Homeowner was quoted $3,000 to install a $769 water heater, and plumbers called it 'insane'

"I asked him if that could really be right, and he stood by it."

One homeowner decided to replace a 24-year-old water heater before it failed completely, only to be shocked by a $3,000 installation estimate for a new unit priced at $769.

The resident turned to Reddit’s r/HomeImprovement community to find out whether that kind of quote was typical for a water heater replacement. The response was almost immediate skepticism.

What people said

In the thread, the original poster explained, “My old water heater has 24 years [of] use on it. I decided I’d replace it before it failed.” The poster then said a referred installer came back with a price that seemed far too high: “I get a number over $3000. I questioned the guy if that could be right, he stuck with it.”

Other homeowners agreed the estimate was excessive and shared examples of much lower costs.

One commenter said replacing a 40-gallon unit cost $1,400 total, including labor, materials, and a new shutoff valve.

Another said a “licensed master plumber with good reviews” picked up the heater, installed it, and removed the old one for $1,200.

Even a commenter in a high-cost area said they paid $2,000 all-in for a 40-gallon replacement and added, “OP's $3,000 is outrageous even for me.”

Another user suggested that if the customer supplies the heater, a reputable plumber would more likely charge about $800 to $1,200 for labor and basic installation materials.

While costs can vary from home to home, the general view was that this quote was unusually steep. Several readers also warned against using big-box stores for contractor referrals, saying the middleman setup can add extra markup to what should be a fairly simple replacement.

What are the options?

The most common advice in the discussion was simple: get three quotes. That could mean the difference between paying more than $3,000 for installation and finding a price closer to $800 to $1,200.

Some commenters also brought up do-it-yourself installation, though with important warnings. A few said electric water heaters are often easier and less expensive to install yourself, while gas or propane models were described as more dangerous for anyone without experience.

One user, who said they paid $550 for a Lowe's water heater and $300 for installation, summed up the reaction by saying, “Call around. $3,000 even with parts included is insane.”
