Steam Shower Myths — What’s True and What Isn’t?

If you’re researching a steam shower for your home, you’ve probably heard a few of these claims:
“Steam showers use too much water…”
“They cause mold…”

Myth #1: Steam Showers Use a Lot of Water

Truth: They use less water than a regular shower

A modern steam generator uses about 1 gallon of water during a standard 20-minute session.
For comparison:

• Regular 10-minute shower → 20–30 gallons

• Filling a bathtub → 40–60 gallons

• Steam shower → 1 gallon

If you care about water efficiency, steam is one of the most eco-friendly luxury upgrades.

Myth #2: You Need a Large Bathroom for Steam

Truth: Even tiny bathrooms can fit a steam shower

A compact 3×3 or 3×4 ft space is enough for most residential systems.
Size is not the limitation — proper waterproofing and enclosure are.

Small condos, basement bathrooms, and remodels often integrate steam with minimal changes.

Myth #3: Steam Showers Are Expensive to Operate

Truth: A steam session costs less than a cup of coffee

Steam generators are incredibly energy-efficient.
Average session cost: $0.20–$0.50 depending on location and generator size.

High-end systems from brands like Mr. Steam or Kohler use smart sensors to maintain temperature without wasting power.

Myth #4: Steam Causes Mold

Truth: Mold comes from poor construction — not steam

Modern steam showers are built using vapor-sealed, waterproof systems such as:

• Kerdi membrane

• Wedi panels

• Vapor-rated waterproofing

• Sealed corners

• Slight ceiling slopes to prevent dripping

When installed correctly, zero moisture escapes behind the walls.

Myth #5: Steam Showers Are High-Maintenance

Truth: Automatic flushing makes them extremely low-maintenance

Steam generators today include:

• AutoFlush / AutoClean systems

• Mineral-flush cycles

• Stainless steel tanks

• Optional water filters

These features keep the system clean without you lifting a finger.

For regular use, the only maintenance is wiping the tile — something most people already do.

Myth #6: Steam Showers Are Unsafe or Too Hot

Truth: They have advanced safety protections

Modern generators use:

• Digital thermostat controls

• Overheat protection

• Automatic session timers

• UL safety certification

• Temperature limiters

The environment is controlled, gentle, and spa-like — not extreme like a sauna.
