Common sealing methods include elastic openings or cuffs (often with latex or non‑latex straps), medical‑grade adhesive on site‑specific patches, and manufacturer patented watertight seal designs.

Both are available: many vinyl or plastic cast covers are reusable and easy to clean, while some adhesive patches, padding, and other items are intended to be disposable and single‑use.

Products are listed for pediatric (children) sizes, adult sizes, and some items are labeled as suitable for all ages.

Care varies by product: many reusable covers can be wiped clean or washed with soap and water or mild detergent, while disposable patches should be discarded after use. Some items list no specific care instructions.

Adhesive shower patches are small, transparent film pieces with medical‑grade adhesive and a release tab for site‑specific, usually single‑use protection. Wrap‑style covers are larger vinyl or plastic sleeves that slip over a limb, form a watertight seal with elastic or straps, and are typically reusable.
