The next step is to create a new layer for adding the bathroom fixtures.
As with previous steps where new layers were added, the same process must be followed to create a layer for the Bathroom Fixtures.
First, open the sidebar.
Second, lock the Stairs layer since no additional changes will be made.
Fourth, as before, double click on the new layer (Layer 7) to rename it to Bathroom Fixtures.
Lastly, make certain the Bathroom Fixtures layer is selected and then dismiss the Layers Panel by clicking outside of it.
The Layers Panel should appear as shown below once these steps have been completed.
