Kohler C3-155 Bidet Review

In this review we’re going to take a look at the Kohler C3-155 bidet seat. Along with the Kohler C3-125, we would consider this bidet to be a mid-level product that sits in the middle among all bidets in terms of function and price. By the end of the review, we hope you will walk away with an idea of whether or not this is the right bidet for you. So let’s get right into it!

Design

We’re going to start this review by taking a look at the design of the Kohler C3-155 in terms of its appearance, dimensions, and built.

In comparison to the Kohler C3-125, which uses a tank water heating system to warm water, this bidet seat uses a hybrid water heating system. What this means is that the bidet uses a combination of the two types of bidet water heating systems: by keeping warm water ready in a tank for use (also known as tank water heating system), and by instantly heating more water once the water in the tank runs out (also known as tankless water heating system). Since a hybrid system doesn’t require a large tank to hold the water, one of the first things you will notice is that the C3-155 is less clunky at the back than the C3-125.

When shopping around for a bidet seat, one of the first things you might consider is if you want a bidet with an attached control panel or a remote control. There are advantages and disadvantages to both. For instance, with an attached control you need to make sure there’s enough space on the side of your toilet to install the seat, because the control is attached to the side of the toilet. With a remote control, your toilet seat is more compact, but you need to replace the batteries inside the remote and bidet seats with remotes are more expensive. The Kohler C3-155 uses an attached control panel to operate. On the panel, there are buttons for Stop, Front wash, Rear wash, Wand position, Dryer, Seat Temperature, Water Temperature, Pulsate, Sanitize and Deodorize.

The Kohler C3-155 will only fit elongated toilets. It’s not designed for round toilets. Elongated toilets have an oval shape and are about 18.5 inches long from the mounting bolts at the back to the front, while round toilets have a circle shape and are about 16.5 inches long from the back.

The dimensions of the Kohler C3-155 are 20-5/8” long, 17-5/8” wide, and 5-1/8” tall at the highest point in the back, which makes it a relatively slim bidet seat.

Features

The Kohler C3-155 has a front and rear wash like most bidets. But unlike most bidets, the wand is made of stainless steel which is more durable instead of plastic, and it has an automatic UV light sanitization feature to keep things extra clean. You can use the pulsating feature with the spray that alternates between high and low water pressures and feels like you’re being given a massage.

The cleansing functions of the Kohler C3-155 are highly customizable. You can adjust the water temperature to 5 levels and the wand position to 5 levels. This bidet also features a heated seat that you can adjust to 5 different warmth levels.

There is also a warm air dryer with this bidet that you can adjust to 5 different temperature levels, so including the heated seat and warm water wash, you have all the basic features that provide a comfortable washing experience.

Another great feature is the deodorizer. The deodorizer minimizes odor which is great if the toilet on which you plan to install this is typically used by more than one person! The bidet seat can also be removed quickly at the click of a button so that you can clean the area around the toilet easily.

The one great surprise with this bidet is that it comes with a nightlight! Usually, you can’t get this feature with mid-priced bidet seats, so this is a cool surprise. With the nightlight, which is an LED light that illuminates the bowl, you can use the toilet during the night without having to switch on a bright bathroom light.

Will you need a hot water supply to use this bidet?  The answer is no.  The toilet seat heats water using a hybrid water heating system.  But you will need to plug the seat into an electric outlet.
