New to Prime Day? We’ve got the lowdown on everything you need to know . Sales are accurate at the time of publication, but prices and inventory are always subject to change.

I’m a mature man in my 40s and I think the US and UK got it wrong when they decided to put toilet paper in place of bidets, and yet I feel a little awkward signing off on an article about how much I love the high-tech toilet seat I’ve been testing for the past six months.

Still, the Coway Bidetmega 500S was such a game changer for me that I basically became Zach Galifianakis from that SNL sketch where he can’t stop talking about bidets . I’d recommend it to anyone interested in bidets, especially when you can get one for $270 during Amazon’s early Prime Day sale.

Since everything is going to be even more trendy in the future, the bidets of 2025 will be packed with cool tech straight from… well, to be honest, the Bidetmega 500S has a lot of the same features I encountered 15 years ago when I visited toilets in Tokyo, but we all know Japan is living in 2050, and it looks like the US has finally caught up.

Not exactly smart, but with lots of features

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

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

Without going into too much detail, I found the Bidetmega 500S to have more features than I ever thought I’d need in a toilet seat, and they all, er, work as advertised. I particularly appreciate the ability to heat the seat and get warm water on demand (a big improvement over the simpler, pressureless bidets I’ve tried in the past). All that to say, I’m now spoiled in every other bathroom.

Easy installation

As a homeowner, I spend at least a few minutes each day imagining the horror of a huge plumbing bill and the associated 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 the old toilet seat, attaching the new one with a few screws, and briefly shutting off the water to the fixture so I could attach the water supply hose to the bidet. It was easy to tighten everything by hand and avoid any leaks.

The only thing you need to worry about is choosing the right shape (round or elongated) and measuring it beforehand to make sure it will fit your toilet. However, keep in mind that you will also need a grounded outlet near the toilet to plug it in.

A less fancy option

Even on sale, the Bidetmega 500S is priced at $429 , which is comparable to many competing models—bidets with lots of features aren’t cheap—but you can save $60 by opting for the Bidetmega 400S, which has most of the same features except for the auto-close lid and built-in deodorizer. The 400S is normally priced at $499, but it’s marked down to $369 for Prime Day.

Whatever model you choose, your butt will thank you.
