Kohler K-5401

Summary

The Kohler K-5401 is easily recognizable by its unique design; a one-piece unit with a completely concealed floor mount for the most minimalistic look. The model comes with a wall-mounted pad with 2 flush functions, eliminating the need for a flush lever and giving the unit an ultra-modern look.

 

In terms of comfort, the unit is equipped with adjustable UV powered self-washing functions for the most thorough cleansing. Users can change the water pressure and temperature, position of the washing nozzle, and shift between normal, pulsating, and oscillating functions. There are also air-dry and automatic deodorizing systems, complete with a heated seat.

 

Using the Kohler K-5401 is easy with basically most of its functions automated. The lid opens when it senses movement, and the deodorizing system starts up once the user is seated. The flush is also automatic, and the toilet closes the lid after the user has left. For manual flushing, the wall-mounted pad is touchless and offers a full- or partial-flush. An LCD remote control is provided to adjust all the different functions.

The Good

  • Self-washing functions are easy to use and adequate for thorough washing and drying.
  • The wand used for self-washing is cleaned after each session with UV light and electrolyzed water to keep it clean and germ-free.
  • 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 partial flush using 0.8 gallons of water, much less than traditional models.

The Bad

  • Installation of unit may be difficult and require knocking down of walls to mount it properly.
  • The flush system may not work very well in houses with low water pressure.

Bottom line

From reviews, the good points of the Kohler K-5401 seem to far outweigh the negatives. With useful features such as the self-washing function with adjustable settings, automated lids and flushes, and ambient light, the unit is also sleek and perfect for small, modern homes. However, it can be a little pricey for the average homeowner, and usually requires special installation of the wall-hung unit and wall-mounted pad.
