That said, those looking to give their bum the the royal treatment are in for a surprise. Tushy is now offering 30 percent off on all their top-rated bidets now through Dec. 4.

“The analogy I always give is, imagine if you jumped in your shower, didn’t turn the water on and just used dry toilet paper,” Miki Agrawal, founder of Tushy, previously told Well+Good. “Why are we doing that to the dirtiest part of our bodies?”
