A typical dishwasher installation takes 1.5 to 3 hours. Standard swap-outs with existing electrical and plumbing are on the shorter end. Installs requiring new dedicated circuits, supply lines, or drain modifications can extend to 4 hours. We schedule installs as 2- to 3-hour appointments to allow for testing.
What affects timing
- Standard swap-out — 1.5–2.5 hours
- First-time install needing new lines — 3–4 hours
- Granite countertop with side-mount brackets — adds 15–30 min
- Hardwired vs. cord-and-plug — minor difference
- Adding water-supply braided hose and shutoff — 30 min
