Could be the anode rod failing in your water heater provided it’s a tank water heater. Sometimes easy to replace, sometimes very difficult. They are not expensive
On a well, the magnesium anode rod should have been changed to an aluminum-zinc anode rod. The magnesium rods break down and cause the sulfur smell. Not replacing an anode rod that has deterated can lead to tank failure. If the water had sulfur impurities causing the smell, it would be in the cold water side also.
I call bullshit. It took a four foot cheater bar to break mine loose. Manufacturers don’t use anything on the threads on purpose, so they have to tighten the shit out of those rods to prevent leaking.
Magnesium does great with most public water systems. On well water, there are not as many treatments to the water. The zinc in the anode rods works with well water much better than magnesium rods because zinc stops the bactrim in well water from attacking where magnesium anode attracts the Bactrim then creates hydrogen sulfide gas that makes the rotten egg smell in the hot water.
There are a few possible causes. This website explains them, and offers corrective measures.

Depending on your well water, it could also be iron eating bacteria. they are harmless but do create a sulfur odor. Learn about shock chlorinating the well and water heater to remove this. it's a simple process and some homes need it once a year or so.
Do you use city or well water?
Bacteria reacting with the magnesium-aluminum anode rod causes that. Usually not a problem because most people use their hot water every single day but If your hot water tank has been sitting for a few days, the bacteria population becomes more concentrated and thus more hydrogen sulfide gas is created making the snell much more obvious
To fix this you can either shock your well system (if you are on a well) with Chlorine Bleach, disinfect your hot water tank with hydrogen peroxide or have the magnesium- aluminum rod replaced with a zinc-aluminum rod.
Anode rod definitely affects the water smell lol. 100%. Generally when someone on city water smells flushing the system and replacing the anode rod is the fix.
So was it the flush? The bleach? Or anode replacement? Do 1 at a time and see what happened. Why would you put chemicals in your water heater? Explain how the anode effects the smell of the water.
I have lol. But yes I’ll explain it. As the rod corrodes it attracts minerals that cause the smell, which causes hydrogen sulfide gas. This is a common issue with water heaters that have a sulfur smell.
I need you to realize here this is legitimate, and take the moment to learn here. You are 100% incorrect in your original comment. I’m not trying to be condescending here but I know how Reddit is and likes to argue, but take it away as learning something new today. I’d say there is a 75% chance OP needs a new anode rod, that’s the first place to start on this situation.
This was actually supposed to go to the other comment but it’ll work. Yeah bleach? Weird.
So which solved your issue? You did 3 things and can't verify which worked. If you have water high in suffer to begin with the anode can make it worse. The high sulfur can be filtered out and will make the smell go away. A normal clean water supply won't have a sulfur smell. Tell me what solved your issue. Flush?Bleach? Anode? You don't know do you?
Wrong comment my guy. But I’d say 75% of the time replacing the anode rod is the culprit for sulfur smell. I just say flush the water heater completely for general maintenance when doing work as a good practice. In my area and how hard the water is, everyone should flush theirs once a year.
But as mentioned the anode rod building leading to hydrogen sulfide is generally the culprit.
Over 40 years of work and never had a sulfur issue with a water heater. Plenty of them leaked, just did one last week. Put in plenty of water filter systems with bad smelling and bad tasting water.
You might as well hang the cap up if you don’t know the basics. Not a plumber but I understand some of this shit. Go sweep jobs instead of trying to give bad advice on the internet
Lol. Your not a plumber but you understand some of this shit? You tube videos i bet.
I am 60 years old and will out work you 7 days a week for the next 10 years. Go change out an another anode, you seem to be an expert at that.
Bacteria from well water can grow within the water heater. This bacterium is not harmful to you; however, it is creating a reaction with the magnesium metal on your anode rod. This leads to hydrogen sulfide, which brings the sulfur or rotten egg smell.

Magnesium does the job better I've heard tho.
Put in an electric anode and call it a day. If the water heater is relatively new it should be easy to remove the old one

Just run the hot water on all your faucets for a while. When water sits in your tank for a few days it gets a little funky.
Get a full water test on it. Your well water may have changed. Anode will not effect the water smell.

I just did a flush, and a bleach treatment and replaced my anode rod and my water still smells so 🤷🏼♂️

It could have depend where you are, as if you’re in a hard water area it’ll be more common. In my area, (Midwest) it’s more common.
I live in the midwest and our water is hard. Never heard of it happening around here.
