My Shower Door Wins Award for Innovation

Inc. Business Media, which produces Inc. Magazine, has named a pair of Fort Myers-based family businesses to its prestigious Inc. 5000 list, honoring and celebrating the country’s fastest-growing, privately held companies.

MY Shower Door was recognized for the ninth time in 11 years, and D3 Glass has made the list for the third consecutive year. Both companies are owned by the Daubmann family, entrepreneurs who have grown their local businesses into thriving companies serving commercial and residential customers across Florida and beyond.

“Our success proves that Southwest Florida, and Lee County in particular, offers fertile ground for entrepreneurs with a good idea and solid business plan,” said Bill Daubmann, president of MY Shower Door and D3 Glass. “It’s difficult for any business to grow, and even more challenging to sustain that growth over time. The Inc. 5000 list includes some of the biggest brands in America – like Microsoft, Meta and Under Armour – and to be mentioned alongside those companies is a tremendous honor for our team.”

The Daubmann Family

The Daubmanns founded MY Shower Door in 2003. The company designs, manufactures, installs, and warranties frameless shower doors and enclosures. In addition to its manufacturing facility in South Fort Myers, MY Shower Door has 10 showrooms in North Naples, South Naples, Fort Myers, Cape Coral, Sarasota, Tampa, Pinellas Park, Orlando, Boca Raton, and Charlotte, N.C. It also operates a Naples showroom for MY Architectural Glass, allowing customers to see, feel, and touch glass and hardware before moving forward with wine closets, glass railing systems, and glass office partitions.

Inc. ranked MY Shower Door at No. 4,697 on its Inc. 5000 list. It was ranked No. 8 in Southwest Florida, No. 409 in Florida, and No. 308 nationally among companies in the construction business.

In 2012, the Daubmanns established D3 Glass as a separate entity specializing in the fabrication, tempering, and lamination of glass. The business supplies glass to MY Shower Door, as well as to outside builders, contractors, and property owners.

D3 Glass was ranked No. 4,891 on the 2025 Inc. 5000 list. It was ranked No. 11 in Southwest Florida, No. 436 in Florida, and No. 149 nationally among manufacturing companies.

Bill and Donna Daubmann, along with their sons, Keith and Doug, lead company operations. Combined, the businesses employ 181 individuals across all locations.

“When we started MY Shower Door, it was a true family business with just our immediate family and a few others,” Bill Daubmann said. “Today, our company is predominantly non-family members, but we still run it like a family business by treating employees well and staying true to our values, focusing on exceptional products and five-star customer service.”

The Inc. 5000 List

“Making the Inc. 5000 is always a remarkable achievement, but earning a spot this year speaks volumes about a company’s tenacity and clarity of vision,” added Mike Hofman, editor-in-chief of Inc. “These businesses have thrived amid rising costs, shifting global dynamics and constant change. They didn’t just weather the storm – they grew through it, and their stories are a powerful reminder that the entrepreneurial spirit is the engine of the U.S. economy.”

Inc. 5000 honorees will be recognized during a conference and gala held Oct. 22-24 in Phoenix, Arizona.
