Kohler Numi toilet bidet

Control the Numi's many state-of-the-art features with the easy-to-use touchscreen remote (view larger).
Revolutionary Design
The Numi’s design reflects a furniture aesthetic, creating an original toilet profile. A distinctive, pared-down vision blended with personal technology will impress the most technologically savvy user, while the interface provides an easy-to-use experience for just about any member of the family. The Numi is a celebration of the most technologically inspired experience in personal convenience. Streamlined and modern, its ceramic and glass construction is compact in size yet big on comfort. The graceful auto-open and close seat moves when you approach or leave the toilet—always presenting the exterior of the cover. Ambient lighting through frosted side panels give the space a soft light at night, and an indicator light on the floor provides a visual queue to open and close the seat ring hands-free.

Innovative Technology
The Numi is Kohler’s lowest-flow and quietest toilet with best-in-class performance—its intelligent auto-flush setting assists with water conservation, and dual-flush capabilities alternate between 1.28 and .6 gallons per flush depending on need. It meets the standards of both the EPA WaterSense and CALGreen programs.

In addition to flushing technology, other state-of-the-art features have been incorporated into the Numi’s design. Its sophisticated features enhance your environment, allowing you to transform your bathroom into a relaxing space that’s truly yours. Speakers located at the back of the toilet allow you to play a pre-programmed song that comes with the Numi, listen to FM radio, or play music from your own personal music device. It also comes equipped with the option to install external speakers to play music in your shower for sound cohesion throughout the space.

All of these capabilities can be controlled through the Numi’s smart, streamlined, and simple-to-use touchscreen remote that allows you to fine tune every advanced option—from illumination to temperature to sound—to suit your personal preferences. Featuring intuitive icons, 12 language options, and the ability to set and store user preferences, the remote magnetically connects to a wall-mounted docking station for convenient storage and battery charging.

Comfort and Cleanliness
The Numi’s comfort-height, adjustable heated seat offers paramount relaxation, and warm air from a floor-level vent heats the floor surface to warm your feet for added coziness.

The Numi toilet also offers remarkable personal cleansing thanks to its best-in-class bidet functionality. Its durable, stainless steel bidet wand provides precise positioning and unprecedented control over spray pattern, pressure, and temperature. Adjustable front and rear sprays are accompanied by an integrated dryer in the wand with adjustable air temperature settings to dry more effectively. The single faucet-like wand has a removable spray nozzle and a self-cleaning UV light. A deodorizing filter purifies air from within the bowl by pulling it through a charcoal filter that removes odors.

Installation Requirements and Recommendations
A dedicated 120 VAC, 60 hertz, 15 A minimum dedicated circuit protected with a Class A GFCI (ground fault circuit interrupter) or RCD (residual current device) is required.

Kohler recommends installing the Numi according to the included installation guide. Installation of a water hammer arrestor is recommended; install it along with the docking station power cord before installing the finished wall. The supplied water inlet hose requires a supply stop with a 1/2? OD compression male outlet thread. This Numi model is fastened to the floor by mounting blocks—if local codes require the toilet be bolted to the flange, order kit K-1172974 for required hardware and instructions. It can be installed with the water supply and electrical supply attached to the back wall or through the floor—see the art for the 12-inch rough-in for details. Adjust the through-the-floor installation as required to meet all local codes.

Kohler's Numi Warranty
Kohler Co. warrants the vitreous china component on the Numi toilet to be free of defects in material and workmanship during normal residential use for three years from the date of installation. Kohler Co. will further warrant all mechanical parts in the Numi toilet to be free of defects in material and workmanship during normal residential use for three years from the date of installation. This warranty only applies to the Numi toilet when installed in the United States and Canada.

March 2014 Update

The Numi has been in use for two years now and has been performing very well. All of its features are still functioning and my wife and I are still very happy with our purchase.

There has been one flaw in the system and it has to do with the remote. Just recently, when the remote is taken off of the dock it starts to auto restart and shows no charge. I called Kohler's Support at the number on their website and was easily connected to their Tech Support. After describing the problem they decided to ship a new remote to me.
I believe that it's the rechargeable battery that has gone bad and I'm hoping that a new model will allow for replaceable batteries. Till then, Kohler's support seems to be top notch.

So, two years later, I'd still buy this toilet again and am still very pleased with the look and function that this toilet provides.

Original 2012 Review

As part of a bathroom remodel, my wife and I originally purchased a TOTO with a bidet/washlet seat. The problem with the TOTO washlet is that the power and plumbing come out of the side of the seat and look fairly unattractive. Our bathroom design is also quite modern and the TOTO, while being a nice toilet, did nothing for the design of the toilet room.

This is where the Kohler NUMI comes in. It not only has the functionality of the TOTO washlet...

I researched this product and compared it to the other competing products, but still didn't know if it would be worth the money.
I got a great deal on this product through Amazon, though, and it arrived in perfect condition.
I changed my standard water stop valve to a double (1/2" and 5/8") and used one of the valve sides to install a 5/8 " mini-water hammer arrestor as recommended, works perfectly).
Put in my own GFCI outlet and routed the cables to the remote. The installation is pristine. This product was well thought out and executed to perfection.

The toilet works better than I expected, with great water pressure for the bidet, and very strong fan.
The remote allows you to customize features for individual users like BMW does for their driver's seat.
For example, User 1 may not want a front wash, User 2 may want back wash, dry and flush in that sequence).

The nightlight feature is great and the quality of the build and components is first rate.
Scoff as you will, but you often get what you pay for.

This makes our bathroom look like a museum or modern art gallery.

Let's face it, if you're looking at a toilet like this you want something special and of course you'll be making some kind of statement. I decided to purchase this after my wife had hand surgery. I had looked at the Toto but as good as it seemed, it really is a regular toilet with what looks like an add-on toilet/bidet seat. I'm sure it works fine but it's style was blah. Enter the Kohler Numi. There is no question that it is a very unique looking toilet. Contrary to other reviews, the seat is very confortable and the angular shape doesn't affect comfort at all. What Kohler has done is to fully integrate the electronics and plumbing inside the porcelain base. Nothing looks added on.
The toilet also has great features like the rear walls that light up. You can also control the brightness. The bowl has its own night light, too. As you approach the toilet the lid opens. Then a blue light shines on the right side pointed at the floor. Interrupt the light and the seat raises. Walk away from the toilet and it flushes automatically. This can be made manual as well. There's welcome music or FM radio from the built in speakers. Heated seat and warm air blowing on your feet from below are additional features. Of course there is a bidet feature allowing front and back cleaning with programmable temperature and pressure settings. Up to eight individual user settings can be programmed into the remote control. The remote control looks like an iPod which attaches to its charging cradle by magnets. Very clever. Finally it's also a great flusher. No disappointments here and it is very quiet. Now for the really important stuff. I had a problem with the remote control and called Kohler. They were terrific sending out a replacement without a problem.

Purchased the Numi (at substantial savings) through Amazon after a careful review of the documentation and competitive products for a half bathroom remodel that I wanted to add a wow / cool factor to. I was almost put off by some of the Amazon reviews until I realized many of them were from people who don't actually own it.

It's physical footprint is quite small, and it easily fit into the space left after the old toilet was removed. Our plumber had never seen one before but easily and quickly installed it and had it up and running.

For a smooth install it's essential you review (or have someone else review) the installation diagrams and templates. Being a ground floor installation, fishing the new GCFI receptacle was easy, as was the low voltage wire for the remote control dock. We pre wired everything using the dimensions in the (excellent and comprehensive) documentation available online.

In use it's simple, the features are straightforward. Despite some reviews to the contrary, everyone who has used it has found it very comfortable as well.

Expensive? Yes. However we saved most of the difference in price by doing some of the remodel work ourselves, and I think we got a better end result, and definitely a cooler bathroom. There's no doubt we'll install another in the master bathroom when that comes up for remodeling.

It doesn't quite get 5 stars because it lacks some programming capabilities I think it should have, and doesn't have a way (that I can see) to upgrade it's firmware. It really gets 4.8 or so.
