About the Company

The Kohler company has a reputation for devising functional and aesthetically-pleasing products. Their shower line features streamlined and intuitive controls for their fast-acting generators.

Shower generators produced by Kohler are in the moderate price range, depending on the kW used. Your budget needs to be a bit bigger if you add the control kit or the optional adapter steam shower kit.

Although Kohler is a reliable brand with a 3-year warranty for generators and a 5-year warranty for controls, it lacks the array of customizations and extra features you can get with high-end brands, like Steamist.

SUMMARY: Kohler is a reputable brand with quality, albeit middle-range products. Although it lacks the extra customizations you can find with more expensive products, Kohler offers functional and good looking models.

1. KOHLER K-5529-NA Invigoration Generator, 9 kW, Aluminum

KOHLER K-5529-NA

The Kohler K-5529-NA Invigoration is my best choice because it works for most bathrooms, it’s quality, and corrosion-proof.

Although I discuss the 9kW model, you can find K-5529-NA steam shower units in more kW, depending on how big your bathroom is.

The K-5529-NA keeps an even temperature because it’s built with insulated stainless steel. The unit is powerful enough to produce 240 cubic feet of steam at a constant pace thanks to Constant Steam Technology. So even if the temperature in your shower room fluctuates, the K-5529-NA won’t care.

Your steam bath is ready in a minute so you can enjoy a quick steam bath even when you didn’t plan for it. You can take as many baths as you like without worrying about corrosion of cleaning.

The Kohler finishes are corrosion-proof, and the Power Clean Technology ensures auto cleaning in safe conditions.

PROS
  • Various models
  • Constant temperature
  • Lots of enveloping steam
  • 1-minute steam bath
  • Corrosion-proof
  • Quick cleaning
  • Easy to install and easy to use

2. KOHLER K-5533-NA Steam Generator, 13kW

Kohler K5533

K-5533-NA is more expensive than K-5529-NA. This model is more powerful considering that it requires 13kW and that it covers a maximum volume of 447 cubic feet, for medium bathrooms.

The K-5533-NA also features Power Clean Technology, which requires you to push just one button for cleaning the generator. This technology is user-friendly as well as safe.

Just like the Invigoration, the K-5533-NA can produce enveloping steam in under a minute courtesy of the Fast-response technology.

This model works with the Kohler DTV steam adapter and system. You will need the K-5548-K1 DTV to work, as well as the K-5557 Invigoration control kit. Unfortunately, you need to purchase them separately.

PROS
  • Powerful
  • Easy to clean
  • Quick and effective steam
  • Easy installation
  • The K-5557 manual is very clear
CONS
  • Requires additional purchases

Summary: The K-5533-NA is a powerful model for medium to large baths. Although it’s an effective, functional model, you will need to purchase additional kits.

3. KOHLER K-1713-NA Fast-Response 15 kW Fast-Response Steam Generator

KOHLER K 1713

The K-1713-NA is best for luxury baths because it doesn’t ruin your décor and because you can fit it in bigger bathrooms. Don’t use this model in tiny baths, or you’ll get an Err5 as your bath heats over the max allowed temperature.

The K-1713-NA Fast-Response Steam Generator has similar features to the models above, such as the Fast-response technology for 1-minute steam showers and the Power Clean Technology for auto cleaning with just one touch.

The main difference is that this generator covers 500 cubic feet max, meaning it’s best for larger baths. Considering that it needs 15kW to work, it’s one of the most powerful steam generators in the Kohler line, but it uses more electricity.

Another advantage is that you can install it 25 feet away max from the control panel. If you don’t want to ruin your bathroom’s décor with a shower generator, stash the K-17-13-NA in a nearby closet!

PROS
  • Fills your bath quickly
  • Easy to clean
  • Powerful
  • For larger baths
  • You can install it 25-feet away
CONS
  • It uses a lot of electricity
  • You have to purchase the K-1647-PC Fast-Response Steam Generator Control Kit separately

KOHLER K-5531-NA, 11 kW

The K-5531-NA, 11 kW is best for sitting in the tub and enjoying the soothing comfort of a steam bath because it works quickly and you can add Shower oils to amplify your relaxation experience.

The K-5531-NA has the same Fast-response technology to create enveloping steams in 60 seconds, plus the Power Clean technology for auto one-touch cleaning.

The K-5531-NA works for medium to large bathrooms considering it can cover 317 cubic feet.

If you want a digital, one-touch operation for all your adjustments, you can add the optional Kohler DTV and showering system.

PROS
  • Comfortable
  • Relaxing
  • Quick
  • Easy to clean
  • For medium to large baths

5. KOHLER K-5525-NA, 5 kW

KOHLER K-5525-NA

The K-5525-NA, 5 kW is best for small bathrooms because it can only cover a volume of max 56 cubic feet. However, this shower generator will offer a healing experience, especially if you suffer from nasal congestion or muscle aches.

The Fast-response technology guarantees you have a steam bath ready in under a minute. The Power Clean Technology ensures you can auto clean the shower generator with one touch. If you need more one-touch operations and controls, purchase the Kohler DTV showering system.

PROS
  • Quick
  • Easy to clean

The K-5547 uses a lot of electricity for its powerful engine. However, it can cover extra-large bathrooms considering its max volume rating is 1000 cubic feet.

This powerful and reliable steam generator is best for people who have joint mobility issues.

That’s because you can lay down in your tub or on a bench in your bathroom to let the enveloping steam ease your joint pain and improve your flexibility.

PROS
  • Fast-response technology for 1-minute steam baths
  • Power-clean technology for auto-cleaning
  • For extra-large baths
  • Works with Kohler DTV

The K-5543-NA is best for large to extra-large bathrooms considering that it requires 22kW and that its max volume rating is 634 cubic feet.

A DIY steam shower installation is not recommended with a Kohler steam generator according to their official website.

The best news is that your local Kohler dealer will make all the arrangements, so you won’t have to bother with things like head installation.

The appointed team of electricians will install your transfer switch and connect your generator to the switch and to the fuel source, like propane or natural gas.

Many people who tried installing a Kohler generator by themselves had serious difficulties, such as not being able to start the generator.

The electricians sent by your Kohler dealer will know how to reset or repair a troublesome generator, how to deal with error codes and troubleshooting problems, and how to read your water inlet screen.

SUMMARY: Although the installation costs about $2,000, Kohler takes care of everything, including contacting the team of expert electricians and handling the permits.
