What Are the Main Health and Safety Concerns in New Zealand School Washrooms?

If your school was to be audited for the levels of its washroom hygiene, what would they find?

No school wants to be singled out or receive a parent’s letter of complaint about the school’s toilet conditions.

The washroom is one of the most frequented spaces in your school, mostly by students but also by parents when they’re in for parent-teacher appointments and any other visitors.

You want your school to make a good first impression. Having a well-kept washroom isn’t only about cleanliness, it’s about maintaining your school’s reputation.

Here are some of the complaints you may get and how to address them.

School Washroom Guide Pathogenic Agents

  • “Some wash basins had tap water too hot.“
  • Make sure your hot water doesn’t exceed 43 degrees Celsius – the safest maximum temperature that minimises the risk of scalding. Use mixer taps whenever possible, so students can easily set a comfortable temperature that encourages regular hand washing.
  • “Some toilets are deficient in gender signs or they aren’t prominent enough to show whether facilities are to be used by girls or boys.“
  • Inadequate signage is easily solved by downloading free toilet gender signs and installing them at the appropriate height.
  • “Many children avoid using toilets because they are dirty, which can lead to incontinence and dehydration.“
  • “Holding it in” has been linked to dehydration and constipation, as well as poor concentration and recurrent urinary tract infections in children. So make sure to maintain your school washrooms regularly and promote regular toilet use among students. Contact the New Zealand Continence Association and use their Toilet Tactics kit to raise awareness of healthy bladder and bowel habits in your school.
  • “There are not enough hygiene supplies available, such as paper towel units and liquid soap dispensers.“
  • There’s no proper school hygiene without proper hygiene supplies. Be sure to maintain washroom standards by appointing one of your staff as a facility manager to ensure facilities are well-stocked at all times during school hours. Alternatively, let the professionals take care of it for you. Renting washroom accessories is the quickest and cleanest solution, especially if you have large facilities to run. Fresh & Clean manages everything for just a few dollars a dayOur powerful germ-fighting hygiene products help keep your students healthy, happy and productive, even during the flu season. Have a look at our managed rental hygiene program today. Your school will thank you.
  • “Sanitary disposal bins aren’t equally accessible in all female toilets.“
  • Sanitary towel disposal units should be installed in all female cubicles where age appropriate, including primary and secondary schools, and should be regularly serviced.
  • “Toilet cubicle design is inadequate and potentially dangerous.“
  • Floor-to-ceiling cubicle doors allow for added privacy, but they can compromise children’s safety. The case of a boy’s tragic death at Napier school in 2016 turned the spotlight on designing school toilet cubicles with ceiling level space for added safety. Where possible, install cubicles with ceiling level space that ensures emergency access and discourages antisocial behaviour.

How Many Toilet (WC) Pans and Washbasins Does Your School Need in New Zealand?

New Zealand’s Ministry of Education’s regulations don’t specify the minimum requirement for toilet (WC) pans and washbasins in schools. However, there are government guidelines that serve as a reference when designing or refurbishing school washrooms.

Here are the general requirements for school washrooms required by the Compliance Document for New Zealand Building Code.

This table helps calculate the required number of toilets for staff and students, as well as the ideal staff and student toilet ratio.

What Are the Standard School Toilet Cubicle Sizes for New Zealand Schools?

School sanitary facilities should be designed specifically for children.

  • Fixtures, fittings and toilet accessories should be placed at a suitable height.
  • Cubicles should be sized according to different age groups using them.

The Ministry of Education’s Reference Design Guide (2017) recommends that “Toilet doors shall have a 25mm undercut to allow for make-up air to the cubicle.”

Here are the recommended measurements of toilet cubicle doors and walls in relation to different median heights within different age groups.

The Best School Washroom Hygiene and Safety Practices – Complete Checklist

Putting a large number of children in a school environment creates ideal conditions for spreading infectious diseases. Getting school washroom hygiene right is the first line of defense in the fight against disease.

A New Zealand survey of 68 schools in the South Island revealed that only 28 per cent provided warm water, liquid soap at every basin and functional hand drying facilities.

These results are concerning given that providing students with appropriate washroom facilities is the key ingredient in preventing the spread of colds, flu and gastro bugs.

The following washroom hygiene advice will help you maintain a healthier and happier school environment.

1. Choose easy-to-clean school washroom design

It’s all about keeping it clean – regularly and thoroughly. Steer clear from excessive tiling, impractical colours that hide dirt and overly complex designs.

Scientific tests have shown that sink taps are one of the dirtiest areas in the washroom, right after toilet floors and toilet bowls. So, choose a practical low-maintenance design that is easy to clean. Preferably, infrared sensor taps.

Choose the following design elements to extend the life of your school toilets and minimise maintenance requirements:

  • Easy-to-clean toilet fixtures. Floor-mounted back-to-wall toilet pans are much easier and simpler to clean than conventional toilet designs.
  • Chemical-resistant toilet cubicles. Smooth surface materials are resistant to even the harshest detergents as well as graffiti and dirt.
  • Concealed toilet flush cisterns. Cisterns integrated into the wall create extra space and reduce cleaning time.
  • Low-maintenance washroom tiling. Choose tiles with easy-clean finishes, such as polished porcelain. Go for larger over smaller tiles as they allow for less grouting which attracts dirt and grime. Use 300 x 600mm dimensions for walls and 300 x 300mm for flooring.
  • No-tile washroom design. Durable, 100% waterproof wall panels are ideal for wet area walls and flooring, and minimise the need for grouting.

2. Install no-touch school washroom accessories and hardware

To reduce the potential of spreading illness, you need to minimise the risk of cross-contamination by reducing the number of common contact points that act as hotspots for germs and bacteria.

Washroom taps and sinks are typically the most highly contaminated surfaces used by pupils – even more so than the toilet pans themselves.

School Washroom Guide Bacteria Count Graph

3. Provide proper school washroom hand washing and hand drying facilities

Ensure that your washrooms are well-stocked with all the necessary washroom supplies such as soap dispensers, paper towels and toilet rolls. Install automatic alternatives whenever possible to reduce cross-contamination chances in your school.

Hand sanitisers are the most effective method for preventing viral and bacterial contamination, particularly, powerful alcohol-based sanitisers.

For hand drying solutions, any quality hand-drying product will dry hands.

However, paper towel dispensers have been shown to be the most effective. While air dryers do dry hands quite well, they can actually increase bacteria levels by up to 254% on palms and 194% on finger pads.

The most environmentally-conscious solution is to use cloth towel dispensers, which are as effective as paper towels, but produce zero waste.

4. Use fun posters to encourage hand hygiene among school children

School children’s awareness of the importance of regular, proper hand-washing is critical. Children are naturally curious and touch everything they find interesting. They also don’t discriminate between using clean tissues and the back of their hands if they have a runny nose.

However, with a little effort and some motivational visuals, your pupils can develop good washroom habits that will protect their long-term health.

5. Dispose of school washroom waste properly

Hygiene Poster

Waste disposal is also important. By fitting your school premises with proper waste disposal units, you help prevent airborne germs from spreading and compromising children’s health.

6. Install school washroom toilet seat sanitisers for better germ protection

Toilet seats are high-contact fixtures and require special attention to ensure they are not a threat to children’s health.

A 2014 experiment took samples from a keyboard, a doorknob, a table, a toilet seat and a few other general purpose objects. The sample from the toilet seat was shown to have the highest bacteria count than all the other observed objects in the experiment.

Flushing the toilet actually disperses airborne bacteria that are breeding in the toilet pan.

Installing toilet seat sanitisers in your school toilets helps prevent harmful bacteria build-up on the surface of school toilet seats.

Combine seat sanitisers with powerful auto washroom sanitisers for an easy 24/7 sanitation solution.

bacteria in toilet seat

7. Provide adequate school washroom odour control

Unpleasant odours from school washrooms and toilets are typically due to the build-up of uric acid crystals in urinals and toilet pans and the bacteria living in those crystals.

Cleaning agents based on harsh chemicals and waterless urinals do little to combat the odour issue.

The most effective method of neutralising bad odours is to:

  • Install high quality, programmable automated air fresheners using natural ingredients that help you maintain a consistently fresh and clean washroom
  • Commission a thorough bio-cleaning treatment using natural probiotic cultures to remove odour-producing bacteria from the system long-term

8. Employ additional school washroom safety measures

Install anti-trap hinges, self-closing doors and non-slip mats to minimise the potential for accidents and injury.
