Thank you for the details. I am a female and would like to build an outdoor shower in my backyard, using your instructions. I am very handy and have built many things in the past. The location I have chosen is about 40 feet away from the house and I'd like to know how to run the piping from the house to that spot - should I run it under the lawn? Also, I am not sure what a "tee" is? Also, If I purchase a free-standing outdoor shower, do I need to buy it with hot/cold water valves? Please give me a laymen explination of how you would go about doing this - I am only interested in the connection of the piper to the actual shower - nothing else.
