How Do Utilities Work in Tiny Houses on Wheels?
You’ve seen beautiful tiny houses on wheels on TV, in magazines, and on the internet. You could see yourself buying a tiny house one day. You could use it for vacations, put it in your backyard to use as a studio or guest house, or you could live in your tiny house full-time.

But you may have asked yourself: if it’s on wheels, how does it really work? How do you get power to a tiny house? How do you get fresh water in and waste water out? How are tiny houses climate controlled? What expenses are you forgetting to include in your overall budget?
There’s a lot more to buying a tiny house than just buying the tiny house. You’ll need to have a good understanding of how it all works, and how you’ll deal with fresh water, waste water, power, and parking. There are many options for different types of tiny house setups. Before building, your builder will need to know how you plan to use your house so he or she can help you choose the best appliances and systems for your specific situation. Read about tiny house design sessions.
Setting Up Your Tiny House
Because they’re on wheels, tiny houses can travel. However, life on the road isn’t for everyone: most tiny house dwellers live in one place with permanent utility connections.
If you’re traveling with your tiny house:
- Buy a truck powerful enough to pull your tiny house. Here’s an article on truck capacity for different tiny houses.
- Make sure to let your builder know they’ll need to insulate for all climates. When traditional houses are built, they are insulated according to what zone they’re in. Houses in colder climates need a lot more insulation. But when a movable house is built, it needs to withstand all kinds of weather.
- Tiny houses that travel go through a lot of wear and tear. The amount of wind and vibration a tiny house experiences when driving on the highway is the same as if the house were sitting still in a hurricane. Secure your items well inside your tiny house, and prepare to perform more maintenance on your tiny house since it will be traveling often.
- Make sure you know where you’ll be traveling to (RV parks? Friends’ houses?) and where you’ll store your tiny house when you’re not staying in it. It’s not always easy finding places to put your tiny house, so it pays to be prepared!
- In the same vein, research the cost of renting space, what utility hookups are required, and include your transportation costs, like fuel and road food, in your budget. Check out this article on the all-in cost of living in a tiny house.
- If you plan to sell your tiny house when you’re done traveling, make your resale easier by buying a tiny house with a layout that’s as universally appealing as possible.
If your tiny house will stay in one place:
Most people place their tiny house on a gravel or concrete pad. This keeps utility lines in place and systems working properly (for example, some mini splits can leak if they’re not level).
Anchors are a great idea: they’ll keep your house from shaking even in the worst weather.
Skirting, while not necessary, also reduces shaking in high winds, and, if insulated, helps keep your pipes from freezing. Skirting creates a more permanent look to your tiny house.
If you don’t have a location for your tiny house yet, here are some things to consider when looking:
- Make sure zoning will allow you to live in your tiny house (if not, consider opting for a tiny or small house on a foundation). Rural towns will generally have less restrictive zoning laws than suburban or urban ones. Here’s an article on how to find out if your town will allow you to live in a tiny house on wheels as your permanent residence.
- Buying land that already has utilities (water and power) is generally less expensive than buying raw land and having utilities installed. Read this article on buying land for a tiny house for more information.
If you’ll be placing your tiny house in a backyard, here are some tips:
- Tiny houses on wheels are generally legally considered RVs, so if you can park an RV in your yard, you can park a tiny house in your yard. Whether it can legally be lived in full time is a different question. You’ll have to find out from your town’s zoning board. Here’s how.
- Choose a spot in your yard for your tiny house wisely. In addition to the space the tiny house will take up, you’ll need to ensure the delivery truck will have enough space to maneuver the house into place and then drive away.

Tiny House Water Systems
When people envision life on the road, they picture a life of freedom. But if you’re a human, you’ll still need water for life’s basics: drinking, cooking, and bathing.
RV Hookups for Water
For water, RV hookups come standard on B&B Tiny Houses. RV hookups have an inlet for a fresh water hose and an outlet for waste water. You can connect the hoses to a hookup pedestal at an RV park or, if your tiny house is in a backyard, to the main house.
Tiny houses on wheels have four potential spaces where water is used: kitchen sink, bathroom sink, shower or bath, and toilet. Depending on whether you’ll be traveling or staying put, and what systems are available at your location, we’ll help you decide on the best type of toilet for your lifestyle.
If you’re traveling, here’s how to hook up your tiny house at a campground:
Some tiny houses have water tanks and some don’t. If you’ll always be hooked up to a water system when you’re using water, you won’t need water tanks.
If your tiny house has water tanks, the tanks can store fresh and waste water until your house gets to a pumping station.
If you have water tanks, here’s a video on how to empty waste water (black water) tanks at a dumping station.
Permanent Tiny House Hookups
If your tiny house is staying in one place, you’ll want a more maintenance-free water system. Tiny houses on wheels can be hooked up permanently to the same systems traditional houses use: a well or city water for fresh water, and septic or sewer for waste water.
If your tiny house is in the back yard of a traditional house, you can hook your tiny house up to the existing water system, as long as it has the capacity to add another “bedroom”, which is code for “the water usage equivalent of one or two people being added to a house”. Generally, when houses are built, the water system permits the house to add at least one extra bathroom, in case the house gets an addition in the future.
- If the main house is on city water, you’ll need to check town records to see if the house is permitted to add another hookup to the water system. Check with town records to see if this is true in your situation. Most often (but not always) when houses are on city water, waste water will go to a city sewer.
- If the main house is on a well, check to see if the well will need to expand its capacity to provide enough water for the tiny house. Most often (but not always) when houses are on a well, waste water will go to a septic system.
Generally, we advise our customers not to DIY sewer connections, as there’s too much that can go wrong. However, we want you to have an understanding of how it’s done, so please watch the following video of how one DIYer connected his RV to the sewer.
- Contrary to what this DIYer did, we advise having a trench dug by site work professionals to bury your water lines. This is for aesthetic reasons as well as to prevent freezing. If your water lines are above ground and you’re using your tiny house year-round in a climate that freezes, wrap your hoses in heat tape from an RV supply store.
Tiny House Power Sources
Power is the second most important utility your tiny house will require. If it’s good weather outside, you can survive without using power, as if you’re going camping. But if you want to take a hot shower, operate lights and other electronics, and generally live like a modern human, you’ll need a constant source of power going to your tiny house.
- Most tiny houses on wheels come with RV hookups where you plug an extension cord with an adapter into the side of your house.
- These connections work best for those who plan to use electric appliances like ovens or washer/dryers in their tiny house.
- If you’ll permanently anchor your tiny house, however, you can have your builder put a permanent power receptacle in. It’ll go either underneath your house so the wires can be buried, or near the roof of your house so you can run overhead wires.
- Solar power systems are another option. Installing solar systems is much more expensive up front, but they can pay for themselves after 10 or so years.
- If you want an off-grid solar system that powers your whole house, you’ll need to set aside outdoor space for solar panels and indoor space like a closet for batteries and the control center. You’ll need to choose your appliances to work well with solar energy (for example, choose a gas fireplace instead of an electric heater) and use energy conservatively.
- Most people use grid-tied solar, which supplements power from the power lines and sells energy back to the grid when you’re not using it all (your meter will run backwards!) Another advantage to grid-tied solar is you won’t run out of energy on a cloudy day, because when your batteries are depleted your system will automatically switch to grid power.

Picking the Best Solar Power Option
Many tiny home owners chose to adopt the minimalist lifestyle in order to live more sustainably. Solar panels offer a great form of renewable energy, but there are many considerations that you will need to keep in mind before you decide if solar power is the right option for you. In this post, we will talk about the differences between grid-tied and off-grid solar power.
Grid-Tied Solar Systems
As the name suggests, grid-tied solar systems connect to a utility power grid.
– Net metering: Net metering is when excess energy created by your solar panels is sent to the utility power grid for others to use. This allows solar panel owners to be paid for the excess electricity that their panels create.
– On-grid Connectivity: If the solar panels do not create enough power for your tiny home, then the electrical grid will give electricity to your home as needed. This can allow a tiny home owner to buy solar panels in phases and increase the amount of panels their home relies on whenever the owner pleases.
– Affordability: Grid-tied solar power is the cheapest option for solar energy.
– Lack of Transportability: Many tiny home owners like to frequently move around with their tiny house. Because of this, a grid-tied system would not be the ideal choice because they might not have access to an electrical meter while on the move.
Off-grid Solar Systems
Off-grid systems are able to move with tiny home owners as they travel. Off-grid systems work by converting sunlight to power during the day and then storing this power in batteries for future use.
– Transportability: With this option, you are able to travel with your tiny home and have a source of power.
– On-grid connect-ability: There are off-grid options that can also connect to the grid, which enables tiny home owners to not have to worry about not having electricity and allows owners to sell back surplus electricity.
– Price: Compared to grid-tied systems, off-grid systems cost more money. In order to prevent a lack of power, most off-grid systems are oversized to make sure that there are no outages; this usually takes into consideration 1-2 days without solar panel generation.
– Lack of Electricity: Solar panels may not produce enough electricity due to weather or because your tiny home is using more power than predicted. As discussed above, this is why most off-grid systems are oversized. Tiny home owners do have the option of charging the batteries via a generator if there is not enough solar power produced.
Depending on how you are wanting to use your tiny home and budget will probably be most tiny home owners’ biggest considerations when deciding which solar system to opt for.
Hooking up a tiny house to power, fresh water, and waste water is easy– just plug and play!
From left: the tiny house power source, an extension cord with an adapter to fit into any three-pronged outlet; the water hose inlet; and covered outdoor outlets for all your chili-pepper-string-light needs. Not pictured: grey and black water outlets, under the house.
First, you’ll need a source for fresh water in your tiny house. You can source water from a town water line, a well, or any other potable water source.
Tiny houses that stay in one location can hook up to water through an RV hookup, which includes an underground water source with a pedestal that feeds water into the sinks and other faucets as they are used.
If there are water tanks in your tiny house, they can be filled with potable water via a hose, whether the hose is permanently attached to a stationary house (in freezing temperatures, wrap heat tape along the hose), or, if you’re traveling with your house, intermittently. You can also have a water truck come and fill up your water tank, although that’s a more expensive solution.
How will you get rid of your waste water?
Depending on what your town allows, you may separate your grey water from your black water if you can use your grey water, or you may put all waste water into black water. Grey water may be used in irrigating gardens (again, as long as your town allows it) and you use eco-friendly soap products. More on greywater use is here.
Either way, your waste water will need to go somewhere! B&B Micro Manufacturing can build in grey and black water tanks to your tiny house, or you can permanently tie-in your tiny house to a septic or sewer system.
The simplest, cheapest power source for your tiny house is running an extension cord a building that already has power. Many people who live in their tiny houses full-time park their houses beside or behind the house of a friend, relative or landlord. Others may lease or purchase a property that already has a power source. If you need to have new power lines run to your property, check in with your town. Learn more about connecting undeveloped land to power and water sources here.
Solar powering tiny houses is another option, albeit the most expensive one. Off-grid solar power systems for tiny houses, including solar panels and batteries, cost anywhere between $3,500 and $10,000, depending on your power needs. If you’re choosing solar power for your tiny house, we will help you choose the most energy-efficient appliances for your power system. You can read more about your solar options and our tiny house solar energy partner, AltEStore, here.
The TL;DR* for tiny house water and power is that tiny houses work just like RVs, and they can be quite simple and easy to plug in.
