Summary:
- A portable shower works by connecting to a water source (such as a mains line or rain water tank with a pressure pump) and using a hot water service (electric or gas) to provide hot water. Most units include a drainage solution like a waste tank or grey water hose. Some models are fully self-contained, while others connect to external utilities, making them perfect for worksites, events, or remote areas.
When you’re at an outdoor event or a remote worksite, having a clean shower can make all the difference. That’s where portable shower units come in. They might look a lot like those portable toilets you see everywhere, but inside, they’re all about giving you a refreshing shower.
These units are a game-changer, making it easy for people to stay clean no matter where they are. In this article, we’ll dive into what these showers are, how they work, and why they’re becoming so popular.
How The Portable Shower Has Evolved Over The Years
The birth of portable shower units traces back to the need for sanitation in places where permanent facilities were missing, such as music festivals, home renovations, or temporary work locations. The development and use of these portable showers surged during the late 20th century. Over time, improvements have been made to their design, functionality, and eco-friendliness. One notable milestone includes the integration of solar-powered heating systems, allowing for warm showers in remote places.
Today, these units not only ensure cleanliness but also offer a touch of modern comfort in the most unexpected locations.

How to Set Up a Portable Shower Unit (Step-by-Step)
Setting up a portable shower unit is a straightforward process, but attention to detail is crucial to ensure a seamless experience. Here’s a basic rundown:
1.Choose a Level Surface
- Avoid sloped or unstable ground to ensure safe positioning and even water flow.
2.Connect the Water Supply
- Use mains pressure where possible, or fill onboard tanks. Secure connections tightly to prevent leaks.
3.Set Up Waste Drainage
- Attach grey water hoses or connect to an external tank or re-cycle the water to your garden or grassed areas if suitable.
- Connect to LPG, electric, or solar power depending on your unit. Make sure power and safety settings are correct.
4.Test Water Flow and Drainage
- Run a short test to check pressure, heat, and water exit before regular use.
Challenges & Mistakes to Avoid:
- Not securing connections can lead to leaks.
- Ignoring drainage can result in overflow or pooling.
- Positioning under direct sunlight (unless using solar heating) can make the unit uncomfortably warm.
Proper setting up of the unit will not only ensure user comfort but also prolong the lifespan of the portable shower.
Best Tips to Ensure a Maintained & Hygienic Portable Shower
Maintaining cleanliness and hygiene in portable shower units is paramount for user health and the longevity of the unit. Regular cleaning prevents the buildup of bacteria, mould, and other undesirables. It’s advisable to:
- Regular Cleaning: Wipe down surfaces and the showerhead with a mild disinfectant after every few uses.
- Drainage Check: Ensure that drains are free from obstructions, preventing water stagnation.
- Water Source Inspection: Regularly check water tanks or hook-ups for any signs of contamination or algae growth.
- Component Review: Periodically inspect hoses, taps, and heating elements for wear or damage, replacing them as necessary.
By adhering to these best practices, one ensures a hygienic showering environment and extends the unit’s operational life.
Key Considerations When Choosing a Portable Shower Unit
Before selecting a portable shower unit, it’s important to evaluate the setup requirements, intended usage, and features that match your needs. Here are the key things to consider:
• Site Access & Space
- Ensure the unit fits the available footprint and can be delivered or towed into position, especially for tight sites or remote locations.
• Water Supply Compatibility
- Check if you have access to mains pressure water or if you’ll need an onboard water tank. This may affect your model options.
• Hot Water System
- Decide whether you need LPG, electric, or solar heating, as some sites may require off-grid options.
• User Volume & Duration
- Are you expecting high daily usage or occasional, short-term use? This will influence whether you need a single unit or a multi-cubicle block.
• Drainage & Waste Management
- Confirm how wastewater will be handled—through external grey water hoses, built-in tanks, or sewer connections.
• Accessibility & Comfort
- Look for features such as non-slip flooring, internal lighting, changing benches, mirrors, and accessible entry.
• Compliance Requirements
- If you’re working on a government or public-facing site, ensure the unit meets relevant standards like AS1428 for accessibility or NCC compliance.
