Big Considerations - Water, Electricity, and Sewage

The tiny house movement has taken the world by storm, and for good reason. As more people aim to minimize their carbon footprint, simplify their lives, and optimize their finances, tiny homes offer a charming and practical solution. But while the idea of a compact, minimalist dwelling might be tempting, it's essential to remember that these houses come with their own unique challenges. One significant area to consider is utilities: water, electricity, and sewage.

While the great advantages of tiny houses, such as affordability, simplicity, mobility, and environmental friendliness, are incredibly appealing, utility considerations can make or break your tiny house experience. You can read a bit about it in our FAQ section on the website!

Water: The Quintessential Element of Life

For homeowners of conventional dwellings, the availability of clean water is often taken for granted. However, when we venture into the realm of tiny houses, particularly those designed to be mobile, the scenario takes a different hue.

  • Connected to Main Supply: For those who've chosen to anchor their tiny homes in a fixed location, such as a garden or an eco-village, tapping into the primary municipal water supply can be an achievable goal. This direct approach is most akin to traditional living, ensuring continuous water access without the need for frequent manual intervention.

  • Rainwater Collection: Embracing the green spirit, many tiny homeowners are adopting rainwater harvesting techniques. This involves setting up systems to collect, purify, and store rainwater for daily use. The efficiency of such a system is influenced by regional weather patterns and individual consumption habits. In arid regions or during dry seasons, backup water sources might be indispensable.

  • Portable Water Tanks: Tiny house nomads often rely on portable water tanks. These tanks, while convenient, demand periodic refilling. Given their limited storage capacity, strategic planning about water sources becomes essential. Beyond just consumption, water availability also plays a crucial role in daily chores, from cooking to cleaning.

  • Water Heating Solutions: Tiny doesn't mean compromising on comforts. Modern, compact, on-demand water heaters have made it feasible for tiny homeowners to enjoy hot showers even in the most confined spaces. They are space-saving, energy-efficient, and cater perfectly to the tiny living ethos.

Electrifying Realities: Powering the Tiny Home

Electricity is the unsung hero of our daily lives, powering everything from our reading lights to our refrigeration.

  • Traditional Hookup: Just as with water, stationary tiny homes have the advantage of connecting directly to the municipal electrical grid. It offers the reliability of steady power, though some purists feel it strays from the ethos of total self-reliance associated with tiny living.

  • Solar Panels: Solar panels are the poster child for sustainable living. For the environmentally aware tiny house dweller, solar panels, combined with effective battery storage, can fulfill daily electrical needs. However, the efficiency of solar solutions hinges on geographical location and daily sun hours. Moreover, there's an initial investment to consider, which, although substantial, pays off in the long run.

  • Generators: For those frequently changing their locales, portable generators serve as reliable power sources. They come with their own set of challenges: the operational noise, the need for regular fueling, and emissions. However, they're invaluable for those seeking off-grid living without solar infrastructure.

  • Battery Systems: With advances in technology, we now have high-capacity batteries capable of storing substantial power. Whether charged from the grid, solar panels, or generators, these batteries ensure that the lights stay on even when the sun doesn’t shine.

Sewage: The Essential, if Uncelebrated, System

Effective waste management is paramount for health, sanitation, and environmental conservation.

  • Traditional Sewer or Septic Systems: For tiny homes in suburban or community zones, connecting to established sewage systems or installing a small-scale septic system ensures waste is processed safely and hygienically.

  • Composting Toilets: An innovative solution for mobile tiny houses. Composting toilets break down waste biologically. When maintained appropriately, these toilets are efficient, environmentally friendly, and surprisingly odor-free. Plus, the resultant compost, while not suitable for edible plants, can nourish ornamental gardens.

  • Portable Waste Tanks: Similar in concept to the portable water tanks, these are meant for waste collection. Periodic disposal at designated facilities is essential to prevent health hazards.

  • Greywater Systems: A holistic approach to water conservation, these systems collect and treat 'used' water from showers and sinks. Post treatment, this greywater can irrigate gardens. However, meticulous filtration and monitoring are essential to ensure that this recycled water doesn't harm the environment or human health.

The Takeaway

While tiny houses promise an idyllic and simple lifestyle, the logistical considerations, especially around utilities, are substantial. Whether you're contemplating downsizing or just fascinated by the concept, it's crucial to appreciate the nuances behind the scenes.

Planning, research, and a touch of creativity are essential to ensure your tiny home doesn’t face big problems. Addressing utilities with the same enthusiasm as design and décor will guarantee a comfortable and sustainable tiny living experience.


One significant obstacle in your considerations is surely your local building regulations. For aspiring tiny house owners in Europe, understanding building and utility regulations is crucial. Given the diversity of the continent, each country has its nuances. However, there are some common themes and regulatory concerns across the region when it comes to water, electricity, and sewer systems. To ensure you meet your national, regional, and local requirements and to stay up to date, please always contact your municipality.


  • Connection to Public Water Systems: In many European countries, if a tiny house is stationary and located within city or town limits, it may be mandatory to connect to the local water supply.

  • Rainwater Harvesting: European Union directives encourage sustainable water use. As such, several countries, including Belgium and Germany, have incentives for rainwater harvesting. However, in some places, if rainwater is used for indoor purposes (like drinking or showering), it must meet specific health standards.

  • Water Quality & Treatment: The European Drinking Water Directive ensures that water quality standards are maintained across member states. Any independent water sources in a tiny house would need to comply with these standards.


  • Grid Connection: In populated areas of Europe, connecting a stationary tiny home to the main electricity grid might be required. This ensures safety standards are maintained.

  • Alternative Energy Sources: Solar panel usage is popular and often incentivized in countries like Spain, Germany, and the Netherlands. Still, installations often need to meet EU-wide and national standards, ensuring they are safe and effective.

  • Safety Regulations: Electrical installations in tiny houses, like all dwellings in the EU, must comply with local and regional safety codes. The CE marking, a certification mark, indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).

Sewer & Waste Management:

  • Connection to Public Sewer Systems: Just as with water, many European municipalities require permanent structures to connect to public sewage systems. This ensures effective waste treatment and environmental protection.

  • Composting Toilets: While increasingly popular for their environmental benefits, composting toilets are subject to different regulations across European countries. For instance, in some regions of France, they're accepted as long as they adhere to sanitation and environmental standards.

  • Greywater Systems: Using greywater (from showers, sinks, etc.) for purposes like gardening is gaining traction in Europe. However, the EU's Urban Waste Water Treatment Directive means that greywater must be treated appropriately before being released into the environment. Systems must often be certified and regularly checked for compliance.

In Conclusion: Europe's diverse regulatory landscape can be challenging for prospective tiny house owners. Before embarking on the tiny house journey in any European country, thorough research and consultation with local authorities are imperative. This not only ensures legal compliance but also guarantees that the home is safe, sustainable, and environmentally friendly.
