This is what I saw, too.

eta: there are two doors by the bar. Configure the floorplan to put the bedroom in the corner so it has a legal egress. (And just in case you have windows, but didn't show them, the tiny little basement windows aren't enough.) If you want to keep the bedroom in the same place, you can install a window well with a legal window.

Yes, thank you for mentioning! It's not in the render but there is an egress window in that room behind/above where the bed will be.

We were fortunate that was put in originally. Flooding from a previous owner (bank repossessed/no power) destroyed most of the basement so we are getting everything fixed back up.

Right so far, but consider a thought experiment. After the first 20 gal of hot water has been drawn, the “bottom half” will be full of cold that the water heater is heating. But we know that there will be mixing, thus the hot water coming out after 10 minutes will be colder than the first gallon. Notably colder, because the tank is pulling in 50-60 degree water (typical in North America). And this will continue, so the “40 gal” capacity will be felt in the shower as exhausted well before 40 gallons of use.

….and it’s illegal because it’s dangerous - no escape from a fire that can be out of control before a person wakes up.

Edit: look up building codes for windows. Typical basement windows don’t count. There are rules about size and height off the floor. You’d have to dig a window well and cut the concrete to put in a legal window.

This is a great suggestion, but the real issue is that due to dry times and quantity of windows- and doing this on weekends, it’s going to probably take 2 summers on and off to get to the remaining 30 windows on level 2. It needs to be something I “own”.

>It lasts maybe 2 or 3 showers then runs out.

That honestly sounds about right. A lot of shower heads are about 2 GPM, so if you have a 40 gallon heater that's only gonna be 20 minutes to completely empty the tank.

But it's worth doing routine maintenance to see if there's anything that needs fixing: Flush the tank, visually inspect the elements, test them for continuity, pull the anode and while it's out check the dip-tube, and test that the lower thermostat is working. All of those could contribute to colder showers.
