Best Materials for Gym Lockers: Metal vs Plastic and Standard Locker Dimensions

Choosing the right gym lockers is an important decision for fitness centers, schools, recreation facilities, and athletic programs. Locker material affects durability, maintenance, security, and long-term cost. In this guide, we break down the best materials for gym lockers, compare metal vs plastic lockers, and outline standard locker dimensions to help you select the right option for your facility.

Common Gym Locker Materials

Most gym lockers fall into two main categories: metal lockers and plastic lockers. Each material offers distinct advantages depending on your environment, budget, and usage level.

Metal Gym Lockers

Metal lockers are one of the most common locker types used in gyms, schools, and athletic facilities.

Advantages of Metal Lockers

• Durable and impact resistant

• Cost effective for large installations

• Professional and traditional appearance

• Available in many sizes and configurations

• Easy to customize with locks and vents

Drawbacks of Metal Lockers

• Can rust in humid or wet environments

• Louder when opening and closing

• Requires regular cleaning to prevent corrosion

Metal lockers are best suited for dry locker rooms, school gyms, and facilities with moderate moisture control.

Plastic Gym Lockers

Plastic lockers are typically made from high density polyethylene (HDPE) and are increasingly popular in modern gym and aquatic environments.

Advantages of Plastic Lockers

• Waterproof and rust resistant

• Ideal for humid, wet, or poolside areas

• Quieter than metal lockers

• Easy to clean and maintain

Drawbacks of Plastic Lockers

• Higher upfront cost

Plastic lockers are ideal for health clubs, aquatic centers, locker rooms with showers, and high humidity environments.
