If you notice an odour in your bathroom, it may be coming from your shower drain. Your shower is where you go to get clean, so a foul odour coming from the drain is quite unpleasant. Shower drain odour is often the result of a clogged drain or stagnant water. Whatever the cause, you likely want the smell gone. Removing a shower drain smell is a quick process that involves only common household products.
Remove the drain trap or cover from the drain hole. Some drain traps are just pried off with a screwdriver. Others are secured with screws that need to be loosened before removing the trap or cover. Use a wire coat hanger to remove any visible debris or clogs from the drain.
Fill a pot with one gallon of water. Put the pot on the stove, and bring the water to a boil.
Pour the boiling water slowly down the shower drain. Use hot pads and pour the water carefully to avoid burning yourself.
Pour one cup of baking soda down the drain hole. Let the baking soda sit in the drain for 30 minutes.
Pour three cups of distilled white vinegar into the drain hole. Plug the drain hole immediately with a rag or drain plug to prevent the fizz that's created from coming out of the drain.
Let the baking soda and vinegar sit in the drain hole for at least three hours, or until the next time you take a shower. The longer you leave the mixture in the drain the better. Repeat this entire process, if necessary, until the odour is gone.
