There is nothing nicer than a shower to shake off all the tiredness and stress. Too bad, though, that this moment is not always so idyllic! Sometimes, in fact, it happens that we enter the shower stall and are hit by a sewer smell coming from the drains. Sure, we may have tried pouring various products down the drains to get rid of that smell right away, but it did little good: the stench is still there! But fear not! Today, in fact we will see some natural tricks that can remove the sewer smell that persists in the shower!

Baking soda and citric acid

The first remedy involves the combination of two ingredients that act as disincentives and have the ability to neutralize bad odors: baking soda and citric acid. Together, in fact, they are able to generate a mechanical reaction that will help them unclog drains clogged with hair or other buildup. All you need to do, then, is to pour 1/3 lb. of citric acid into a quart of warm water and, in the meantime, pour ½ lb.of baking soda down the drain. At this point, wait a few seconds and pour, then, the mixture with citric acid into the shower drain as well. To make this remedy even more effective, you can also cover the drain area with a wet cloth. Finally, pour a small pot of very hot water to rid the drain of all residues: goodbye sewer smell in the shower!

N.B Please remember not to use citric acid if you have a marble or natural stone shower because it may corrode it.

Vinegar and lemon

Another very effective combination of ingredients is vinegar and lemon, which are known for their cleaning, degreasing properties! In addition, they also boast a strong anti-scale action! We remind you, in fact, that they are also a godsend for removing lime scale stains from bathroom fixtures!

So, add, in a bowl, 1 cup of vinegar and the juice of half a lemon. After that, stir the mixture before pouring it into the shower hose and leave it overnight. Finally, rinse the channel thoroughly with cold water. And voila: the sewer smell will be just a bad memory!

N.B There is a long debate about the use of vinegar in drains, as it seems that its approach is not really environmentally friendly. So, ideally, alternative methods should be preferred, first and foremost citric acid. Please remember not to use this remedy if you have a marble shower.

Lemon cap

Lemon, however, can be used not only with vinegar but also on its own with the lemon cap trick, which is able to eliminate sewer stench and bring a fresh scent to the whole bathroom! Therefore, equip yourself with:

  • 1 lemon (it needs to be big enough)
  • 2 tablespoons of baking soda
  • 2 cups of water
  • Lemon essential oil

Begin, then, by pouring the water into a small saucepan and heating over low heat until it comes to a boil. After that, dissolve the baking soda in the water. Meanwhile, cut the lemon slice starting from the center so that you get a larger slice and pour, instead, the juice of one lemon into the water and baking soda solution.

Once you have prepared everything, all you have to do is place the lemon slice on the shower drain and then pour the very hot solution of water, lemon juice and baking soda over it. You will notice that not only will you have cleaned and neutralized the bad smell in the shower drain, but the steam from the hot water on the lemon will also make the scent spread throughout the bathroom!


Another pantry ingredient that can deodorize odors is salt, which boasts a strong absorbent action. In fact, we remind you that it is used to make DIY scented moisture absorbers! Again, we combine it with baking soda in order to make the remedy more effective. So, add 1.2 lb. of baking soda and ½ lb. of salt to the shower drain, after which pour a pot of boiling water slowly down the drain and leave it to work. Finally, rinse, and the clogged shower drains will be free and odor-free!

Brewer’s yeast

Finally, here is one last remedy that can absorb and remove the sewer smell in your shower: brewer’s yeast! Dissolve, then, a piece of brewer’s yeast in a saucepan containing 1 cup of boiling water and pour, then, the resulting mixture into the shower drain. Leave it overnight, after which you rinse and notice that the sewer smell will be gone! In addition, this ingredient also turns out to be very effective in removing the stench in the toilet!


Remember that in case of a strong odor that does not go away with natural remedies, it is advisable to seek advice from a technician. Be very careful when handling boiling water.
