Maintain the dimensions

The average size of a tiny house bathroom is 25 to 50 square feet. Personal preferences may vary from person to person. If someone wants a bathtub, that measurement will almost certainly increase. 

Arrange Ventilation

Utilizing Back doors

The benefits of the cabinet’s back doors should be utilized to maintain things clean. PVC holders should be added to the backs of cabinet doors so that items that can be hung can be kept in that place.

Buying Shower caddies

Separate shower caddies should be kept in your bathroom. It’s because there could be several persons living in that tiny house, each with their shower products. Keeping all of those goods in the bathroom’s small space can be tough and messy. As a result, this helps keep your bathing space organized and allows individuals to get items when needed.

Tiny House Plumbing

The toilet is an essential part of the bathroom of any tiny house. There are a variety of options available in the toilet. Composting toilets, conventional toilets, regular flush toilets, RV flush toilets, incinerating toilets, and chemical toilets are all options in toilets.

Composting toilet 

Composting a toilet is a fantastic alternative for a tiny house because it doesn’t require plumbing and can flush sewage away. The wastes are composted on the site. A commercial composting toilet cuts down on the length of time it takes to dispose of waste. It is also environmentally friendly because it does not require any plumbing. 

However, they are pricey. There is also a different type of composting toilet. They’re known as bucket-style toilets, known for their endless storage capacity and ease of installation.

Standard flush toilet

A regular flush toilet can also be installed in a tiny home. However, a separate septic tank is required to hold the wastes, which is difficult to manage when the tiny house is moving.

RV flush toilet

RV flush toilets function similarly to normal flush toilets, but few differences. The usage of less water is one of the adjusted features. However, the tanks where the black water from this toilet will be stored occupy huge storage space. 

Incinerating toilet

One of the greatest solutions for your tiny house plumbing system is these toilets. Instead of flushing, the waste is burned using gas or electricity in incinerators. There is no need to worry about black water disposal because the garbage is burned.

Chemical toilet

Another option is chemical toilets, which require manual cleaning when they become full. However, the gross cleaning makes it less of an option for many.

Tiny house showers

The shower space is another important part of the bathroom. Showers are the ideal alternatives to bathtubs since they save a lot of water and easily fit into a small bathroom.

However, a tankless water heater should be connected to the shower for hot water supply control.

How to build

Getting water into the house

The simplest way to get water into the bathroom, toilet, or shower is to bypass the plumbing system entirely. So, to bring water into the house, you must carry it to the necessary places.
