1. Size matching: First, measure the size of your bathroom window or shower area to ensure that the length and width of the shower curtain you choose can fully cover it. Note that the length of the shower curtain should usually be long enough to prevent water from splashing when showering.

2. Material quality: A high-quality PEVA shower curtain should have a soft and smooth feel and a certain thickness and durability. Check the sewing process of the shower curtain to ensure that there are no thread ends or loose threads to avoid thread derailment during future use.

3. Color and pattern: Choose a shower curtain color and pattern that matches the bathroom decoration style. Consider the overall tone and style of the bathroom and choose a shower curtain that can blend in or contrast with it.

4. Easy to clean: Consider the easy cleanability of the shower curtain and choose a material and style that is easy to clean and maintain.

5. Hanging method: Choose a suitable hanging method according to your bathroom structure and personal preferences, such as hook type, magnet type or punch type.
