Kohler Numi K-3901

Summary

The Kohler Numi K-3901 provides one of the most integrated toilet experiences available on the market. Regarding design, it comes in a visually-pleasing, unique square-shaped, tankless design that takes up minimal space, and adds to the chic of a modern bathroom. This Numi is as much of a piece of functional art as it is a top-of-the-line Japanese style toilet.

 

Concerning comfort, the unit is equipped with self-cleaning functions that can be programmed to remember the preferences of the whole family (up to 6 users)! The elongated bowl and patented comfort height make sitting comfortable for most adult users. In addition, the unit has an automated lid that opens and closes according to motion sensors. The heated seat and foot warmer will make a visit to the bathroom in winter something you’ll look forward to, while the power-saving mode automatically adjusts temperature settings to help conserve energy.

 

Perhaps the most exciting aspects of the Numi are its additional features. The unit is equipped with eight different colors of ambient lighting that light-up in the dark. It can also play FM radio or a playlist of your choice that the owner can load to an SD card. Alternatively, a phone can be connected via Bluetooth or an AUX cable to enjoy music from your device while finishing your business. The Kohler K-3901 Numi is more than a smart toilet; it is a conversation piece!

The Good

  • Self-cleaning functions are easy to use and adequate for thorough washing and drying
  • Ambient light feature allows users to use the toilet easily in the dark without the need to switch on overhead lights
  • Water-saving feature uses a 0.6- or 1.28-gallon flush, using much less water than traditional models
  • Emergency flush system can store up to 100 flushes in the event of a power outage
  • The unit is made at comfort height, which is suitable for most adults

The Bad

  • The square seat may be uncomfortable for some users, who prefer the traditional round seat
  • Lid automatically closes after 60 seconds, which makes it challenging for men to do their business standing up
  • Automated lid sensors may not be powerful enough for some users, who have trouble getting the unit to sense their presence and open the lid.
  • Hefty price tag of over $6,000
  • Installation requires the mounting of electric and water hammer arrestors, which may need some renovation work to be done to accommodate them

Bottom line

The Kohler K-3901 Numi is definitely one of the more luxurious hi-tech toilets on the market, with many accessory features such as a foot warmer, ambient lighting in assorted colors, and the ability to connect to devices and play pre-programmed music. The unit is also eco-friendly and the flush system will come in handy during an emergency. On the other hand, the price tag and complicated installation may deter some prospective buyers. In addition, there seems to be some problems with the automated lid, and some users were reported to disable the function to solve the problem.
