The glass in a shower enclosure is measured in millimeters. You can find glass enclosures with 4mm thick glass. Some models are designed with a locking glass door or an icy glass door.

For example, a framed-glass shower enclosure will have an unframed, curved design, and is usually installed with a less than perfect fit.
