Are you planning to move into a tiny home or a camper van?

Well, there is so much that comes with living in a tiny home.

First, you’ll need to downsize your lifestyle as you have limited space to play with.

And secondly, you’ll need to figure out how you’ll shower and handle other businesses, which is the tricky part.

For many people just learning about the tiny lifestyle and tiny homes in general, there is always the question of how to fit in a bathroom/toilet combo in a tiny home.

And to be honest, this can be pretty challenging when you live in a small space, mainly because you can’t seem to use the regular toilets you have in traditional homes.

Read on as we take you through the details.

Portable toilet stored in a shower

If you’re looking to have a bathroom combo in your tiny home, you won’t be disappointed to have a shower stall and a portable toilet to go with it.

Typically, the portable toilet is stored inside your shower stall for easy access.

This type of design saves you a lot of headaches.

To start with, you’ll have a built-in shower stall.

Once that’s done, you can simply get a portable toilet you can store in the stall.

People who have this type of bathroom toilet combo will typically take out the portable toilet when they have their bath.

Toilet combo and shower wet bath

Solving your tiny house toilet problems will involve thinking outside the box.

Talking about that, you can opt for a toilet combo and shower wet bath.

What’s unique about wet baths is that they have a built-in shower, toilet, and sink.

Some top options available on the market include a towel holder and a mirror.

Designed to have wet surfaces, wet baths are the best option for tiny house owners looking to enjoy all the comforts of a home in a tiny house.

Pull out shower with portable toilet

This is perhaps the most brilliant shower toilet combo we have come across.

This bathroom option involves having a pull-out shower along with a portable toilet.

To be precise, the pull-out shower is crafted out of a utility sink and placed in a pull-out drawer nicely constructed in your home.

When you aren’t using it, you simply have to put it back into the cabinet.

On the flip side, you simply have to take it out of the cabinet and attach the portable shower head to a nearby tap to take your bath.

For privacy, this bathroom option comes with a shower curtain which is excellent for privacy and water control.

To complete the combo, you can store a portable toilet near the pull-out shower.


  • Thanks to its space-saving design, this toilet option helps maximize the limited space in your tiny home as you can nicely tuck everything away in a drawer when not in use.
  • It is a lot cheaper than installing a comprehensive shower stall or wet bath.
  • The weight is pretty manageable, so you have nothing to worry about.


  • You have limited privacy with this option. Even though it comes with a makeshift curtain for privacy, you don’t get all the privacy you deserve.
  • It’s not very comfortable. With this option, all you have is a shower sink. So there is not a lot of room to move around.
  • It is a bit technical. And since it is kind of a makeshift bathroom combo, you’ll need to think outside the box to ensure it fits in your home.
  • Shower and toilet are separate: While you have to store the shower in a pull-out cabinet, you need to have the portable toilet close by too. Although the design may improve flexibility, it doesn’t really make for a decent bathroom.

No shower and toilet option

If you live in a tiny house on wheels and plan to journey into the wild, you’ll have to rely on the great outdoors for your toilet and shower needs.

For those looking to cut costs, this is perhaps the most affordable option in the books.

While, on the one hand, it saves you cost, it also helps you save a lot of space in your tiny home.

If you decide to go this route, we want to encourage you to respect the environment and keep it clean.

We have come across scenes where people mess the whole place up with toilet paper, and honestly, this isn’t fair to the environment.

Similarly, it’s best to use natural soapy water when showering in the wild.

This type of soap does not cause damage to the environment.


  • It is among the cheapest option in the books. With this option, you won’t spend so much on maintaining your tiny home.
  • Having this option means you can seamlessly travel off track without bothering too much about how you’re going to dispose of waste.
  • It saves you quite some space. And yes, you don’t have to worry about storing your portable toilet.


  • Inconvenient: Trust us when we say it can be pretty inconvenient to go outdoors to handle your bathroom and toilet needs. Not just that, it can also be pretty uncomfortable when it is raining or snowing.
  • Opting for this option means you’d have to shower less frequently. So overall, it would affect your cleanliness.

Setting up a shower stall to accommodate a portable toilet: How to go about it

If you want a nice shower along with a portable toilet, you’ll need to have ample space in your tiny home to build a shower stall.

Also, you need to shop for the perfect portable toilet that fits nicely in the shower.

While some tiny houses on wheels come with pre-installed shower stalls, you may need to install one if your tiny home doesn’t already have a shower stall.

Here is how to set up a shower stall that can house a portable toilet.

  • Start by creating a frame for your shower. To do this, you’ll need to measure the space you have to play with. Once that’s done, you’ll need to build a frame for the shower. If you can’t do that on your own, we suggest you get a professional to do it.
  • Make room for lighting: When setting up the frame, please make room for light sources, as you don’t want to have your bath in the dark.
  • Include shower walls: For the shower walls, we suggest you use waterproof panels to create that. Also, ensure you layer that over the wood. You can follow this up by sealing up any gaps with silicon. This will prevent water from escaping and damaging the foundations of your shower frame.
  • Add a shower pan to the base: Having a shower pan in your stall is incredibly important, especially considering that it helps collect water from the shower and channel it to the drain. More so, it also helps protect the shower floor and foundation of your home. When shopping for a shower stall, we strongly recommend going for one made from thermoformed ABS.
  • Install plumbing: Once you have your shower pan installed, you can connect it to your home’s plumbing. Doing this will help channel drained water to the right place. Again, if you’re finding it hard getting this done or you don’t want to get your hands dirty, we suggest you seek professional help.
  • Install a shower head: While connecting your plumbing, another thing you want to do is install the showerhead. You can browse through Amazon to find the perfect shower head for your bathroom.
  • Install shower door and curtain: If you want to have some privacy while showering or using the toilet, we suggest you install a shower door. Also, having a curtain will provide extra privacy.

How to install a wet bath in a tiny home

If your tiny home doesn’t already have a wet bathroom installed, we will show you some tips to easily have one installed.

Though it can be pretty challenging if you plan to do it yourself, you can always consult a professional if you get stuck.

Here are some critical steps to follow to install a wet bath in a tiny home.

  • Know the size of your wet bath and build the frame: While doing this, please take into cognizance all the space you’ll need, including the shower area, toilet area, and sink.
  • Install waterproof walls: Since you’ll be dealing with a lot of water, we suggest you install waterproof walls. With this in place, you can ensure your home is protected from water damage.
  • Install shower pan and showerhead
  • Install your preferred toilet system: Most wet baths we have come across feature a cassette toilet. For those new to all this, this type of toilet comes with fixed, portable tanks. Thanks to its design, it makes cleaning super easy.
  • Install a waterproof door: Having this will protect your home from any type of rust or water damage.

Before deciding which portable toilet option works best for you, its important to factor in these things.


Price is an essential factor you want to consider before buying any shower toilet combo.

For instance, composting toilets are a tad expensive and cost between $500 to $1000.

Size/weight and capacity

There is no doubt that the size of your portable toilet is important, especially given the limited space in your tiny house.

And as you’ll agree, with the limited space available in your home, you should be opting for something that doesn’t take up too much space.

As per capacity, it’s important you consider how frequently you want to dump the waste.

Though this may sound a bit odd, we think it’s best to opt for a toilet with a smaller capacity waste tank.

The reason for this is that it makes it easy to keep your home fresh.

With a larger waste tank, things can get nasty as you may be forced to keep using the toilet until it fills up.

Cleaning and maintenance

If you live in a tiny house, you’ll agree that keeping your space clean is super important.

For this purpose, we recommend getting a chemical toilet as it is designed to help manage the odor generated.

Not just chemicals, you can also use peat moss or kitty litter to keep things pretty clean.

When opting for a chemical or portable toilet, we strongly recommend going for toilets that are easy to clean.

To keep the whole place smelling fresh, we suggest using natural cleaners like lemon and vinegar juice.

Quick reminder: Never use bleach when cleaning out your toilet.

This is because mixing up with ammonia urine will trigger a harmful chemical reaction.
