Is any one aware of any code requirements that would limit where i can locate a hot water tank. I am planning an addition of a bathroom in a small cabin that is going to get municpal service. No gas so I must go electric and I have no faith in the electric tankless. space is tight but i have just enough room in the bathroom beside the WC for the electric water heater. Is anyone aware of any Canadian (manitoba) code restrictions that would disallow that as a location.

as a secondary question I need a tank that is narrow, like 18" or less any brands that jump to mind , most are 20 to 22 inches. I only need a 30 gallon or so.

thanks for your input and advise
