Simplicity....
I like the looks of all this knob and tube wiring, and 2 prong outlets with a 30 amp fused breaker panel. Those were the days, not too long ago, before the ubiquitous 100, 150, or 200 Amp breaker panel with ample outlets in every room.
There's no way I'd live without protection from electric shock, but I have, when doing a remodel, reinstalled 1960s 2 prong outlets, with their Victorian-esque outlet cover, just for the look of it. Ah, these were down stream from a GFI outlet, of course.
One of the reasons I don't do any appliances with 220 is, it's easy enough to install a GFI outlet in line for ALL electrical appliances in your house. There is no reason not to spend the money and have the first receptacle in every circuit be a GFI. If one doesn't want to disturb their existing wiring, put a new GFI outlet right off the panel just for the protection.
You've got to do something, Stan. It's only a matter of time before your heater shorts with the coil breaking, the live wire springing out and making contact with the shell, while your sitting on the toilet and you bump the heater. You'll be instantly fried.
OR
A cartoon bad person comes into your home, while your showering, and throws the heater in the tub, and Sherlock Holmes himself will be necessary to solve the crime of 'The trials and tribulations of STAN'.
OR
a child, or a child-like adult(like myself), decides to play in or around the toilet and while touching that, also touches the outlet that is unusually located right next to both the toilet and the tub, creating yet another mess for you to clean up.
OR......
