Choosing a frameless shower door comes down to four decisions. Get those four right and the rest — finish color, height option, handle style — is personal preference. Skip one and you end up with a door that looks right in the product photo and doesn't fit, doesn't function, or doesn't hold up in the opening you actually have.
This guide works through each decision in order, with the specification benchmarks that separate adequate from excellent, and a 30-second selector at the end that routes you to the right Unikoo model for your bathroom.
Decision 1: Opening Width — This Determines Which Models Apply
Measure your shower opening at three heights: 6 inches from the floor, at mid-height, and 6 inches below your intended door top. Use the smallest measurement as your ordering dimension. Walls are rarely perfectly parallel — a door ordered to the widest reading won't seat correctly at the narrowest point.
| Your opening width | Recommended model | Configuration | From |
|---|---|---|---|
| 46–60 in. | UKS13 | Framed 3-panel bypass | 620 |
| 50–65 in. | UKS04 | Frameless barn sliding | $650 |
| 56–72 in. | UKD01 | Frameless double sliding | $720 |
| Any width + swing space | UKH07 | Frameless swing / hinged | Per config |
| Non-standard size | Custom | Made to measure | Quote in 2hrs |
Decision 2: Sliding vs. Swing — This Determines Your Configuration
The choice between a sliding and swing door isn't primarily aesthetic — it's determined by your bathroom's floor plan and how much clearance exists outside the shower opening.
Decision 3: Glass Specification — This Determines Long-Term Quality
Glass specification is the decision most buyers skip, and the one that most determines how the door performs over time. Three elements matter: thickness, certification, and coating.
3/8 in. (10mm) is the correct specification for any frameless door wider than 48 inches. A 60-inch panel in 6mm glass deflects ~65% more than in 10mm under equal load — that flex is the hum you feel when a cheap door closes.
SGCC (Safety Glazing Certification Council) is independent third-party verification that the glass meets ANSI Z97.1 safety standards. "Tempered glass" without SGCC is a manufacturer's own claim — no independent test confirms it.
EnduroShield is a factory-applied permanent hydrophobic coating that fills microscopic surface pores — water beads off instead of spreading and drying. Uncoated glass develops visible soap scum within 4–8 weeks of daily use. The coating doesn't wear off and requires no reapplication.
Decision 4: Hardware Finish — This Is Personal Preference (With One Rule)
Finish choice is the most personal of the four decisions — but it has one objective rule: match your existing bathroom hardware. The shower door hardware finish should align with your faucet, towel bar, and cabinet pull finish. A deliberate contrast (Matte Black door hardware against Brushed Nickel faucets) can work as a design choice. An accidental mix doesn't.
