Where to Find Hidden Mold in the Bathroom

Unless you've recently experienced bathroom water damage, spotting and eliminating mold in your bathroom may not be as straightforward as you thought. Mold is the common name given for thousands of different fungi. The one thing they all have in common is that they grow and spread in moist and dark conditions.

Left unchecked, bathroom mold grows at an alarming rate. It causes expensive damage to flooring, drywall, tile, and ceilings, creating a need for professional mold remediation and restoration. It also causes health problems for humans and pets alike.

How to Find and Get Rid of Bathroom Mold

Grab a flashlight and put on your inspector hat. You'll want to check darkened areas of the bathroom and assess every structure of the room (ceilings, flooring, baseboards, trim, tubs, showers) exposed to wet or damp conditions.

Also scrutinize hygiene items, plumbing systems, and storage areas that may also play host to bathroom mold.

DIY Bathroom Mold Inspection

  • Inspect Your Toothbrush and Caddy
    The tiny amount of water leftover after rinsing toothbrushes keeps them damp enough to encourage mold spores. And the water often trickles down from the toothbrush to the caddy. Indeed, the worst place to store your toothbrushes is on or near sinks and toilets. Cover your toothbrush head. Clean and dry your toothbrush caddy regularly.
  • Examine Your Soap Dish
    Wet soap left on a container provides all the moisture mold needs to survive. Check the top and bottom of the sink-side soap dish and the tub or shower soap bottles and shelving for mold growth. Clean and dry containers with dish detergent or a hydrogen peroxide solution.
  • Check the Bath Mat
    Bath mats offer a soft place to step that helps keep water off the floor and prevents you from slipping. But your bath mat soaks up a lot of water, an ideal breeding environment for bathroom mold. The best practice is to pick your bath mat off the floor after each use and hang it to dry. Also, wash your bathmat once a week.
  • Interior Bathtub or Shower Mat
    Leaving the mat in place invites mold and mildew and also damages the finish of the tub or shower. Hang it to dry after each use. Don't use the edge of the tub; instead hang it high and away from a moist environment (ex. shower stall or towel rack). Clean interior mats monthly with a vinegar and water solution to kill mold growth.
  • Shower Heads
    You may notice mold around the caulking of the sink, bathtub, or in the shower tile grout. But the shower head is a bathroom mold magnet many people overlook. Clean shower heads by soaking them in a one-cup baking soda and 3-cups vinegar mixture.
  • Behind the Toilet
    Mold likes to grow in the damp crevices of the pipes and plumbing behind your toilet. Flushing also creates moisture. If your bathroom isn’t well ventilated, mold can gain a foothold. When you clean the toilet, wipe down the pipework with dish detergent or a hydrogen peroxide solution and dry thoroughly.
  • Under Sinks
    The plumbing for most sinks is housed in a vanity or enclosed area. Therefore, check both the pipework and the cabinetry for bathroom mold. Repair leaks and condensation issues. During routine cleaning, wipe down the cabinet interior with water and dish detergent or a hydrogen peroxide solution.

Toxic Mold Prevention

The mold in your bathroom can easily spread to other areas of your home. In fact, bathroom mold is linked to childhood asthma, fibromyalgia, allergies, and other chronic illnesses.

Some mold cannot be seen, often because of a cracked drain line beneath a bathtub or water damage from a toilet flange leak. It spreads unrestrained under flooring or behind tile.
