Tiny House Plumbing Options

There are different ways you can bring water into your cozy tiny home. Both have their pros and cons.

Tiny House Plumbing Basics

There are two stages to completing your tiny house plumbing. We have the rough plumbing and the finish plumbing.

1. Rough Plumbing

This involves the installation and routing of pipes to the end destinations such as shower, bathroom sink, kitchen sink, toilet, and where other water appliances are located. Here, you have to install the water inlets, route the pipes and connect the drain pipes. This will enable water to flow well to the different sections where water is needed.

2. Finish Plumbing

This is the type of work that is done after the rough plumbing. Also, the interior work like the interior siding or drywall has to be completed before the finish plumbing can take place. This plumbing involves connecting the supply and drain lines to the plumbing appliances.

When the finish plumbing is completed, your tiny house will be connected to the water source using the water hose and every new plumbing connection have to be tested in case of any mistakes or leakage.

Tiny House Water Hookups

One of these methods is for a short term while the other longer term. Whatever method you choose, ensure that you insulate it properly.

  • Direct Connection
  • RV Water Inlet

Direct Connection

This method is more permanent for tiny houses that are not mobile. It is less prone to freezing, unlike the second method. Just ensure that you insulate the buried PEX line that connects to your house. This method is also cheap and neat on the outside but you will need more technical skill or knowledge to do it properly. And if you are moving, the connection needs to be cut.

RV Water Inlet

In this method, a spigot is used as your water source. It is good for tiny homes that are mobile and works well at most campgrounds. You will need a hose and use an RV water inlet to allow the entry of water into your tiny home. However, You have to make sure that the hose you will use doesn’t have chemicals that can contaminate your drinking water. Ensure you use a hose that is safe for drinking.

This method is easy to connect and disconnect unlike the former. It also has its disadvantages like being more prone to freezing, the hose and inlet can get damaged, it being more expensive and the hose connection may leak.

Each method has its pros and cons, you just have to choose a method that suits your needs.
