New dishwasher delivery sitting in your kitchen, old unit that needs to go, or a first-time installation where no dishwasher existed before — Royalty Plumbing handles the full plumbing scope, hauls away the old unit, and leaves your kitchen clean. We install all brands across the Las Vegas Valley.
Dishwasher installation in Las Vegas typically costs between $150 and $350 in labor, not including the dishwasher itself. A standard like-for-like replacement — removing the old unit, connecting the new one to the existing supply line, drain connection, and electrical, and hauling away the old dishwasher — typically runs $150 to $225. Installations where the supply line, drain hose, or electrical connection needs to be updated run $200 to $300. First-time installations where no dishwasher previously existed — requiring a new supply line tap, new drain connection, and sometimes electrical work — run $250 to $400 for the plumbing scope. If new electrical is needed for a first-time install, an electrician is required for that portion and is a separate cost. We handle the full plumbing side and coordinate timing with the electrician if needed.
The price depends on several factors:

Call (702) 908-0953Las Vegas hard water at 280 to 290 PPM is harder on dishwashers than on almost any other appliance in the home. Mineral scale deposits on the spray arms, clogs the filter, etches glassware, and builds up inside the pump and heating element over time. These are the signs that replacement makes more sense than another repair:
We open the cabinet under the sink, check the condition of the dishwasher supply line and shutoff valve, inspect the drain connection and air gap if present, and confirm the electrical connection is accessible and appropriately rated for the new unit. In Las Vegas, dishwasher supply line shutoff valves and braided supply lines on existing installations are commonly corroded or mineral-encrusted — we report what we find and quote any needed updates before starting the swap.
We shut off the supply, disconnect the supply line, drain hose, and electrical connection, and slide out the old dishwasher. We include haul-away of the old unit as part of every standard installation — it goes with us when we leave. We clean the dishwasher cavity before installing the new unit.
We slide in the new dishwasher, connect the supply line to the shutoff valve under the sink, route and connect the drain hose through the air gap or directly to the garbage disposal drain inlet or drain tailpiece depending on your existing configuration, and reconnect the electrical. We level the unit using the adjustable feet, verify the door seals cleanly against the tub gasket, and secure the mounting brackets to the underside of the countertop per manufacturer instructions. For first-time installations where no dishwasher previously existed, we run the new supply line from the nearest hot water shutoff and create the drain connection at the sink drain or disposal.
We run a short test cycle, check all connections under the sink for drips during the fill cycle, verify the drain line is clearing completely at the end of the cycle, confirm the door latch and gasket are seating correctly, and clean up the kitchen before we leave. You see the dishwasher complete a cycle before we pack up.
Like-for-Like Dishwasher Replacement
The most common call we receive. Your old dishwasher is being replaced with a new unit of the same configuration — same space, same supply and drain connections, same electrical. We remove the old unit, install the new one, connect everything to the existing supply, drain, and electrical, haul away the old dishwasher, and run a test cycle. This is the most straightforward installation and is typically completed in under two hours.
Best for: Standard 24-inch dishwasher replacements where the new unit matches the existing opening and connection points.
Typical labor cost: $150 to $225.
Brand or Model Upgrade With Connection Updates
You are upgrading from a basic builder-grade unit to a higher-end model — Bosch, KitchenAid, Miele, or a similar premium brand — and the new unit has different connection requirements or the existing supply line, shutoff valve, or drain hose needs to be updated. Premium dishwashers often require a specific drain hose routing and may have different leveling and mounting requirements than the unit being replaced. We handle all connection updates as part of the installation.
Best for: Upgrading to a premium brand, units where the existing supply line or drain hose is aged or not compatible with the new model, and any installation where the existing connection hardware needs to be brought up to current condition.
Typical labor cost: $200 to $300 depending on what connections need updating.
First-Time Dishwasher Installation
Your kitchen has never had a dishwasher and you are adding one for the first time. This requires running a new hot water supply line from the nearest connection point under the sink, creating a drain connection at the sink drain tailpiece or garbage disposal inlet, and confirming the electrical supply is accessible and appropriately rated. The plumbing scope is the part we handle. If a new dedicated 120V 20-amp circuit is needed and does not already exist at the dishwasher location, an electrician is required for that portion before we connect the unit. We can coordinate timing with an electrician and confirm what the electrical scope requires before scheduling.
Best for: kitchen plumbing being upgraded from hand-washing to dishwasher-equipped, new kitchen buildouts, and ADU or guest suite kitchens being outfitted for the first time.
Typical labor cost: $250 to $400 for the plumbing scope, not including any electrical work.
Remodel Disconnect and Reconnect
Your kitchen is being remodeled — countertops, cabinets, or both are being replaced — and the dishwasher needs to be disconnected before the work, stored or reinstalled in the same location, and reconnected after. We coordinate timing with your remodel contractor, disconnect the unit cleanly before cabinets are removed, and reconnect it after the new countertop is set. If a new dishwasher is going in as part of the remodel, we handle the full installation at the reconnect stage.
Best for: Kitchen remodels involving sink installation where the existing dishwasher is being retained or where a new unit is going in as part of the remodel scope.
Typical labor cost: $100 to $175 for a disconnect-only or reconnect-only visit. Full replacement during a remodel follows the standard installation rate.

We provide exact pricing before any work begins. Here is what determines where your installation falls in the range:
A straight swap of one dishwasher for another at the same location with working existing connections is the simplest and least expensive installation. First-time installations requiring new supply lines, new drain connections, or coordination with an electrician involve more scope and more cost.
The dishwasher supply line connects from the shutoff valve under the sink to the dishwasher's water inlet valve. In Las Vegas, these lines and valves are frequently corroded or mineral-encrusted on existing installations. We replace them as a standard precaution on any installation where the existing line is more than 5 to 7 years old — because a supply line failure inside the dishwasher cavity floods the cabinet and subfloor with no visible warning. We quote this before proceeding.
The dishwasher drain hose connects either through an air gap device on the countertop or directly to the garbage disposal installation inlet or sink drain tailpiece. If the existing drain connection routing does not meet current code or the new dishwasher has a different drain hose length or diameter than the old unit, we reconfigure the connection. Air gap installation, if not already present, adds to the labor time.
Nevada plumbing code requires an air gap device on dishwasher drain connections in new installations to prevent drain water from backflowing into the dishwasher. Many older Las Vegas homes have dishwashers installed without an air gap. If your installation requires an air gap and one does not exist, we install it. The air gap mounts through the countertop or sink deck next to the faucet. Budget $50 to $100 for parts and labor to add an air gap if one is not already present.
Dishwashers mount to the underside of the countertop using brackets and must be leveled precisely so the door seals correctly. Some Las Vegas kitchen cabinets — particularly older custom or builder-grade installations — have clearance issues that require shimming or cabinet floor modification before the unit can be fully seated. We handle minor clearance adjustments as part of the installation. Significant cabinet modification is quoted separately.
We include haul-away of the old dishwasher in every standard replacement installation. No separate haul-away charge. The old unit goes with us when we leave.
Hard Water Note for Las Vegas: Regardless of the dishwasher brand you choose, we recommend filling the rinse aid dispenser before the first cycle and using a citric acid-based dishwasher cleaner monthly. Las Vegas water at 280 to 290 PPM will deposit mineral scale on the spray arms and filter within the first few weeks of operation without rinse aid. This is not a dishwasher defect — it is a Las Vegas water condition that every homeowner needs to account for.

"Finding a trusted plumber in the Las Vegas area can be hard to come by. When you have Anthony at Royalty Plumbing, you. Ever have to worry. He’s honest, funny and does great work."

"The bathroom sink started to leak underneath. I tried everything that I know how to do to fix it, to no avail. I called Royalty Plumbing and they were able to have technician here the next day. It was a simple fix but unless you have that knowledge, you just wouldn’t know how to do it. The price was good, and the service man was friendly and quick! No mess left behind! This sink was installed about a year ago by another “plumber,” who didn’t do a very good job."
