Located just off Veterans Memorial Highway on 5th Avenue, the California Closets Ronkonkoma Office and Manufacturing Facility is convenient for customers living in western Suffolk County.

While our California Closets location in Ronkonkoma is not a showroom, it is where the magic that creates your custom-designed system happens. Once you’ve visited one of our 120 showrooms and worked with a member of our team to create your one-of-a-kind closet, pantry, entertainment center or home office design, the team here builds it. Utilizing the best CAD and CAM technology and equipment, we are an industry 2.0 business that maintains the highest standards of building your system to exact specifications.

Design Process

My experience with California closets was amazing! I had a Murphy bed built.  All the staff  that I worked with  were great. They built  me exactly what I was looking for! I love it! I would highly recommend them to both my family and friends!
