Bad smell in the bathroom? 7 professional solutions for the septic tank


A clean and pleasant environment in office, hospital or shopping center bathrooms directly influences the experience of employees, visitors or patients. Unpleasant odors, especially those coming from septic tanks, challenge the cleanliness standards and image of any organization. Beyond the state of discomfort, this situation can raise questions about how hygiene is managed. Precisely for this reason, effective solutions against this type of annoying odor become important for all those who manage commercial or institutional spaces. Our specialists offer you an updated list of 7 useful solutions and tricks, suitable for many types of spaces, which help you maintain fresh air and an impeccable image.

1. Periodically check unused siphons and drains

intervention on bathroom leaks

The siphon maintains a water barrier against odors in the sanitary network. If the space is not used for several days, the carbonated water can evaporate and the odor quickly reaches the bathroom. This is all easily solved: pour a liter of water down all unused drains at least once a week. Recommend this routine for cleaners, especially in hallway bathrooms or low-access storage areas.

If you notice the smell returning too often, also check the status of the soda. A broken or incorrectly installed siphon quickly fails. For example, in gyms or doctor’s offices with low seasonal traffic, dry soda can generate lingering odors until the water barrier is restored.

2. Install ventilation systems that suit your space

Proper ventilation helps quickly remove gases from septic tanks. In large spaces, the lack of an automatic ventilation system causes discomfort and can compromise general hygiene. Automatic fans with sensors perform well in heavily used bathrooms. In meeting rooms or rooms without windows, a centralized system guarantees constant air exchange and prevents the accumulation of steam and odors.

For clinics, hospitals or offices with strict hygiene requirements, fans with digital control are recommended. They only work if they detect humidity or presence, which reduces energy consumption, but always ensures clean air. For example, in conference centers, installing a ventilated system with a timer prevents the formation of unpleasant odors after events with many participants.

3. Plan maintenance and emptying of the septic tank

Timely maintenance of the septic tank prevents the occurrence of unpleasant odors and expensive blockages. Collaboration with a specialized company is determined by the frequency of use and the size of the tank. Institutions with many users, such as high schools or shopping malls, schedule emptying at an average interval of 6-8 months.

For additional control, use dedicated bioactivators and enzymes regularly. These products accelerate the decomposition of organic waste, prevent deposits and reduce gas emissions. Test ranges such as Ecolab or Asevi offering compatible solutions for medical facilities, commercial or industrial premises. For example, in an office building with 100 employees, the use of enzymes can keep the system odor-free between two consecutive emptyings.

4. Quickly removes problems from pipes and seals

Cracked pipes or worn fittings encourage gas leaks in public access rooms. The signs are easily recognisable: water collected at the base, traces of humidity on the walls or constant smells, no matter how meticulous the cleaning.

Use the services of an authorized maintenance company to check and replace the seals. For high-traffic spaces, such as restaurants or food court areas, proactively replace coverings annually. Prompt intervention avoids bad odors and possible structural damage.

5. Quickly apply odor neutralizing solutions

Remove the unpleasant odor using solutions you have on hand or professional products:

  • Pour the hot water with the enzymatic cleaner directly into the soda. The enzymes dissolve organic residues without damaging the plant.
  • Scented descaler (from the Ecolab or AQAS range) cleans deposits and stops the source of the odor. You can find such solutions in the form of tablets or concentrated liquids at Sanito. Explore our carefully selected range of toilet accessories, where you will find: toilet lids with toilet film, taps and accessories for sinks and showers, toiletries, urinal screens and hotel mirrors.
  • Use urinal tablets or dedicated solid deodorants (AQAS, Tork), they ensure long-lasting freshness. For example, in a supermarket, installing automatic air freshener dispensers with professional tablets completely reduced odors after each peak day.
  • For eco-friendly maintenance, combine baking soda with a little white vinegar and rinse with hot water. It works well in low traffic areas, but in high traffic areas or where optimal results are desired, specialized products are recommended.

Another particularly important tip is to air the room as soon as you notice an annoying odor: open the windows or use a fan. Opt for air fresheners suited to the volume of the room, and in public spaces focus on automatic programming systems for the dispersion of aromas (find variants from Asevi).

6. Adopts prevention routines and ensures training of maintenance personnel

A consistently sanitized space requires training cleaning staff and implementing clear routines. It uses bioactivators or biological enzymes that prevent residue buildup and block odors from anaerobic bacteria. You can opt for concentrated products or self-dosing tablets, easily distributed by cleaning staff.

Team instructions include:

  1. Do not flush tissues, grease or oils down the toilet/urinal as they will block the pipes and reduce the efficiency of the cesspool.
  2. Check the water level in the siphons regularly.
  3. Monitor the emptying frequency, adapted to the volume of the space (usually 6-12 months for large buildings).

Optimize these processes by using professional cleaning equipment available on our website. This way you reduce costs, increase efficiency and maintain the standard of “cleanliness in detail”.

7. Take advantage of modern odor control technologies

The technology helps quickly and predictably control the air quality in bathrooms and toilets. Install fans with occupancy sensors or centralized ventilation systems connected to digital building management. They work automatically and minimize manual intervention, which is particularly suitable for hospitals and high-traffic areas.

Furthermore, automatic enzyme or odor dosing systems provide good control at predictable costs. You can also request the customization of hygiene accessories, such as smart toilet lids with sensors, available through Sanito distributors. This option optimizes every square meter and ensures a high level of hygiene for users.

For example, a mall store that chose automatic fans and programmable air freshener dispensers significantly reduced odor intervals, increasing customer and maintenance staff satisfaction.

Monitor system performance and call specialists as needed

If the smell remains persistent after applying these precautions, carefully analyze the installation. Wetness in the joints, recurring blockages or an odor that is difficult to ventilate means that specialist intervention is necessary. Request a regular professional inspection, so that any non-conformities relating to pipes, seals or the ventilation system can be identified promptly. This step preserves the hygiene and comfort of the building and prevents possible sanctions.
