These are the words that fill Realtors' hearts with terror: carpet in the bathroom. They know that wall-to-wall carpet in the bathroom is instant death for a house's selling potential. Full bathrooms are considered to be high-moisture environments because they have bathing facilities. Once moisture gets in and under carpeting—and especially the padding—mold, and mildew can develop.
Still, if something was a trend once, it might rear its head again in the next 20-year trend cycle. Professional carpet installers recommend following this advice if you really want to install carpet in a bathroom:
Choose Manmade Materials
Look for 100% nylon, polyester, PTT (Triexta Polyester), or polypropylene (olefin).
Avoid carpeting that is made from organic materials such as wool.
Keep the Pile Low
Lower pile (thickness) means fewer problems because less moisture can be absorbed. Lower pile carpeting also dries faster.
Choose an Appropriate Style
Look for loop or needle-punch styles. While not exactly the lap of luxury—resembling a hotel conference room, more than anything—these styles ensure that the pile remains low and flat.
Needle-punch is essentially outdoor carpeting. But if your notion of outdoor carpeting is stuck in the past, you may want to update these notions by looking at contemporary outdoor berbers. They are thick enough that they feel like real carpeting, yet thin enough that they dry out quickly.
Install a Water-Impermeable Subfloor
Consider Installing Carpeting Squares
What happens when your wall-to-wall carpeting gets moldy beyond repair? You find yourself renting out a roll off dumpster because all of the carpeting needs to be removed and replaced.
Carpet square tiles represent the perfect storm of bathroom carpeting but in a good way. They are:
- Modular, so that they can be removed and replaced individually as needed.
- Low pile, so they dry fast.
- Easy to self-install. Peel off the backing to reveal the adhesive.
- 100% nylon.
Keep the Carpet Clean
When it comes to mold, water is not the only culprit.
Lab studies have shown that clean carpeting is less prone to developing mold than dirty carpeting, even when both carpets are subjected to the same amount of moisture.
In short: dirty carpeting plus water equals mold.
Pick Adhesive That Will Not Dissolve
Make sure you use indoor/outdoor carpet adhesive. A good, solvent-free, commercial-grade adhesive may advertise that it is resistant to water.
Minimize Moisture in the First Place
Avoid excessive water by ensuring that your bathtub or shower stall is leak-free.
Just as you would mop up puddles of water from impervious surfaces, do the same with your bathroom carpet.
A wet-vac is your best friend for getting up moisture from carpet quickly.
Use a Mat
Lay down a bathmat on top of the carpet. While it may seem odd to put carpet over carpet, this first layer will catch most of the water from bathers exiting the shower or bathtub.
