How Far Up the Wall Should a Splashback Go?

One of the most common questions homeowners ask when planning a kitchen or bathroom is how high a splashback should extend. The answer depends on function, layout, and how the space is used—but there are well-established guidelines that work in most situations.

Standard Splashback Height

Traditionally, splashbacks extend from the top of the worktop to the underside of the wall cabinets. This typically measures 500–600mm, depending on the kitchen design.

This height provides sufficient protection from everyday splashes while maintaining a clean, balanced look. It remains the most commonly specified option in both traditional and modern kitchens.

Full-Height Splashbacks

In some designs, splashbacks run from the worktop all the way to the ceiling. This approach is often chosen behind cooktops or in kitchens without wall cabinets.

Full-height splashbacks:

• Offer maximum wall protection

• Create a strong visual feature

• Reduce the need for additional finishes

Glass splashbacks are particularly effective in full-height applications due to their seamless appearance.

Splashback Height Behind a Cooktop

Behind a hob or cooktop, splashback height is more than a design choice—it’s a performance requirement. Many homeowners choose to extend the splashback higher in this area to manage heat and grease.

Made-to-measure options from DIY Splashbacks allow you to increase height exactly where it’s needed without over-installing elsewhere.

Bathroom Splashback Height

In bathrooms, splashbacks behind basins usually extend 300–400mm above the sink or up to the bottom of a mirror or cabinet. This provides effective protection while keeping the space visually light.

In high-use or commercial-style bathrooms, full-height splashbacks are also a practical choice.

Is There a Minimum or Maximum Height?

There is no strict legal minimum, but best practice is to cover any area exposed to regular water, heat, or cleaning. The maximum height is largely a design decision, as long as materials are suitable for the environment.

From a traditional standpoint, splashbacks should always be tall enough to prevent damage. Modern materials simply give you more flexibility in how that’s achieved.

In Summary

The ideal splashback height depends on how and where it’s used. Standard heights work well for most kitchens, while full-height options offer added protection and visual impact in key areas.

By choosing the right height—and specifying it accurately—you ensure your splashback performs properly and complements the overall design of your space.

What Areas Actually Need a Splashback?

Not every wall in a kitchen or bathroom requires protection, but certain zones are exposed to constant heat, moisture, and splashes. Identifying where a splashback is truly necessary helps you plan efficiently and avoid over- or under-specifying your space.

Behind the Cooktop or Hob

This is the most critical location for a splashback. Cooking generates heat, oil splatter, and steam, all of which can damage unprotected walls over time.

A splashback installed behind the cooktop:

• Protects walls from grease buildup

• Resists heat exposure

• Simplifies cleaning after cooking

Traditionally tiled, this area now benefits from glass splashbacks that offer seamless coverage and modern performance.

Behind the Sink

Water splashes are unavoidable when washing dishes or hands. Without a splashback, moisture seeps into paint and plaster, leading to staining and peeling.

A splashback behind the sink creates a waterproof barrier that preserves the wall surface and maintains a clean, professional finish.

Along the Main Worktop

Any wall directly above a work surface is exposed to spills, food preparation mess, and frequent cleaning. Installing a continuous splashback along the worktop ensures consistent protection and visual continuity.

Made-to-measure splashbacks from DIY Splashbacks allow you to extend coverage precisely where it’s needed—no more, no less.

Bathroom Vanities and Basins

Bathrooms are high-moisture environments. Walls behind basins and vanities benefit significantly from splashbacks, which prevent water damage and support hygiene.

Glass splashbacks are particularly effective here, as they resist humidity and are easy to clean.

Utility Rooms and Laundry Areas

Splashbacks are not limited to kitchens and bathrooms. Utility rooms, laundry areas, and even wet rooms can benefit from splashback protection behind sinks and appliances.

These functional spaces demand durability over decoration—making splashbacks a practical, traditional solution.

Areas That Don’t Always Need a Splashback

Walls away from water, heat, or food preparation generally do not require splashback protection. Installing splashbacks only in high-impact zones ensures efficient use of materials while maintaining a clean design.

Final Takeaway

You need a splashback wherever heat, water, or frequent cleaning occurs. Focusing on these key zones ensures your space remains protected, hygienic, and visually cohesive.

From a traditional planning standpoint, this is about protecting surfaces where damage is most likely. From a modern perspective, it’s about doing so with better materials and smarter design.

Why Do I Need a Splashback?

When planning or upgrading a kitchen or bathroom, it’s easy to focus on cabinets, worktops, or fixtures. However, one element that consistently proves its value—both functionally and visually—is the splashback. Far from being an optional extra, a splashback plays a critical role in protecting your space and maintaining its long-term appeal.

Protecting Your Walls from Everyday Wear

Kitchens and bathrooms are high-impact environments. Heat from cooking, water splashes from sinks, and airborne grease all place constant pressure on wall surfaces. Traditionally, tiled walls were used to manage this exposure, and the reasoning behind that choice remains valid today.

A splashback acts as a dedicated protective barrier, shielding your walls from stains, moisture damage, and heat exposure. Without it, painted or plastered walls can quickly show signs of wear, leading to peeling paint, discoloration, and costly repairs.

A Smarter Long-Term Investment

Installing a splashback is a proactive decision that reduces maintenance and future expenses. Rather than repeatedly repainting or repairing damaged walls, a single, well-installed splashback preserves the underlying structure of your space.

From a value perspective, this is about protecting your investment. A kitchen or bathroom that remains clean, intact, and visually cohesive retains its appeal and usability for years to come.

Modern splashbacks, particularly glass splashbacks, offer smooth, non-porous surfaces that are easy to clean. Unlike traditional tiles with grout lines, they do not trap dirt, grease, or bacteria.

This makes everyday cleaning quicker and more effective, aligning with both traditional standards of cleanliness and modern expectations for low-maintenance living.                                                       

Performance in High-Use Areas

Certain zones demand extra resilience—especially behind cooktops, hobs, and sinks. A properly specified splashback is designed to withstand heat, moisture, and frequent cleaning without deteriorating.

Made-to-measure solutions from DIY Splashbacks ensure the splashback fits precisely within your space, delivering reliable performance while maintaining a clean, professional finish.

Enhancing the Overall Look of Your Space

Beyond functionality, a splashback brings visual structure to a room. It creates a clear transition between work surfaces and walls, giving the space a finished, intentional appearance.

With options ranging from subtle neutrals to bold colors, modern splashbacks allow you to respect classic kitchen and bathroom layouts while introducing a refined, contemporary edge.

Is a Splashback Really Necessary?

While it may not always be a legal requirement, a splashback is widely considered best practice—especially in high-use areas. It protects vulnerable surfaces, simplifies maintenance, and elevates the overall quality of the room.

Skipping a splashback often leads to avoidable damage and unnecessary upkeep, making it a false economy rather than a cost-saving measure.

Final Thoughts

You need a splashback because it protects your walls, supports hygiene, reduces maintenance, and completes the design of your kitchen or bathroom. It’s a practical solution rooted in traditional building principles, enhanced by modern materials and manufacturing.

In short, a splashback doesn’t just improve how a space looks—it ensures it performs properly for the long term.

Short answer: YES ,but only at the right stage of production.           

When a Glass Splashback Can Be Cut

Glass splashbacks are cut to size before toughening, not after.

During manufacturing, the glass is:

1. Measured and cut to exact dimensions

2. Shaped for sockets, switches, or cut-outs

3. Edge-polished for safety and finish

4. Then toughened to increase strength and heat resistance

Once this toughening process is complete, the glass becomes extremely strong—but also impossible to modify. Any attempt to cut or drill it afterward will cause it to shatter.

This is why made-to-measure suppliers like DIY Splashbacks emphasize accuracy at the ordering stage.

Why Glass Can’t Be Cut After Toughening

Toughened glass is designed to be under internal tension. This is what gives it its durability and safety performance. However, that same tension means:

• It cannot be resized

• Holes cannot be added later

• Edges cannot be trimmed

This isn’t a limitation—it’s a safety feature that’s been standard in the glass industry for decades.

What This Means for Customers Measuring at Home

For customers measuring themselves, precision is critical. Even small errors can lead to:

• Poor fit

• Installation stress

• The need to reorder panels

That’s why suppliers such as DIY Splashbacks provide clear measuring guidance and recommend double-checking all dimensions before placing an order.

Can Installers Cut a Splashback On-Site?

No. Installers do not cut toughened glass on-site. Any splashback that requires trimming after delivery will need to be remade.

This is also why glass splashbacks differ from tiled alternatives. Tiles allow for adjustment during installation; glass relies on upfront accuracy instead.

Why Custom Cut Splashbacks Are Still the Best Option

Although the process demands precision, custom-cut glass splashbacks deliver:

• Seamless, grout-free finishes

• Perfect alignment with sockets and appliances

• Faster, cleaner installation

• Long-term durability

From a value and performance standpoint, custom sizing has become the modern extension of traditional craftsmanship.

Final Takeaway

Yes, a glass splashback can be cut to size—but only before it is toughened.
Once manufactured, the dimensions are fixed, making accurate measurements essential.

By working with experienced suppliers like DIY Splashbacks, customers ensure their splashbacks are produced correctly the first time—saving time, cost, and unnecessary stress.

Does Splashback Thickness Affect Heat Resistance?

In principle, yes—but in practice, not in the way most people assume.

When choosing a glass splashback, thickness often gets mistaken for heat performance. In reality, heat resistance is driven by glass toughening and correct installation, not by simply making the glass thicker. This distinction is critical and is grounded in long-established industry practice.

The Role of Toughened Glass

Glass splashbacks are manufactured using toughened (tempered) glass, a process that dramatically increases heat resistance and impact strength. Once glass is properly toughened, it can tolerate high temperatures and sudden temperature changes common behind cooktops.

This is why a 6mm toughened glass splashback has become the industry standard. It consistently delivers reliable thermal performance without introducing unnecessary weight or complexity.

Why Thicker Doesn’t Mean More Heat Resistant

It’s a common misconception that thicker glass automatically handles heat better. In reality:

• Thicker glass does not significantly increase heat tolerance

• It adds weight, which affects wall loading and installation

• It increases cost without improving safety in standard kitchen setups

From a traditional, best-practice standpoint, increasing thickness beyond 6mm provides diminishing returns for heat management.

Installation Matters More Than Thickness

Heat issues almost always stem from poor installation, not insufficient glass thickness. Proper clearances between the splashback and heat sources—especially gas hobs—are essential.

Suppliers like DIY Splashbacks engineer splashbacks as a complete system, factoring in thickness, toughening, cut-outs, and recommended spacing to manage heat safely and consistently.

The Proven Standard: 6mm Toughened Glass

Decades of use have validated 6mm toughened glass as the optimal choice for kitchen splashbacks. It offers:

• Reliable heat resistance

• Safer handling and installation

• Predictable performance over time

• Consistent color and finish

This is why it remains the preferred specification across residential projects and professional installations.

Final Takeaway

Splashback thickness alone does not determine heat resistance.
What matters is using properly toughened glass at the correct thickness—most commonly 6mm—installed with appropriate clearances.

It’s a solution rooted in experience, refined by modern manufacturing, and still the most dependable choice today.

Why Splashback Thickness Matters

Traditionally, wall protection near heat and water has always favored materials that balance strength with practicality. Glass splashbacks follow the same rulebook.

Thickness impacts:

• Heat resistance behind cooktops

• Structural stability during installation

• Edge finishing and cut-out precision

• Cost control and lead times

Get this wrong, and you introduce unnecessary risk into an otherwise straightforward upgrade.

The Industry Standard: 6mm Glass Splashbacks

6mm toughened glass is the market benchmark—and for good reason.

From an operational standpoint, it delivers:

• Proven heat resistance (when correctly installed)

• Safe handling and installation

• Clean edge polishing

• Consistent visual clarity and color accuracy

Suppliers like DIY Splashbacks default to 6mm because it aligns with decades of manufacturing data and installation outcomes. It’s the thickness that works—repeatedly.                                                                                   

When Would You Use Thicker Glass (8mm or 10mm)?

Thicker splashbacks exist, but they’re context-specific, not the norm.

Consider thicker glass if:

• The splashback is oversized or freestanding

• It’s used as a feature panel, not just wall protection

• The design brief prioritizes visual weight over efficiency

That said, thicker glass increases:

• Cost

• Installation complexity

• Weight load on walls

From a traditional value perspective, thicker isn’t automatically better—it’s just heavier.

Is Thinner Than 6mm Ever Acceptable?

In short: no for kitchens.

Anything below 6mm introduces unnecessary fragility and compromises safety near heat sources. Historically, cutting corners on material thickness always costs more long term. Modern standards simply formalize that lesson.

Thickness and Heat: What You Need to Know

Glass splashbacks must be toughened regardless of thickness. However, 6mm toughened glass has the best track record when paired with proper clearances from gas or electric hobs.

Reputable suppliers—such as DIY Splashbacks—design thickness, cut-outs, and heat zones as a single system, not isolated decisions. That’s where risk mitigation happens.

Does Thickness Affect Color and Finish?

Yes—but subtly.

• Thicker glass can deepen color tones

• 6mm glass delivers the most predictable color outcome

• Digital printing and painted finishes are optimized for 6mm panels

From a brand and consistency standpoint, 6mm ensures what you see in samples is what you get on the wall.

Final Takeaway: Stick With What Works

If you’re making a decision based on:

• Performance

• Safety

• Cost efficiency

• Proven results

Then 6mm toughened glass remains the correct call for most residential splashbacks.

It’s the thickness the industry was built on—and the one modern suppliers like DIY Splashbacks continue to stand behind because it delivers predictable outcomes at scale.

Are Glass Splashbacks Safe Behind Cooktops?

Glass splashbacks are a popular choice for modern kitchens, combining aesthetic appeal with practical functionality. But one of the most common questions is about their safety when installed behind cooktops. Let’s break it down.

The Role of Toughened Glass

Safety begins with the right material. Glass splashbacks designed for use behind cooktops are made from toughened (tempered) glass. This type of glass undergoes a controlled heat treatment that makes it significantly stronger than standard glass. It’s designed to withstand high temperatures and impact.

Heat Resistance and Thermal Shock

One of the key safety features of toughened glass is its ability to resist thermal shock. This means that the glass can handle the heat generated by cooktops without warping or cracking. This is crucial for maintaining both safety and structural integrity.

Controlled Breakage Patterns

In the unlikely event that toughened glass does break, it shatters into small, blunt fragments rather than sharp shards. This significantly reduces the risk of injury, making it a safe option for kitchen environments.

Installation Best Practices

Proper installation is critical. Ensuring that the glass is measured and fitted accurately, with the correct clearances from heat sources, is essential for safety. Using quality fixings and following manufacturer guidelines ensures that the splashback remains secure and safe over time.

Professional Installation

Proper installation is key to ensuring safety. Accurate measurements, correct clearances, and quality fixings are essential. DIY Splashbacks ensures that each panel is custom-cut and fitted to meet safety standards.

In a market saturated with fleeting trends and short-term design statements, splashbacks remain a strategic constant. They are not a novelty. They are infrastructure. For decades, splashbacks have delivered on one core promise: protect high-use surfaces while elevating the visual integrity of a space. That mandate has not changed—only the execution has evolved.

A Legacy Built on Function First

Historically, splashbacks were installed for one reason: practicality. Kitchens and bathrooms demanded a surface that could withstand heat, moisture, stains, and daily wear without degradation. Glass, tile, and stone became the default not because they were fashionable, but because they performed consistently over time.

That foundational logic still governs smart design decisions today. While finishes and color palettes rotate, the requirement for durability, hygiene, and ease of maintenance remains non-negotiable.

Modern Homes, Same Expectations—Higher Standards

Today’s homeowners expect more. Spaces are open-plan, multifunctional, and visually scrutinized. Splashbacks now operate at the intersection of performance and brand identity within the home. They frame cooking zones, define bathrooms, and increasingly act as subtle focal points rather than background elements.

Modern glass splashbacks, in particular, demonstrate how legacy concepts can be optimized for contemporary living. Clean lines, customizable color options, and seamless installation allow homeowners to preserve traditional reliability while upgrading aesthetic value. Suppliers such as DIY Splashbacks exemplify this evolution by offering made-to-measure solutions that respect established building principles while embracing modern manufacturing precision.

Durability as a Long-Term Asset
