Worse, when pulling the toilet brush out of its holder, 'nasty' water from the brush may flip up on the towel or toilet paper.
It's just not a sanitary situation. You don't want to dry your hands on a towel that might have water from the toilet on it.
And, you definitely wouldn't want to wipe with toilet paper that could have also been sprayed with toilet water (and not the good kind!)
When you go to 'wipe' with the soggy toilet paper, you also won't really know if the wetness is from the brush, or from just using the towel.
Are you willing to take that chance?! ...Now all it needs is a toothbrush holder function, too. : )
At least it is a nice space saving design, and certainly a good 'conversation piece' for your home.
