Key Features & Innovations

cUPC Listed

The Uniform Plumbing Code (cUPC) and American Society of Mechanical Engineers (ASME) are trade organizations that cooperatively meet to create mechanical design and test routines for plumbing products. These are trade organizations tasked with creating guidelines for safe and interchangeable products that provide value for consumers and competitiveness among manufacturers. All of LAUFEN Bathroom ceramic products (unless noted otherwise) meet the design requirements and laboratory testing demands of these organizations. Organizations that provide this testing routine include the International Association of Plumbing and Mechanical Officials (IAPMO Group), whom has issued several of LAUFEN’s certifications

ADA Compliant

The Americans with Disabilities Act (ADA) provides greater safety and comfort for individuals living with physical or challenging impairments. ADA regulations apply on both federal and state levels, however states have the ability to modify federal mandates or create their own codes. Due to the myriad variables associated with the plumbing industry, manufacturers such as LAUFEN do not have a singular agency that would issue a product as ADA-approved in that proper installation to the codes is a mandatory component of compliance with ADA rules. LAUFEN has designed certain products that we feel can become part of an ADA compliant bathroom when installed according to regulation. We have designated the ADA compliance of these products in our Price Guide with the ADA icon. While we believe these products will be acceptable for ADA installations, we cannot guarantee that the product will be found acceptable in all locations.
