Adding a master bathroom next to guest bath. I know enough to do it myself just need help with vent location. Older house, on septic tank, septic was upgraded so no worries there, but the current bathroom and kitchen share the same vent.
Can the pros help me with the layout?

will you be extending a wall out for the shower. looks like a good place for a vent. Separate one for the vanity.
