Frameless Glass Shower Doors: Sleek Look but Worth It?

[yourdreamremodeling]

I really like the clean and modern feel of frameless glass shower doors. They make the bathroom look bigger and more open, which is exactly what I want. But I've heard they can be a bit high-maintenance when it comes to water spots and cleaning. For those who've installed them, do they stay looking good over time, or do they require constant upkeep?
