Electric shower? Doesn't that hurt? I assume you mean electrically heated shower?
Anyway, that's typical. High current stuff has it's own breaker (dual breakers in one package for 240/480v). Lights are usually all on one except maybe if you have two floors. Electrical outlets are typically ganged 10-15 receptacles on one breaker. I wouldn't mind rewiring my house so that every room has a seperate breaker for receptacles...

WOW!!! That many? Its illegal here in Utah to have that many outlets on one breaker. 8 is the max and they frown on that many. 6 is prefered. The punk that built my house ran 15 to one breaker. We were always poping breakers. I had to run new wire and fix them. Not easy with the walls complete.
