How to Unblock a Walk-In Shower Drain

Updated February 21, 2017

Clogged walk-in shower drains, although extremely annoying, are very easy to fix. Using a combination of clearing out the drain strainer cover and applying a heavy-duty drain cleaner such as Drano, your shower will be running smoothly without backing up in no time.

Remove the drain strainer from the walk-in shower drain. Peel off any clumps of hair and throw them away in a trash bag. Use a textured sponge to scrub any excess soap build-up or residue from the strainer. Set the strainer aside.

Pour the recommended amount of drain cleaner down the open drain, following the instructions on the back of the bottle. Wait at least five minutes before turning on the shower as hot as it will go. Let the hot water run through the drain, activating the drain cleaner and clearing away the clog.

Turn the water off after there is no longer any water build-up. Make sure to rinse off any excess drain cleaner on the shower floor. Reinsert the drain strainer into the drain.


If your shower takes awhile to issue hot water, you may want to consider having a bucket of hot water handy to pour down the drain before you turn the shower on to ensure the drain cleaner initially reacts to the heat.
