Securit Safety Glass: What Thickness to Choose for a Shower Cabin and Why Avoid Acrylic "Glass"

Certification or compliance with standards is not a decorative detail. It is the way in which the manufacturer declares that the glass and the product have been manufactured and tested according to specific requirements.

In glass, the standard often associated with thermally toughened safety glass is EN 12150. This relates to the glass itself as a material: processing, tolerances, breakage, physical and mechanical properties. In shower cabins, on the other hand, we are also interested in the product as a whole: that is, how the cabin behaves, how it is supported, how stable it is and how it responds to use. There we find specifications concerning cabins as a product, such as EN 14428.

For the owner, the practical conclusion is simple: we don't buy anonymous "glass" for a shower without knowing what it is. We require a cabin or glass from a serious supplier, with a clear indication that it is safety glass, suitable for use in showers. If it is custom made, the glazier or supplier must know exactly the usage and recommend the correct thickness and support.

6mm is common in many prefabricated shower enclosures, especially when there is a metal frame. In a classic sliding, semi-circular or corner cabinet with a profile, 6mm can be a perfectly reasonable choice, as long as the product is of good quality and the glass is safety.

The advantage of 6mm is that it keeps the weight and often the cost down. This is important in standard cabins, where economy and practicality are key criteria. Not every bathroom needs to have 10mm glass to be safe or proper.

The downside is that the feel can be "lighter". In large sheets or frameless applications, 6mm is usually not the choice that will give premium sturdiness. If one wants a large stable divider or a clean frameless effect, one usually looks further up.

8mm is for many applications the golden ratio. It gives a noticeably more robust feel than 6mm, without always reaching the weight and cost of 10mm. It is a very common choice for fixed panels, quality cabins, semi-frameless solutions and several small or medium-sized frameless applications.

In a fixed shower partition, 8mm can provide a good sense of security and a clean aesthetic, especially if there is a correct floor or wall profile and suitable support bracket. It is not an exaggeration, but not an economic minimum solution either. For many Greek bathrooms, it is the most logical choice when we want something of quality without going to custom excesses.

If the fixed panel is relatively large or if the cabin is very minimal, the support must be considered properly. 8mm is not licensed for rough installation. It needs proper supports, good screws, proper anchoring and attention to whether the wall can take the load.

10mm gives a very solid and premium feel. It is often found in large frameless constructions, fixed panels of larger dimensions or more luxurious applications. When you grab it or when a large door opens, the difference in feel is obvious.

But 10mm also has requirements. It is heavier, costs more and needs stronger components. On hinged doors, the hinges must be suitable for the weight. In fixed panels, the support must be correct and not just "a profile on the wall". If the wall is plasterboard or flimsy construction without reinforcement, weight becomes a serious issue.

10mm makes sense when dimension, aesthetics or construction require it. It doesn't have to become an end in itself. For many home cabs, a properly mounted 8mm makes more sense than a heavy 10mm mounted with insufficient support.

A fixed divider does not just mean a glass that stands on its own. It needs proper support on the wall, floor or base, and often a stabilizing arm. The larger the crystal, the more important the support becomes.

A reasonably dimensioned 8mm fixed panel can be very safe and sturdy if properly supported. But if it is too long, too high, or exposed without sufficient arm, it can have unwanted movement. The glass should not "play" when you touch it or when you open the cabin door.

The quality of placement is critical. A wall with loose substrate, poor anchoring or incorrect drilling can invalidate even the best glass. If it is plasterboard, reinforcement must be provided in advance. We cannot rest a large security crystal on a random frame or flimsy substrate.

In safety glass, edges are not a detail. They must be properly machined, polished and fit for use. Acne is a sensitive spot. A hit on the edge can be much more dangerous to a thermally toughened glass than a simple hit in the center of the surface.

That is why shower cabins must have glass made for this use. We do not take any glass and "cut" it roughly. After heat hardening, the glass is not cut or drilled. All holes, notches and dimensions must be provided before curing.

This is yet another reason custom cabs need a proper measurement by a professional. A mistake in dimension is not easily corrected afterwards.

Yes, but they are limited. Acrylic can make sense in very economical, temporary or lightweight solutions. It can also be used in cases where the weight must be kept very low or where the construction cannot accept glass. But this is not the same as a normal, quality shower cabin.

For a master bathroom, where we want durability, a clean look, and a good feel, acrylic is usually a compromise. It may drop the initial cost, but it often loses out on looks and durability.

If the budget is limited, it is better to choose a simpler cabin with 6mm safety glass and frame, rather than a cheap solution with an acrylic panel that will quickly look tired.

The thickness of the glass affects the cost, but it is not the only factor. Dimensions, custom, thickness, processing, holes, fittings, anti-lime coating and placement also count.

For a fixed panel or a good frameless solution, the cost should not be judged only by the square of the glass. Correct supports, measurements, edges and placement are part of the value.

Before ordering a cabin or fixed partition, it is worth asking for specific information. You don't need to become a pattern expert, but you do need to know what you're buying.

The first mistake is to treat glass as a simple "glass". We don't want any glass in the shower cabin. We want safety glass, properly processed and fit for use.

The second mistake is choosing thickness based on price alone. A very economical 6mm might be fine in a framed cabin, but not necessarily in a large frameless panel. Accordingly, a 10mm may be impressive, but not needed in a small application or require stronger support.

The third mistake is choosing acrylic because it "looks like glass and is cheaper". It may seem reasonable at first, but in a bathroom that gets used every day, scratches, dullness and a plastic feel quickly show up.

In a small bathroom with a ready sliding cabin and a full frame, a 6mm safety glass can be a perfectly reasonable choice. The frame helps with support, the weight stays in check and the cost remains affordable. If the product is of quality, we don't need to chase a bigger thickness just for an impression.

In a bathroom with a fixed partition of 90 or 100 cm, 8mm is often the most balanced solution. It feels good, doesn't look "light" and can be properly supported with a proper profile and bracket. It is the choice often found in well-designed home bathrooms.

On a large frameless panel, especially if we want a very clean minimal image, 10mm may be more suitable. But there you have to pay attention to the wall, the supports and the weight. The thicker glass does not forgive rough placement.

In a rental where the owner is considering acrylic paneling for economy, a simple framed cabin with real safety glass may be the best decision. The initial cost may be a little more, but the image, durability and cleanliness will be better.

Do not buy a shower enclosure based only on glass thickness. An 8 mm panel with proper support is often a better choice than 10 mm glass paired with weak fittings.

For standard framed enclosures, 6 mm may be enough. For fixed panels and cleaner frameless solutions, 8 mm is usually the best balance. Ten millimeters makes more sense on larger or more premium dividers, but it requires serious support.

Avoid acrylic "glass" if you want a quality, long-term solution. It may cost less, but it scratches, goes cloudy, and never feels the same as real safety glass.

In a shower enclosure, safety comes before aesthetics. Ask for safety glass, properly finished edges, and professional installation.

The glass of the shower cabin is not just glass. It is an element of safety, ergonomics and aesthetics. That is why it must be chosen based on the type of glass, thickness, support, dimensions and use.

6mm is often sufficient in full frame cabs with standard dimensions. 8mm is the most balanced choice for many fixed panels and quality cabs. 10mm gives a premium feel and more robustness in large frameless applications, but requires proper components and strong support.

The word “securit” should not be used lightly. The owner must ask for clear confirmation that the glass is safety and suitable for a shower cubicle. Edges, holes, supports and placement are just as important as thickness.

Acrylic "glass" may seem economical, but it usually loses in clarity, strength, feel and durability. For a bathroom that we want to look quality and function properly for years, real safety glass is the right choice.
