We currently have one shower and looking to install one more. Below is the laundry layout and the plan that I am thinking by looking at some of the inspirations online(attached a picture which I like). This is my 1st ever project (I will outsource this not doing DIY). I don't need a toilet in laundry, have a separate toilet beside the laundry. Please let me know if there are any more ideas for the layout. And Do I need council approval to close the door to wall.
