The Invigoration 2.0 Series is Kohler’s updated steam generator lineup built specifically for residential spa bathrooms. It’s not commercial-grade — and it’s not trying to be. Instead, Kohler focuses on creating a steam experience that feels luxurious, calming, consistent, and easy to control.

You get:

• Fast steam startup

• Stable temperature control

• Smooth, even steam output

• Very low noise levels

• A stainless-steel tank + heating elements

• Minimal maintenance thanks to AutoClean

This is a polished home spa generator, not a heavy-duty industrial unit.

Key Features of the Invigoration Series 2.0

1. Fast-Response Technology

Kohler built this unit to generate steam in roughly one minute, depending on the room size. This means you aren’t standing around waiting for the temperature to build up — you simply start your session, step inside, and the environment warms quickly.

2. Stainless-Steel Tank & Heating Elements

The entire tank and heating system are made from stainless steel, which gives:

• Cleaner steam

• Longer tank life

• Better resistance to mineral buildup

• Lower maintenance over time

This is a major upgrade compared to aluminum or mixed-metal tanks used in older units.

3. Impressively Quiet Operation

Kohler engineered this generator to run very quietly, which is rare for residential steam systems. You barely hear the tank or elements working — the overall experience feels calmer and more spa-like.

4. AutoClean System

Like Mr. Steam’s AutoFlush or Delta Steamist’s AutoDrain, Kohler includes a built-in automatic cleaning cycle.

It:

• Flushes minerals

• Rinses the tank

• Helps prevent scale buildup

• Keeps the unit running efficiently

Minimal maintenance. Maximum longevity.

5. Simple Digital Controls

The Kohler control interface is intentionally straightforward:

• Set temperature

• Set session length

• Press start

• Enjoy

There’s no learning curve — it’s designed for ease of use and intuitive operation.

Sizing Options for the Invigoration 2.0 Series

Full Wattage Range

The Invigoration Series comes in multiple kW options ranging from 5 kW up to 30 kW.

For residential bathrooms, the most common sizes are:

• 5 kW

• 7 kW

• 9 kW

• 11 kW

• 13 kW

This range covers everything from a compact steam shower to a larger in-home wellness suite.

Material Considerations

Your steam room surfaces matter for sizing.

• Marble, granite, natural stone → absorb more heat → often require bumping up one size

• Porcelain tile, ceramic tile → low absorption → stick to the chart recommendations

This is critical to avoid:

• Slow warm-up

• Weak steam

• Temperature swings

Installation Flexibility

One of the advantages of the Invigoration Series is how flexible it is to place.

Kohler allows installation:

• In a closet

• Under a bench

• In a mechanical room

• In an adjacent space

As long as it’s within 20 feet of the steam head.

This gives homeowners and contractors plenty of layout freedom.

Who Is the Invigoration Series Best For?

This generator is ideal for homeowners who want:

• Reliable, quiet steam

• Smooth and consistent temperature

• Fast warm-up

• Low maintenance

• A premium bathroom upgrade

If you’re building a luxury home spa or renovating an older steam shower, this is one of the best residential options available.
