10 Best Japanese Smart Toilet 2026 in the United States

The TOTO SW3084#01 WASHLET C5 is a top-tier electronic bidet toilet seat that excels in delivering comfort and cleanliness, making it a great addition to any bathroom. One of its standout features is the bidet functionality, which offers adjustable water pressure and temperature settings, ensuring a refreshing clean tailored to individual preferences. The heated seat provides consistent warmth, enhancing user comfort, especially during colder months. Additionally, the self-cleaning nozzles and the PREMIST feature help keep the toilet bowl clean by misting before use, preventing waste from sticking.

Another major plus is the air dryer and deodorizer, which contribute to a tidy bathroom environment by neutralizing odors and allowing for a hands-free drying experience. The remote control with two user memory settings is particularly user-friendly, allowing easy customization for different users.

There are a few considerations to keep in mind. Installation may require some DIY skills, and while it's designed for easy setup, those less handy might need professional help. Additionally, while the WASHLET boasts impressive features, the reliance on electricity means it may not function during power outages. The product comes with a limited one-year warranty, which might not be enough for some buyers looking for long-term security.

The TOTO SW3084#01 WASHLET C5 is ideal for those seeking a luxurious and hygienic bathroom experience, with its blend of innovative features and user-friendly design. It’s particularly beneficial for households looking to enhance comfort and cleanliness, though potential buyers should be aware of the installation requirements and power dependency.

The TOTO WASHLET G450 smart toilet offers a solid blend of comfort, hygiene, and convenience that fits well within the Japanese smart toilet category. It features gentle but effective warm water cleansing with adjustable temperature and pressure, covering the essential bidet functions. The heated seat adds noticeable comfort, especially in colder weather. Its self-cleaning nozzles and PREMIST bowl-wetting system help keep the toilet fresh and reduce cleaning effort, while the powerful Tornado Flush and CEFIONTECT glaze prevent waste buildup effectively. The built-in air deodorizer with filters and warm air dryer further enhance the experience by managing odors and drying without the need for toilet paper.

Automatic lid open/close and flush, along with remote control functionality, offer touch-free convenience and easy customization. The night light adds a thoughtful feature for nighttime use. The toilet’s universal height design is a plus for ease of sitting and standing, meeting ADA standards, making it suitable for a broad range of users. On the downside, while it includes many smart features, some users might find the product weight and size a bit bulky for smaller bathrooms. Also, the integrated features, although comprehensive, might feel basic compared to higher-end models with more advanced customization options.

This model is well-suited for those looking for a reliable, comfortable, and hygienic smart toilet experience that does not enter the ultra-premium price or feature range. Customer reviews averaging 4.3 stars indicate good user satisfaction.

Additionally, it comes with a remote control, allowing for easy customization of settings like water pressure and temperature, which can be tailored to individual preferences. The dual-flush feature is an added bonus, offering water-saving capabilities without compromising on performance. The night light is a thoughtful addition, providing gentle illumination in low-light conditions, which can be particularly useful during nighttime visits.

However, there are a few drawbacks to consider. The advanced features and premium material mean that this toilet comes with a higher price tag, which may not be suitable for all budgets. Furthermore, the sophisticated technology might require some time to get used to for those who are not familiar with smart toilets. Installation might also require professional assistance, adding to the overall cost.
