How We Reviewed
Where our data comes from
We gathered data from reliable online retailers, manufacturer websites, and customer reviews. Product specifications were checked for accuracy and consistency. We focused on extension cords specifically designed for bathroom use.
How we built this shortlist
Initially, we looked at over 20 extension cords. We filtered them down to 8 options based on their relevance for bathroom use, including safety features and length. Each product was compared to find the best features.
What we ruled out and why
Products lacking safety certifications or reviews indicating poor performance were removed. We avoided cords that had less than 6 feet of length. Other products were excluded for not having sufficient outlets for multiple devices.
What we did not do
No hands-on testing was performed. We did not take lab measurements or create scores for the products. All information is based on research from verified sources.
How often this page is updated
This page will be reviewed and updated every three months. New products will be considered for addition, and existing recommendations will be checked for current information.
What to look for
Safety Certifications
Always look for extension cords that have safety certifications like ETL or cETL. These labels ensure the product meets safety standards. This is very important for bathroom use, where moisture can increase the risk of electrical shock.
Cord Length
Consider the length of the extension cord. A longer cord can provide flexibility in placement. A good rule of thumb is to choose at least a 10-foot cord for bathrooms. This allows you to reach outlets without clutter.
Number of Outlets
Think about how many devices you will plug in. A power strip with multiple outlets is very useful in the bathroom. Aim for at least 4 to 8 outlets to accommodate various devices like hairdryers and shavers.
USB Ports
USB ports offer a convenient way to power devices without needing extra adapters. Look for extension cords with USB-A or USB-C ports. Having these can make it much easier to charge phones or other gadgets.
Flat Plug Design
Flat plug designs can save space and reduce cord visibility. This is particularly useful in tight spaces like bathrooms. A flat plug can often fit behind furniture or along walls, keeping your area tidy.
How to Choose Extension Cords
Consider Your Power Needs
Think about how many devices you will use at once. A good rule is to have a power strip with at least 4 outlets for a bathroom. This ensures you can safely run multiple devices like hair dryers and straighteners.
Look for Waterproof Features
Since bathrooms can be humid, opt for cords with waterproof features. This protects against moisture damage and reduces the risk of electrical issues. Ensure the cord is rated for outdoor use or has a waterproof rating.
Check for Surge Protection
Surge protectors can prevent damage to your devices. Look for power strips that have built-in surge protection. This feature is important in a bathroom where electrical surges can happen.
Evaluate Cord Thickness
Thicker cords are generally safer and can handle more power. Look for cords with a gauge lower than 16 AWG for consistent performance. A thicker cord also means less chance of overheating.
Choose a Suitable Length
Select a cord that is long enough for your layout. For most bathrooms, a 10-foot extension cord provides enough length. This allows you to position devices where you need them without creating hazards.
