Lower cost of living in Knoxville and the surrounding Tennessee region translates directly into more affordable contractor pricing. Because labor is 75% of a typical plumbing, this is the single biggest reason your project costs less here than in major metros.
Material costs
Lumber, fixtures, and finishes ship at similar prices nationally, so your material costs in Knoxville will be close to what someone pays in a major metro. The big savings in Knoxville come from installation labor — not the products themselves.
