Tiny House Rough In Plumbing

I took a week off of building to assemble a new scooter I ordered. Next was to finish up the plumbing and insulation.

First thing I did was to cut a hole where I wanted the drain:

Tiny House Drain Hole

Here’s the drain pipe assembly:

I attached the drain pipe to the 2″x4″ with a strap for stability:

I fit the drain pipe into the hole again:

And then I used another strap to attach the rest under the house:

I ran some PEX tubing through the walls and put in garden hose sized male and female adapters with 1/4″ screw clamps:

For the water to enter the tiny house, I used a garden hose splitter. The left side goes to the PEX tubing which will go to the shower which is a propane powered portable hot water heater I got on Amazon. The right side has an attachment that will go to the line to the sink. I sealed all the threads with sealant for that purpose.

… and bolted the assembly to some blocking I added:

Here’s what it looks like on the outside (after I sealed it up with caulk):

Then I closed both the valves on the splitter and hooked up a garden hose. Water flows through and no leaks!

I originally was going to run a couple of different pipes and attachments together for the propane line for the shower. When I sized it up, turns out the included hose is long enough to reach by itself:

And this is where the propane tank will sit on the hitch:

And then I went back and sealed up the opening:

Next, I’m insulating the walls and putting in the bathroom walls.

    You might want to leave that “plumbing” accessible behind access doors or something. Clamps and garden hose connections seem destined for leaks down the years, and it may save a lot of wall-ripping to have that assembly easily available for repairs.

    Yes, I was planning to put a panel in the wall in front of the main connection. The rest will be out of the wall anyway. I’ll be sure and show what I end up with.

    LOVE this house! Where does the used shower water go? just into the yard?

    Hazel, it can go into the yard or it can be collected and used for irrigation somewhere more convenient.
