The PureWash® E590 Elongated bidet toilet seat delivers a thoughtfully packed, user-focused upgrade tailored to most elongated toilets. Featuring a heated seat with five adjustable levels and a hybrid continuous warm-water system, it offers customizable water temperature, oscillating or pulsating wash modes, and precise nozzle positioning to ensure a comfortable cleanse. Hygienic enhancements include a stainless-steel wand with nightly UV self-cleaning and an active carbon deodorizer, enhancing freshness. Supporting everyday ease are Quiet-Close and Quick-Release features, while practical additions like an LED nightlight, seat sensor to prevent accidental sprays, and grip-tight bumpers enhance user experience. Though the rear-mounted side control can be awkward to access and read while seated, and some users find the dryer and high-pressure spray underpowered, the installation requiring a nearby GFCI outlet (with occasional complaints about supplied plastic fittings) reflects minor trade-offs. This bidet seat emphasizes comfort and hygiene, balanced by a few usability and installation considerations.

Design and Aesthetic Appeal

Boasting a sleek, low-profile design, the PureWash® E590 seamlessly complements most elongated toilets with a modern, unobtrusive aesthetic. Its ergonomically contoured seat enhances comfort, and the Quick-Release™ mechanism facilitates thorough cleaning by enabling easy seat removal. The Quiet-Close™ lid prevents abrupt slamming, contributing to a more user-friendly experience.

While the side-mounted control panel offers large, tactile buttons for ease of operation, its placement slightly behind the seat can make it awkward to reach and read, particularly when seated. Complementing these features is a soft blue LED nightlight that gently illuminates the bowl to aid nighttime visits, though its brightness might be intrusive for those sensitive to light. Installation necessitates a dedicated GFCI electrical outlet and water connection, potentially complicating setup for some.

Balancing thoughtful ergonomic design with technological enhancements, the seat delivers a well-rounded user experience, though certain control placement and installation aspects may require an adjustment period or extra effort.

Performance and Features

The PureWash® E590 bidet seat provides a comprehensive suite of features centered on personalized cleansing and hygiene. Users benefit from adjustable water temperature, pressure, and nozzle positioning for both front and rear washes, with options for oscillating or pulsating sprays to enhance comfort. The warm-air dryer offers adjustable temperature settings, albeit with a somewhat gentle airflow typically necessitating additional drying.

Comfort is further assured through the heated seat, featuring five adjustable warmth levels, paired with a hybrid water heater for continuous warm water supply. Hygiene is elevated by the self-cleaning stainless steel wand utilizing UV light for nightly sanitization, coupled with an effective carbon-filter deodorizer that significantly reduces odors. A seat sensor prevents accidental spray activation by ensuring wash functions operate only when the seat is occupied.

However, the side control panel's awkward position far back can make it challenging to view or adjust settings while seated. Some users report the spray pressure is insufficient even at higher settings for a thorough cleanse. Furthermore, the design lacks a remote control and feminine wash mode, potentially limiting convenience and options for certain users.

Owner-installed C3-155 Bidet Toilet Seat

This bidet toilet seat is a great update to our bathroom. The installation of the seat is fast and straight forward and the bidet components work as advertised. The hard part of the installation has nothing to do with the bidet seat, itself. I tried installing a 15-amp outlet next to the toilet by tapping into a receptacle in an adjacent bedroom. This worked but I discovered that the circuit I used also had an exhaust fan and two 320-watt lights that are located in the master bath two rooms away...
This bidet toilet seat is a great update to our bathroom. The installation of the seat is fast and straight forward and the bidet components work as advertised. The hard part of the installation has nothing to do with the bidet seat, itself. I tried installing a 15-amp outlet next to the toilet by tapping into a receptacle in an adjacent bedroom. This worked but I discovered that the circuit I used also had an exhaust fan and two 320-watt lights that are located in the master bath two rooms away. The master bath and the bathroom with the new bidet seat, share three GFI-protected 20-amp outlets. I removed the newly installed cable from the 15-amp circuit and tapped into the GFI load cable (not the GFI line cable), creating a 4th 20-amp GFI protected outlet next to the toilet with the new bidet seat. This 2nd configuration works and the lights in the master bath are no longer blinking. I have a lot of experience with home electrical systems so I felt comfortable adding an outlet next to the toilet in the aforementioned bathroom. I also have experience with water supply connections and had no trouble modifying the water supply connection to the toilet to accommodate the water inlet for the bidet seat. The electrical work took place in the attic over a period of days and the plumbing part took about one hour. The bidet seat installation took about 20 minutes. I think a dedicated 15-amp circuit would have worked fine assuming that no other circuits would be added in the future. If you are adding a new circuit coming from the electrical panel, it would be advisable to add a dedicated 20-amp GFI circuit. With respect to the bidet seat installation, the instructions are slightly misleading where it says to slide the seat towards the attachment bracket. The bracket has a "lip" that the seat must ride over to drop, and then snap, into place. I found that you can slide the seat until there is contact with the bracket and then slightly lift the seat over the lip and use a gentle downward force to snap the seat into place. I also found that while attempting to slide the seat into its bracket, one side would connect but not the other. In this case, the seat was floating above the edge of the toilet bowl on the unconnected side. I thought it best not to try to force the unconnected side into place but to reverse the process and try again. I found that removing the seat for cleaning works exactly as indicated by the instructions.

Easy to assemble, works great. I really don’t like the nightlight, but you can turn that off. Since it’s a heated seat you gotta keep the rim of your bowl COMPLETELY clean because the heat activates the smell of the slightest tiny fleck of pee. Good excuse to practice better hygiene, I guess. The seat is super comfortable, the contour feels great to sit on. It does look a little funny, because it sticks up so far in the back, but that’s not a surprise. It’s pricey, but very well made and works great. So far the wand keeps itself pretty clean too. Coming from a cheap cold water only biden seat, this is a massive upgrade.

Summary

Delivering a notable blend of advanced cleansing technology and thoughtful design, the PureWash® E590 Elongated bidet toilet seat stands out as an excellent choice for those seeking enhanced bathroom hygiene and comfort. With a wide range of adjustable settings—including water temperature, spray pressure, and heated seat levels—it accommodates a variety of personal preferences and comfort needs. The dual front and rear wash modes, coupled with oscillating and pulsating spray options, add versatility, although some may find the highest spray pressure less robust than expected.

Ergonomics take center stage through the seat's design and grip-tight bumpers, which ensure stable and comfortable seating, while the Quick-Release™ feature eases cleaning and maintenance efforts. The Warm-Air drying system, customizable though relatively gentle, may still require supplemental toilet paper. Additionally, automatic deodorization with a carbon filter effectively manages odors, complementing the built-in self-cleaning wand that uses UV light to maintain hygiene without manual input.

Practical features such as the LED nightlight provide convenient illumination during nighttime, though brightness levels have elicited mixed feedback for potentially disturbing sleep. The ergonomically crafted side control panel with large buttons enhances usability, but its position can be awkward to reach or see clearly from a seated position, especially for larger users. Installation requires a dedicated GFCI outlet and water supply connection, which might present challenges for some.

In summary, the PureWash® E590 excels in cleansing performance and design quality, offering a strong balance of functionality, hygiene features, and user comfort. While minor drawbacks exist—such as moderate water pressure and side panel accessibility—the advanced specifications and thoughtful conveniences make it a compelling option for consumers seeking a reliable, hygienic bathroom upgrade. This combination of solid performance, comprehensive features, and ergonomic considerations earns the PureWash® E590 a recommendation as a premium bidet seat prioritizing personalized comfort and cleanliness.
