The Bathroom Association has welcomed Addmaster as a new Affiliate Member, strengthening the Association’s growing network of specialist suppliers supporting better bathrooms for people and planet.
Addmaster (part of Polygiene Group) is a leading supplier of antimicrobial additive solutions, including Biomaster, a silver-ion-based antimicrobial product protection technology designed to be incorporated into materials during manufacture to deliver built-in, long-lasting protection.
Why antimicrobial product protection matters in bathrooms
Bathrooms and washrooms are naturally high-risk environments for microbial growth: heat, humidity, splash zones and frequent touchpoints make many surfaces prone to microbial build-up, which can also contribute to staining, odour and material degradation over time.
Addmaster’s washroom-focused guidance highlights that using antimicrobial additive technology can reduce microbial load, helping to protect products from deterioration, reduce staining, and combat odour, thereby supporting a more hygienic and pleasant washroom environment.
Biomaster is designed to be used across a wide range of bathroom-relevant applications and materials, including sanitaryware, ceramic tiles, taps and shower heads, shower curtains, sealants and grouts, as well as plastics, paints and coatings commonly used across bathroom components and interiors.
Daphne Doody-Green, CEO of the Bathroom Association, said: “We’re delighted to welcome Addmaster to the Bathroom Association. Bathrooms are demanding environments, and Addmaster brings deep expertise in antimicrobial product protection to help our members design and manufacture products that stay cleaner and fresher for longer.
“Their specialist technology, built into materials at the point of manufacture, offers an important additional layer of reassurance for consumers while also helping protect surfaces; a win for customers and the fight for improved hygiene.”
Paul Willocks, global marketing director for the Polygiene Group, commented: “Joining the Bathroom Association matters because it’s where the industry comes together to raise standards, share insight and shape what’s next. As part of this community, Addmaster can collaborate with manufacturers across the sector to help them tackle a real-world challenge in bathrooms: microbial build-up in hot, humid spaces. We already work with leading bathroom manufacturers, and this collaboration further cements our position as a trusted antimicrobial partner within the industry.
“Members can gain access to expertise, connections and collective influence, and we’re excited to contribute proven antimicrobial product protection know-how that can support better-performing bathroom products and stronger end-user confidence.”
