Before you actually start decluttering, you will need a few items to help you. Grab a cardboard box (or two), a couple of large trash bags, a large basket and a timer.
I recommend decluttering multiple bathrooms at once to really get an idea of how much excess is in each room.
Organizing Tip for Bathroom
When reorganizing your makeup, start first with the items you use most/daily. Place those up front so they’re easier to access. Then deal with the rest of your makeup.
Keep your medicine cabinet organized into categories. In my pharmacy basket I have adult medication and children medication separate.
