My wife and I plan on buying around 2 to 5 acers of land in the phoenix area. We are going to build a home that will only be 570 square feet with 1 bathroom. Our kitchen will not have a garbage disposal or a dish washer. It will only have a sink. About how much will it cost to get plumbing all from scratch. After looking around, I learned — Call plumber to get estimate for plumbing cost. Tell him what kind of plumbing you want. As there is no more work so it will not take much cost for plumbing.
