Diamond Certified Researched Articles on California Shower Door Corporation

researched article

California Shower Door Corporation recently completed this patio rail project.

California Shower Door Corporation provides a variety of bathtub and shower enclosures for residential clients throughout the Bay Area. The company is a direct manufacturer of the Majestic and Regency shower enclosure systems, which are designed to maximize space and suit any shower area. It can provide materials on a will-call basis; perform standard and custom installations; and install mirrors, guardrails, windscreens, interior glazing systems, glass countertops and glass railing systems.

President/CEO Thomas J. Nolan started working at California Shower Door Corporation in 1981, became general manager in 1990 and took over ownership in 2005. Mr. Nolan says his company is one of the only businesses in the Bay Area that exclusively focuses on custom shower doors, which allows it to offer specialized expertise. “Other companies install shower doors as an adjunct to their business, but our niche has always been creating shower enclosures that best fit our clients’ needs.”

“We're an employee-owned company, so everyone has a vested interest in making sure our customers are happy and have a positive experience. We know how people want to be treated when they hire a contracting company, and our aim is to offer our clients the same level of service we'd like to receive.”

If you’re taking on a bathroom remodeling project, make sure you’re aware of all your customization options. Most industries are prone to changing over time, particularly as technological innovations take place. However, another way in which industries develop is more philosophical in nature. According to Thomas Nolan, CEO of California Shower Door Corporation in San Francisco, such a change has gradually come about in the bathroom remodeling business. “Our industry has undergone a significant philosophical shift over the last 25 years,” he says. “Whereas consumers were once told, ‘This is what we have to offer, so create your space based on the specifications that are available,’ the new approach says, ‘If you can envision it, we can make it happen.’ Everything has become more geared toward customization and conforming to consumers’ desires.”

Mr. Nolan gives an example of this new approach in action: “A while back, we were installing a steam enclosure for the shower in a master bathroom. With a steam enclosure, the glass has to go the full height of the room in order to create an enclosed area to hold in the steam. In the case of this particular job, the ceiling above the shower was sloped downward, which brought a concern that the shower door would hit it as it opened. In the end, we solved the problem by putting a transom above the door, which made the door lower than the ceiling and allowed it to open inward and outward without hitting anything.”

Mr. Nolan says his company’s willingness to work around the customer’s needs reflects a thoroughly contemporary attitude in the bathroom remodeling industry. “If this had happened 25 years ago, the customer would have been told, ‘In order for us to do this, we have to rip out your ceiling.’ In contrast, today they’re told, ‘It’s not a problem at all. We’ll find a way to make it work for you.’”

Few shower enclosure companies earn the prestigious Diamond Certified award, which means they've been independently rated Highest in Quality. Even fewer can also claim eight decades of industry experience, but that's exactly the case for California Shower Door Corporation. "We've been in business since 1935, which is a testament to our commitment to excellence," says CEO Thomas Nolan. "It takes a high level of expertise and dedication to customer service to maintain a good reputation for that amount of time, so that's something we're very proud of."

California Shower Door Corporation provides all types of bathtub and shower enclosures for residential clients throughout the Bay Area. The company can design shower enclosure systems to maximize space and suit any area; provide materials on a will-call basis; perform standard and custom installations; and install mirrors, guardrails, windscreens, interior glazing systems, glass countertops and railing systems, and more.

Unlike shower enclosure companies that hire inexperienced workers who lack professional motivation, California Shower Door Corporation's status as an employee-owned and operated firm means its technicians have a vested interest in ensuring high levels of customer satisfaction. "Everyone who works here is on the same page about making sure the business is successful," says Mr. Nolan. "Ultimately, our job is to provide positive experiences for our customers, and that's exactly what we do."

Another distinguishing attribute of California Shower Door Corporation is its involvement with several leading industry organizations, including the National Kitchen & Bath Association (NKBA) and the National Association of the Remodeling Industry (NARI). "As a member of these groups, we're able to further establish ourselves as a company that's fully committed to excellence," says Mr. Nolan. "Our clients really like that we promote high professional standards in every aspect of our operations."

Tom Nolan: Only in America

By James Florence, Diamond Certified Resource Reporter

SAN FRANCISCO — When Tom Nolan started working at California Shower Door Corporation as a teenager, the last thing he expected was to one day be its president and CEO. “It’s one of those ‘only in America’ stories, where the kid who starts out sweeping the floors winds up owning the company,” he says. “It began as a summer job during high school, and I continued part-time through college while I earned my master’s degree in psychology.
