Garbage Disposal Installation in Las Vegas, NV
New disposal sitting under your sink, existing unit that finally gave out, or adding a disposal to a kitchen that has never had one — Royalty Plumbing installs all brands and sizes across the Las Vegas Valley. We supply and install, or install yours. Same-day availability most days.
What Does Garbage Disposal Installation Cost in Las Vegas?
Garbage disposal installation in Las Vegas typically costs between $200 and $450 all-in, including the unit and labor. If you supply the disposal, labor to install it runs $100 to $175 for a standard like-for-like swap at an existing location. If we supply and install, the total depends on the unit size and brand — a basic 1/2 HP InSinkErator Badger installed runs $200 to $275, a mid-range 3/4 HP unit runs $275 to $375, and a premium 1 HP Evolution or comparable model runs $350 to $475. First-time installations where no disposal previously existed require a new drain connection and occasionally a new electrical outlet, which adds to the total scope.
The price depends on several factors:
- Whether we supply the unit or you provide your own
- Horsepower and model tier — larger motors cost more but last significantly longer in Las Vegas hard water conditions
- Like-for-like replacement versus first-time installation
- Condition of the existing sink flange, mounting assembly, and drain connection
- Whether a dishwasher drain connection needs to be maintained or added at the disposal inlet
- Electrical outlet availability under the sink — most disposals plug into a switched outlet; if one does not exist, an electrician is needed for that portion

Signs It Is Time to Replace Your Garbage Disposal in Las Vegas
Las Vegas hard water at 280 to 290 PPM deposits mineral scale inside disposal grinding chambers, accelerates corrosion on the mounting assembly and drain connections, and shortens motor life compared to soft-water markets. Average disposal lifespan in Las Vegas is 8 to 10 years — slightly shorter than the national average. These are the signs that replacement makes more sense than another garbage disposal repair:
- Disposal hums when switched on but the grinding plate does not spin — the motor is receiving power but the impeller plate is seized, usually from a jammed object or mineral-fused components. If the reset button does not clear it and manual Allen wrench rotation at the base does not free it, the motor is likely failed and replacement is the answer
- Persistent leaks from the sink flange at the top of the unit — the putty or gasket seal between the sink flange and the basin has failed. On units more than 8 years old, this repair cost approaches the cost of a new unit. On newer units, reseating the flange is straightforward
- Leaking from the side of the unit at the discharge outlet — the gasket at the dishwasher inlet or drain discharge connection has failed. Gasket replacement is inexpensive on newer units. On aging units, this is often the first of several failures
- Leaking from the bottom of the motor housing — an internal seal has failed inside the motor. This is not repairable — the unit must be replaced
- Frequent jams on normal food scraps — a disposal that jams on eggshells, vegetable trimmings, or normal food debris has either an undersized motor for your household's use or a grinding plate that is worn down from years of mineral scale contact. Both conditions indicate replacement
- Persistent drain odor that cleaning does not resolve — mineral scale and food debris have built up inside the grinding chamber walls in layers that cleaning cannot reach. Common in units over 8 years old in Las Vegas
- Unit is noticeably louder than it used to be — worn grinding components and loose internal parts create vibration and noise. A disposal that was quiet when new and is now noticeably loud has internal wear that will progress to failure
- The unit is more than 10 years old — past the expected service life for Las Vegas conditions regardless of apparent function
How Royalty Plumbing Handles Garbage Disposal Installation in Las Vegas
-
Step 1 — Assess the Existing Setup
We check the condition of the sink flange and mounting assembly, inspect the drain connection and dishwasher inlet if present, and verify an electrical outlet is accessible under the sink. On units where the sink flange is being reused, we assess whether it is in sound condition or needs replacement with the new unit. On first-time installations where no disposal previously existed, we determine the drain rough-in configuration and confirm electrical availability before quoting the full scope.
-
Step 2 — Remove the Old Unit
We disconnect the power, remove the drain connection and dishwasher drain inlet if present, and unmount the existing disposal from the sink flange. If the sink flange is being replaced, we clear the old putty seal and prepare the sink basin for the new flange. The old unit is available for homeowner disposal or we can haul it away — let us know your preference.
-
Step 3 — Install and Connect the New Unit
We mount the new sink flange with plumber's putty, seat the mounting assembly, and hang and lock the new disposal. We connect the drain discharge to the p-trap, reconnect the dishwasher drain inlet if applicable, and plug the unit into the switched outlet under the sink. We confirm the reset button is accessible and that the disposal rotates freely before restoring power.
-
Step 4 — Test and Confirm
We run cold water, switch the disposal on, confirm it spins freely and quietly, verify no leaks at the flange, discharge connection, or dishwasher inlet, and clean up the work area completely. We walk you through the reset button location and the Allen wrench port at the base — the two things every Las Vegas homeowner should know how to use before they need them.
What Size Garbage Disposal Does Your Las Vegas Home Need?
Horsepower is the most important specification when choosing a garbage disposal for a Las Vegas home. Our hard water deposits mineral scale inside grinding chambers over time, and a motor with adequate power handles that added resistance without laboring. An undersized disposal in Las Vegas hard water conditions jams more frequently, clears food waste less completely, and fails earlier than one correctly sized for the household's use pattern.
1/3 HP — Basic Single-Person or Light-Use Only
A 1/3 HP disposal is the
entry-level option. It handles soft food scraps in a single-person household with minimal cooking. In Las
Vegas, we rarely recommend this tier for primary kitchen installations — the motor has insufficient power to
handle the mineral resistance that builds up inside the grinding chamber, and it jams on food scraps that a
larger motor handles without hesitation. If you are on a strict budget, a 1/3 HP unit is a short-term
solution.
Best for: Single-occupancy homes with minimal food prep and cooking. Vacation homes
or rental properties where a minimum-cost unit is the priority.
Typical installed cost range: $175 to $250.
1/2 HP — Standard for Most Las Vegas Homes
The 1/2 HP disposal is the
most common residential unit and the starting point we recommend for most Las Vegas households. It handles
normal food waste from a family of two to four people — vegetable trimmings, fruit scraps, soft food debris —
without difficulty. It is available in a wide range of brands and price points. InSinkErator Badger 5 and
comparable units at this tier are reliable, widely supported, and appropriate for most standard Las Vegas kitchens.
Best for: Households of two to four people with normal cooking and food prep volumes.
Typical installed cost range: $200 to $300.
3/4 HP — Recommended for Active Las Vegas Kitchens
A 3/4 HP disposal
handles harder food waste — citrus rinds, small fruit pits, fibrous vegetables — more reliably than a 1/2 HP
unit and recovers from Las Vegas mineral buildup better over time. We recommend this tier for households of
three or more people who cook regularly and want a disposal that does not require constant resetting. The
InSinkErator Badger 9 and Evolution Compact fall in this tier and represent the best value balance for active
Las Vegas households.
Best for: Households of three to five people with regular cooking, households that
frequently process citrus rinds or tougher food scraps, and any household that has had repeated jams with a
1/2 HP unit.
Typical installed cost range: $250 to $375.
1 HP — Premium for High-Demand Las Vegas Kitchens
A 1 HP disposal is the
premium residential tier. It handles virtually any food waste, jams rarely, runs noticeably quieter due to
better motor insulation, and has the longest expected service life of any residential unit. The InSinkErator
Evolution Excel and comparable 1 HP models are the best long-term investment for a Las Vegas household that
cooks frequently, entertains regularly, or has experienced repeated disposal failures with smaller units. The
additional upfront cost versus a 3/4 HP unit is typically recovered in fewer replacement cycles over the next
10 to 15 years.
Best for: Households of four or more people with heavy cooking use, entertaining
kitchens, households that have burned through multiple smaller disposals, and anyone who wants the quietest
and most durable option available.
Typical installed cost range: $350 to $475.

What Affects the Cost of Garbage Disposal Installation in Las Vegas?
We provide exact pricing before any work begins. Here is what determines where your installation falls in the range:
Unit Size and Brand
A 1 HP premium unit costs more than a 1/2 HP entry-level unit. Brand also matters — InSinkErator and Moen are the two most widely supported brands in Las Vegas with the best parts availability and longest warranties. We stock the most common models and can usually install same-day or next-day without ordering parts.
Supply or Install Yours
We install customer-supplied disposals at the same labor rate with no markup. If you want us to supply the unit, we include the cost transparently in the quote. One advantage of having us supply is that we confirm the mounting configuration is compatible with your existing sink flange and drain setup before purchasing — avoiding a mismatch that requires a return trip.
Sink Flange Condition
The sink flange is the metal collar that mounts in the drain opening of the sink basin. When we replace a disposal, we assess whether the existing flange can be reused or needs replacement. A flange in good condition saves time and cost. A corroded, cracked, or mineral-encrusted flange needs replacement as part of the sink installation — budget $30 to $60 for parts and 20 to 30 additional minutes of labor.
Dishwasher Drain Connection
If a dishwasher drains through the disposal inlet, we reconnect that line as part of the dishwasher installation at no additional charge. If a dishwasher is being added for the first time and needs to drain through the new disposal, we configure the inlet connection during installation.
Electrical Outlet Availability
Most disposals plug into a switched 120V outlet under the sink. If an outlet already exists at the disposal location, the electrical connection is a simple plug-in. If the kitchen was never wired for a disposal — common in first-time installations — a licensed electrician needs to add the outlet before we can complete the installation. We can coordinate timing with an electrician and confirm what the electrical scope requires before scheduling.
First-Time Installation
A first-time disposal installation where no unit previously existed requires mounting a sink flange where a standard drain basket existed before, running a new drain discharge connection to the existing p-trap, and ensuring the electrical outlet is present. The plumbing scope adds 30 to 60 minutes to a standard like-for-like swap. Electrical is a separate scope if new wiring is required. Ask about our financing options for larger kitchen upgrades.

"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."
