The bathroom window that faces the neighbor’s driveway. The sidelight next to the front door that shows the whole hallway. The shower that turns the bathroom into a stage. Every one of those is a privacy glass problem, and every one of them has a better answer than a towel over the rod or a peel-and-stick film that bubbles by summer. Privacy glass is ordinary glass with a texture or finish that scatters light, so the room stays bright but nobody outside can make out what is on the other side. The trick is choosing the pattern that hides enough without making the room feel like a doctor’s office.
We have cut and installed obscure glass for homes across Glendora, La Verne, San Dimas, Claremont, Covina, Azusa, Pomona, and Upland since 1989 — 36 years, family owned. This is the walk-through we give at the counter: the four patterns people actually choose, what each one is good for, and the details that matter before we cut it.
The short version
Frosted (satin) glass is the cleanest look and the most versatile; rain glass hides the most while keeping the most light; reeded glass is the modern designer choice; classic obscure patterns (pebble, hammered, glue chip) match older homes. Bathroom windows near a tub or shower and any glass in a door usually need tempered privacy glass. Send us a photo of the opening and we can quote it: (626) 335-2900.
How privacy glass works (and the one number that matters)
Clear glass lets light travel straight through, so your eye can reconstruct an image. Privacy glass bends and scatters that light with a texture rolled into one side of the sheet, an acid-etched or sandblasted satin surface, or a laminated interlayer. The sharper and deeper the texture, the more the image breaks up.
Glass suppliers rate that with an obscurity level, usually on a 1–10 scale, where 1 is nearly clear and 10 is a full blur even with an object pressed to the glass. That rating is the thing to ask about. A bathroom window over a tub wants an 8 or higher. A pantry door where you just want to soften the view of the shelves can live at a 3 or 4. Light transmission moves the other way: most privacy patterns still pass 80–90 percent of the light, which is why a frosted bathroom window is brighter than the same window with a blind.
The four privacy glass patterns we cut most
Frosted (satin / acid-etched)
A uniform, smooth, matte surface with no pattern. It reads as a soft white glow, hides shapes well at a distance, and looks right in every style of house from a 1950s Glendora ranch to a new build in Upland. Obscurity is around 6–8 depending on the etch. The two things to know: it shows fingerprints more than textured glass (there are coated versions that resist this), and objects pressed directly against it become visible, which is why it is a window and partition glass rather than a shower glass for most people.
Rain glass
A rolled texture that looks like water running down the pane. It hides more than frosted does — usually a 9 or 10 — and, because the texture is on one side only, the smooth side goes inside for easy cleaning. It is the most popular privacy pattern for shower doors and enclosures because it disguises water spots and soap film better than clear glass ever will. On a bathroom window it gives full privacy without a blind. Our guide to hard water spots on shower glass explains why textured glass hides them so well.
Reeded (fluted / ribbed)
Vertical ribs, usually a quarter-inch to a half-inch wide, that stretch and slice whatever is behind them into a moving blur. Reeded glass is the pattern designers reach for right now: cabinet doors, interior doors, sidelights, wardrobe doors, and room dividers. The privacy level is moderate, roughly a 5–7, and it depends a lot on distance: an object right behind the glass reads as stripes, while a person across the room becomes a shape. It is a great choice where you want privacy and visual texture, and a poor choice for a shower unless you are fine with a suggestion of a silhouette. Wide-reed and narrow-reed versions look quite different, so ask to see a sample of both.
Classic obscure patterns (pebble, glue chip, hammered, seedy)
These are the textures found in mid-century and older homes throughout the San Gabriel Valley: the small dimpled “pebble” pattern, the feathery frost of glue chip, the dented look of hammered glass. Obscurity varies by pattern (most sit at 7–9), and they are still made, which matters if you are replacing one cracked pane in a set of three and want it to match. If your house is one of the older Glendora homes with original windows, bring the old piece or a clear close-up photo and we can usually identify the pattern.
Side-by-side
| Pattern | Privacy (1–10) | Look | Best for | Watch out for |
|---|---|---|---|---|
| Frosted / satin | 6–8 | Soft, uniform glow | Bathroom windows, office partitions, cabinet doors | Fingerprints; objects touching the glass show |
| Rain | 9–10 | Water-run texture | Shower doors, tub windows, garage windows | Textured side collects dust if installed facing out |
| Reeded / fluted | 5–7 | Vertical ribs, designer | Sidelights, interior doors, wardrobe doors, cabinets | Silhouettes still read up close |
| Pebble / glue chip / hammered | 7–9 | Traditional texture | Matching existing windows in older homes | Some patterns only stock in certain thicknesses |
Where privacy glass belongs in a house
- Bathroom windows. The number one request. Rain or frosted, and if the window is within reach of a tub or shower, plan on tempered glass (more on that below). Swapping the pane is usually a glass replacement job that keeps the existing frame; our glass replacement cost guide covers what drives the price.
- Front door sidelights and door lites. Reeded or frosted keeps daylight in the entry without showing the hallway to the street. Glass in and beside doors generally has to be safety glass.
- Shower doors and enclosures. Rain glass for maximum privacy, frosted or a partial frosted band for a lighter look. Our comparison of framed vs. frameless shower doors explains which frame styles work with textured glass.
- Garage and side-yard windows. Anything facing a walkway or a neighbor’s window. Rain glass here doubles as a security measure: nobody can inventory the garage from the street.
- Interior doors, wardrobe doors, and pantry doors. Reeded and frosted panels let light through between rooms. Our guide to wardrobe and closet door options covers the frosted-panel sliders that have replaced mirrored doors in a lot of SGV bedrooms.
- Office partitions and storefront back rooms. Frosted film or frosted glass at eye level on a clear panel is the standard conference-room treatment. Business owners can start with our storefront glass guide.
Details to settle before we cut
Tempered or annealed?
Building code can require safety glass in specific spots: glass in doors, glass next to doors, large panes close to the floor, and glass in or near tubs and showers are the usual ones. Every pattern above is available tempered, but tempered glass has to be cut to size before it is tempered, so measurements need to be right the first time and lead times run longer. Our post on tempered and safety glass around the house walks through where it is required.
Which side faces out?
Textured patterns are one-sided. In a window, the smooth side generally faces the weather so dust and rain do not settle into the texture; in a shower, the smooth side faces the water for the same reason. Frosted glass is the exception: it is usually installed with the etched side away from the wet or high-touch side.
Single pane or dual pane?
Privacy glass goes into dual-pane units too. The textured lite is typically the inside pane so the pattern stays protected, and the unit is sealed the same as a clear one. If the window is a foggy dual-pane you were going to replace anyway, this is the moment to add privacy at the same time; see foggy double-pane windows: repair or replace for how that decision goes.
Film vs. real privacy glass
Frosted window film is a reasonable short-term fix on a rental or a window you plan to replace. It scratches, peels at the edges over a few SoCal summers, and the privacy is lower than etched glass because the film is thin. Real privacy glass costs more up front and then costs nothing again.
Quick answers
Can you see through privacy glass at night?
With the light on inside and dark outside, a person becomes a visible silhouette through most patterns, especially reeded and lighter frosted glass. Rain glass and heavier obscure textures keep the silhouette blurry. For a bathroom that faces a street or a neighbor, choose a pattern rated 9 or higher.
Is frosted glass the same as obscure glass?
Frosted is one kind of obscure glass. “Obscure” is the trade term for any glass that lets light through but blocks a clear view; frosted, rain, reeded, pebble, and glue chip are all obscure patterns with different textures and privacy levels.
Can privacy glass be cut to fit my existing window?
Yes. In most cases we replace only the glass and keep the frame, whether it is a single pane or a sealed dual-pane unit. If the window is in a door, next to a door, or close to a tub or shower, it will usually need to be tempered, which changes lead time but not the fit.
The bottom line
Pick the pattern by how much you need to hide, then by the look. Rain for the tub and shower, frosted for a clean modern window, reeded where you want design as well as privacy, and a classic obscure texture when you are matching what the house already has. Get the tempered question answered before anything is cut, and put the smooth side toward the water and the weather.
