As someone who tests luxury home products for a living, I’ve developed a critical eye for items that promise premium experiences but don’t deliver. After all, an impressive price tag should translate to impressive performance. So, when Coway released their Bidetmega 500S, I was intrigued. Could a bidet attachment—even one with a $699 retail price—really elevate the most mundane part of my daily routine?

After a month of testing, I can confidently say this is the gold standard of bidet attachments I’ve encountered, and I’ve tested more than my fair share over the years.

Installation: Surprisingly Simple

First impressions matter, and the Bidetmega 500S scored points immediately with its straightforward installation process. Despite being a premium attachment with numerous features, the setup was surprisingly accessible, even for someone with basic DIY skills. The included instructions were clear, and I had it fully functional in under 30 minutes—a significant advantage for renters who need solutions that can be easily removed later without damaging the property.

Coway offers both elongated and round options to ensure proper fit with your existing toilet, an often overlooked but crucial detail that prevents awkward gaps or alignment issues.

The Luxury Experience

The true test of any luxury product is whether it transforms an ordinary experience into something special, and this is where the Bidetmega 500S truly delivers. The remote control operation allows for a completely touchless experience from start to finish—the lid opens automatically as you approach, and with a press of a button on the sleek remote, it closes itself when you’re done.

The heated seat (with adjustable temperature settings) is a game-changer during colder months, while the water temperature control ensures comfort regardless of the season. I found myself actually looking forward to using the bathroom, which says everything about how this product elevates the experience.

Thoughtful Features That Justify the Price

What separates the Bidetmega 500S from more basic models is the attention to detail in its features:

• The integrated deodorizer immediately addresses odors without harsh chemicals or sprays—a subtle but meaningful upgrade for shared bathrooms.
• The night light provides just enough illumination for midnight trips without the jarring brightness of overhead lights.
• The ability to save two user profiles means my preferred water pressure and temperature settings remain untouched, even when my partner uses different configurations.
• The triple hygiene care system provides thoroughly clean results with a front-to-back cleaning approach that leaves you feeling fresh.

Sustainability Bonus

Beyond the luxury experience, there’s a practical benefit: I’ve noticed a significant reduction in toilet paper usage. The thorough cleaning means minimal wiping is needed, which translates to both cost savings and environmental benefits over time. The eco mode further reduces energy consumption when the bidet isn’t in active use.

The Bottom Line

At $699 (currently on sale for $497), the Coway Bidetmega 500S undoubtedly represents a significant investment in your bathroom. After thorough testing, The combination of thoughtful features, quality construction, and the genuine elevation of a daily routine makes this a luxury purchase I can get behind.

For those seeking the best bidet attachment on the market and willing to invest in a truly premium experience, this bidet sets a standard that more basic models simply can’t match.
