It’s easy to overlook the toilets. But when something goes wrong, everyone notices… and by then it’s usually too late to fix.

At Instant Toilets & Showers, we’ve supported thousands of major events, sites, and emergency setups, and we’ve seen the damage poor planning can cause. From fines and shutdowns to complaints and bad press, it adds up real fast.

In this blog, we’ll walk you through the most common portable toilet planning mistakes, the hidden costs they create, and how you can avoid them with the right approach from day one.

Common Portable Toilet Mistakes

1. Underestimating Quantity and Ignoring Compliance

This is the big one. People often guess how many toilets they need, rather than following the guidelines from the HRIA or local council requirements. Too few units leads to long queues, unsanitary conditions, and unhappy guests or workers. Worse, if your setup doesn’t meet minimum compliance, you risk fines or even shutdowns.

At Instant Toilets & Showers, we take the guesswork out of it. Our team helps you plan based on actual usage data, and our online Toilet Hire Calculator makes it easy to estimate what you’ll need. We also make sure your setup meets all relevant standards.

2. Choosing the Wrong Unit for the Job

Not all toilets are created equal. A standard unit might suit a remote worksite, but not a black-tie wedding. Likewise, hiring regular units and forgetting accessible options can leave you open to discrimination complaints and safety risks.

At Instant Toilets & Showers, we offer a wide range of portable toilets for hire to suit every setting, scale, and standard (and not limited to just the below):

• Five Star Event Chemical Toilets – Perfect for public events, clean, compact, and efficient
• Six Star VIP Toilets – Premium, fully-appointed toilets perfect for weddings or private functions
• Five Star Streamline Pro Toilet – A high-capacity toilet block on wheels, ideal for larger events or high-traffic zones

With such a broad range, we’ll help you choose the right fit for your event or site to ensure nothing is missed and your big day (or project) runs smoothly.

3. Poor Placement and Site Access

Where you place your toilets matters just as much as how many you hire. Units placed on uneven ground, in low-visibility areas, or too close to food service zones can create safety risks, complaints, and logistical headaches. Poor access for servicing vehicles can also lead to missed pump-outs or delays, especially on busy event days or remote sites.

This is where the right planning (and the right equipment) makes all the difference. Some of our units, such as the Five Star Event Toilets with LED Lighting, are fitted with both internal and external LED lights, ensuring visibility and safety even after dark. It’s small details like this that set our range apart and show how we prioritise both user experience and functionality.

4. Forgetting Servicing and Maintenance Timing

Hiring toilets is only half the job. Keeping them clean, compliant, and functional throughout your hire is just as important. Skipping pump-outs, delaying cleaning, or relying on last-minute service calls can lead to blocked units, odour issues, and serious health risks. And once complaints start rolling in, the damage is already done.

At Instant Toilets & Showers, we don’t leave anything to chance. Our team handles ongoing servicing, scheduled waste removal, and responsive callouts to make sure your toilets stay in pristine condition.

We’ve also developed Toilet-iQ, our own remote monitoring system that tracks usage levels in real time. It alerts our team when waste tanks need servicing or when cleaning is due. It’s another way we lead the industry in smart, proactive solutions that keep your event or site running without interruption.

The Real-World Cost of These Mistakes

Getting toilets right means thinking ahead. When details are missed, things can quickly become more complicated than expected. Here are some of the common flow-on effects that can occur without proper planning:

• Fines and Compliance Breaches
• • • Local councils or regulators can issue penalties if your toilet setup doesn’t meet health, safety, or accessibility requirements.

• Site Shutdowns

• • • On worksites, inadequate sanitation can trigger a stop-work order until proper facilities are in place.

• Public Complaints and Reputational Damage

• • • Long queues, bad smells, or unsanitary conditions leave a lasting impression, especially at events or festivals.

• Health and Safety Risks

• • • Overflowing waste, blocked toilets, or poor hygiene increases the risk of illness and WHS breaches.

• Increased Cleaning and Damage Costs

• • • Underestimating usage often leads to overworked units, which break down faster and require emergency servicing.

• Lost Time and Stress

• • Chasing down cleaners, fielding complaints, or fixing problems mid-event takes attention away from the job at hand.
