How Do I Stop My Portable Toilet From Smelling?


Portable toilets have become an indispensable convenience for many outdoor events, construction sites, and other temporary setups.

However, despite their utility, maintaining a fresh scent in these units often poses a significant challenge. Over time, factors such as biological waste, inadequate ventilation, and infrequent cleaning can contribute to unpleasant odours that deter users. Recognising these common issues is the first step towards addressing them.

With nearly two decades of expertise in portable toilets and bulk waste removal in Western Australia, we’re going to share some of our tips on how to identify the root causes of these odours and how to effectively counteract them.


Understanding the Cause of Odour

Odour issues in portable toilets can be particularly unpleasant, but pinpointing the root causes is essential for effective resolution. One primary culprit is the natural decomposition of biological waste, which releases gases responsible for the unpleasant smell. This process can be amplified by a lack of proper ventilation, trapping these odours within the confined space.

Additionally, infrequent cleaning and maintenance can allow waste residues to accumulate, intensifying the stench over time. Also, it should be noted that not all cleaning and deodorising products are created equal. Opting for inferior or mismatched products can sometimes do more harm than good, failing to neutralise odours or even contributing to them. By understanding these key factors, one can make informed decisions on the best method to tackle and prevent these odour challenges.


The Essential Role of Regular Cleaning and Maintenance

A fresh-smelling portable toilet hinges significantly on regular cleaning and diligent maintenance. Adhering to consistent cleaning schedules ensures waste doesn’t linger and accumulate, which can rapidly intensify odour issues. Infrequent or irregular cleaning not only allows unpleasant scents to permeate but can also foster bacterial growth, posing additional health concerns. While individual efforts can make a difference, there’s an undeniable edge in seeking professional expertise.

Professional cleaning services are equipped with the right tools, chemicals, and know-how to ensure a deep and efficient cleanse, addressing every issue. With Instant Toilets & Showers, we offer hassle-free and thorough portable toilet cleaning services for all of our portable toilet hires to ensure that your toilets remain fresh and clean.

Quick Tips & Tricks to Minimise Odours in Portable Toilets

Give Your Portable Toilet Proper Ventilation

The essence of a fresh portable toilet often lies in its ability to breathe. Proper ventilation plays a pivotal role, allowing bad smells to dissipate and facilitating the influx of fresh air. Without this, odours become trapped, quickly overpowering the confined space.

To maximise natural airflow, strategic placement is key. Position your portable toilet in areas with open surroundings, away from obstructions like walls or dense vegetation. This ensures that prevailing winds can sweep through the vents effectively. Remember, a well-ventilated portable toilet doesn’t just smell better; it offers a more comfortable and pleasant experience for users.

Remember to Close the Toilet Seat

It’s essential to ensure the toilet seat is down in a porta potty after using. A closed toilet seat directs the holding tank’s fumes towards the ventilation tube, ensuring they’re properly expelled. Conversely, an uplifted seat can trap these odours inside the portable toilet, culminating in an unpleasant odour for the next user.

Monitor the Waste Tank’s Capacity

An overfilled tank can exacerbate odour issues and lead to potential spills. We strongly recommend routinely emptying the tank regularly to ensure the odours don’t linger and multiply.
