It’s normal for some condensation to form on bathroom surfaces after a steamy shower or a long soak in the bathtub. However, if moisture lingers on porous surfaces too long, it can lead to structural problems that are costly and time-consuming to fix. Here, we explain why too much humidity is a problem and offer six simple and effective ways to reduce excess moisture and improve bathroom ventilation.

Signs of Excess Moisture

Sure, bathrooms are often damp or steamy. But how wet is too wet? And how do you know if humidity is a problem?

Here are some signs your bathroom is too humid:

  • Peeling paint
  • Flaking wallpaper
  • Mold and mildew
  • Musty odors
  • Rotting wood
  • Deteriorating plaster

Hopefully, you can reduce humidity before problems develop. Yet if you notice mold or mildew, or deterioration in walls and floors, it’s best to contact a professional contractor. They can assess the extent of the damage and ensure the space is structurally sound.

If it’s time for a complete bathroom renovation, your local Re-Bath consultant will oversee every step of the process—from design to installation. Our products are water and mold-resistant for a bathroom that is always beautiful and easy to maintain. Now, let’s look at ways to combat moisture for a healthy bathroom.

1. Install an Exhaust Fan

Every bathroom should have an exhaust or extractor fan that pulls damp air out of the space and away from the home. Fans can be your most powerful tool for regulating humidity levels and keeping your bathroom comfortable. Turn it on when you bathe or shower, and let it run for 20-30 minutes after you’re done.

If you live in a high-humidity climate, you may want to install a humidity-sensing bathroom fan. These fans have a built-in sensor that detects humidity levels and automatically turns on and off as needed. Some fans also have a timer you can set to run after someone uses the bathroom.

All bathroom exhaust fans require routine maintenance to function correctly. Cleans fans at least twice a year to remove dust and debris. Make sure the vent to the outside is clear and unobstructed. Repair or replace fans with wear and tear, and units that run noisier than usual.

2. Wipe Down Surfaces

Every time you take a bath or shower, wipe down damp surfaces with a towel, including those puddles by the drain. This prevents condensation from sitting on walls and floors and helps speed up the evaporation process. The sooner your bathroom dries, the less time mold and mildew have to grow. Drying up also keeps floors from becoming slick and slippery, helping to prevent dangerous falls.

3. Use a Dehumidifier

Dehumidifiers also help to minimize condensation, reduce odors, and prevent mold and mildew. You can install a whole-house unit or opt for portable humidifiers you can plug into a bathroom outlet.

Humidifiers are classified by how many pints of condensation each unit can collect per hour and per day to achieve 30- 50% relative humidity in a room. A unit that collects under 40 pints daily is suitable for a small bathroom. Medium-size bathrooms require a humidifier to collect 40-60 pints of moisture daily.

Measure your space and check product specifications to find a suitable model for your bathroom. Additional features you might look for in a humidifier include HEPA filters to improve air quality and lights that notify you when the water tank is full and needs to be emptied.

4. Choose Materials Wisely

The materials in your bathroom can either retain moisture or resist it. Waterlogged surfaces are more prone to damage, and they’re a breeding ground for mildew and mold. That means you’ll spend more time cleaning to keep your bathroom looking bright and beautiful.

Re-Bath products are designed and manufactured to be water-resistant and low-maintenance. DuraBath™ Acrylic seamless tub and shower surrounds are non-porous and completely waterproof. They come in several color choices and can be customized to mimic the look of granite, travertine, and limestone. Thus, you can have the look of natural material without the upkeep.

DuraBath™ Natural Stone wall systems are also waterproof. Because our Natural Stone panels are engineered with an alloy backing, they are 800% more durable than traditional stone. Available in customizable sheets, Re-Bath DuraBath stone sheets are also sealed for easy cleaning.

Have you ever spent an afternoon cleaning or replacing dirty, damaged grout? If so, you’ll be happy to know that Re-Bath products are silicone-sealed and waterproof to protect against moisture, mildew, and mold. This speeds up installation and makes cleaning a breeze.

Reduce Moisture in Bathroom

5. Add Live Plants

Plants are a great way to make bathroom spaces more inviting—while reducing moisture in the air. The best bathroom plants thrive in humid conditions and absorb moisture from the air while releasing oxygen to improve overall air quality. Think of them as nature’s dehumidifiers!

These indoor plants are beautiful and functional:

  • Aloe Vera
  • Bamboo
  • Begonia
  • Boston fern
  • Cactus
  • Calatheas
  • English Ivy
  • Orchid
  • Pothos
  • Snake Plant

Remember that not all plants are ideal for bathrooms because some release water vapor that increases humidity. When in doubt, choose plants from the list above, or check with your local home & garden center to find the perfect greenery for your space.

6. Open Windows and Doors

If you live in a mild climate and aren’t running the heat or AC, bathroom windows and doors can improve ventilation. Open windows 20 minutes before bathing and showering, and leave them open for a bit after you’re finished. You can also leave the bathroom door open to allow humid air to escape.

If you notice condensation collecting on the interior side of bathroom windows even when you use an exhaust fan or humidifier, it might be time to upgrade to energy-efficient double-paneled windows. Condensation that collects between panes may be a sign the seal needs to be replaced.
