In Fort Collins, adding a bathroom generally runs about $4,000 to $12,000 for a half bath (powder room), $10,000 to $50,000 for a full bathroom, and $22,000 to $90,000 for a primary bathroom. Converting existing space, like part of a bedroom or a closet, is usually cheaper at $5,000 to $25,000, while building out new square footage costs more. The biggest cost drivers are the plumbing run, the bathroom type, and whether you bump out or convert.

A half bath (powder room) typically runs $4,000 to $12,000, a full bathroom $10,000 to $50,000, and a primary bathroom $22,000 to $90,000. Converting existing space is usually cheaper than building out new square footage.
Converting existing space, like part of a bedroom, a closet or a basement, is usually cheaper at about $5,000 to $25,000, because you avoid foundation and exterior work. Building out new square footage costs more.
The plumbing run is the big one, along with the bathroom type and finish level. A primary bath far from existing plumbing, with high-end tile and glass, sits at the top of the range.
Yes. A bathroom addition needs permits for the plumbing, electrical and any structural work, and the permitting phase takes time. We manage that process for you.
