I've installed many bidet seats for clients and the universal reaction is "why did I wait so long?" The Kohler C3 155 seat is a full featured bidet seat that is a great value for the price. It installs easily with clear instructions on how to hook up to your existing water supply. You will need a power outlet close to the toilet.

I've installed many bidet seats for clients and the universal reaction is "why did I wait so long?" The Kohler C3 155 seat is a full featured bidet seat that is a great value for the price. It installs easily with clear instructions on how to hook up to your existing water supply. You will need a power outlet close to the toilet. While a bidet seat can be a little intimidating at first you quickly learn to use all the features and how to customize it to your needs. The seat does not function unless you are actually sitting on it so that's the best way to learn. This seat has both front and rear sprays that can be adjusted to your needs. All adjustments are made on a keypad on the right side of the seat and you will quickly learn to adjust by feel with a little practice. Many seats offer a remote but personally I don't see the necessity. You can adjust up to 6 levels of heat on the seat surface and the water temperature, and the blow dryer feature is strong and effective. I thought the deodorizer feature was probably a marketing ploy but it actually works noticeably well. There is also a built in blue light for finding the toilet in the dark which gives it a high tech glow and feel. Once you get past being intimidated by a smart seat you really will enjoy the features and wonder how you ever relied on paper before. These are also great for homes on septic systems because not flushing paper is a big load off your system.  Read Less

Per Kohler's installation manual this bidet requires a 120 volt 15 amp dedicated line with a 15 amp GFCI outlet placed within 32 ins. of the bidet seat. I don't have that. I also don't have an attic and I don't have a basement. Installing this line will require a few hours in a 3 ft. high, dirt floor, crawl space. In the spring I'll do a proper installation but for now this is getting powered up with a 12 ga. 20 amp extension cord plugged into a 15 amp GFCI outlet in the next room. The installa... Read More

Per Kohler's installation manual this bidet requires a 120 volt 15 amp dedicated line with a 15 amp GFCI outlet placed within 32 ins. of the bidet seat. I don't have that. I also don't have an attic and I don't have a basement. Installing this line will require a few hours in a 3 ft. high, dirt floor, crawl space. In the spring I'll do a proper installation but for now this is getting powered up with a 12 ga. 20 amp extension cord plugged into a 15 amp GFCI outlet in the next room. The installation of the seat is very simple, the only tools you'll need are a flat head screwdriver and an adjustable wrench or a pair of pliers . Remove the old seat, clean and disinfect the bowl, screw down the new mounting bracket and snap on the seat. The mounting bracket has a large range of adjustability to get the seat positioned just right. The water connection is done with the supplied chromed metal "T" fitting placed between the supply line and the toilet tank. The water feed from the bidet screws onto this fitting. Plug in the power cord and you're done. They also included a supply line, from the tank to the "T" fitting, in the event yours is iffy. I replaced a non-electric bidet seat and was able to reuse the old "T" fitting. The seat has a built-in safety switch which disables all function until it senses weight on the right side of the seat. The LED control panel offers a ton of features. Front cleaning (3 pressure settings), rear cleaning (3 pressure settings), automatic wand extension for manual cleaning, dryer (3 speed settings), heated seat (3 temperature settings), water temperature (3 temperature settings), oscillate / pulsate spray, manual UV sanitize button and deodorizer button. There's also a very cool night light which can be switched off if you don't want it. For cleaning purposes the seat is easily removed from its mounting bracket with a push of a button. If required, the self-cleaning stainless steel retractable spray wand can be cleaned manually with a soft bristled brush and hot water. There's also a 45 minute UV disinfecting cycle which activates automatically once every 24 hours. My well water has a high sediment content, I have filters throughout the house, Thankfully Kohler included a removable filter screen to trap the contaminates before they reach the water reservoir. The seat's a pleasure to use. No more icy cold water, although, that was an eye opener first thing on a winter morning. I lived in Europe where bidets are a common fixture and I can assure you that once you own one you'll appreciate this appliance. Kohler includes a 3 year limited warranty from the date of installation for normal residential use.  Read Less

Installation Is relatively simple. Parts are included for mounting on toilets that have either the tradition seat mounting holes or the newer threaded insert type. The process required removing the existing seat, and attaching the bidet using its own bracket. The bracket is designed to allow the bidet to be slid on and hold it in place. There is a mechanism that allow it to be slid off for cleaning as needed. My unit will sometime not click into the bracket on one side and need to be pushed in... Read More

Installation Is relatively simple. Parts are included for mounting on toilets that have either the tradition seat mounting holes or the newer threaded insert type. The process required removing the existing seat, and attaching the bidet using its own bracket. The bracket is designed to allow the bidet to be slid on and hold it in place. There is a mechanism that allow it to be slid off for cleaning as needed. My unit will sometime not click into the bracket on one side and need to be pushed in repeatedly before it clicks in and is secure. The water connection is also straightforward. A T-Piece is supplied that allows the connecting tube to be attached to the toilet supply. So one has to shut off the water to the toilet, unscrew the supply hose and add the new T-piece and water line. The seat end of the water pipe has a metal fitting on the end which has to be screwed onto a nylon threaded connector on the underside of the seat. It was rather hard to get it onto the fitting and I was worried that the force I had to use to get the thread started would break something. I managed to get it on and thread OK, but it made me double check that it was the right size fitting initially. The biggest hurdle to installation is of course having a power socket close enough for the unit to be plugged in. I added a new duplex outlet on the wall at the height of the toilet tank. The location was close to a power line running past in the basement below which made the job relatively easy. If you are building or renovating, add GFCI power outlets near the toilets. For existing bathrooms you may have to have an electrician install an outlet for you. Once that is in place it is just a matter of plugging in the unit in. I installed the seat on an American Standard one piece toilet. Being very tall, I much prefer the long seat standard over the older round seats. This bidet unfortunately makes the usable length of the seat substantially smaller. The seat has rather a strange slope dowards from the back to the front and one ends up sitting much further forward, which is my case is too far forward. Usage The bidet has a good set of features. It has the front and back wash options, a dryer blower, a deodorizer, a cleaning mode and it even has a night light feature that fills the toilet with a wonderful blue light when the room is dark. Automatic cleaning is performed every 24 hours. Certain functions have settings to control the characteristics of the seat. For example you can control the temperature of the seat, and the water. You can control how hard the water sprays and if the sprayer oscillates. The front to back position of the wand is also adjustable. The settings and controls are all made through a panel on the right hand side of the seat. I find the control panel a little far to the rear and I have to twist around to look back at it. The status of the settings are all indicated with LEDs but they use a peculiar coding system using 3 lights and various flashing modes to indicate the current setting. The documentation states that the status lights are displayed on the remote control, but there is no separate remote and I assume they are referring to the control panel itself or some other model that comes with a remote display. The instructions do not describe what the flashing and non flashing lights indicate. I think that a flashing LED indicate “plus half” so one light and one flashing means 1.5, 2 steady lights = 2, 2 steady and the third flashing = 2.5 and three constant = 3, etc. I have taken off one star for the shortening effect of the seat. We have another bidet seat that does not reduce the length as badly. I took off another star for the insecurity of the seat clipping onto the bracket. With improvement in those two areas it would be much better, and if the length is not too critical for you, just ensure it is properly clipped in. Three year limited warranty  Read Less

The design for this bidet needs to have some usability testing and redesign in order to work for a broader range of customers. The product description needs improvement in describing the limitations of the seat and the Homeowner's Guide needs a rewrite so the instructions don't refer to the settings on the remote when there is no remote supplied with the product.

The design for this bidet needs to have some usability testing and redesign in order to work for a broader range of customers. The product description needs improvement in describing the limitations of the seat and the Homeowner's Guide needs a rewrite so the instructions don't refer to the settings on the remote when there is no remote supplied with the product. This product is highly overpriced and over touted for its capabilities. I do not recommended buying this product. Don't waste your money--especially since its limitations aren't described in the product description and you can't find out about the limitations until you install it and try to use it. You cannot return it once it has been installed. I researched this product and thought I'd found one with a remote. The video on the Amazon website showed the product had a remote. It seems however, that when I selected the Biscuit color, the model type was changed from the one with the remote to the one with the side panreI, which I didn't notice when I hit the order button. I didn't notice the model switch until it got installed but was relieved that the Homeowner's Guide said the settings are shown in the remote. See the photo of the Homeowner's Guide pages that refer to the remote. However, this is wrong--there is no remote. Interestingly, the review form I am filling out for this product with the side panel asks for a rating for the Remote Control feature. (See the photo of the review form feature rating for the remote.) I gave it a 1 star but it should have no star as there is no remote. The bidet with the side panel is probably good for a parent who is standing in front of the toilet and operating the side panel for a child or it is good for a very narrow-width butt adult. The problem is that the side panel can't be seen while sitting on the toilet seat for a butt that is wider than 16 to 18 inches. The side panel is also up behind the butt and is not only not visible but it is difficult to reach the buttons if you have a frozen shoulder and can't contort your arm into position. There are two rows of control buttons. You may be able to reach the outer row by groping around with the thumb and guessing which one in the row you are on by using the Homeowner's Guide illustration as a guide but because some buttons have 5 or more different levels of settings, you don't know which one you are starting with or moving to as (according to the manual) they are only shown on the remote, which doesn't exist. The design has two wands -- one for the Front and one for the Rear. There is supposedly a button that can adjust the reach of the wand forward and backward. I tried all 5 positions on each wand and the length of the stream for the supposed Front wand never gets past the front edge of the parineum so it is not possible to clean the vulva or the front area. I called Kohler Customer Support and they said you can maybe achieve it by contorting your body backward or forward on the seat. It depends on the level of flesh on the stomach and legs that may prevent you from leaning forward enough to achieve the desired angle for the distance. The blow dryer is barely a breath and doesn't accomplish much at all in drying the surface area. You still need to wipe with dry tissues to dry off. Read Less
