On rain-pattern glass, find the textured face before you clean anything. Most shower installations point the pattern outward so the wet side stays smooth and squeegees clean in seconds. The patterned face collects splash and dust and gets a wash every week or two with soapy water and a soft brush worked along the vertical runs, then a blot dry.
Rain glass is rolled with an irregular vertical ripple that looks like water running down a window. Run a fingertip down both sides of the door. The rough side carries the pattern; the other is flat and takes a blade exactly like clear glass. Orienting the smooth face into the enclosure is the usual choice for a shower precisely because it keeps the hard-working surface easy to dry, while the ripple still does its distortion job from the dry side. If yours is reversed, the patterned-face routine below is the one that applies.
There is a second clue if touch leaves you unsure. Look at the exposed edge of the panel where the thickness shows: rolled glass has an uneven profile along that edge, and the wavy side is the patterned one. On a swing door, checking from outside while it stands open is easiest.
Squeegee top to bottom after every shower with overlapping strokes, and take the blade down the frame edge and along the bottom where water pools. Give it a proper wash weekly using a little dish soap in warm water, then rinse and dry it. That is the entire job. Because the wet side is flat, rain glass in this orientation is no more work than a plain clear panel while hiding far more of what is behind it, which is most of the reason people choose it.
The outside face sees splash from the sink, hairspray, dust and hands. Its vertical channels catch drips and hold them, so whatever lands runs downward and dries in a line. Wash it with soapy water and a soft brush stroked along the ripples rather than across them, since crossing the pattern skips the channel bottoms entirely. Rinse well, then blot with a towel. Avoid powders and pads here: the raised ridges dull first, and a stripe of dull relief is impossible to miss on a patterned panel.
How often depends on what else happens in the room. Where a vanity sits a step from the enclosure, the dry face collects toothpaste spatter and aerosol overspray, and both set harder than plain shower splash does. A shower in its own alcove may want this twice a year and no more.
Not nearly as plainly. The ripple already distorts everything behind it, so light spotting and early film vanish into the visual noise instead of standing out. That is a genuine advantage in a busy bathroom and a genuine trap in a neglected one, because buildup goes unnoticed until it has been there for months.
Yes. Patterned glass comes in the heavy tempered thicknesses frameless doors are built from, so it hangs on the same hinges and takes the same handles. Layout gets a little more attention, since the ripple runs vertically and a door sitting slightly out of plumb beside a fixed panel is easier to spot when there is a pattern to compare against.
A four inch sample tells you nothing about how much a vertical ripple hides across a whole door. Step back from a full enclosure display in our Lodi showroom, put yourself at the distance of your own bathroom, and the privacy question answers itself in about a minute.
