Choosing the right manufacturer involves several key factors: material quality, customization options, ease of maintenance, and safety compliance. Start by considering the volume of traffic your restroom will experience and select durable materials like compact laminate or stainless steel. Ensure the manufacturer offers custom designs to fit your space's specific dimensions and style. Prioritize easy-to-clean surfaces and safety features like anti-slip floors and secure locks. Lastly, look for a manufacturer with a solid reputation, positive customer reviews, and excellent after-sales service.
