Secondhand shopping can be smart—except when it puts your safety and home at risk. Interior designers reveal six home décor items you should always buy new, and the surprising reasons each can cost you far more than you save.
Scoring unique home furnishings at a thrift store can feel like a triumph. But while buying secondhand is often touted as sustainable and budget-friendly, some items come with hidden risks that can impact both your health and the quality of your space. Top interior designers are increasingly vocal about a shortlist of décor items they say are never worth buying used, no matter how tempting the price tag.
The Rise of Secondhand Shopping—and Its Pitfalls
The desire to shop sustainably and affordably is at a record high, with the resale market projected to double in the next few years. While thrift shopping offers vintage charm and eco-cred, it’s important to remember that not every pre-loved item is harmless. Many secondhand décor pieces can harbor bacteria, allergens, or hidden damage, making them a false economy.
Reflecting on years of industry experience, designers such as Elizabeth Vergara of Vergara Homes and Kerrie Kelly, FASID, NKBA, creative director of Kerrie Kelly Design Lab, have shared their professional warning list for home décor shoppers. Here’s their definitive guide to what should never make it into your cart—plus actionable advice for a healthier, smarter home.
Lamps With Old Wiring: Vintage Appeal, Modern Risk
Retro lamps can transform any space with character, but if they come with decades-old wiring, the dangers far outweigh the decorative potential. Electrical safety is the chief concern: “Wiring from decades ago isn’t always safe,” notes Elizabeth Vergara. Unless you’re committed to professional rewiring or converting to battery-powered bulbs, pass on the plug-in variety every time. Faulty wiring can cause shocks or even house fires—a risk that drastically exceeds the cost of buying a certified new lamp. Martha Stewart
Throw Pillows: Hidden Hazards You Can’t See
Throw pillows are decorative darlings, adding color and comfort to sofas and beds. Yet beneath the fabric surface lurk risks almost impossible to sanitize out: bacteria, dust mites, and allergens. Even rigorous cleaning may not neutralize what’s deep inside the stuffing. Designers recommend only buying pillow covers secondhand if they can be removed and washed—otherwise, always opt for new inserts to ensure true cleanliness.
Bath Mats: Moisture Magnets for Mold and Bacteria
Bathrooms demand the highest standard of hygiene, making bath mats and shower curtains risky thrift finds. These items trap moisture easily, allowing mildew, bacteria, and mold to thrive out of sight. Thorough cleaning can’t guarantee removal of all contaminants. For peace of mind and health, rely on factory-fresh mats and opt for vintage-inspired looks if you crave character.
Plastic Décor: Low Quality, High Likelihood of Decay
Thrift shops brim with plastic items, from dinnerware and trays to storage and decorative pieces. However, plastic deteriorates over time—warping, discoloring, or even releasing toxins as it ages. Interior designers caution that plastics of unknown vintage can pose both aesthetic and safety problems. Instead, thrift for natural materials like wood, stone, or ceramic, which retain integrity over time.
Area Rugs: A Minefield of Allergen and Odor Issues
Area rugs ground your room’s style, but buying them secondhand is fraught with pitfalls. Moth damage, pet stains, allergens, or “off-gassing” chemicals might not be visible but will quickly make themselves known at home. Rug backing, especially old latex, can also crumble. Unless you have confirmation of the rug’s history and can professionally clean and treat it, the risks often outweigh any vintage value Martha Stewart. Those with allergies or sensitivities should be especially cautious.
Window Treatments: Sun Damage and Sizing Nightmares
Window coverings—from curtains to blinds—may seem like great thrift finds, but they often come with issues like sun rot, odd sizing, and the need for specialized hardware. Inconsistent panel lengths and faded fabric create a patchwork look that frustrates many home improvers. Experts recommend reserving your thrift budget for vintage drapery rods or finials and investing in new, lined panels for a perfect fit and protection against UV damage.
Community Wisdom: Tips for Smarter Secondhand Shopping
- Always inspect fabric items for odors, stains, and the type of interior filling.
- For furniture and hard surfaces, choose solid wood, stone, or metal over plastic.
- Request documentation for any rugs or textiles—especially regarding origin, material, and exposure to pets.
- Be prepared to budget for professional cleaning or rewiring services when considering any complex vintage item.
- If replacing only the cover or shade, new inserts or hardware deliver the best mix of thrift value and safety.
