With electricity and gas prices steadily increasing, even simple daily routines like taking a hot shower before work can have a noticeable impact on household budgets. What once seemed like a small luxury now raises a valid question: how much does a five-minute hot shower actually cost?

Shower or Bath: Which Is More Efficient?

When it comes to personal hygiene, most people prefer a quick shower to a long, relaxing bath. It’s faster, more convenient, and generally more energy-efficient—especially with modern showerheads designed to reduce water consumption.

On average, a typical shower uses about 95 liters of water, while filling a bathtub can require 150 to 200 liters. The exact number varies depending on your water pressure, the type of showerhead, and how long you stay under the stream.

Of course, if you enjoy standing under the warm water long after you’re done washing, that efficiency quickly disappears. Prolonged showers not only waste water but also increase your gas or electricity bills considerably.

The Hidden Cost Behind Hot Water

Every time you turn on the hot water tap, a complex system springs into action. Behind the scenes, your water heater or gas boiler starts working immediately, consuming energy to heat the water to your desired temperature.

When calculating the real cost of a hot shower, two factors must be considered:

1. The cost of heating the water (gas or electricity)

2. The cost of the water itself

Although both contribute to your utility bills, heating water is the more expensive part. In fact, domestic hot water production accounts for about 15% of a household’s total energy consumption, second only to heating in most homes.

Breaking Down the Numbers

Let’s take a typical example to estimate the cost of a standard hot shower.

Imagine a household of four people, each taking one five-minute shower per day. The water starts at an average temperature of 14°C and needs to be heated to about 50°C. With a 26 kW gas boiler running at an 85% efficiency rate, heating water for one shower requires about 0.49 kWh of energy per minute.

Currently, the price of gas is approximately €2 per cubic meter. It takes around 15 cubic meters of gas to heat 1,000 liters of water, which means that even a short shower adds up quickly.

When all the numbers are crunched, a five-minute hot shower costs roughly €2.50 per person per day.

If you take two showers a day—one in the morning and another after work—that cost doubles to €5 daily, translating to around €150 per month per person. Multiply that by the number of family members, and the monthly bill becomes significant.

How Energy Prices Amplify the Problem

Until a few years ago, the cost of heating water was relatively manageable. However, with the recent surge in energy prices across Europe, households have started to feel the pressure. Natural gas, in particular, has seen dramatic increases, making every degree of hot water more expensive.

Electric boilers or water heaters aren’t necessarily cheaper either. While they eliminate gas costs, electricity prices have also climbed, and electric heating systems tend to be less efficient overall.

What’s that hidden hole in the fridge for? It’s very useful, but few people use it.

This means that for many families, simply maintaining their usual shower habits could lead to hundreds of euros in extra utility expenses over the course of the year.

How to Reduce Shower Costs Without Giving Up Comfort

You don’t need to sacrifice comfort to save money—just make a few strategic adjustments:

1. Limit shower time. Reducing your shower from 10 minutes to 5 can cut your hot water use—and cost—in half.

2. Install a low-flow showerhead. Modern designs can reduce water consumption by up to 40% without compromising water pressure.

3. Lower the water temperature slightly. Even a 2°C reduction can noticeably decrease gas consumption over time.

4. Insulate your water pipes. This helps retain heat longer, meaning your boiler doesn’t have to work as hard to maintain temperature.

5. Check your boiler’s efficiency. Regular maintenance can improve performance and extend its lifespan.

6. Use timers or smart controls. These prevent your water heater from running unnecessarily when you’re not at home.

Why Short Showers Are the New Sustainability Habit

Beyond cost savings, reducing water and energy use has a positive environmental impact. Water heating is one of the biggest contributors to household carbon emissions. By cutting down shower time and energy consumption, you’re helping lower your carbon footprint.

For example, if every person in a family of four reduced their daily shower time by just two minutes, they could collectively save over 2,500 liters of water and 40 kWh of energy per month. That’s a win for both your wallet and the planet.

Final Thoughts

A relaxing hot shower might seem like a small daily indulgence, but its cost is far from negligible—especially as utility prices continue to rise. With current rates, those five minutes of warmth can cost around €2.50 per person, which may not sound like much until it adds up over weeks and months.

By being mindful of water use, maintaining your heating system, and adopting small energy-saving habits, you can still enjoy your morning shower without watching your bills soar.

In the end, it’s not about giving up comfort—it’s about finding smarter, more sustainable ways to keep it.
