Home Depot posted a trick that literally everyone needs to try. In your toilet brush holder, pour in some all purpose cleaner. This will help keep the brush clean. And let me tell you, the last thing you want sitting in your bathroom is a dirty toilet brush!!
Fill your bathroom with an everlasting, fresh aroma! Simply place a few drops of essential oil onto the cardboard tube of your toilet paper roll and your bathroom will smell amazing until the roll is complete and you begin again! - I like this idea for keeping the possibly smelliest room in home smelling good.
Good old Martha taught us that rather than buying those ridiculously expensive anti-slip mats for a rug, just turn it over and run a few lines of acrylic-latex caulk every 6 inches or so. Let dry and flip over and your rug wont be going anywhere!
