Running toilet, water on the floor, a rocking base, or a flush that barely moves waste — Royalty Plumbing diagnoses and repairs every toilet problem in the Las Vegas Valley. We tell you exactly what is wrong and what it costs to fix before any work begins.
Toilet repair in Las Vegas typically costs between $75 and $275 depending on which component has failed. A flapper or fill valve replacement — the most common toilet repair we perform — runs $75 to $175 depending on the valve type. A wax ring replacement for a leaking or rocking toilet base runs $150 to $250. A tank-to-bowl gasket and bolt replacement runs $125 to $200. A supply line and shutoff valve replacement runs $100 to $175. A full tank rebuild replacing all internal components runs $175 to $275. Las Vegas hard water at 280 to 300 PPM accelerates wear on every rubber and plastic component inside a toilet tank — flappers, fill valves, and float assemblies deteriorate faster here than in soft-water markets. We give you the exact cost before starting any work.
The price depends on several factors:

Call (702) 908-0953Las Vegas hard water at 280 to 300 PPM is harder on toilet internal components than in most U.S. cities. Mineral scale deposits on flapper seats and fill valve components, rubber seals stiffen and crack faster from mineral contact, and the slab construction throughout Las Vegas creates specific flange and base stability issues. These are the signs that a repair call is overdue:
We open the tank, inspect the fill valve, flapper, float assembly, and tank-to-bowl connection. We check the base for any movement or moisture indicating a wax ring issue. We assess the supply line and shutoff valve condition while we are already there. In Las Vegas, what presents as a single symptom — a running toilet — often has a secondary contributing factor. Hard water scale on the flapper seat can cause a new flapper to fail within weeks if the seat is not cleaned during the repair. We check for this.
We tell you what failed, what the repair costs, and whether the toilet is worth repairing. A toilet under 10 years old with a failed flapper is worth repairing without question. A toilet over 15 years old that has lost significant flush performance from mineral scale accumulation in the trapway and rim jets, is running on its second fill valve replacement, and uses more water per flush than a current WaterSense model may be better served by replacement. We give you both options and the cost of each.
We replace the specific failed component — flapper, fill valve, wax ring, tank gasket, supply line — using quality parts appropriate for Las Vegas's hard water mineral load. For flapper replacements, we clean the flush valve seat before installing the new flapper — mineral scale on the seat will destroy a new flapper's sealing surface within weeks if it is not addressed. For wax ring replacements, we check the flange condition before setting a new seal and repair the flange if needed.
We restore water supply, run multiple flush cycles, verify the tank fills to the correct level and stops, confirm no running, check the base for any movement or moisture, and clean up the workspace completely before leaving. You flush it yourself before we pack up.
Flapper Replacement
The flapper is the rubber seal at the bottom of the toilet tank that opens during a flush and seals the flush valve seat to stop water flow when the tank is full. When the flapper deteriorates — which happens faster in Las Vegas due to mineral contact on the rubber — it no longer creates a complete seal against the flush valve seat. Water slowly leaks from the tank into the bowl, triggering phantom refills. Running toilets waste 200 gallons or more per day. Flapper replacement is the most affordable and most common toilet repair we perform. When we replace a flapper, we also clean the flush valve seat — mineral scale on the seat destroys new flappers prematurely if it is not removed.
Typical cost: $75 to $150.
Fill Valve Replacement
The fill valve controls water flow into the tank after a flush. In Las Vegas, mineral scale from hard water progressively narrows the fill valve's internal passages, causing the toilet to fill slowly, noisily, or not at all. Fill valve failure also causes continuous running when the valve cannot close completely. Replacement with a quality fill valve appropriate for Las Vegas's water pressure and mineral content restores quiet, fast tank refill. We replace the supply line at the same time since the water is already off.
Typical cost: $125 to $200.
Wax Ring Replacement
The wax ring creates the watertight seal between the toilet's drain horn and the toilet flange set in the slab. When the wax ring fails — from age, a toilet that has been rocking, or a flange that has shifted in Las Vegas's caliche soil — water escapes around the base with every flush. This is sewage-contaminated water and requires same-day service. Wax ring replacement — which is also standard practice when resetting a toilet during a bathroom remodel — requires removing the toilet, inspecting the flange, setting a new wax ring, and reinstalling the toilet with new flange bolts. We always inspect the flange during a wax ring replacement — a cracked or corroded flange on a Las Vegas slab home prevents a new wax ring from sealing correctly and must be repaired before the toilet is reset.
Typical cost: $150 to $250 for standard wax ring replacement. Additional cost if flange repair is required.
Tank-to-Bowl Gasket and Bolt Replacement
The large rubber gasket and two tank bolt assemblies that connect the toilet tank to the bowl create a watertight connection at the flush valve outlet. When the gasket or bolt washers deteriorate — accelerated by Las Vegas mineral water — water drips from the connection point with every flush, appearing as moisture at the base of the tank where it meets the bowl. Gasket and bolt replacement requires removing the tank, replacing all sealing components, and reinstalling. We do all three components in a single visit regardless of which one is visibly failing.
Typical cost: $125 to $200.
Supply Line and Shutoff Valve Replacement
The braided supply line that runs from the wall shutoff valve to the toilet fill valve, and the angle stop shutoff valve itself, are frequently corroded or mineral-encrusted on Las Vegas toilets regardless of the home's age. We inspect and report their condition on every toilet repair visit. If the shutoff valve cannot be fully closed — which we confirm by testing it before starting any repair — we replace it during the same visit. A shutoff valve that fails during a toilet repair or future service call floods the bathroom with no way to stop the flow until the main shutoff is reached.
Typical cost: $100 to $175 for supply line and shutoff valve replacement at one toilet location.
Rim Jet Descaling
The rim jets are the small angled holes under the toilet bowl rim through which water flows during a flush. In Las Vegas, mineral scale from 280 to 300 PPM hard water progressively blocks these jets — reducing flush force until the toilet requires multiple flushes to clear the bowl completely. Rim jet descaling involves using a citric acid solution to dissolve mineral buildup from the jet openings and restoring full flush flow. On toilets with severe jet blockage, we use a small pick to physically clear each jet opening. This is one of the most underperformed maintenance services in Las Vegas — and one of the most effective.
Typical cost: $75 to $125.
Full Tank Rebuild
When multiple components inside the tank are failing simultaneously — a common situation on toilets over 8 to 10 years old in Las Vegas's hard water environment — a full tank rebuild replaces the fill valve, flapper, float assembly, and tank-to-bowl gasket and bolts in a single service visit. This restores the toilet to like-new internal function, eliminates the component replacement cycle, and is often more cost-effective than addressing each component separately on sequential service calls.
Typical cost: $175 to $275.

We give you exact pricing before starting any repair (ask us about financing for larger repairs). Here is what determines where your job falls in the range:
A flapper replacement is the least expensive toilet repair — a low-cost part and 20 to 30 minutes of labor. A wax ring replacement involves removing and resetting the toilet and is the most labor-intensive single-fixture repair we perform. The specific component determines both parts cost and labor scope.
For any repair that involves removing the toilet — a wax ring replacement or a significant base inspection — we check the flange before resetting. A cracked, corroded, or low-sitting flange on a Las Vegas slab home adds repair scope and cost before the toilet can be correctly reinstalled. We quote flange repair before proceeding. Typical flange repair adds $100 to $250 to the job depending on the repair type required.
In Las Vegas, a toilet that needs a flapper replacement often also has significant mineral scale on the flush valve seat, a fill valve that is operating below rated flow, and a supply line that is corroding at the connections. Addressing only the presenting symptom while leaving secondary hard-water-degraded components in place is a setup for a second service call within 6 to 12 months. We report secondary findings and give you the option to address them in the same visit.
A toilet over 12 to 15 years old with a failed fill valve, mineral-blocked rim jets, reduced flush capacity, and a supply line that has not been changed is often at the end of its cost-effective repair life. We tell you when the cumulative repair cost approaches the cost of a new toilet installed, and give you the replacement cost alongside the repair cost so you can make an informed decision.
We apply a straightforward rule: if the repair cost is more than 50 percent of a new toilet installation, or if the toilet has reached a condition where Las Vegas mineral buildup has permanently compromised its flush performance, we recommend replacement and explain why. We never take repair money for a toilet that is past its useful service life.

"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."
