III. User Needs Hierarchy Analysis (KANO Model)

3.1 Basic Needs (Must-Haves)

• Effective Waterproofing & Splash Protection: Core function: prevents water from splashing out of the shower area, keeping the bathroom floor dry.
• Size Compatibility: Curtain width and length must match the shower stall or bathtub dimensions to ensure full coverage.
• Easy Installation: Users expect to hang the curtain on the rod conveniently and quickly, without complex tools.

3.2 Performance Needs

• Easy to Clean/Machine Washable: Facilitates daily maintenance, reduces dirt and mold buildup, and maintains hygiene.
• Mold & Mildew Resistant, Antibacterial: Effectively inhibits mold and bacterial growth in humid environments, extending lifespan and maintaining health.
• Good Drape & Stability: The curtain should have sufficient weight, not easily flutter or cling to the body during showering, providing a comfortable experience.
• No Chemical Odor: Especially for new curtains, consumers dislike strong plastic smells and are concerned about environmental health.
• Durable Material: The curtain should withstand daily use and multiple washes without easily wearing out or tearing.

• Top Light-Transmitting Design: The top part of the curtain features semi-transparent mesh or light-transmitting material to increase light in the shower area while maintaining lower privacy.

• Unique Texture & Aesthetic Design: Features like waffle weave, linen texture, 3D pebble patterns, etc., enhance the overall bathroom aesthetics and style.

3.4 Unmet Needs & Market Gaps

• Actual Water Penetration: Some products claim to be waterproof, but water still penetrates under prolonged or high-pressure water flow, leading to damp bathroom floors.
  

  while some report it repels water and keeps water in the tub, others mention that water soaks through to the fabric curtain. // If something is touching the outside of the shower curtain while you are taking a shower, water will move through the curtain to that object then run down onto the floor. // I bought this shower stall curtain to replace my shower door. The color of this curtain is perfect! I ordered the lavender one, and the shade is soft and beautiful. The material is very sturdy and should last a long time. This curtain has magnets at the bottom, and the reinforced rings at the top are of excellent quality. The length is perfect for my shower stall, and this shower curtain is durable enough to withstand washing in the machine. I highly recommend this shower stall curtain, and I plan to order a few more in different colors. I strongly recommend this curtain from this seller.

• Insufficient Magnet Strength at Bottom: Magnets at the bottom of some curtains are not strong enough to effectively secure the curtain, allowing it to flutter or shift.
  

  Customers have mixed opinions about the shower curtain's magnet strength, with some finding them superb and working well in the tub, while others report that the magnets are horrible and don't stick to bathtubs. // The only small drawback is that because it's on the lighter side, it can shift around a bit if you don't have strong magnets or weights at the bottom. Not a huge issue, but something to note.

• Material Feel Doesn't Match Description: The actual feel of some fabric curtains is closer to plastic, falling short of advertised 'soft' or 'luxurious' claims.
  

  while some say it's better than plastic, others describe it as feeling like plastic rather than fabric. // Customers have mixed opinions about the material of the shower curtain, with some loving it while others find it more plasticky than fabric. // Customers have mixed opinions about the shower curtain's fabric, with some finding it nice and silky, while others describe it as cheap and bad feeling.

• Poor Quality Included Hooks: Plastic hooks included with some products are prone to breaking or appear cheap, affecting the overall user experience.
  

  Easy to install but the included hooks did look a little cheap so I just swapped them out for nicer ones and it improved the entire aesthetic. // The material quality and thickness receive mixed feedback - while some like the fabric, others find it extremely thin, and while some say it's water-resistant, others report water soaking through.

5.2 Competitive Landscape Observation

5.2.1 Market Maturity

5.2.2 Market Innovation Trends

VI. Market Fit Analysis

6.1 Alignment Analysis

6.2 Key Findings

• Users have extremely high expectations for actual 'waterproofing/water penetration resistance' and 'mold resistance & cleanability,' which some products fail to fully meet. Negative reviews often focus on poor actual waterproofing and mold issues, directly impacting brand reputation and repurchase rates, representing a key opportunity for product improvement.
• The line between decorative shower curtains and functional liners is increasingly blurred, with consumers seeking a combination of function and aesthetics. More 2-in-1 or design-focused waterproof curtains are emerging in the market. However, their core functional performance (waterproofing, mold resistance) remains the decisive factor, with aesthetics being a value-add.
• Innovative designs (e.g., hook-free, detachable liners, top light transmission) can significantly enhance user experience and create differentiated advantages. These design points effectively address user pain points related to installation, cleaning, and lighting, leading to higher satisfaction, premium pricing potential, and attracting consumers seeking convenience and quality.
• The 'sensory experience' of the material (e.g., odor-free, fabric-like feel vs. plastic, softness) is an important factor influencing user satisfaction. Emphasizing premium materials and eco-friendly, odor-free properties can effectively elevate the product's premium image, attract consumers focused on quality of life, and reduce returns due to odors.
