If you are on a budget, a 40-gallon may be the better option for you. Water Heater Efficiency: When it comes to efficiency, a 50-gallon water heater is going to be more efficient than a 40-gallon water heater. This is because it will have a lower recovery time, which means it will take less time to heat the water.
Even if a 40-gallon heater currently meets your needs, having an additional 10 gallons in a 50-gallon heater can be beneficial. That extra capacity allows flexibility, so if your family grows or your hot water needs increase, you won't have to upgrade your water heater immediately.
1-2 people: A 40-gallon water heater is typically sufficient. 3-4 people: A 40-gallon heater may work, but a 50-gallon model can provide more comfort, especially during peak usage times. 5 or more people: A 50-gallon water heater is usually recommended for adequate supply. Consider your daily hot water needs:
Oversized water heaters consume more energy than properly sized models, so your utility costs are noticeably higher. Plus, bigger models are more expensive upfront, so you've also wasted money on the initial equipment purchase. The same goes for tankless water heaters that are too big – they waste energy and money.
A 40 gallon hot water heater can accommodate around 2 to 3 people in a home. This is a rough estimate that will vary based on the number of appliances in your house and the average duration of your shower.

Oversized units find it challenging to maintain a steady flow of hot water when the demand varies. If it is too big, the water heater may need help adapting to the flow rate changes, leading to uneven temperatures during simultaneous water usage in different areas of your home.
In general, a 40- to 50-gallon tank is sufficient for an average household of 2 to 3 people, increasing by 10 gallons per additional person in the home. In a tankless water heater, the capacity is measured by flow rate, calculated in gallons per minute.
It is very common to find a 50 gallon water heater in a 3 bedroom/3 bathroom home. This is not only because the uniform plumbing code regulates the minimum capacity required in homes based on bedroom and bathroom size, but also because a 50 gallon capacity unit will appropriately serve a to 3 bed/3 bath residence.
So a 50-gallon tank would be adequate for the average family of 2–3 children. Other estimates assign slightly more water for each person, saying you'll need a 30–40-gallon tank for 1–2 people, 40–50 gallons for 3–4 people, and 60–80 gallons for 5 or more people.
Forty-gallon water heaters are perfect for homes with one or two people or those living in smaller spaces. On the other hand, 60-gallon water heaters are suited for larger families (of three or more) or if you have a large tub or hot tub.
While today's water heaters are better designed than older models, they still require regular maintenance in order to prolong their lives. With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
With a low gpm head and full hot you should be able to get 20 min out of 50 gallons. Now you turn down the hot and add a little cold and you should get more time in a less hot shower. If you need more time you could turn up the water heater and use a less hot water to cold ratio. That would get you a few more minutes.
Naturally, tanks that heat more gallons of water typically have a higher price point, so the larger the tank size, the more you can expect to pay. For example, the average 40-gallon water heater installation cost runs between $1,000 and $2,500, while its 80-gallon counterpart runs between $2,650 and $3,910.

Typically, the rule-of-thumb is that you want a 40 gallon tank for 1 to 4 people, a 50 gallon tank for 4 to 6 people, and a 50 gallon high recovery or 75 gallon tank for 6 to 8 people. Energy consumption for 40 and 50 gallon standard water heaters is quite comparable.
