In-Depth Comparison Between KOHLER K-922 And K-923 Bath Filler
Now that you have drawn some basic ideas about both products and their difference, let’s get into more details and discuss some key comprehensive differences.
- Filler Type

K-922 and K-923 are laminar wall or ceiling mounting bath fillers from luxurious bathroom item manufacturer Kohler.
They are extremely high-quality products with sturdy materials and a chrome finish design, but there are subtle differences between them.
Kohler K-922 has 0.8 inches or 20 mm orifice. On the other hand, Kohler laminar wall or ceiling mount bath filler has a 0.95 mm orifice.
It means K-923 has a larger orifice and can fill more water at a given time.
- Filler Materials
We all know Kohler is a luxurious bathroom accessory manufacturing brand. They never compromise with quality. And material fills a significant portion of a product’s quality.
Both bath fillers are made from solid and durable materials.
Kohler K-922 has a solid-brass construction and offers durability and reliability in the long run. Besides, Kohler’s excellent finishes can resist corrosion, tarnishing, and other impurities.
At the same time, Kohler K-923 bath filler comes with a solid brass construction for reliable and long-lasting performance. Because of the strong material and chrome finish, your bath filler will go on for decades without causing any problems.
- Features
A product is known by the features it holds. And in the case of Kohler K-922 and K-923 bath fillers, you will see many similar features.
For example, both fillers have a pressure compensating flow control and deliver a splatter-free water column.
With an Easy to access cartridge, you can clean and replace both fillers quite easily. In addition, they complement all Purist faucets and accessories.
However, the main difference lies in the size of their orifice. K-922 has a 20 mm orifice, whereas K-923 has a 24 mm orifice. But both of them provide a well-optimized performance while filling water in your bathtub.
K-922 is compatible with K-924 Optional Drip Tray Accessories. And K-923 is compatible with K-23723 Faucet Cleaner.
- Benefits

Since both fillers have many similar features, you will get almost identical benefits. They have easy access and easy replacement cartridges, which you can clean quickly and fast.
You know they will last longer because of their superior construction materials.
Chrome finishes give both Kohler bath filers an elegant look and feel very smooth in hand. But K-923 will fill your tub quicker than K-922.
And because of the corrosion and wear-resistant coating, the K-922 tub filler will last longer than you imagine.
Apart from water filling speed and protective coating, all other benefits are the same for both bath fillers.
- Water Filling Capacity
One of the most significant differences between K-922 and K-923 is their water filling speed. This single aspect can make you go with one particular filler.
A Kohler K-922 bath filler can flow water at 5 to 10 gallons per minute. But the water might start splashing if the flow rate is less than 5 gallons per minute.
On the contrary, the flow rate of Kohler K-923 is 7 to 15 gallons per minute. Here the water will start splashing too if the rate is less than 5 gallons per minute. As we can see, Kohler K-923 will fill your tub faster than K-922.
- Available Colors
Bath fillers’ colors can be an essential factor for many people. You, too, will want to buy a filler matching your bathroom tiles and walls. So, having more options is always a blessing.
You will get many color options from the K-922 filler. There are 7 available colors, to be exact. Polished Chrome, Vibrant Polished Nickel, Vibrant French Gold, Vibrant Polished Brass, Brushed Chrome, Vibrant Brushed Nickel, and Vibrant Brushed Bronze.
In contrast to K-922, Kohler K-923 is available in two colors. You can choose between Polished Chrome and Vibrant Brushed Nickel.
So, it’s clear that Kohler K-922 offers many more colors than its counterpart K-923.
- Installation Method
Installation is easy for both K-922 and K-923 bath fillers. You can install them either on your bathroom wall or ceiling.
So, the fillers are versatile as they can be installed on both your bathroom wall and ceiling.
But you can install the brass-made handle on your wall only. Make sure you install the handle at an easily accessible place.
- Filler Dimension & Weight
Although these two bath fillers have different water filling capacities, their size is similar. The exact dimensions of K-922 and K-923 are 7.25 inches by 7.25 inches by 7.5 inches.
But their weight is different from one another. The weight of K-922 is 3.04 ounces, but K-923 is 5.56 pounds. So, K-923 is heavier than K-922, even though their size is precisely the same.
Which Bath Filer Will Be Best For You?

From my above discussion, it’s clear that there are no significant differences other than their water filling speed, available colors, and weight.
So, the choice is clear. Let me say it loud anyway.
If you want to fill your tub faster and do not have issues with more weights and less available color, you should go for Kohler K-923. It will fill your tub at 7 to 15 gallons per minute.
But you will get only two color options, and the weight is higher than its counterpart.
On the other hand, if you want more color options and less weighted filler and have no problem with a less water filling speed, you must purchase Kohler K-922 filler. You can choose from 7 available colors,s and it also has corrosion and tarnishing resistant finishes.
Final Thoughts
You must have found it intimidating to choose the right one between these two bath fillers since they have many similarities. But after reading my KOHLER K-922 vs. K-923 reviews, I’m sure all your confusion is gone now.
With all these intensive discussions and differences between their features, you will be able to distinguish between the fillers and purchase one that fulfills your expectations.
