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 | Not published (quoted) | Published: Rheem Performance $499-$759 | Quoted after consultation | Free haul-away; permits handled; labour warranty up to 3 years; same-day Mon-Fri before noon within 30 miles of a store | Installed by authorised local providers, so the installer varies by market; code upgrades charged extra |
| Lowes | Not published (quoted) | Tank and labour sold together | Quoted after free consultation | Disposal and permit handling included; price-match guarantee on comparable installs; same-day or next-day in select markets | 1-year labour warranty for most categories; attic or crawlspace fee; will not install a tank you bought earlier |
| 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. Neither Home Depot nor Lowe's publishes an installation price, so the only way to compare them with a local plumber is with written, itemised quotes for the same tank. Home Depot and Lowe's terms from their own installation pages, read October 2026. If you do buy the unit, check the water heater replacement cost by size guide first so you know the fair unit price for your capacity.

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 does not publish an installation labour price; it quotes after a consultation. Its installation page says the price has four parts: the product, basic installation, permit charges, and bringing the system up to code. Delivery and haul-away of the old unit are free, Home Depot says it obtains the permits, and its installations carry a labour warranty of up to 3 years. The tank prices are published: in October 2026 its installation page listed Rheem Performance tanks from $499 to $759.
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.
