Notes

  • Where the number comes from. The national price for a 50-gallon gas water heater replacement is $1,850 installed — water heater replacement pricing published for 2026, unit plus installation. Labor is about 45% of that. Plumbers, Pipefitters, and Steamfitters near Renton, WA average $96,250 a year against a U.S. mean of $72,170 — a factor of 1.334 — so the labor half is scaled by that and the material half is not.

  • Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
  • What is in the price: the heater, removal and disposal of the old one, new flex connectors, a drain pan, an expansion tank where code requires it, and labor.
  • What is not: a gas line upsize, new venting, an electrical circuit for an electric unit, and bringing an old install up to current code. These are the lines that turn a $2,128 quote into a $2,660 invoice, so ask about each one before signing.
  • Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

a 50-gallon gas water heater replacement in Renton, WA

$2,128 is the typical number, and three bids on the same scope normally land between $1,495 and $3,105.

That is $278 more than the same job priced at the national average.

Why the city changes the number

About 45% of this job is labor — $957 of the $2,128 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

Plumbers, Pipefitters, and Steamfitters near Renton average $96,250 a year, against a U.S. mean of $72,170. That is a factor of 1.334, so the labor half is scaled by it and the material half is not.

What the quote should include

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $2,128 and something a quarter higher.

Use it as a bid check, not a quote

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.

If a bid lands outside $1,495 – $3,105, that is not automatically wrong — but it is the question worth asking out loud.
