A shower enclosure is one of the few pieces of glass in a house that you stand inches away from every day, which means the things that go wrong with it are impossible to ignore. Water tracking out onto the floor. A door that catches on the frame. Hardware that has gone spotted and dull. Glass that has taken on a permanent cloudy film from years of hard water.
There are three basic ways to build one, and the choice affects cost, cleaning and how the bathroom reads more than most people expect.
Metal framing runs the full perimeter of the glass and door. It is the most economical option, it uses thinner glass because the frame carries the structure, and the seal against water is excellent because the frame gives water a defined path. The trade-off is that the frame is visible, and the channels collect soap residue that needs regular cleaning.
Framing around the stationary panels, none on the door itself. It sits between the other two on price and gives you much of the open look without the cost of a fully frameless build. A reasonable middle for most bathrooms.
Thick tempered glass held by minimal clamps and hinges, with no perimeter framing. It is the cleanest look and the easiest to wipe down since there are no channels to trap residue. It costs more, it requires heavier glass and precise hardware, and it is the least forgiving of an out-of-square opening, which is exactly why measuring matters here more than anywhere else in the house.

Very few shower openings are perfectly square. Tile work, settling and original construction all introduce small variations, and on a framed enclosure the frame absorbs them. On a frameless build there is nothing to absorb anything. The glass either fits the opening or it does not, and glass cannot be trimmed on site once it is tempered.
That is why every enclosure gets measured in person, in the bathroom, before anything is ordered. It is also why a frameless quote given over the phone should make you suspicious.
Arizona water is hard, and over years the mineral content etches into the glass surface. Early on it is a deposit and it cleans off. Eventually it becomes physical etching in the glass itself, and at that point no cleaner will restore it because there is nothing sitting on the surface to remove.
Glass that has reached that stage needs replacing rather than treating. Catching it earlier, and squeegeeing the panels after use, genuinely extends how long an enclosure looks new.
If the hardware and framing are sound and it is only the glass that has gone cloudy, scratched or cracked, the glass alone can be replaced. Same principle as a window: the structure stays, the consumable gets swapped.
