Bathroom openings in Santa Clarita are rarely standard — walls drift, curbs shift, and tile adds thickness that changes clearances from the rough frame. Custom frameless shower doors and enclosures fabricated and installed by Preferred Glass & Windows — AAMA-certified, no subcontractors, since 1969.
Bathrooms in this valley vary a lot by construction era. Compact alcove showers, corner neo-angle layouts, oversized walk-ins in newer builds, and original framed showers in 1970s and 80s homes that are out of plumb — we've done all of it. At Preferred Glass & Windows, every custom frameless shower door and enclosure is fabricated to the finished opening, not the rough frame. That's what makes the door seal correctly, swing cleanly, and stay aligned over time. We take every measurement in person before anything gets cut.
We fabricate from your finished surfaces so the final product fits the space you actually have. Configuration options include:
All glass is 3/8-inch or 1/2-inch tempered safety glass to meet California building codes. Clear, low-iron, and privacy patterns are available. Low-iron glass runs brighter and cleaner than standard clear, which makes a visible difference next to white tile or in bathrooms with strong natural light.
We stock heavy-duty hinges, handles, and sweeps in brushed nickel, matte black, and polished chrome. During installation, we map hinge placement against wall backing to prevent pulling over time and verify door swing clearance against vanities and toilets. If you're also getting a custom mirror, glass shelving, or a shower niche, we can handle it all in the same visit.
Preferred Glass & Windows has been a trusted provider in the Southern California area since 1969, and the team still handles every project in-house. We're AAMA-certified, fully licensed, and insured, and have been recognized by the LA Daily News and The Signal as the top glass company in the region. For custom frameless shower doors, that track record matters when the opening is out of square, the tile surround isn't plumb, or a high-finish primary bathroom won't tolerate gaps or misaligned hardware. If something isn't right, we fix it. Free in-home consultations and financing options are available for qualifying projects.
Most installs are completed in one day. Bathrooms with non-standard configurations or out-of-plumb walls may need extra time. We assess conditions before scheduling so there are no surprises on install day.
Yes. California building codes require tempered safety glass in wet areas including showers and tub enclosures. Every enclosure we install uses tempered glass as a baseline standard.
After tile and finish surfaces are complete. Fabricating to the finished opening, not the rough frame, is what makes the door fit and function correctly long term.
Most hinged and pivot doors use 1/2 inch glass. Sliding panels typically use 3/8 inch. The right choice depends on door size, hardware selection, and opening configuration. We walk you through the options during your consultation.
Use a squeegee after each shower to prevent hard water buildup on the glass. For deeper cleaning, white vinegar diluted in water works well on most glass surfaces. Avoid abrasive cleaners or anything gritty that can scratch the surface.
Wipe hardware down with a soft cloth and mild soap. Avoid abrasive cleaners on brushed nickel or matte black finishes. Dry metal surfaces after cleaning to prevent water spots and mineral buildup over time.
Yes. Older homes in areas like Saugus, Castaic, and Granada Hills often have bathrooms that are out of square or out of plumb. We fabricate panels to fit the actual finished space, so irregular layouts are not a problem.
I loved going with Preffered Glass as it was recommended by a family friend to fix my antique hutch cabinet. I spoke with Courtney and I needed 2 new pieces for my doors. She was great she got the measurements I needed and what I wanted. She got the work done same day. And when I installed the pieces one needed to be cut a little more because it was a little to big. She personally went to the back and cut the piece I needed so it can fit properly. 10 out of 10 recommend for all your Glasswork needs.
Preferred Glass & Windows is an amazing company to work with beginning to end on any project! Scott came to my house to give me a quote on shower doors for my master bath and on all my windows. He was extremely professional and helpful and made sure everything went smoothly! Courtney at the front desk was super friendly as well and very knowledgeable and she had no problem answering any of my questions! The customer service was top tier and the installation job was even better! I will definitely be a returning customer.
We had a broken window called for service to replace it. They came the next day measured the window said it would be a week or two to get the window call the next day. The window came in sooner than expected, they came that afternoon and installed it it came out great very impressed with their level of service. Thank you very much!!!
