I’m a mature adult in his mid-40s who thinks that the U.S. and UK got off on the wrong foot when we decided to go all-in on toilet paper over bidets, and yet I still an slightly embarrassed to have my byline on an article about how much I love the high tech toilet seat I’ve been testing out for the past six months.

And yet the Coway Bidetmega 500S has been such a game changer for me, I’ve essentially become Zach Galifianakis from that SNL sketch where he can’t stop talking about bidets. I’d recommend it to anyone who is bidet-curious—especially when you can get one for $270 off during Amazon’s early Prime Day sale.

Because everything is fancier in the future, the bidets of 2025 are loaded with cool tech straight out of…well, honestly, the Bidetmega 500S has a lot of the same features I encountered 15 years ago when I visited the bathrooms of Tokyo, but we all know Japan is living in 2050, and it appears the U.S. has finally caught up.

Not quite smart, but packed with features

I’m not sure if the world is ready for an AI-powered bidet (there are some areas where I’d like to remain firmly in control of my destiny), but the Bidetmega 500S is about as smart and feature-packed as these things get. Just look at all the options on the remote control:

You control everything using the remote, customizing your preferences for width and angle of spray, water pressure and temperature, and more. There’s a heated seat option, a built-in deodorizer, a nightlight, an auto-open/close lid, and more. If that seems like a lot of decisions to make every time you go to the bathroom, you can also save your preferences and switch between different user profiles at the touch of a button. (User 1 comes pre-programmed to be “kid-friendly” according to Coway.)

Without going too into the details, I find the Bidetmega 500S to have more features than I ever imagined I needed from my toilet seat, and they all, er, work as advertised. I particularly appreciate the option to heat up the seat and have warm water on demand (a big advantage over more basic, tankless bidet attachments I’ve tried in the past). This is all to say, I’m now spoiled for every other bathroom.

Easy installation

As a homeowner, I spent at least a few moments every day imagining the horror of a huge plumbing bill and the related water damage, so I approached installing the Bidetmega with no small amount of apprehension. But I needn’t have worried—it’s a simple matter of removing your old toilet seat, attaching the new one with a few screws, and briefly turning off the water to the fixture so you can attach the water feeder hose to the bidet. It was easy to tighten everything by hand and avoid leaks.

The only thing you have to concern yourself with is choosing the right shape (round or elongated) and measuring in advance to make sure it will fit your toilet—though be aware that you’ll also need a grounded outlet near the toilet to plug it in, too.

A less-fancy option

Even on sale, the Bidetmega 500S is $429, which is on par with many competing models—feature-packed bidets ain’t cheap—but you can save $60 by opting for the Bidetmega 400S, which has most of the same features, minus the auto-close lid and built-in deodorizer. Usually $499, the 400S is marked down to $369 for Prime Day.

Whichever model you choose, your tush will thank you.
