Replacing a standard tank water heater costs $1,200 to $3,500 installed in 2026, with most homeowners paying around $1,800. Electric units sit at the low end; gas and larger 50–75 gallon tanks run higher once venting, permits, and old-unit disposal are included.

What Affects the Cost
Fuel type
Gas units cost more to install than electric due to venting and gas-line work, but often cost less to run.
Tank size
Moving from 40 to 75 gallons raises both the unit price and the labor to fit and connect it.
Code upgrades
Expansion tanks, new shutoff valves, drip pans, and seismic strapping may be required and add $150–$600.
Location & access
Attic or crawlspace installs, or long runs from the gas/water supply, increase labor hours.
Cost by Region

DIY or Hire a Pro?
Water heater replacement is generally not a DIY job: gas connections, venting, and permits carry safety and code risk. Electric swaps are more approachable for experienced DIYers, but many jurisdictions require a licensed plumber for the permit to pass inspection.
Signs You Need This Now
- •The unit is 8–12+ years old (check the serial-number date).
- •Rusty or discolored hot water, or a metallic taste.
- •Rumbling or popping noises from sediment buildup.
- •Water pooling around the base — a tank leak means replace, not repair.
- •Running out of hot water faster than it used to.
How to Save Money
Questions to Ask Before You Hire
- Is the quote itemized into unit, labor, permit, and disposal?
- Does it include code upgrades (expansion tank, pan, straps) my area requires?
- What's the warranty on the unit and on your labor?
- Are you licensed and will you pull the permit?
- What size and first-hour rating do you recommend for my household?
Frequently Asked Questions
How much does it cost to replace a 50-gallon water heater?
A 50-gallon tank water heater typically costs $1,400–$3,000 installed. Electric models are on the lower end; gas models cost more because of venting and gas-line connections.
Is it cheaper to repair or replace a water heater?
If your heater is under 8–10 years old and the repair is minor (thermostat, element, or valve at $150–$500), repair is usually worth it. Past 10 years, or for tank leaks, replacement is the smarter spend since failure is imminent.
How long does a water heater replacement take?
A straightforward like-for-like swap takes 2–4 hours. Converting fuel types, relocating the unit, or adding code-required upgrades can extend it to a full day.
Should I switch to a tankless water heater?
Tankless units cost more upfront ($2,500–$5,500 installed) but last longer and cut standby energy loss. If you're already replacing and plan to stay in the home 8+ years, it's often worth comparing.
