Living in a tiny house has its own perks. It is efficient and budget-friendly, and one of the best parts is that you can take your entire house with you while traveling if it’s a mobile house. Here is a detailed article on how to build a toilet in your tiny home!

However, the main downside to tiny homes is that there is a space crunch. Due to this, you will often find yourself looking for innovative ways to make the most out of the space you have. You might try getting rid of your belongings, or even moving certain things outside, just to save up space.

For instance, for the most part, you can try moving your kitchen to the outdoors if there is not enough space for it at your place. Since cooking uses fire and causes a lot of smoke, in some cases, it might even be better if you do your cooking outside your home, but what about a toilet?

No matter how tiny your house is, it is better to have your toilet inside your home. After all, it keeps your surroundings hygienic and keeps you safe too. Hence, we have curated some small home toilet ideas that you can use for your tiny house.

Why You Need to Build a Toilet in Your Tiny Home

There are numerous benefits to building a toilet in your tiny home. And, if you are worried about the different aspects of it, well, we’re are here to tell you that you have nothing to worry about. 

Here are some benefits to having a toilet in your tiny house:

Build A Toilet In Your Tiny Home: Its cost-efficient

If one of the concerns you have about having a tiny house toilet is the cost, you can throw your worries out the window. Compared to the convenience it gives, the cost does not add up to a lot. 

Nowadays, compostable toilets are not what they used to be, and you can get high-quality toilets for cheap. These toilets promise longevity and can last you a lifetime if cared for properly. And, if you are comfortable buying something more expensive, it’ll make for a great investment. This is because, once you buy a toilet for your tiny house, that’s pretty much all you will need to spend. These toilets are durable and you will barely need to spend money on maintenance.

However, if buying is an option that is difficult to consider, you can find tutorials on how to DIY them at a way cheaper price too!

Build A Toilet In Your Tiny Home: Very convenient 

Something that you will get as an advantage of having a tiny house toilet is the convenience. 

Since you will have an in-house toilet, you will not have to travel to the nearest traditional toilet, which can be an issue if you are traveling, and you will not have to go outside either. This will maximize your safety, especially if you are living away from the urbanization, or near the woods, as it’ll keep you safe from animal attacks.

Build A Toilet In Your Tiny Home: Takes up less space

Another benefit you will experience is that it will take up very little space. This is very important if you have a lot of belongings or if you are living with companions. 

Having a toilet in the corner of the house will not make your house look smaller, but still, give you the benefits of having a toilet. 

Additionally, there are smaller sizes of toilets available on the market, in case you require even more space in your house.

Build A Toilet In Your Tiny Home: Maintenance is easy

As we have previously mentioned, toilets that are designed specifically for tiny houses are durable and can last you a lifetime if cared for properly, however, the maintenance is not that difficult. 

Most of the tiny house toilets have compartments to store wastes, and only need to be emptied out once every few weeks depending on how many people are using them. Apart from that, just giving the waste bins a quick hose down once in a while can clean it pretty well.

Different Kinds of Tiny House Toilet

One of the best parts of having a tiny house toilet is that you have the option of choosing the kind of toilet that will suit your lifestyle the best. Unlike traditional toilets, toilets designed for tiny houses function in numerous ways, and all of them have their own pros and cons.

The types of tiny house toilets include:

Traditional Toilets

Traditional flushing toilets are what everyone uses in their regular-sized homes. However, using them at a tiny house can be difficult but not impossible. A traditional toilet is required to be hooked up to a water supply and sewage or septic, and if they are available for you, you can use these toilets.

But, if you are at a place where you do not have access to a water supply or sewage, which is usually the case for mobile houses, it might be in your best interest to use a different type of toilet.

Macerating Toilets

Macerating Toilets, which are quite similar to traditional toilets except for the fact that they have an additional unit that grinds up waste can be very beneficial. Macerating toilets work by using minimal amounts of water to liquefy wastes and pump them out or store them away until disposed of.

These toilets make for a great option as a tiny house toilet if you are living on a foundation that has plumbing and electricity since they require both. However, if you are planning on living in a mobile house or an RV, we would not recommend getting them.

Compost Toilets 

Compost toilets are the most common type of toilets used in small houses. They have self-contained bins where wastes are stored until you dispose of them. This is a great option as it keeps the solid and liquid wastes separate and uses a natural process of decomposing them to make usable composts like fertilizer. 

Something to remember for compost toilets is that they eliminate foul odor, so that is definitely not something you should lose sleep over.  

Biogas Digester Toilets

Biogas Digester toilets break down waste with the help of anaerobic digestion that is performed by bacteria. They are a system of tanks that are filled with bacteria colonies, and these bacteria eat the waste. 

These toilets do not require any plumbing or electricity and are quite beneficial in multiple ways. The main benefit they give you is that the bacteria break down the human waste to produce methane and carbon dioxide which can be used as cooking gas and organic fertilizer. 

Incinerator Toilets

Incinerator toilets, although quite expensive, make for great investments which can be considered as small home toilet ideas. This type of toilet burns wastes and stores them in an ash deposit which can be disposed of later. 

A benefit you have with this is that you won’t have to empty it out or clean it as often, and the wastes themselves won’t produce any smell. However, the process of burning can produce an unpleasant odor, and also they take a significant amount of energy to run.

Dry Flush Toilets

Dry flushing toilets make for a great option as they do not require much maintenance or plumbing. These toilets work by using cartridges that are filled with silver liners. These liners, when flushed, wrap the wastes tightly to avoid odors from escaping, and once the liners are full, you can empty them and replace the cartridges.

An advantage you get with dry flush toilets, compared to the other kinds, is that they are really cheap to install, and you don’t really have to worry about maintenance costs other than the liners. 

Chemical Toilets 

Chemical toilets are excellent small home toilet ideas for those who are traveling in their mobile houses. They are cheap and convenient, and the wastes can be disposed of at waste takes.

However, if you are at your property, that can serve as a problem. You will have to plan how to dispose of your weekly waste in these situations. Not to mention, the chemicals used to break down the waste are quite bad for the environment.

RV Travel Toilets

RV travel toilets also make exceptional small home toilet ideas that are eco-friendly for those who have mobile houses. Unlike the previous options, however, they use water to flush the waste. But you don’t really have to worry too much about that since it uses minimal amounts of water per flush

These toilets have a holding tank that needs to be drained when it fills up and cleaned out from time to time. It’s cost-effective and perfect for anyone on a budget as well.

Homemade Compost Toilets

Homemade Compost Toilets are probably the cheapest tiny house toilets out there. Not to mention, they are the easiest to maintain on the list. For these toilets, you will need a bucket and sawdust or peat moss, which you will have to place at the bottom of the bucket. Place a foam seat or a traditional toilet seat on it, and you’re good to go! Just empty the bin as needed, and you don’t have to do much other than that.

However, these types of toilets have a huge disadvantage, which is the odor. Since it does not have ventilation, the odor can be a problem, however, there are solutions to it too. You could either use pine shaving to mask the odor or get a urine diverter to help with the smell. 

How to Build a Toilet in Your Tiny Home

Weigh your options

When looking for small home toilet ideas, for your tiny house, you will first need to weigh your options. Look at the pros and cons and the prices of building each of the types of toilets and start considering from there. 

Most tiny house toilets are quite cheap but if you are looking at compost toilet options, then that can get a little expensive depending on the brand. However, compost toilets are still worth the money if you are keen on gardening since you can get free compost that will last you a while for a reasonable price.

Measure the space

Next, you will need to measure the space you want the toilet to go in. Most toilets are built to be about the same size, but there are some toilets that come in various sizes. Get one that is comfortable but does not take up too much space, after all, you will need space to stand and place your sink.

Consider Eco-friendly options

One thing that is important to consider when looking for small home toilet ideas is their eco-friendliness. If you can use compost or incinerated ashes for gardening, go for it! You don’t want to be disposing of wastes in non-biodegradable cartridges and liners just anywhere. Choose an option that is both convenient for you and beneficial for the environment.

Check availability of water, electricity, and hygiene 

If you want to use water to flush out the waste, or if you want to purchase a high-tech incinerating toilet, we recommend looking into your water and electricity supply. 

If you do not have a source of supply, you can consider buying a tank of water or some solar-powered batteries to help you with that. You can also install a septic tank if you want everything to stay extra hygienic.

Create a checklist and get to work

Create a checklist of all the small home toilet ideas that you have to consider and do before building a small home toilet.

Once that is done, it’s time to get to work. Purchase the toilet you desire and start building it according to the manuals. If you are not very good at handy work, you can also hire a professional. Although that will cost more, it is better to let a pro do it than mess up while trying to forcefully do it yourself.


Having a toilet in your small home can benefit you in numerous ways. They keep everything hygienic for reasonable prices and are not unrealistically hard to build. Additionally, you have multiple options to choose from, and purchase one that suits your lifestyle the best.

So, if you are moving to a tiny house, take some small home toilet ideas and build one for yourself right away!
