Anywhere from 15 minutes to 45 minute depending on the temperature of the water coming in. Municipal supplies here range from somewhat above freezing in winter (same for on-board tank in winter) to well over 75 F towards the end of summer after it has been 100+ every day for two months. After a couple days like that, water in the on board tank is warm enough to shower "cold."
Not only does cold temperature make a difference in how long to heat it, makes a big difference in how fast the hot water is used. When the cold water is icy, it gets mixed with a lot more hot water for a shower.
