Splashbacks: Glass, Tile & Stone Options

A kitchen splashback sits between your worktop and wall cabinets, protecting the wall surface from water, grease, and heat. The choice of material affects how much maintenance the area needs, how it copes near a hob, and how easy it is to keep clean. Costs vary enormously, from around £15/m² for standard ceramic tiles to over £400/m² for premium sintered stone panels, so it pays to understand what you are buying before committing.

This guide covers the six main splashback material categories used in UK kitchens in 2026, with realistic supply costs, practical installation notes, and the Building Regulations requirements that apply near gas and electric hobs.

Building Regulations: What You Must Know Near a Hob

Before choosing a material, check whether your hob is gas-fired, and check where the clearance rule actually comes from, because it is not where it is usually said to be. Approved Document J governs combustion appliances, and what it deals with is flues, air supply for combustion, and hearths; it sets no 150 mm non-combustible zone around a gas burner. The clearances that matter for a hob come from BS 6172, the installation code for domestic gas cooking appliances, and from the appliance manufacturer’s own installation instructions, which a Gas Safe installer has to follow. In practice that rules out acrylic and most plastic sheet immediately behind a gas hob; the distances are the manufacturer’s, so read them off the instructions for the hob you are buying rather than from a rule of thumb.¹

For electric hobs, Approved Document J does not apply at all, but Approved Document B still governs how wall linings perform in a fire. Ignore any datasheet still quoting Class 0: it was a national classification and appears nowhere in the current Approved Document B. The system now is the Euroclasses, and for a wall lining in a room the provision is C-s3,d2 or better, tightening to B-s3,d2 in a circulation space. Toughened glass, ceramic tile, natural stone, stainless steel and sintered stone all clear that comfortably; acrylic does not.²

Splashback Heights and Dimensions

Standard practice is to run a splashback 450–600 mm high behind the hob, rising from the worktop surface to the underside of the wall cabinet. The minimum recognised height above a worktop is 150 mm, although many designers and kitchen fitters recommend taking it to the full cabinet height for a cleaner result and better protection.

If you have no wall cabinet above the hob, the splashback typically runs to the height of adjacent cabinets (usually 700–750 mm above the worktop) or as a full height panel to the ceiling.

Glass Splashbacks

Toughened glass panels are one of the most popular choices for modern UK kitchens. The glass must be a minimum of 6 mm toughened safety glass, compliant with BS EN 12150, which requires it to fragment into small, relatively harmless pieces rather than large sharp shards if broken.

Glass is supplied in almost any RAL or BS colour (including back-painted opaque glass) and can be cut to precise dimensions, making it well-suited to awkward alcoves or unusual layouts. There are no grout lines, so the surface wipes clean in seconds.

Key facts:

• Typical supply cost: £100–£300/m² (custom colour, cut to size)
• Installation: glass specialist required; fitting typically costs £100–£250 per panel depending on size and number of cut-outs for sockets
• Standard thickness: 6 mm (some premium suppliers offer 8 mm for larger spans)
• Heat resistance: suitable directly behind induction and electric hobs; check with the manufacturer for proximity to gas flame
• Jointing: silicone bead between panel and worktop, usually no visible fixings

The main drawback is cost, a standard 3 m run behind a hob and surrounding worktop area can easily reach £600–£900 supplied and fitted. Chips are difficult to repair invisibly, though panels can be replaced individually.

Ceramic and Porcelain Tiles

Tiles remain the most widely used splashback material in UK kitchens. They are available in an almost unlimited range of sizes, finishes, and formats, from 75 × 150 mm metro tiles to large-format 600 × 1200 mm porcelain slabs, and the individual tile cost is low enough that most budgets can accommodate them.

Ceramic tiles are the cheaper option and perform well in low-heat zones, but porcelain is denser, more durable, and handles heat better. Large-format porcelain in a rectified finish (precision-cut edges) can create a near-seamless look with very fine grout joints.

Key facts:

• Ceramic tiles: £15–£40/m² supply
• Porcelain tiles (standard format): £25–£80/m² supply
• Large-format porcelain slabs: £60–£150/m² supply
• Installation: tiler at £25–£45/m² labour (simple layouts; pattern or mosaic work costs more)
• Grout: standard cement grout stains over time near cooking zones; epoxy grout (£30–£50 per kg, covers roughly 3–5 m² at a 3 mm joint) is significantly more hygienic, stain-resistant, and worth the extra cost in a kitchen

The main maintenance issue is grout. Even epoxy grout requires occasional cleaning in the joint, and standard cement grout near a hob will discolour within a few months. Tiles can also crack if a heavy pan strikes them directly, particularly at the edge nearest the hob.

Natural Stone (Marble, Granite, Slate)

Natural stone gives a high-end result and is genuinely heat-resistant, but it is porous and requires ongoing maintenance. Marble in particular is susceptible to acidic substances, tomato, lemon juice, vinegar, which etch the polished surface.

All natural stone used as a splashback should be sealed on installation and resealed annually (or more frequently with heavy use). A penetrating impregnator sealer is standard; some stones require two or three coats initially.

Key facts:

• Marble: £100–£250/m² supply (varies widely by origin and veining pattern)
• Granite: £80–£180/m² supply
• Slate: £40–£100/m² supply
• Installation: stone specialist or experienced tiler; natural stone is heavy and requires appropriate adhesive (rapid-set polymer-modified)
• Sealing: adds cost and ongoing maintenance compared to non-porous alternatives

Marble and granite can crack if subjected to sudden temperature changes, though this is rare in normal domestic use. Ensure stone panels are not placed directly in front of a gas burner without a heat buffer.

Stainless Steel Sheet

Stainless steel is the material of choice in commercial kitchens and has crossed into domestic use, particularly in industrial-style or contemporary kitchen schemes. It is non-combustible, immune to water, heat-resistant to very high temperatures, and does not require sealing.

The trade-off is appearance over time: stainless steel shows fingerprints, scratches, and water marks persistently. Brushed finishes are more forgiving than mirror-polished ones, but both require regular wiping with a microfibre cloth. Once scratched, a brushed-finish panel can be re-grained with a specialist pad; a polished panel cannot easily be restored.

Key facts:

• Supply cost: £80–£200/m² (1.2 mm–1.5 mm gauge sheet, cut to size)
• Fixing: adhesive-mounted or mechanically fixed with cover strips at edges
• No special installation trade required, careful measurement and panel alignment is the main skill
• Grade: 304 stainless steel is standard for domestic kitchens; 316 for coastal environments where salt air is an issue

Acrylic and Plastic Panels

Acrylic splashback panels are the cheapest option and are sold widely in DIY sheds and online. They are lightweight, easy to cut, and quick to install, many homeowners fit them as a straightforward DIY project.

The critical limitation is heat resistance. Acrylic softens at temperatures above approximately 80–90 °C and is not suitable close to a gas burner; the clearance to observe is the one in the hob manufacturer’s installation instructions and in BS 6172, not a figure from Part J. Even near an electric hob, positioning matters, panels should not be placed in a location where direct radiated heat from the hob surface or pots could cause warping.

Key facts:

• Supply cost: £20–£60/m²
• Thickness: typically 3 mm or 4 mm
• DIY-friendly: scores and snaps, or cuts with a fine-toothed saw
• Not suitable near gas hobs; use with caution near electric hobs
• Lifespan: 5–10 years before yellowing or surface crazing becomes visible; lower than all alternatives

Acrylic is a reasonable choice for bathroom splashbacks where heat is not a consideration, or for the section of wall away from the hob in a kitchen. It is not a long-term kitchen-hob solution.

Sintered Stone (Dekton and Equivalents)

Sintered stone panels, manufactured from a blend of glass, porcelain, and quartz minerals under extreme pressure and heat, represent the premium end of the splashback market. The resulting material is exceptionally dense, non-porous, UV stable, and highly resistant to heat. Large-format slabs (up to 3200 × 1440 mm from major manufacturers) allow a near-seamless installation across a full kitchen run.

Unlike natural stone, sintered stone does not require sealing and resists virtually all household chemicals. Thermal shock resistance is significantly better than glass or natural stone. It can be used directly adjacent to gas burners without concern.

Key facts:

• Supply cost: £200–£500/m² depending on thickness and format
• Standard thickness: 6 mm, 12 mm, or 20 mm slabs (6 mm for splashbacks)
• Installation: specialist fabricator required; cutting requires diamond tooling; fixing with specialist adhesive
• Not DIY-friendly; errors in measurement or cutting are costly
• Lifespan: 25+ years with normal use

How to Choose

Budget-conscious and willing to maintain grout: porcelain tiles with epoxy grout are the most cost-effective long-term option. They survive heat well and are easy to replace if damaged.

Wanting a seamless, easy-clean surface: glass is the most accessible seamless option. Sintered stone is the premium version with better heat and durability credentials.

Gas hob in the property: eliminate acrylic from consideration for the zone around the burner, to the clearance the hob manufacturer specifies and BS 6172 requires. Glass, tile, stone, steel, and sintered stone all comply.

Rental property or short-term budget: acrylic panels away from the hob, or basic ceramic tiles, offer a quick, cost-effective result that still protects the wall.

High-use, heavy cooking kitchen: stainless steel or sintered stone will outlast everything else without any maintenance beyond wiping down.

For most domestic UK kitchens, the practical choice sits between mid-range porcelain tiles with epoxy grout (£40–£120/m² fully installed) and a toughened glass panel (£200–£500 per panel fitted). Both are durable, heat-safe, and straightforward for an experienced kitchen fitter to install to a professional finish.
