Why Does My New Glass Shower Smell Bad?

If you’ve recently had a beautiful new glass shower installed, you’re likely expecting nothing but luxury and a spa-like experience. So, when a sharp, vinegary odor hits your nose every time you step into the bathroom, it’s more than a little disappointing. You might even be asking yourself: Why does my new glass shower smell so bad?

Don’t worry—your shower isn’t broken, and the smell isn’t permanent. In fact, there’s a perfectly normal (and fixable) reason behind that not-so-fresh scent. Let’s dive into what’s causing it and how you can breathe easier, literally.

1. The Real Culprit: Silicone Sealant

That funky vinegar-like smell? It’s most likely acetic acid, a byproduct released by acetoxy-cure silicone, which is widely used to seal shower glass panels during installation.

• What is acetic acid? It’s the same compound that gives vinegar its sour tang.
• Why does it smell so strong? Silicone emits acetic acid as it cures. Since your shower is a small, enclosed area, the scent tends to linger longer than in larger rooms.
• Is it dangerous? Not typically. In well-ventilated areas, the smell is unpleasant but not harmful. However, extended exposure in unventilated spaces may cause eye or throat irritation​.

2. How Long Does the Smell Last?

If you’re wondering when you can enjoy your new shower without holding your breath, here’s what to expect:

• Strongest during the first 24 hours
• May linger up to 3–7 days, especially in bathrooms without windows or exhaust fans
• Lingering odors can also cling to bath mats, towels, and rugs

3. How to Get Rid of the Silicone Smell Faster

Don’t just wait it out—here’s how to speed up the process and freshen your space:

Ventilation is your best friend:

• Open windows and bathroom doors
• Run the exhaust fan for several hours a day
• Use a portable fan to circulate air out of the bathroom

Absorb odors with natural remedies:

• Place bowls of baking soda, white vinegar, or activated charcoal in the room
• Try essential oils like lemon or eucalyptus in a diffuser to mask the smell

Clean nearby surfaces:

• Silicone fumes may settle on nearby walls or counters. Wipe down tiles and glass with a water-vinegar solution to help neutralize lingering residue.

4. Other Causes to Rule Out

While silicone is the most common reason for post-installation odor, here are a few other culprits that may contribute:

• Trapped water or moisture under new caulking
• New grout or adhesives used in tiles or trim work
• Debris or dust from construction that hasn’t been fully cleaned

If the smell lasts longer than a week despite ventilation efforts, it might be time to have your installation team—like the experts at Alluring Glass—inspect for any overlooked material or improper sealing.

5. Should I Be Concerned Long-Term?

In most cases, no. The smell is temporary and part of the normal curing process of silicone.

However, if you:

• Have respiratory issues
• Experience irritation beyond mild discomfort
• Notice mold-like or chemical smells after the silicone odor fades

…then it’s worth consulting with your installer or a home expert to rule out more serious issues.
