How Much Does a Bathroom Addition Cost in Houston?
Adding a bathroom is one of the highest-value home improvements, especially going from 1 to 2 baths. In Houston, labor rates run $66–$123/hr — near the national average — which is factored into all estimates on this page.
The wide price range reflects major differences in project scope, materials, and the age of your home. A cosmetic refresh costs far less than a full renovation, and Houston's specific market conditions affect contractor pricing year-round.

| Plumbing location | $2,000–$8,000 | High |
| Square footage added | Scales linearly | High |
| Permits | $500–$2,000 | Medium |
| Labor | $70–$130/hr | High |
