The TOTO Washlet G450 kicks off our list at number 5. This integrated bidet toilet is TOTO’s entry level model. It has a convenient compact design with a minimalist appearance that is sure to impress and intrigue guests. It has the great build quality TOTO is known for but does lack some higher end features like eWater+ and a nightlight when compared to its Neorest counterparts.

That being said, the TOTO Washlet G450 is still loaded in perks like an automatic dual flush system (0.8gpf / 1.0gpf). As the name implies, the G450 will automatically flush when you are done using it. It can sense both standing users and sitting users and will automatically choose the flush size based on how it’s used. Manual flushing is activated via the remote control. The TOTO G450 has a Pre-mist system that lays down a fine mist over the toilet bowl when a user approaches the toilet. This creates a slicker, non-stick surface so waste slides right off when flushed. It also features a backup battery option so it can be manually flushed during power outages.

While its bidet functionality is excellent, the G450 flushing performance has been questioned by some users. Also, it has a short warranty period of only 1 year. These factors combined with its high price point for an entry level model prevented the G450 from placing higher on our list.

Coming in at number 4 is the Discovery DLX, Bio Bidet’s top of the line smart toilet. Aimed at those who want the very best in bidet technology and comfort without breaking the bank, the Discovery DLX is jam packed with high tech features. It has a sleek, fully skirted design that is sure to look great in any modern bathroom, while also being easy to clean. A blue LED night light adds to the DLX’s fresh appearance and will come in handy during those late night bathroom visits.

The DLX also has a handy kick button that can raise the lid, raise the seat and then flush the toilet with consecutive presses. A UV light is used to sanitize the nozzle in between uses, ensuring it stays clean and hygienic. Its spray pressure is solid and the DLX’s warm air drying capability is one of the best we’ve tested.  

The DLX has a motorized seat and lid, allowing you to raise and lower them via buttons on the dual sided remote control. But, unlike other smart toilets in this list, it lacks a proximity sensor so the lid won’t open automatically when you approach. That being said, the DLX still presents an excellent package of features and quality at its price point. Combined with its industry best 5 year warranty from Bio Bidet, it’s no wonder the DLX made our list.

Coming in at number 2 is the UXT Pearl from Alpha Bidet. This beautiful combo is Alpha Bidet's long awaited entry into the world of smart toilets - and it is quickly becoming a fan favorite. The UXT Pearl is perfect for those looking for a gorgeous bidet toilet combo that is packed with high end features, backed by an American company, and won’t cost an arm and a leg.

The UXT Pearl features a one piece design that is ultra low profile while still maintaining a healthy seat height. Adding to its luxe design is a white, in-bowl LED night light and a distinctive halo LED light that borders its side control knob. Along with aesthetics that rival the highest end of smart toilets, the Alpha UXT Pearl is packed with some of the most advanced technology on the market today. These features include an arced stainless steel nozzle that is designed to reduce splash back and contamination, an air plasma generator that sanitizes and freshens the toilet bowl, a host of customizable shortcut functions and presets, and a capacitive touch foot sensor.

The Alpha UXT Pearl ranks highly on our list due to its impressive bidet functionality, customizability, build quality, 3 year warranty and affordable price. However, because it’s still a newer model, long term reliability is still to be determined. That being said, Alpha Bidet has an excellent track record of producing quality bidets.

And lastly, the number one bidet toilet combination on the market is the TOTO Neorest AH and its sister, the Neorest RH. Coming in two variations, the Neorest AH and RH share the same features and functions and only differ in design. Whereas the RH has a more rounded design, the AH model offers sharper lines with a unibody lid. Whichever you prefer, know that you are getting the pinnacle of smart toilet design.  

TOTO’s name exudes quality and the Neorest AH and RH embody that to the fullest degree. For lack of a better description, these are the best smart toilets money can buy. They feature TOTO’s eWater+ system to sanitize the nozzle as well as the toilet bowl. They have LED nightlights, excellent flushing performance, and the full gamut of luxury bidet features. Both cleansing and drying performance are well above average and TOTO uses a variety of ceramic coatings and pre-misting to help keep the bowl clean.

But, beyond its many functions and features, what really sets TOTO’s Neorest series apart from the pack is the superior build quality. TOTO built its name on smart toilet technology and the AH and RH ooze quality inside and out. They are covered by a 3 year warranty and the only downside to them is the high price tag. Are they very expensive and meant for luxury applications? Yes. But, are you getting enough performance and quality to justify? We certainly believe so.
