Everything You Need to Know
to Find the Perfect
Shower Door
A shower door is used 7,300 times over a decade. Five decisions determine whether those interactions feel right — or feel like a daily reminder of a specification mistake.
01
Configuration
What Does Your Bathroom's Geometry Allow?
Before considering glass, finish, or price, determine which door configurations are physically possible in your space. Bathroom geometry is a hard constraint — a door that requires 28 inches of swing clearance doesn't become viable because you prefer the aesthetic.
| Configuration | Model | Opening Range | Key Advantage | Clearance Needed |
|---|---|---|---|---|
| Barn-style sliding | UKS04 | 50–65 in. | 90–95% entry, no floor track | None |
| Double bypass sliding | UKD01 | 56–72 in. | Opens left / right / center | None |
| Three-panel bypass | UKS13 | 46–60 in. | 33% more entry than standard bypass | None |
| Frameless swing | UKH07 | Per layout | 100% entry, zero floor hardware | 24–28 in. |
| Bi-fold | UKH10 | Per layout | Full entry, folds inward | None outward |
| Custom | Made to measure | Any | Quote in 2 hours | Any |
02
Glass Specification
Thickness, Certification, and Clarity
Glass specification is the decision most buyers skip and the one most determining how the door performs over a decade. For any frameless door wider than 48 inches, one number matters above all others.
| Glass type | Iron oxide | Tint | Transmittance | Best for |
|---|---|---|---|---|
| Standard clear | ~0.1% | Faint green at edges | 82–84% | Neutral tile, standard lighting |
| Optiwhite low-iron | <0.01% | None | 91% | White tile, stone, warm lighting |
SGCC certification means an independent laboratory — not the manufacturer — tested the glass against ANSI Z97.1. Either listed at safetyglazing.org or it isn't. All Unikoo frameless doors carry both certifications.
03
Hardware Grade
What Lasts the Decade?
Shower door hardware operates in a sustained humid environment with daily mechanical use. The material specification determines the outcome in year three, not year one.
| Material | Corrosion resistance | Timeline | Verdict |
|---|---|---|---|
| Zinc alloy + chrome plating | Low — plating wears through | Visible degradation: 3–5 years | Avoid |
| 304 stainless steel | High — residential appropriate | No degradation in standard use | Acceptable |
| 316 stainless steel | Highest — molybdenum resists chloride | No degradation — marine grade | Specify this |
04
Coating
Is Maintenance a Preference or a System?
Uncoated glass accumulates mineral deposits that bond to the surface within 4–8 weeks. EnduroShield fills those micro-pores at the factory — water beads off instead of drying in place. The numbers tell the rest.
| Task | Uncoated glass | EnduroShield — both sides |
|---|---|---|
| Weekly cleaning | 15–20 min | 3–5 min |
| Monthly deep clean | 20–30 min | None required |
| Annual mineral removal | 2–3 hours | 30–45 min |
| 10-year total | ~220–260 hours | ~30–50 hours |
05
Delivered Cost
What Does the Door Actually Cost at Your Door?
The price on a product page is not the delivered price. Three variables — sales tax, freight, and the specification premium built into retail margins — determine what you actually pay.
| Cost component | Showroom | Big-box retail | Unikoo direct |
|---|---|---|---|
| Unit price (60" frameless) | $950–$1,200 | $700–$900 | $650–$720 |
| Sales tax (8.25% TX) | $78–$99 | $58–$74 | $0 |
| Freight + liftgate | $100–$200 | $0–$100 | $0 |
| Total delivered | $1,128–$1,499 | $758–$1,074 | $650–$720 |
