What the Plumber Is Actually Charging You For
Most quotes combine all of this into one labor number. Here is the breakdown of what a standard tank swap includes:
| Line Item | Typical Cost | Notes |
|---|---|---|
| Disconnect old unit | $50-$100 | Shut off water supply, gas/electric, drain connections |
| Drain and remove old unit | $100-$300 | 40-80 gallon tank weighs 100-150 lbs when full |
| Haul away old unit | $50-$200 | Some plumbers include this; others charge separately |
| Install new unit | $200-$500 | Connect water lines, gas/electric, T&P valve, expansion tank |
| Test and inspect | $50-$100 | Check for leaks, verify temperature, adjust settings |
| Permit pulling | $25-$300 | Passed through from municipality; required most places |
| Standard fittings/supplies | $30-$80 | Flexible connectors, Teflon tape, pipe dope |
Home Depot vs Lowes vs Independent Plumber
| Provider | Base Labor | Unit Price | Typical Total | Pros | Cons |
|---|---|---|---|---|---|
| Home Depot | $550-$850 | Retail (no discount) | $1,200-$2,500 | Same-day in some markets; 1-yr labor warranty | Unit markup; subcontracted plumbers; add-ons can inflate price |
| Lowes | $540-$820 | Retail (no discount) | $1,150-$2,400 | Similar to HD; sometimes faster scheduling | Same trade-offs as HD; variable subcontractor quality |
| Independent Plumber | $200-$1,000 | Trade price (cheaper) | $900-$2,200 | Lower total cost; you build a relationship; flexible scheduling | Must vet the plumber; variable availability; you source unit if preferred |
Bottom line: get at least 3 quotes. Independent plumbers typically beat big box stores by $200-$500 on total installed cost, especially if you source the unit yourself.

Frequently Asked Questions
How much does a plumber charge to replace a water heater?
Plumbers charge $200-$1,000 for labor on a standard tank water heater swap and $800-$3,000 for tankless installation. Hourly rates range from $45-$200 depending on your region. Labor represents 30-50% of the total installed cost. High-cost states like California, New York, and Massachusetts have the highest rates.
How much does Home Depot charge to install a water heater?
Home Depot charges $550-$850 for standard water heater installation labor (not including the unit). Their base rate covers basic installation but may not include haul-away, permits, or non-standard connections. The unit is purchased at retail price. Total installed cost through Home Depot is typically $1,200-$2,500 for a 50-gallon tank.
Do you need a permit to replace a water heater?
Most jurisdictions require a permit to replace a water heater, especially for gas units or fuel type changes. Electric like-for-like replacements may not require a permit in some areas. Permit costs range from $25-$300. The inspector checks that the unit is properly secured, the T&P valve is correctly installed, and gas/electrical connections meet code.
Can I replace my own water heater to save money?
DIY is legally permitted in some jurisdictions but prohibited in others without a license. Doing it yourself saves $200-$1,000 in labor but voids most manufacturer warranties, may void your homeowner's insurance for related damage, and requires a permit that a plumber would normally pull for you. For gas units, DIY is significantly more risky and not recommended for most homeowners.
