How we installed an exterior shower

Well, we finally installed an exterior shower in the travel trailer. With 4 kids we've had this on our list, be it at the bottom of our list, for a while now. We kept putting it off until a recent don incident bumped it WAY up the list.

After our last trip I cam home and scoured Amazon for exterior showers and went completely based on ratings and whether it had Prime shipping. I ended up ordering the Phoenix shower and had it at the house in two days. My initial impression is that it's a cheap faucet in an OK enclosure...nothing special there. One thing to note is this shower didn't include any mounting hardware.

As for the install, it went about as expected. Cut hole in siding, install enclosure, and connect to water lines. Here's a list of tools and supplies I used for the install.

  • Phoenix Exterior Shower
  • 1 1/4" hex screws
  • Butyl tape
  • ProFlex RV sealant
  • 1/2" faucet flex hose (2 of them)
  • 1/2" Shark Bite Tee (2 of them)
  • 1/2" PEX tubing
  • 1/2" barb to 1/2" thread PEX fitting (2 of them)
  • 1/2' PEX crimps
  • PEX crimp tool
  • Tubing cutter
  • Pair of 7/8" wrenches
  • Saber Saw with fine metal blade
  • Drill with hex bit and drill bit

Now that we have the shower available I think we'll be using it more than we can imagine. There's really no limit on the mess the kids have been able to make, so I think this is one of the additions that will really make life easier.

  • I purchases a used trailer. with outside shower.. and the valve was split from freezing . not any hose.

    only leaked when using outside shower.. but leaked inside of wall.

    I use a compressor to force all water out of ALL lines/valves.( 40 psi ).. doing 1 valve at a time.

    If the back side of your external shower is unaccessable and in a cold space as mine is.. don't forget to figure out a way to drain it in cold weather.. I didn't and it froze breaking the fixture.. I have no idea why the low point drain wouldn't empty it even with the hose removed but it didn't..I think there is some type of check valve in the fixture?? Now I don't use it at all..


    That stinks! I blow out my lines and use antifreeze just to be on the safe side.

    Yeah, I think it'll be a huge help with the kids. The dog just lit a fire under me to actually do it.

    Low point drain isn't enough for winterizing. You should run RV antifreeze through all the lines. Or at least blow them out.

    I think you have to open the valves (hot and cold) for the water to drain out. Even if you take the hose off, water stays in there unless you open the valves. That's the way mine works anyway.
