Corporate philosophy

Quality is our highest priority!
For us, quality means beautiful product design combined with high-quality materials and outstanding functionality. Our partnership with Euroglas means that we can verify and guarantee the highest quality in raw glass. Moreover, we can look back to 135 years of experience in glass processing, so that we benefit from the highest level of expertise and professionalism.

The welfare of our workforce is important to us.
In particular, we value reliability, mutual respect, appreciation, kindness and trust. We are honest and open to one another, and we show mutual understanding and respect. Our managers work closely with your many different teams in production, administration and sales. By cultivating openness and honest communication, we create a positive working atmosphere where everyone is both challenged and encouraged.

What distinguishes us from others is our customers.
They are our top priority, and we always find customised solutions for every specialised request. This includes personal consultancy and the creative implementation of modern glass products, so that every home becomes something very special.

We take responsibility for our products.
Glass is a sustainable material that is fully recyclable and can be reused any number of times without losing its quality. Furthermore, it is made almost exclusively from natural raw materials that occur abundantly in the natural world. Also, the materials we use for finishing, e.g. SpriColor paint, are 100% solvent-free, recyclable and free from heavy metals and from additives that are subject to labelling. We therefore combine ecological awareness with timelessness, modernity and quality. Join us as we look to the future!


History of Joh. Sprinz GmbH & Co. KG

SPRINZ Unternehmensgeschichte Timebeam

Our company, which is now called Joh. Sprinz GmbH & Co. KG, was started on 12 March 1886 by Johann Sprinz at Ravensburg, laying the foundation for a long-established, medium-sized and owner-operated family business. Originally founded as a grocer’s business, the company has since then grown, first into a glass wholesaler and eventually an all-inclusive glazing supplier.

Back in 1948, the company would deliver 1.5 tonnes of glass per day on its first lorry, an Opel Blitz. Today, it turns about 110 tonnes of raw glass into shower enclosures, glass doors, partition systems, façades and other specialised, high-quality glass products on a daily basis. This makes SPRINZ one of the leading glazing specialists in Germany. Now in its fourth generation, the family business still lives and works with glass, combining experience with innovation and high-tech with craftsmanship.

Since 2008, the company has also been supplying raw glass of the highest quality, in partnership with the glass manufacturing company Euroglas near Magdeburg. Everything is made in Germany and comes from a single source – from the raw materials and the initial idea to development and production.

Today, SPRINZ has a workforce of around 380 at its plants at the company's headquarters in Grünkraut, near Ravensburg, southern Germany. Ranging from the original idea to development and production, the good qualities of German craftsmanship are clearly in evidence in our bathroom furniture, component retailing, interior and exterior design, structural glass, insulating glass, the glass world of the kitchen and a showroom called World of Glass. This ensures customers receive consistently high quality, flexibility, distinctive innovative products, beautiful design, inspiring solutions, meticulous workmanship, customised solutions and fast, reliable service.
Firmly established in the region, the company sells its branded products throughout Germany via specially accredited dealers, and also has a strong international focus.

SPRINZ has created a name for itself with its World of Glass showroom. The showroom displays practical examples of different glass applications and also serves as a centre for innovations and a venue for seminars.

Facts & figures

SPRINZ Unternehmensgeschichte Facts

SPRINZ makes toughened safety glass, laminated safety glass and insulating glass and enhances its glass products with motifs and patterns as well as with slip-resistant and water-repellent surfaces. One speciality is high-quality ceramic screen printing on glass, used to create vivid colours and motifs. SPRINZ is the only company in Germany that carries out four-colour ceramic screen glass printing in photo quality.

Our glass products can be used in both interior and exterior design. By featuring, for example, real glass showers, mirrors, bathroom furniture and partition systems, SPRINZ covers a wide product range for bathrooms.
The focus is on frameless real glass showers with hinges flush on the inside. SPRINZ started to include special shower enclosure hinges – flush with the inside surface – as early as 1997. This fitting technology, which ensures quick, easy cleaning, has become the standard in recent years.

In addition to its main focus – the bathroom – SPRINZ’s portfolio includes quite a few further glass products for all spheres of life, and this is underlined by the company’s mission statement, “Living with Glass”. Glass doors and matching systems for sliding doors, kitchen rear panels and worktops as well as all-glass systems for the private and public sectors, glass staircases, façades and glass privacy screens – everything is possible with us.

All our glass products are characterised by design and innovation. The iF Design Award, Plus X Award, Design Plus Award and a nomination for the German Design Award are just some of the distinctions that SPRINZ has received over the last few years.
