Short answer

The decomposition time of a shower curtain can vary depending on the material it is made of. However, on average, a typical plastic shower curtain can take several hundred years to decompose completely.


Shower curtains are commonly made of PVC (polyvinyl chloride), a type of plastic known for its low cost, durability, and water-resistant properties. However, over time, shower curtains can start to decompose due to several factors. Exposure to heat, sunlight, and moisture can cause the PVC material to break down, leading to deterioration and weakening of the shower curtain's structure. Additionally, the constant contact with water, soap residues, and mold might contribute to the degradation of the material.

As the decomposition process initiates, the PVC shower curtain may experience discoloration, becoming dull and faded. This change in appearance is often accompanied by a loss of flexibility. The plastic may become brittle, cracking and forming small holes or tears. These weakened spots allow water to leak through, reducing the effectiveness of the shower curtain in keeping the bathroom floor dry and protected from moisture damage.

Eventually, with further degradation, the shower curtain may lose its structural integrity entirely and become unfit for use. It might start crumbling into small pieces, further compromising its functionality. While PVC is not biodegradable, the broken-down fragments of the curtain can still end up in landfills or oceans, contributing to plastic pollution and harming the environment. Hence, the decomposition of shower curtains highlights the importance of proper disposal and consideration for more sustainable alternatives, such as fabric or biodegradable options.

Is it possible to recycle shower curtain?

Intresting facts

  1. Shower curtains are commonly made from polyvinyl chloride (PVC), a plastic material that takes a significant amount of time to decompose. This means that when a shower curtain is disposed of, it can persist in the environment for centuries, contributing to plastic pollution.

  2. In landfills, shower curtains can take up valuable space and can potentially release toxic chemicals during decomposition. PVC contains additives like phthalates and lead, which can be harmful to both human health and the environment if they leach into soil or water.

  3. Some types of shower curtains are marketed as biodegradable or made from more environmentally friendly materials, such as polyester or natural fibers like hemp or cotton. While these alternatives may decompose more quickly than PVC curtains, they still require proper composting conditions to break down efficiently.

  4. The actual decomposition time of a shower curtain depends on various factors, including the thickness of the material, exposure to sunlight, and environmental conditions. On average, it can take around 20-30 years for a PVC shower curtain to decompose in a landfill, while alternatives like polyester may break down slightly faster.

  5. To reduce the environmental impact of shower curtains, it is recommended to either choose more sustainable options like hemp or cotton curtains, or opt for reusable fabric shower curtains that can be washed and used again. By making conscious choices, individuals can contribute to minimizing plastic waste and promoting a more sustainable future.

Summary and final thoughts

The decomposition time of a shower curtain can vary depending on its material composition. Vinyl shower curtains can take several decades to decompose in landfills, contributing to environmental pollution. On the other hand, shower curtains made from more eco-friendly materials like polyester or nylon tend to decompose faster, taking around 1 to 2 years. Nevertheless, it is worth noting that decomposition can be influenced by various factors such as exposure to sunlight, moisture levels, and other environmental conditions. Therefore, it is advisable to opt for shower curtains made from sustainable materials and properly dispose of them to mitigate the negative impact on the environment.
