Swear Off Toilet Paper With This Bidet Toilet Seat That's Easy to Install and Costs Less Than $100

Tushy
Tushy

The recent coronavirus-related toilet paper shortage has put the spotlight on the TP-less alternative that Americans have yet to truly embrace: the bidet.

美女视频黄频大全视频It's not exactly a secret that toilet paper is wasteful—to cost 437 billion gallons of water and 15 million trees to produce our yearly supply of the stuff. But while the numbers are plain to see, bidets still aren't common in the United States.

美女视频黄频大全视频Well, if price was ever the biggest barrier standing in the way of swearing off toilet paper for good, there's now a cost-effective way to make the switch. Right now, you can get the space-saving for less than $100. And you'll be able to install it yourself in just 10 minutes.

What is a Bidet?

美女视频黄频大全视频Before we go any further, let’s just go ahead and get the awkward technical details out of the way. Instead of using toilet paper after going to the bathroom, bidets get you clean by using a stream of concentrated water that comes out of a faucet or nozzle. Traditional bidets look like weird toilets without tanks or lids, and while they’re pretty uncommon in the United States, you’ve definitely seen one if you’ve ever been to Europe or Asia.

美女视频黄频大全视频That said, bidets aren’t just good for your butt. When you reduce toilet paper usage, you also reduce the amount of chemicals and emissions required to produce it, which is good for the environment. At the same time, you’re also saving money. So this is a huge win-win.

美女视频黄频大全视频Unfortunately, traditional bidets are not an option for most Americans because they take up a lot of bathroom space and require extra plumbing. That’s where comes in.

The Tushy Classic Bidet Toilet Seat.

Unlike traditional bidets, the bidet doesn’t take up any extra space in your bathroom. It’s an attachment for your existing toilet that places an adjustable self-cleaning nozzle at the back of the bowl, just underneath the seat. But it doesn’t require any additional plumbing or electricity. All you have to do is remove the seat from your toilet, connect the Tushy to the clean water supply behind the toilet, and replace the seat on top of the Tushy attachment.

美女视频黄频大全视频The Tushy has a control panel that lets you adjust the angle and pressure of the water stream for a perfect custom clean. The nozzle lowers when the Tushy is activated and retracts into its housing when not in use, keeping it clean and sanitary.

Like all bidets, the system takes a little getting used to. But once you get the hang of it, you’ll never want to use toilet paper again. In fact, Tushy is so sure you’ll love their product, they offer customers a 60-day risk-free guarantee. If you don’t love your Tushy, you can send it back for a full refund, minus shipping and handling.

Normally, the Tushy Classic retails for $109, but right now you can get the Tushy Classic for . So if you’ve been thinking about going TP-free, now is definitely the time to do it.
