Tiny houses are small, often mobile, homes that typically range in size from 100 to 400 square feet. They offer a minimalist lifestyle that’s become increasingly popular in recent years. While they can be beautifully designed and incredibly functional, one of the most common questions people ask about tiny houses is whether or not they have a bathroom.
2. What is a tiny house?
Before we dive into the question of bathrooms in tiny houses, it’s worth defining what a tiny house actually is. Tiny houses are small, often mobile, homes that are designed to be incredibly efficient in their use of space. They can be built on a trailer or on a foundation, and they come in a variety of shapes and sizes. While there’s no hard and fast definition of what constitutes a tiny house, they typically range in size from 100 to 400 square feet.
3. Do all tiny houses have a bathroom?
The answer to this question is no – not all tiny houses have a bathroom. While some people may choose to forego a bathroom in order to save space or money, most tiny houses do have at least a toilet and a shower. The specific type of bathroom that’s included in a tiny house can vary depending on a number of factors, including the size of the house, the lifestyle of the owner, and local building codes.
4. Types of bathrooms in tiny houses
When it comes to including a bathroom in a tiny house, there are two main types to consider: wet bathrooms and dry bathrooms.
Wet bathrooms
A wet bathroom is one in which the entire bathroom space is designed to get wet. This means that the shower, toilet, and sink are all located in the same small area, and there’s no barrier between them and the rest of the bathroom. Wet bathrooms are incredibly efficient in their use of space, but they can be difficult to keep clean and can lead to issues with mold and mildew.
Dry bathrooms
A dry bathroom, on the other hand, is one in which the shower and toilet are separated from the sink and other bathroom fixtures. This can be accomplished by using a shower curtain or a physical wall to divide the space. Dry bathrooms are easier to keep clean than wet bathrooms, but they do require more space.
5. Bathroom layout considerations
When designing a bathroom for a tiny house, there are several layout considerations to keep in mind. First and foremost, you’ll need to think about how to maximize the use of space. This may mean opting for a wet bathroom, or it may mean using a folding or retractable shower to save space. Additionally, you’ll need to consider the placement of fixtures like the toilet and sink, as well as the type of toilet and shower you’ll use. It’s also important to consider accessibility – if you have mobility concerns, you may need to install grab bars or other assistive devices in your bathroom.
6. Size restrictions and building codes
When it comes to designing a tiny house bathroom, size restrictions and building codes are important considerations. Many cities and towns have specific regulations around the size and layout of bathrooms in homes, so it’s important to research local codes before beginning construction. Additionally, the smaller size of a tiny house means that you’ll need to be creative in your use of space – every inch counts.
7. Toilet options for tiny houses
There are several different toilet options to consider when designing a tiny house bathroom. The most common are:
- Composting toilets: These toilets use organic materials like sawdust to break down waste, which can then be safely disposed of. They don’t require any water or plumbing, making them a popular choice for tiny houses.
- Incinerating toilets: These toilets use heat to burn waste into ash, which can then be safely disposed of. They require a power source, but don’t require any plumbing.
- RV toilets: These toilets are designed for use in recreational vehicles and can be a good option for tiny houses as well. They require water and plumbing, but are often more comfortable to use than composting or incinerating toilets.
8. Shower options for tiny houses
When it comes to shower options for tiny houses, there are several different approaches you can take. Some popular options include:
- Wet bathrooms: As we mentioned earlier, wet bathrooms are an efficient use of space but can be difficult to keep clean.
- Retractable showers: These showers fold up against the wall when not in use, saving valuable space.
- Outdoor showers: If you live in a mild climate, an outdoor shower can be a great way to save space inside your tiny house.
9. Sink options for tiny houses
When it comes to sinks in tiny house bathrooms, you’ll want to choose a model that’s both functional and space-saving. Some popular options include:
- Wall-mounted sinks: These sinks are attached directly to the wall, saving valuable floor space.
- Corner sinks: If you’re tight on space, a corner sink can be a great way to maximize your use of available square footage.
- Pedestal sinks: These sinks are supported by a single column rather than a full cabinet, making them a great choice for tiny bathrooms.
10. Greywater and blackwater disposal
Proper disposal of greywater (wastewater from sinks, showers, and other non-toilet sources) and blackwater (wastewater from toilets) is an important consideration for any tiny house bathroom. Depending on local regulations, you may be able to dispose of greywater through a septic system or by using a greywater recycling system. Blackwater will typically need to be disposed of through a traditional septic system or a composting toilet.
11. Cost considerations
When designing a bathroom for your tiny house, cost is an important consideration. While a composting toilet may be cheaper than a traditional toilet, for example, it may not be the most comfortable or convenient option for you. Additionally, the cost of plumbing and electrical work can add up quickly, so it’s important to budget accordingly.
12. Pros and cons of having a bathroom in a tiny house
There are both pros and cons to having a bathroom in your tiny house. Some potential benefits include increased comfort and convenience, while some potential drawbacks include increased cost and maintenance requirements.
13. Maintenance and upkeep of tiny house bathrooms
Maintaining a tiny house bathroom requires some extra effort and attention to detail. Regular cleaning is essential to prevent the buildup of mold and mildew, and you may need to use specialized cleaning products to keep your composting toilet or greywater system functioning properly.
14. Conclusion
In conclusion, yes, it is possible to have a bathroom in a tiny house, but it requires careful planning and consideration of a number of factors, including space limitations, local building codes, and your own personal needs and preferences. By taking the time to research your options and plan your bathroom design carefully, you can create a comfortable and functional bathroom that meets your needs without taking up too much valuable space in your tiny house.
