair and Soap Scum on the Drain Stopper (Most Common)

   Bathtub drain stoppers — whether trip-lever, lift-and-turn, push-pull, or toe-touch designs — have surfaces on their underside that catch hair. The stopper sits in the drain opening and every bath deposits hair around its base and on its shaft or strainer crossbars. Soap scum binds the hair into a solid plug. Removing the stopper and clearing the attached hair resolves the majority of bathtub clogs without any further disassembly.

2. 2

   Hair Clog in the Drain Body Below the Stopper

   Even after cleaning the stopper, a secondary hair accumulation often exists in the drain body 2–8 inches below the stopper seat. This section of the drain has a crossbar or basket that catches hair escaping the stopper. A Zip-It drain cleaning tool inserted after stopper removal reaches this zone and pulls the hair out effectively.

3. 3

   Trip-Lever Linkage or Rocker Arm Jamming the Stopper Closed

   Trip-lever drain assemblies use a plunger or rocker arm linkage inside the overflow tube (the plate on the tub wall above the drain) that mechanically blocks the drain when hair or debris wraps around the linkage rod. In this case, the drain is not clogged — the mechanical stopper is stuck in the closed position. Adjusting or cleaning the trip-lever linkage through the overflow plate resolves this type of 'clog.'

4. 4

   P-Trap Accumulation

   In bathtubs used very frequently or not maintained for years, hair and soap scum can accumulate past the drain body and into the P-trap. P-trap clogs in tubs are less common than stopper clogs but occur in older homes or after a long period of neglect. A drain snake is required to reach the P-trap in a bathtub — the trap is typically under the bathroom floor and not directly accessible through the drain opening without a long snake.

Quick DIY Checks

1. 1Step 1 — identify your stopper type: before removing anything, identify what type of drain stopper your tub has. (a) Lift-and-turn: has a small knob on top — turn counterclockwise while lifting to unscrew and remove. (b) Push-pull: a post with no visible screw — pull straight up firmly, then unscrew the center post from the base with pliers if needed. (c) Toe-touch: push down to toggle open/close — unscrew the whole cap counterclockwise. (d) Trip-lever: an overflow plate on the tub wall above the drain with a lever — the stopper is controlled by a plunger inside the overflow tube; skip to Step 4 for this type. (e) Simple strainer: no stopper, just a strainer over the drain — proceed to Step 2.
2. 2Step 2 — remove the stopper and clean it: remove the stopper per its type (Step 1). Once removed, inspect the underside and base — you will almost always find a hair mat wound around the shaft and caked with soap scum. Grip the hair with paper towels and pull the entire mat off. Rinse the stopper under hot running water and scrub the underside with an old toothbrush. Inspect the drain opening where the stopper was seated — if you see more hair packed on the drain crossbars, proceed to Step 3.
3. 3Step 3 — Zip-It tool and drain body cleaning: with the stopper removed, insert the Zip-It drain cleaning tool (or a hand-bent wire coat hanger with a small hook bent at the end) into the drain opening. Push it down 8–12 inches, rotate to engage any hair below the crossbars, and pull out. Repeat 3–4 times until no more hair comes out. Shine a flashlight into the drain body to verify it is clear. Flush with a kettle of hot water to dissolve soap scum on the pipe walls.
