Great Day Appoints New CEO, Confirms Pullback From Bath Authority

Great Day Improvements announced Oct. 21 that Grant Davis will be the company’s new CEO, taking over for Drew Weinfurtner, who is leaving to pursue other entrepreneurial interests. Drew and Ed Weinfurtner, who recently announced he will retire as executive chairman, remain investors and will continue to serve as board members.

Davis has more than 25 years of experience in the home improvement industry. He has served as chief retail officer at Great Day since 2025. Prior to that, he was a senior vice president at the Andersen Corporation, following 12 years at Renewal by Anderson.

Great Day is the No. 4 company on Qualified Remodeler’s ranking of the industry’s largest firms, the Top 500. In 2025, it completed 100,742 jobs generating $1.7 billion in revenue. Great Day, which is home to several storied brands in home improvement, including Champion Windows & Doors, K-Designers, and Universal Windows Direct, among others, has steadily grown over the past decade through both acquisitions and organic growth. Its partner in that growth has been Littlejohn & Co., which owns a majority stake in the company.

Leadership transition

“We thank Ed and Drew for their leadership and the lasting impact they’ve had on Great Day,” said Steve Raich, managing partner at Littlejohn & Co., Great Day’s majority owner. “Grant is uniquely positioned to lead Great Day into its next chapter, bringing industry expertise, proven operational leadership, and firsthand knowledge of Great Day’s brands, people, and businesses. Littlejohn remains firmly committed to the company’s long-term strategy.”

The transition to Davis has been in the works for many months. He joined the company last fall as Chief Retail Officer and added responsibilities along the way. Davis is a friend and colleague of Great Day’s former CEO Michael Hoy going back to when they worked together at Renewal by Andersen. Hoy, who is also an owner, said that he is stepping down from the board, but will remain connected to the company as an advisor to Davis.

Bath authority update

Separately, the company confirmed that it stopped selling new jobs via its Bath Authority division in September, saying the division remains open as it completes all of its contracted work. It will also continue to honor all warranty work.

Great Day manufacturers nearly all of the products that it sells through retail. This includes, windows, doors and sunrooms, but did not include any of the bath products associated with The Bath Authority. Observers with direct knowledge of Great Day offered background information that purchasing bath supplies from a third party reduced the margins for that division, making it a natural place for the company to cut in an environment of rising prices and consumer uncertainty.
