You want to try and do almost anything and everything you can to make your home feel cosy, right? Well, there are the obvious ones, like decorating it, and then there are things that you need to prevent, like mould, in order to keep it cosy. Now, bathrooms should be a place of relaxation. A nice, hot shower, a bit of quiet time, maybe even a chance to pretend life is not as chaotic as it actually is. But then, out of nowhere, mould shows up like an uninvited guest who refuses to leave.
It’s awful, right? One day, everything looks fine, and the next, there are dark spots creeping around the shower, up the ceiling, and along the window frame like they are planning a takeover. Well, the bathroom (and technically the kitchen too), is the prime spot to form mould, and scrubbing it away isn’t always the best option. But how can you full-on prevent it from being in your bathroom?
Ventilation is the Ultimate Mould Repellent
Alright, for starters, mould hates fresh air. If a bathroom stays steamy long after a shower, that means moisture is hanging around way too long, soaking into walls, ceilings, and grout. If you have any cracks in your bathroom walls, this is literally the reason why. Plus, that is exactly how those creepy black spots start forming in the first place. You absolutely need an extractor fan or maybe even a dehumidifier.
Pick the Right Bathroom Materials, or Prepare for War
Some materials are basically begging for mould. No, really! things like untreated wood, unsealed caulk, and fabric-based window coverings hold onto moisture for hours, giving mould the perfect hiding spot. This is exactly why choosing the right window treatment matters. Some fabrics trap dampness, turning bathroom blinds into a breeding ground for mould (like wood or bamboo shades, and suede curtains are guilty too).
But Roman blinds, on the other hand, are a much better option because they resist moisture and dry quickly, meaning there is nowhere for mould to settle in and take over. But yes, even your window treatments matter. The same goes for decor and furniture pieces in your bathroom too, like unfinished wood, or basically anything that has bamboo in it, they will mould.
Water Shouldn’t Stick Around After the Shower Does
As gross as it all sounds, basically, a damp bathroom is like an all-you-can-eat buffet for mould, and it will take full advantage. For example, water pooling in corners, collecting in the shower, or hiding in the folds of a shower curtain is an open invitation for it to grow. Plus, a lot of people deal with caulk having mould form underneath (it’s normal but needs to be cleaned, caulk removed, and redone).
So, you’re honestly better off just looking into cleaning weekly or even daily to prevent mould. For example, bath mats and towels should never sit in a damp pile, and any shower curtains need to be spread out so they can actually dry. But the cracks between tiles form mould as well.
