Medium and tall versions hold the same volume in a different shape.
What sits between the shelf price and a 50 gallon install bill is labour, fittings, venting or wiring, the permit and haul-away of the old tank. No national price list for that work is published (Home Depot's installation page gives no price), so get it as a written quote. For scale, the median US plumber earned $30.67 an hour in May 2025 (BLS); that is pay, not the rate a firm bills, which also covers the van, insurance, overhead and profit.
Right Use Cases
Who a 50 Gallon Tank Suits
A 50 gallon tank is the usual choice for three to four people with two bathrooms. It gives room for two showers in a row, or a shower alongside the dishwasher, without running cold.
Five or more people, or three bathrooms used at once, push toward the 75 gallon water heater installation cost page or a tankless unit (see tank vs tankless). Two people with spread-out showers can drop to the 40 gallon page.
Regulatory Context
The 2029 DOE Rule and the 50 Gallon Electric Tank
The DOE consumer water heater final rule moves electric storage tanks from 20 to 55 gallons (other than small tanks of 35 gallons or less) to heat-pump efficiency for units made from 6 May 2029. DOE's average installed cost rises from $902 to $1,855, and first-year operating cost falls from $340 to $171 (2022 dollars).
On the shelf the gap is already visible: Home Depot listed the Rheem ProTerra 50 gallon heat pump at $1,950 against $569 for the Performance 50 gallon electric on 13 Nov 2026. The 120V plug-in model ($2,119) is designed for homes without a spare 240V circuit at the tank.
Gas tanks from 20 to 55 gallons get a higher minimum efficiency from the same date ($1,578 average installed, against $1,432 today). The rule applies to tanks made from that date; a working tank never has to be replaced. More on the heat pump decision page.
The federal Section 25C tax credit ended for property placed in service after December 31, 2025, so no federal credit applies to a 2026 install. State and utility heat-pump rebates still run in some areas; check your utility before you buy.
