Why Steam Happens in the First Place

When you shower with hot water, the heat causes water molecules to evaporate.  This creates water vapour that rises and spreads through the bathroom air.  As soon as that vapour hits a cooler surface like a mirror, window, ceiling, or painted wall, it condenses back into liquid droplets — creating the mist, streaks, and dampness we all know.

The Domino Effect of Steam in Bathrooms

That innocent fog has a bigger impact than you might realise:

1. Condensation = Damp Surfaces
   Constant exposure to moisture means paint starts to peel, plasterboard weakens, and timber can swell or rot.

2. Mould & Mildew Growth
   A damp environment is the perfect breeding ground for mould spores. Once they take hold, they’re difficult to remove and can affect both health and property value.

3. Higher Cleaning & Maintenance Costs
   More scrubbing, repainting, and replacing damaged materials over the years.

4. Poor Indoor Air Quality
   Steam lingers in the air, raising humidity and making the whole home feel damp, especially in winter.

Why Extractor Fans Aren’t Always the Answer

Many people assume extractor fans solve the steam problem, but in reality:

• Fans remove warm air, not just steam – making bathrooms colder and less comfortable.

• They push moist air into roof cavities or outside, which can cause hidden moisture issues elsewhere.

• They don’t stop condensation from forming in the first place.

How Showerdome® Solves the Problem at the Source

Instead of trying to deal with steam after it escapes, Showerdome® prevents it from forming in the first place.  By sealing the top of the shower, hot air and water vapour stay inside, eliminating steam build-up in your bathroom.

• No more foggy mirrors or wet windows.

• Warmer showers without drafts.

• Lower maintenance and cleaning needs.

• A healthier, drier bathroom for years to come.

✅ Takeaway: Steam is simply science at work – hot air meeting cool surfaces.  But left unchecked, it leads to mould, dampness, and costly damage.  A simple solution like Showerdome® stops the problem before it starts, giving you a drier, warmer, healthier bathroom.
