For the longest time, running water and drains have been the most significant advancements in bathing technology. Having the ability to turn a tap to fill your tub and pull a plug to empty it changed human hygiene and sanitation forever. 

It seemed as though we hit a plateau when it came to bathtub innovation, but Kohler’s PerfectFill™ technology is looking to take bath time to an entirely new level. Here’s a look at how their new innovation works and how it could make bath time feel royal.

As an adult, it’s rare to have someone else draw a bath for you unless you happen to be part of a royal family. Kohler’s PerfectFill™ smart bathing technology is looking to change that, though. It gets your tub ready for you, making bath time an incredibly relaxing experience. Here’s what you should know about this innovative tech:

What is it?

Kohler’s PerfectFill™ is a drain kit system that automatically fills your bathtub to the ideal depth at your preferred temperature. It takes all the guesswork out of filling a bathtub, as it allows you to forget about messing with the faucet to get a good temperature and it prevents you from overfilling the tub.

It also drains your tub automatically and you don’t even have to be in the house for it to do so. The result is complete control over your bathtub, no matter where you are. 

Its exciting features

PerfectFill™  operates digitally via the Kohler Konnect app or via voice through a system like Alexa. In order to use the futuristic technology, you’ll need a Kohler bathtub and spout. The starting price for the products is about $2,700. 

On the app, you can set up to ten different profiles of ideal water depths and temperatures for each person in your family. This feature ensures kids don’t end up taking a bath in a tub with water that’s too deep or too hot/cold. 

Quite simply, this technology fills and drains your tub to your specifics, and the entire process is taken care of without you having to lift a finger.

The benefits

Most of the benefits of this innovative tech come down to convenience. 

For example, you can use it to fill the bathtub for your child while you’re washing dishes after dinner or doing something else.  Or, start a bath for yourself on your way home from work that will be waiting for you when you walk in the door. 

By activating the faucet when you’re about ten minutes from home, you can ensure your bath is waiting at the ideal fill and temperature. Walking into a waiting bath can make you feel like you’re going to the spa. 

PerfectFill™ also ensures the tub doesn’t overfill because it only activates the faucet until the pre-recorded water depth is reached and then it shuts off automatically. You can even empty the bathtub remotely if you forget to do so after getting out.

What else you should know

The PerfectFill™ drain system kit with tub requires professional installation to ensure everything is connected correctly. You’ll need to mount the control board in a spot where it can communicate with the tub, as well. As a result, getting the system up and running could take some time.

In addition, the product only comes with the control board and drain. The Kohler brand faucet and compatible bathtub need to be purchased separately. 

It’s not inexpensive, so, depending on how much an easy, luxurious bath is to you will make your choice. 

Are you looking forward to a bath fit for a king or queen? 

Bath time can now be more like a day at the spa with PerfectFill™. It makes bathing super convenient, luxe, and personalized like never before.

    This sounds divine! Having a perfect bathtub ready for me as I come in the door after a long day would be phenomenal! What a great idea.

    Absolutely. I’m also assuming that other tub manufacturers such as American Standard will eventually have the same technology which would be great for those of us who prefer baths

    Yes sounds absolutely amazing and as someone who uses a bathtub more than a shower, this would be perfect for me. I would willingly pay more for a bathtub with this technology. 👏👏❤️❤️
