Can You Use Mason Jar Toothbrush Holders in the Shower?

Quick answer

Yes, you can use a mason jar toothbrush holder in the shower, but it's not ideal for the wet zone. Place it on a dry shelf or counter away from direct water spray to avoid water pooling and rust on the lid.

Diagnosis: Should your mason jar toothbrush holder live in the shower?

• Symptom: You want to keep your toothbrush within reach in the shower, but you're worried about water damage, rust, or the jar breaking.
• Likely cause: Showers expose the holder to constant moisture, which can cause water pooling inside the jar, rust on the lid, and an increased risk of slipping and breaking. If you notice water sitting in the jar or rust forming, that's a clear sign the location is too wet.
• Corrective action: Move the holder to a dry area like the bathroom counter or a shelf away from direct water spray. If you must keep it in the shower, place it in a dry corner and shake out any water after each use. Check the jar and lid weekly for moisture or rust; if rust appears, replace the lid or move the holder out of the shower.
• When to stop or choose another option: If you have young children, a very small bathroom, or a shower with no dry spot, consider a different material like a rust-proof plastic or silicone holder that's designed for wet environments. Your toothbrush holder should stay clean and dry—if it can't in your shower, choose a safer option.
