What drives where your project lands
- Doing both together — combining kitchen and bath into one project shares mobilization and permit costs vs. doing them separately.
- Cabinetry & tile — the biggest cost swing across both spaces.
- Layout changes — moving plumbing or walls in either space adds cost.
- Finish level — builder-grade to fully custom across both rooms.
- Home age — older King County homes may need electrical or plumbing updates once opened.
