Curbless vs threshold showers with glass
How to control water on a flush entry — and when a curb is simply the smarter dam.

A curb is a simple and very reliable dam. A curbless entry looks calmer and walks better, but water there is held by correct slopes and a well-placed drain rather than by the structure. That choice has to be made before tile, because the base cannot be redone later.
A classic two to four inch curb forgives a lot: a slight slope error, a powerful head, kids who splash. Glass on a curb sits on a flat surface, the sweep compresses along a straight line, and water physically cannot leave the zone.
A curbless build demands discipline. Slope must be real and directed to the drain, not "generally toward the middle." A linear drain is often added at the entry or near the head to intercept flow before it reaches the dry side.

Glass behaves differently in a curbless scheme. The bottom gap is kept minimal but it exists — a panel cannot stand in water. That makes spray direction critical: if the head faces the entry you need an extra panel or the shower turned inward.
For accessibility, curbless is nearly the only answer: wheelchairs and walkers will not clear a curb, and stepping in without a lip is safer at any age. Here it pays to make the opening wider than the standard 24 inches and to use a fixed panel instead of a door.
Vireo Glass matches the glass configuration to your chosen floor scheme once details are approved: entry type dictates seals, panel position, and whether a return wing is needed. Panel options are under glass partitions and the workflow on measure and install.
