No hot water is never convenient. We install tank, tankless, and hybrid water heaters across the Las Vegas Valley — same-day service available, fully permitted, and built to handle our hard desert water.
Water heater installation in Las Vegas costs between $1,599 and $4,900 for a standard tank replacement (gas or electric), and between $5,800 and $8,000 for a tank-to-tankless conversion.
Clark County requires a permit for every installation, which typically adds $200–$300. A licensed plumber should handle the entire job — not just for legal reasons, but because Las Vegas's notoriously hard water (roughly 280–290 PPM) means an improperly installed or undersized unit will fail years early.
The price depends on several factors:

Call (702) 908 0953💡 Las Vegas Homeowner Tip: If your water heater was installed when you bought the home and you haven't done annual maintenance, assume it's on borrowed time regardless of age. Our hard water accumulates scale inside the tank at a rate that shortens service life significantly without regular flushing.
We arrive, inspect your existing unit, check the gas line or electrical connection, venting, and available space. We confirm whether an expansion tank is required (it is, on virtually all Las Vegas homes with a city pressure-reducing valve) and discuss your household's hot water demand.
We present your options — size, brand, fuel type, and efficiency tier — with an itemized quote for each. No single total-only quotes. You'll see the unit cost, labor, permit fee, expansion tank if required, and any code upgrades called for under the 2018 Uniform Plumbing Code as adopted by the City of Las Vegas and Clark County.
We pull the required permit before starting work. Installation includes removing and properly disposing of the old unit, installing the new water heater with code-required seismic strapping (two straps, per City of Las Vegas requirements), expansion tank, shutoff valves, sediment trap on gas units, drainage pan where required, and a T&P relief valve discharge line to code.
We request the required final inspection from the City of Las Vegas Building Division. After inspection sign-off, we test the unit, verify temperature, check for leaks, and walk you through the maintenance schedule — including how often to flush the tank given Las Vegas's hard water.
This is the question most homeowners ask before scheduling, and the honest answer is: it depends on your household, your home's infrastructure, and your budget. Here's a plain-language breakdown.
Standard Tank Water Heater: The most common choice for Las Vegas homes. A 40- or 50-gallon gas or electric unit heats and stores water so it's ready on demand. Installation is faster, simpler, and less expensive than tankless. The trade-off is standby heat loss — you're paying to keep 40–50 gallons warm around the clock — and a shorter lifespan in our hard water environment.
Best for: Households of 1–4 people, budget-conscious replacements, homes without sufficient gas line capacity for tankless.
Installed cost range: $1,200–$2,100 (40–50 gallon gas or electric)
Tankless (On-Demand) Water Heater: Heats water only when you turn on a faucet — no storage, no standby heat loss. Lasts 20+ years with proper maintenance. The critical caveat for Las Vegas: our hard water at 280–290 PPM will destroy the heat exchanger in 3–5 years without annual professional descaling. A whole-house water softener removes this risk entirely.
Best for: Larger households, homeowners planning to stay long-term, anyone who has ever run out of hot water.
Installed cost range: $3,000–$5,500 (gas, full conversion including permit and venting)
Hybrid Heat Pump Water Heater: Uses a heat pump to pull warmth from surrounding air and transfer it to the water — significantly more energy-efficient than a standard electric tank. Works well in Las Vegas's warm climate where ambient garage or utility room temperatures are high most of the year. Requires adequate surrounding air space (typically 700–1,000 cubic feet) and an electrical connection.
Best for: Homes without gas service, or homeowners prioritizing the lowest long-term operating cost.
Installed cost range: $1,800–$3,200; may qualify for federal Section 25C tax credit up to $600.
Not sure which type fits your home? We'll tell you during the free assessment — no sales pressure, just an honest recommendation based on your home's setup and your budget.
We don't post flat prices because no two installations are identical. These are the variables that move the number:
A 40-gallon electric tank costs less than a 75-gallon gas unit. A non-condensing tankless costs less than a condensing model. Larger households need more capacity. Gas water heaters cost more upfront than comparable electric models but generally cost less to operate annually. If doing a like-for-like replacement, gas stays the right call for most households.
City of Las Vegas code requires an expansion tank on closed plumbing systems — which includes virtually every home on municipal water with a pressure-reducing valve. If your current installation doesn't have one, we add it. Budget $150–$250 for parts and labor.
If you're switching from a tank to a tankless gas unit, your current gas line may be undersized. Upgrading it adds $400–$1,200 depending on run length and current pipe size.
Old B-vent may need to be replaced with properly sized or reconfigured venting. Tankless units require new PVC concentric venting in most installations.
Water heaters in attics, tight closets, or elevated platform installations take more labor time than a standard garage install.
Permits are required by the City of Las Vegas and Clark County ($200–$300 total). For any tankless installation, we also strongly recommend pairing it with a whole-house water softener or inline scale inhibitor to protect the heat exchanger. We'll quote both options during the assessment.
💡 Tax Credit & Rebate Note: Qualifying ENERGY STAR certified hybrid heat pump units may be eligible for a federal tax credit under Section 25C up to $600. Verify current eligibility with your tax advisor, as this program has been subject to annual updates.

"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."
