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.
