Understanding Tiny House Plumbing Fundamentals

Tiny houses have unique plumbing systems. Tiny house toilets and tiny house showers are compact and efficient, but they differ from standard residential plumbing. The hot water heater in a tiny home trailer must also be sized and installed considering the limited space.

Basic Plumbing Components

Every tiny house plumbing system includes several key parts. There’s a water source for the rough plumbing, which could be a hookup or tank, and a hole for the tiny house shower before the finish plumbing is installed. Pipes carry water to fixtures like sinks and showers. Waste needs to exit through a drainage system. This water line might connect to the sewer drain or go into a holding tank during the rough plumbing phase before finish plumbing is completed.

Differences From Traditional Plumbing

Tiny house plumbing stands apart in several ways. Space is limited, so everything, including the tank and vent, is smaller and more compact, with no room for a hole or trap. Many tiny homes are mobile, which means their plumbing systems must adhere to the plumbing code, withstand movement, and be flexible enough for different hookups, including options for tank storage and hole placement.

There’s also an emphasis on sustainability. Tiny homeowners often use less water and prefer eco-friendly options like composting toilets, ensuring they meet plumbing code requirements for drain, vent, and trap systems.

Materials and Tools Needed

Working on tiny house plumbing requires specific materials, like pex pipes, and tools for hot water systems, drains, and proper ventilation. You’ll need pipes, fittings, valves, and faucets that comply with the plumbing code and are designed for small spaces. Ensure the use of pex tubing where appropriate, and incorporate the necessary drain and vent features. Tools like pipe cutters, wrenches, and sealant are essential for PEX installation, drain maintenance, vent adjustments, and hot water system repairs.

Some common materials include:

• PEX piping: Flexible and easy to install.
