Koralle Sanitary Products

What Koralle Sanitary Products does

Koralle Sanitary Products, operated by Kermi Duschdesign GmbH, is a German manufacturer of premium shower enclosures and bathtubs/trays headquartered in Plattling, Germany, and a member of the Swiss-listed Arbonia Group (SIX: ARON). Founded in 1973 and marketing under the "Koralle" brand, the company has delivered bathroom products to the German, Austrian, and Swiss markets for over 50 years, with a portfolio spanning 12+ shower enclosure series (e.g., S800, S808, SL450, myDay, myDay Comfort, X88 Free, Twiggy Plus, Twiggy Top) and four bathtub/shower tray families (T200, T350, T400, T700/T750) covering configurations from quadrant and corner to freestanding and barrier-free floor-level installations.

Underlying technology centers on glass, acrylic, and mineral-casting materials with engineered hardware including sliding, pivot, fold, and walk-in mechanisms; lift-and-lower (Hebe-Senk) profiles; proprietary coatings such as GlassPlus and Satinato; and in-house Maßanfertigung (custom cut-to-measure) production. Products carry a 5-year warranty on shower enclosures and a 10-year warranty on acrylic tubs, both materially exceeding German legal requirements, and have been recognized with German Design Awards every year from 2016 through 2022, plus iF Design, Red Dot, and Good Design awards.

Koralle generates revenue through one-time product sales of standard catalog items and bespoke Maßenfertigung units, priced via a downloadable but not publicly itemized price list (latest: 2026) and transacted exclusively through the qualified Sanitärfachhandel (sanitary specialist trade) channel in DE/AT/CH. The specialist trade provides consultation and professional installation through its own installation businesses or via Koralle's own service team, supplemented by an in-house Verkaufsberatung sales advisory function. End customers are predominantly private residential remodelers and homeowners seeking design-oriented, accessible, or custom-sized bathroom solutions.
