Budget
Direct swap of an existing dishwasher using existing water supply, drain, and electrical connections. No modifications needed — the installer disconnects the old unit, slides in the new one, and reconnects. Typical of a big-box store or appliance retailer installation add-on.
Mid-Range
Replacement where the supply line or drain hose needs to be rerouted or replaced, or a new braided stainless supply line and angle-stop valve are required. New mounting brackets and junction box cover may also be needed. Most homeowner upgrades fall into this range.
Premium
First-time installation in a kitchen that has never had a built-in dishwasher. Requires running a new hot water supply line, adding a drain connection at the sink drain or garbage disposal, and installing a dedicated 120V/15A or 20A electrical circuit. Permits required in many jurisdictions.
Material Options
Material prices below are national averages; availability in Las Vegas may shift costs slightly.
| Material | Cost/Unit | Best For |
|---|---|---|
| Braided Stainless Supply Line (3/8 in.) | $12-$25 each | Any replacement install; should be replaced any time the old supply line is rubber or shows crackingFlexible, kink-resistant, rated for 125 PSI — far more durable than the rubber lines that shipped with older dishwashers |
| Angle-Stop Shutoff Valve (3/8 in. compression) | $10-$30 each | Any installation where no dedicated shutoff exists, or where the existing valve is corroded or a gate-type valveProvides a dedicated water shutoff for the dishwasher without turning off the whole kitchen supply; required in most jurisdictions |
| Drain Air Gap (countertop or cabinet) | $8-$35 each | New installations, California kitchens, or any kitchen without an existing high-loop drain configurationPrevents backflow of sewage into the dishwasher if the drain gets clogged; required by plumbing code in California and several other states |
| Electrical Junction Box and Strain Relief | $8-$20 kit | First-time installations or whenever the existing junction box is absent or shows corrosionProvides a safe, code-compliant electrical connection point inside the dishwasher compartment; protects wire connections from moisture |
