Why Sintered Stone is the Smartest Splashback for Your Kitchen
Most kitchen splashback decisions come down to two questions: will it look good, and will it hold up? Sintered stone answers both with technical specifications that glass, tile, and most natural stone cannot match — and one installation advantage behind gas cooktops that most renovators don't find out about until they're already mid-project.

The Gas Cooktop Clearance Advantage
Australian standard AS/NZS 5601.1 requires combustible materials installed behind a gas cooktop to maintain a minimum clearance distance from the appliance. Sintered stone is classified as non-combustible, which means it is not subject to those clearance restrictions. You can install it directly behind a gas cooktop without the gap that some materials require by code.
For anyone designing a kitchen with a gas cooktop and wanting a continuous slab behind the cooking zone — no break, no transition material, no grout line interrupting the surface — sintered stone is one of very few materials that makes this possible without a compliance workaround.
If you are using induction or electric, the benefit is purely aesthetic: a full-height, joint-free splashback from benchtop to rangehood in a single continuous surface.
No Sealing, No Grout, No Maintenance Schedule
A tiled splashback is a maintenance commitment. Grout lines absorb oil, attract mould, and discolour over years of cooking. Glass splashbacks look sharp on day one but show fingerprints, water marks, and scratches from daily use. Natural stone needs periodic sealing and is vulnerable to the acidic environment behind a cooktop — tomato, lemon, vinegar, wine.
Sintered stone has a water absorption rate below 0.05%, which makes it functionally impermeable. Nothing penetrates the surface. Chemical Resistance Class A means household cleaning products, food acids, and cooking residues wipe clean without affecting the material. At Mohs 7 on the hardness scale — harder than marble, harder than granite — it will not scratch under normal kitchen use.
There is no sealing schedule. No grout to maintain. The surface you install is the surface you have in ten years.
Thickness, Slab Size, and What That Means in Practice
For splashback applications, sintered stone is typically installed at 6mm or 12mm thickness. The 6mm format suits wall cladding and splashbacks where weight is a consideration, and it cuts cleanly for mitred joints and around-window returns that kitchen renovations often require.
Slabs are available up to 320cm in length. For most kitchen runs, this means the entire splashback can be covered in a single slab — no vertical join behind the cooktop, no break across the window return. In open-plan kitchens where the splashback is a visible architectural element rather than a background detail, this matters.
Fabrication should be carried out by a trained sintered stone fabricator. Asetica has conducted over 100 fabricator tests across Australia and maintains a network of vetted fabricators in New South Wales, Western Australia, and Victoria. If you need a referral, contact the showroom directly.
Choosing the Right Colour for Your Kitchen
The splashback connects the benchtop to the overhead cabinetry, so material consistency matters as much as colour. Four surfaces perform particularly well in kitchen splashback applications.
Taj Mahal
A warm white with soft gold veining that reads as natural quartzite without the maintenance of natural stone. It works across white, timber, and dark cabinet palettes and lends itself to benchtop-and-splashback matching where a single continuous material is the brief.
Taj Mahal Royale
Carries bolder, more pronounced veining than the standard Taj Mahal. Better suited to kitchens where the splashback is a feature rather than a background — particularly effective behind a statement rangehood or in a kitchen with minimal upper cabinetry.
Loro White
A cooler, cleaner white with a subtle surface texture. Where the brief calls for a contemporary, understated result — especially in kitchens with matte black or brushed brass hardware — Loro White reads as precise without being clinical.
Wild Ferrara WA Exclusive
Available exclusively through Asetica's Perth showroom. It carries a warm grey movement with irregular veining that suits Australian residential projects where natural variation is part of the design intent. Perth-based renovators should view this in person — slab variation is significant enough that a sample alone will not give the full picture.

How the Engineered Stone Ban Changed the Splashback Conversation
Since the July 2024 engineered stone ban, specifiers and homeowners have been reconsidering what goes into Australian kitchens. The ban applies to engineered stone benchtops in workplaces under WHS legislation, but it has accelerated a broader reassessment of material choices across the kitchen. Sintered stone is not subject to the ban and carries no workplace health restrictions under current Australian law.
Sintered stone and engineered stone are different materials produced by different processes. Sintered stone is manufactured by compressing and firing natural mineral compounds at temperatures exceeding 1,200 degrees Celsius, producing a surface that is non-combustible, fully vitrified, and compliant with Australian standards — certifications engineered stone never held. For anyone who was planning an engineered stone kitchen and is now reconsidering their material choice, sintered stone offers comparable aesthetics at equivalent or better technical performance. More detail is available in our complete guide to the engineered stone ban.
Splashback Material Comparison
| Material | Heat Resistance | Gas Cooktop Clearance | Sealing Required | Grout Lines |

| Glass | ★★★☆☆ | Clearance required | Never | None |
| Natural Stone | ★★★★☆ | Clearance required | Annual | None (full slab) |
| Ceramic Tile | ★★★☆☆ | Clearance required | Grout only | Yes |
| Engineered Stone | ★★☆☆☆ | Clearance required | Never | None |
Frequently Asked Questions: Sintered Stone Splashbacks
Does sintered stone need clearance behind a gas cooktop?
No. Sintered stone is classified as non-combustible under Australian standards, so the minimum clearance requirements that apply to combustible materials under AS/NZS 5601.1 do not apply. You can install it directly behind a gas cooktop.
Can sintered stone be used behind induction or electric cooktops?
Yes, without any restrictions. The non-combustibility advantage is most relevant to gas cooktop installations. For induction and electric, sintered stone is simply the cleanest, most maintenance-free option available — the full-slab format and zero-maintenance surface make it the logical choice regardless of cooktop type.
Does sintered stone need sealing as a splashback?
No. Water absorption below 0.05% means the material is functionally impermeable — there is nothing for a sealer to protect against. This also means cooking residues, food acids, and cleaning products cannot penetrate the surface. Wipe clean with water and mild soap.
What thickness is right for a kitchen splashback?
12mm is the standard for splashback applications. It reduces wall load, cuts cleanly for returns and cutouts around power points, and produces a refined edge profile. Using 20mm is perfectly fine also, as long as the cabinetry has supported a bigger thickness. However the 12mm offers easy installation, plus a more affordable price point.
Can I match my benchtop and splashback in the same sintered stone?
Yes, and this is one of the most popular applications. Because slabs are available up to 320cm in length, a continuous benchtop-to-splashback run in the same material is achievable for most kitchen configurations without a join. Taj Mahal is the most commonly specified colour for this approach.
How do I find a fabricator for sintered stone?
Asetica maintains a network of vetted fabricators across New South Wales, Western Australia, and Victoria. Contact either showroom directly for a referral. Sintered stone requires specific tooling and technique — using a fabricator without sintered stone experience increases the risk of edge chipping and incorrect joint finishing.
To see the full splashback range in person, visit the Sydney showroom in Padstow or the Perth showroom in Subiaco, both open seven days. Complimentary samples are posted directly to your address if you want to test colours against your cabinetry before committing.
