Plumbing Your Tiny Home: Water In, Waste Out

Plumbing in a tiny home follows the same principles as conventional construction, just in a tighter package. The key challenge: routing pipes through minimal wall and floor cavities while maintaining proper slope on drains.

Water Supply System

Choosing Your Water Source

• City water connection: Most reliable. Use a standard hose bib with pressure regulator.
• Well water: Requires a pump and pressure tank.
• Water tank (mobile): 40-100 gallon fresh water tank for THOW builds.

Supply Line Materials

PEX tubing is the best choice for tiny homes:

• Flexible — routes through tight spaces easily
