When it comes to modern shower design, the material you choose matters—both for aesthetics and safety. At RennowPro, we’re not just glass suppliers; we know the “glass game.” In this post, we’ll explore why tempered glass is essential, reveal the critical difference between 3 mm and 5 mm thickness, walk you through why correct installation prevents shattering, outline different glass styles, and explain why RennowPro stands above the rest.
The Vital Role of Tempered Glass in Showers (and Full Disclosure on Safety)
Tempered (or toughened) glass is transformed through controlled heating and rapid cooling, producing a product significantly stronger than regular glass. For showers, this strength isn’t a luxury—it’s a necessity. Tempered glass resists the daily rigors of your bathroom—sudden temperature shifts, high humidity, and frequent impact—while offering a built-in safety feature: if it breaks, it shatters into small, cubed, dull-edged pieces, reducing the risk of laceration.
Why RennowPro Chooses Tempered Glass
- Safety first: From curious children to everyday users, safety is non-negotiable. Our tempered glass aligns with South African Bureau of Standards (SABS) requirements.
- Built to last: The tempered process ensures long-term performance even under daily wear.
Professional-grade: We ensure each panel is tested, certified, and delivered from the factory to your home with integrity.
3 mm vs 5 mm Glass: Why Thickness Matters (And Why RennowPro Uses Only 5 mm)
A quick search might reveal cheaper 3 mm shower panels—but there’s a reason RennowPro sticks exclusively to 5 mm:
Feature | 3 mm Glass | 5 mm Glass (RennowPro) |
Stability | Prone to flexing, risk of breakage | Rigid, less prone to deflection |
Installation rigor | Requires precise support | Forgiving yet strong |
Aesthetic | Slim, but fragile | Sleek and more robust |
Safety | Higher risk of shattering | Industry-standard tempered safety |
Thinner glass may save on cost but lacks the durability and confidence required in everyday use. By choosing 5 mm, RennowPro guarantees not only visual appeal but superior performance and a safer experience long-term.
Installation Done Right: Preventing Glass Shattering
Even the highest-grade tempered glass won’t perform if incorrectly installed. Faulty fittings, uneven surfaces, or improperly torqued hardware can introduce stress points—ideal grounds for cracks.
Pro Install vs. DIY Risks
- RennowPro offers certified installers—experts in ensuring correct placement, alignment, and allowance for expansion.
- Even something as minor as a slight misalignment or excessive pressure during installation can create tension—pressure points where cracks start.
Your Safety Net
- Training and tools: Our installers use the professional-grade tools and techniques needed for clean, stress-free installation.
- Clear instructions: Each RennowPro product comes with detailed, English-language instructions tailored to ensure a safe and resilient shower enclosure.
Exploring Varieties: Styles of Shower Glass
When designing or refurbishing your bathroom, glass style is a crucial design choice. Here’s a breakdown of popular finishes and their benefits:
By Shape and Structure
- Straight glass – Classic, clean lines perfect for minimalist designs. Ideal for creating an unobstructed, modern look.
- Curved glass – Elegant and space-saving, these create smooth corners and a more organic flow—great for circular or offset shower trays.
By Finish
- Clear glass – Transparent and timeless. Allows full light, making bathrooms feel spacious and bright.
- Frosted glass – Offers privacy while retaining a soft light. Perfect for shared or public bathrooms.
- Patterned glass – From geometric to abstract, patterns add texture and style while offering partial privacy.
- Obscure (etched) glass – Combines artistic flair with functionality; excellent for bathrooms that require discretion without sacrificing light.
- Tinted glass – Available in smoky greys or subtle colors for a hint of moodiness, flair, or luxury.
How RennowPro Stands Out
- Stylish selection: Whether your client wants minimalist clarity or decorative flair, RennowPro has a finish to match.
- Quality assured: No matter the look, every panel is tempered, SABS-certified, and crafted under rigorous quality control.
