What’s the Cause of That Sour Smell in the Bathroom?

Sometimes acidic odors develop in bathrooms in homes. Even your best cleaning efforts won’t ruin the smell. If this happens at your home, the cause is likely bacteria growth in the shower or sink drain, mold growth in the grout, bacteria growth in the toilet bowl or tank, or a leak somewhere in the plumbing system. Some of these stains are hard to reach and come from a hidden place that starts in a hard to reach place that traditional cleaners can’t reach. If you have a pungent smell in your bathroom, here are all the possible causes and what you can do to fix it and get your bathroom smelling clean and fresh again.

Stinky shower drains

According to Hunker, one of the most common causes of bad smells in the bathroom is the growth of bacteria in the shower or sink. If you notice an odor from any of these areas, you can eliminate it and prevent it from coming back. Hair, soap, dead skin and other impurities are removed by the drain. Bacteria thrive in a moist environment, resulting in an acidic odor.

Cleaning of shower and sink tubes

To get rid of the sour smell, you need to remove the deposits and bacteria in the shower or sink drain. The first step is to remove all hair, soap scum and other debris that has accumulated in the shower drain. Most people use a straight bent wire hanger to remove plugs and other debris. After you have cleaned everything in the drain, make a cleaning solution of two cups of water and ¼ cup of baking soda. Pour this cleaner down the drain. Let it sit for 20 to 30 minutes. After this time, flush the drain with hot water. This should eliminate all bacteria and odors. If you still smell a slight sour odor, pour two cups of white vinegar down the drain and flush with hot water. This should solve the problem. The best prevention is to keep the drain free of hair and other debris that accumulates. It is also helpful to pour boiling water down the drain every month to prevent smelly bacteria from growing.

Other causes of bathroom odour

Len the Plumber points out that there are other causes of sour bathroom odors. Sometimes, in addition to maintaining shower and sink drains, poor maintenance can cause unpleasant odors. If the bathroom is not adequately ventilated, odors can develop. Excessive amounts of moisture from hot running water and steam from showers and baths can lead to mold growth. If a small space in the bathroom is not properly cleaned and maintained, moisture can cause mold to grow in that space. Corners and cracks are known to promote the growth of odor, mold and mildew bacteria. j

Tips for freshening up the bathroom and eliminating acidic odors

  • Ventilation System Installation/Maintenance – If your bathroom does not currently have a ventilation system, it is recommended that you install one. A small exhaust fan can help ventilate the room and circulate the air to reduce humidity and prevent the growth of bacteria, mold and mildew. If a ventilation system is present, check that the filter (if any) is clean and working properly to remove moist air.
  • Use a desiccant in the bathroom – desiccants are drying agents made from silica gel. They help absorb moisture in the shower. If you have children or pets, you should know that desiccant can be deadly if swallowed. You might consider using natural drying agents, such as plants. Lilies and ferns help dehumidify the air and eliminate unpleasant odors in the bathroom.

  • Deep Cleaning Mode – Other sources of acidic odors in bathrooms can come from the toilet or tank. The water can dry out and bacteria can grow rapidly in this environment.

To do this, simply pour white vinegar and wipe each part of the tank clean. When you’re done, flush the toilet and repeat the process twice.
  • Cleaning around the toilet – Use a disinfectant with a deodorant to clean the feet of the toilet and all parts of the outside. Toilets are a constant source of unpleasant odors. They should be cleaned thoroughly and regularly. Clean all fittings with a paste of baking soda and lemon juice. Apply to any surface to be cleaned and leave for 10 minutes. Spray baking soda with white vinegar and let it bubble for a few minutes, then wipe it off.
