A shower drain opened on tile floor with a drain snake and hand tool beside it

Shower clogs are almost always hair bound with soap residue sitting just below the strainer. Remove the strainer and clear what you can reach by hand or with a hair removal tool, then use a small drain snake through the opening. Skip chemical drain cleaner, and call a plumber if the water backs up into other fixtures or the clog returns quickly.

Key points

Most shower clogs sit within the first foot of pipe.
Chemical cleaner sits on a hair mat and attacks the pipe instead.
Several slow fixtures at once means the problem is past the shower.

Step by step

Remove the strainer, which usually lifts out or comes off with one screw
Pull the visible hair mat with gloves or a barbed plastic hair tool
Flush with hot water and see whether flow returns
If not, work a small hand snake in and rotate rather than force it
Reassemble the strainer and run water for a full minute to confirm

Why not chemical drain cleaner

Caustic cleaners are designed for organic sludge, not a compacted hair mat. The liquid usually pools above the clog, generating heat against the pipe and joints instead of dissolving the blockage.

It also creates a hazard for the next person who opens the drain, including a plumber. If the clog persists after mechanical attempts, tell whoever comes out whether any chemical went down.

When it is not the shower

Water rising in the tub when the washing machine drains
A toilet that gurgles when the shower runs
Two or more fixtures draining slowly at the same time
A clog that returns within days of being cleared
Any sewage odor at the drain

Backing up in more than one fixture?

Keeping it clear

A hair catcher over the drain solves most of this permanently and costs almost nothing. Rinse it after each shower rather than letting it dry into a mat.

Once a month, run hot water for a few minutes to move soap residue along the line. Skip the habit of pouring grease or heavy cleaners down any drain.
