Bedside commodes are generally made from durable materials that are easy to clean and sanitize. The most common materials used in the construction of bedside commodes include: 

1. Steel: Many bedside commodes are made from steel, which is strong, durable, and resistant to rust and corrosion. Steel commodes are often powder-coated or chrome-plated for added protection and a sleek, modern look. 

1. Aluminum: Some bedside commodes are made from lightweight aluminum, which is also durable and corrosion-resistant. Aluminum commodes are often more expensive than steel commodes but may be a good option for patients who need a lightweight, easily transportable commode. 

1. Plastic: Some components of bedside commodes, such as the seat, backrest, or bucket, may be made from durable plastic. Plastic is lightweight, easy to clean, and can be molded into a variety of shapes and sizes. 

1. Rubber: Some commodes may have rubber tips or grips on the legs or handles to provide added stability and reduce the risk of slips or falls. 

The specific materials used in a bedside commode will depend on the manufacturer and the model, as well as the intended use and patient needs. Patients and caregivers should consult with their healthcare provider or medical equipment supplier to determine the best type of commode for their individual needs.
