Why Do They Put Ice in Urinals? Exploring the Science, History, and Benefits of This Common Practice


Have you ever used a public restroom and noticed there is ice in the urinal? If you have, you are not alone. The practice of putting ice in urinals is common in many places, but have you ever wondered why? In this article, we will explore the science, history, and benefits of this common practice.

The science behind urinal ice: Understanding the benefits

Many people wonder why urinal ice is used and what benefits it provides. From improving hygiene to reducing odors, there are many benefits of using ice in urinals. One of the main benefits is that it may help keep the urinal clean. Urine, while sterile when it leaves the body, quickly becomes an excellent breeding ground for bacteria and other microorganisms. By putting ice in urinals, this germs’ growth can be slowed down, making it easier to keep the urinal clean and in good condition.

Another benefit of ice in urinals is its cooling effect. When urine hits the ice, it cools quickly, which can help reduce unpleasant odors. It also reduces the moisture level in the air, which can be helpful in areas where there is little ventilation, such as busy restrooms. Additionally, the reduced moisture can be helpful in preventing mold and mildew growth in some instances, further contributing to a cleaner and healthier environment.

A history of using ice in urinals: Where did the trend come from?

The practice of putting ice in urinals may seem like a relatively recent development, but it has actually been used since the early 1900s. At that time, ice was placed in urinals to cool them and reduce the spread of germs, which were more common due to the poor sanitation practices of the time. In the 1930s, urinal cakes and other odor-control products began to replace ice in many public restrooms.

However, the trend of using ice in urinals has remained popular in many areas, particularly in bars and restaurants. Some speculate that this is because it is an inexpensive way to keep a restroom clean and smelling fresh. Others believe it is due to tradition and the fact that many people associate ice in urinals with high-end establishments such as fancy hotels and upscale restaurants.

The hygienic advantages of using ice in urinals: A myth or a fact?

Many people believe that using ice in urinals can help prevent the spread of germs and improve hygiene. However, the validity of this claim is uncertain. While ice can help slow down the growth of bacteria, it is not a substitute for regular cleaning and disinfecting of restrooms.

Additionally, in some cases, the melting ice can actually contribute to unsanitary conditions in the restroom by creating standing water, which can harbor bacteria and other germs. Therefore, while ice in urinals can help improve hygiene to some extent, it should not be relied upon as the sole method of maintaining a clean and sanitary restroom.

The ecological impact of using ice versus alternative solutions

When considering whether to use ice in urinals or other methods of urinal maintenance, it is important to consider the environmental impact of each option. While ice is generally considered a relatively environmentally friendly option, it still requires a significant amount of energy to produce and transport.

Additionally, the water used to make the ice and cool the urinal may be wasted if the ice melts before it has a chance to work. On the other hand, many alternative methods of urinal maintenance and odor control, such as waterless urinals and biodegradable cleaning products, may be more environmentally sustainable and efficient.

How putting ice in urinals affects the overall bathroom experience for men

While the benefits of using ice in urinals are clear, some men may find it uncomfortable or inconvenient. For example, the cooling effect of the ice may be unpleasant for some users, particularly those with sensitive skin. Additionally, the placement of the ice can sometimes make it difficult to aim. Some men may also find the sound of the ice melting distracting or unpleasant.

Ice in urinals as a way to reduce odors: An effective solution?

One of the most commonly cited benefits of using ice in urinals is its ability to reduce unpleasant odors in restrooms. While this claim has some merit, ice is not always the most effective solution. Alternative odor control methods such as air fresheners, deodorizing urinal screens, and automatic cleaning systems may be more effective in some cases.

No more ice in urinals: Exploring alternative options and their effectiveness

For those who are looking for alternative methods of urinal maintenance and odor control, there are many options available. Waterless urinals, which use gravity instead of water to flush, are becoming increasingly popular in many areas. Biodegradable cleaning products are also a good alternative to harsh chemicals and can be just as effective.

Regardless of which method you choose, it is important to regularly clean and maintain restrooms to ensure they are clean, hygienic, and pleasant for all users.


In conclusion, the practice of putting ice in urinals has both benefits and drawbacks. While it may help reduce germs, unpleasant odors, and other unsanitary conditions, it is not a substitute for regular cleaning and maintenance. It is also important to consider the environmental impact of ice and other methods of urinal maintenance, and to choose the method that is most sustainable and efficient.

Ultimately, the decision to use ice in urinals or other methods of urinal maintenance will depend on a variety of factors, including personal preference, cost, and environmental concerns. Regardless of which option you choose, the most important thing is to stay committed to maintaining clean and hygienic restrooms for all users.
