It can cost anywhere from $500 to $5000 to have a new house properly plumbed. The amount of money you'll spend depends on the size and layout of your home, as well as the quality of plumbing materials and workmanship. For instance, if you have a lot of custom features or if the plumbing needs to be installed in an existing wall, it will likely be more expensive than if you just need standard fixtures installed in an open space. If you're doing some of the work yourself, be sure to account for the cost of materials and tools. You'll also need to factor in time spent on the project, as plumbing can be a complex task that takes a fair amount of experience and skill.

It depends on the size of the house, the number of bathrooms, and other factors. Generally speaking, it costs between $1,500 and $3,000 to install plumbing in a new home.
