Tempered Glass Kitchen Backsplash: Behind the Hob, Sink and Shelves
A glass splashback turns the wall behind your worktop into one smooth, wipe-clean surface. This guide, part of our tempered glass series, covers where it works, what "heat resistant" really means, and how to prepare the details before the glass is made.
Quick answer
Short answer: yes, tempered glass is a sensible backsplash material, including behind a hob, as long as you follow the hob maker's clearance instructions and settle every cut-out before tempering. It is tougher against heat changes than ordinary glass, but it is not fireproof and it cannot be altered once made.
Why people choose a tempered glass backsplash
Tiles are the default behind a kitchen worktop, and they work, but every grout line is a place for grease and steam to settle. A single sheet of glass has no grout. One pass with a cloth takes off splashes, and the wall behind stays protected from moisture and cooking oil.
Glass also changes how a small kitchen feels. A clear or light-coloured surface bounces light around the room, and a coloured one gives you a clean block of colour without paint that can peel. People searching for a "tempered glass backsplash for kitchen" are usually after exactly this: a surface that looks tidy and is quick to maintain. The rest of this page is about doing it properly so that it stays that way.
"Heat resistant" is not the same as fireproof
You will see the phrases "toughened glass heat resistant splashback" and "tempered glass heat resistant" used loosely online. The honest picture is more careful. Tempering heats the glass and cools it rapidly, which leaves the surface under compression. That makes it far better than ordinary glass at coping with knocks and with moderate changes in temperature across the sheet.
It does not make the glass immune to fire or to every kind of heat. A flame licking the edge, a very hot pan pushed hard against the wall, or cold water thrown on a surface that has been heated for a long time can still stress it. Think of tempered glass as a tougher material with limits, not as a heat shield.
| Common belief | What is closer to the truth |
|---|---|
| Tempered glass cannot crack from heat | It copes with heat changes much better than ordinary glass, but uneven or concentrated heating can still break it |
| Heat resistant means fireproof | No. It is not a fire barrier and should not be used as one |
| I can ask the glass shop to make it extra heat proof | Tempering is a fixed process; what you control is the position, the clearance and the support around it |
| If it is tempered I can trim it on site | Never. Cutting, drilling and edge work all happen before tempering |
| Back-painted glass is weaker | Paint does not make it a different glass type; the glass underneath is the same tempered sheet |
Where tempered glass works in a kitchen
The most common spot is the full wall between the worktop and the wall cabinets, running behind the sink and the hob. Beyond that, the same material suits several other places.
Behind the hob: the busiest and most demanding position, covered in the next section.
Behind and beside the sink: splashes of water and soap are easy to wipe, and the wall stays dry.
Open shelves and glass shelves: a glass shelf inside a kitchen unit is covered on our page about tempered glass table tops and shelves.
Cabinet door inserts: glass panels in doors for display units. If you want full glass doors, see our glass doors page.
Island ends and bar backs: a decorative panel facing the room, usually away from direct heat.
Under-cabinet strips: a narrow band of glass on a short wall run, such as a coffee corner.
Where the glass sits near heat, follow the rules below. Where it is purely decorative, the planning is lighter, but cut-outs and edges still need to be fixed before it is made.
Behind the hob: follow the maker's clearance
This is where most questions come from, such as "tempered glass backsplash for kitchen behind stove". The reliable rule is simple: your hob or cooker comes with installation instructions that state the minimum clearance to the wall and to any surface behind it. Those instructions come from the people who built the appliance and they take priority over anything a glass page says, including this one.
Before you order, find those instructions, or the appliance model, and share them with us. Gas and electric or induction hobs behave differently, and a cooker with a high back guard differs again. We can then plan the glass around the appliance rather than guess. If the instructions require a gap between the hob and the glass, leave that gap even if it looks tidy to fill it.
A habit worth keeping
Keep pans centred on the burners and avoid pushing hot cookware against the glass. Most heat problems with splashbacks come from flames or hot metal sitting right against the surface, not from normal cooking.
Clear, back-painted and decorative options
A backsplash is usually seen from the front, so the finish is applied to the back of the glass, where it is protected from steam and cleaning. The choice affects how the wall behind looks and how forgiving the surface is.
Which finishes we can supply changes from time to time, so confirm what is available when you contact us rather than assuming. For a wider look at tints and surface treatments, read our finishes and tints guide.
| Option | How it looks | Worth knowing |
|---|---|---|
| Clear glass | Shows the wall or tile behind it | Wall must be tidy and finished; any marks show through |
| Back-painted solid colour | Even block of colour, often glossy | Good for hiding an uneven wall; test the colour against your worktop |
| Light or neutral back colour | Soft, bright, easy to match | Splashes of oil may be easier to spot, so keep a cloth handy |
| Tinted or frosted | Muted, partly hidden view | Ask what is available and view a sample in your own light |
| Mirror-style back | Reflective | See our custom mirrors page; mirror is a separate product |
Ask to see a sample piece, and look at it by the window where your kitchen light comes from. A colour that looks right in a showroom can read quite differently under your own kitchen lighting.
Sockets, switches and cut-outs: decide before tempering
This is the single most important practical rule. Tempered glass cannot be drilled, notched or cut after tempering. A hole for a socket, switch or tap must be made in the glass before it is toughened, and its position must be exact.
So treat the electrical points as part of the measuring job, not an afterthought. A cut-out placed even slightly wrong cannot be corrected on site; the glass would have to be remade.
Mark every socket, switch, cooker hood connection and tap position on the wall with a pencil.
Measure from a fixed edge, such as the worktop or a side wall, to the centre of each point, and also note the size of the plate.
Decide whether the plate sits on top of the glass or the glass has an opening around it. This changes the cut-out size.
If a new socket is planned, have your electrician fix its position before measuring.
Photograph each wall with a tape measure in the frame to confirm the numbers.
Do not move any point after the measurements are sent.
How the glass is held on the wall
There are a few general approaches, and the right one depends on the wall and the size of the panel. Large panels are heavy, so professional fitting matters. Do not try to mount a full-height sheet yourself.
Commonly the glass is bonded to a sound, flat wall with a suitable silicone or adhesive, sometimes with small clips or channels at the top or bottom to take weight and keep the panel straight. The method must suit the wall surface: bare plaster, paint and tile all behave differently, and a wall that crumbles or is damp will not hold anything well.
Whatever the method, the glass should not be squeezed between hard surfaces. A little room at the edges and a soft, flexible joint let the sheet sit without stress. Hard contact on an edge is a classic reason for tempered glass to fail later. For more on this, see why tempered glass breaks.
Edges, corners and joints
Glass edges should be finished before tempering, usually by polishing, so they are smooth to touch and less prone to chipping. Edges that meet the worktop and the wall cabinets are finished with a neat bead of silicone, which also keeps water from creeping behind the glass.
Where one sheet meets another, as at an internal corner or around a tall unit, plan the joint on purpose. A small, even gap sealed with silicone looks cleaner than glass pushed together. Around the hob, the joint position should respect the clearance mentioned earlier.
How to measure for a backsplash
You do not need special tools. A tape measure, a pencil, a spirit level and your phone are enough to prepare a good brief. We confirm everything with our own measurement before making the glass.
Clear the worktop and take off the old tiles or any loose material if you are replacing them.
Measure the width of the wall at the worktop and at the bottom of the wall cabinets, because walls are rarely perfectly square.
Measure the height at the left, middle and right, and write each number down separately.
Note the position and size of sockets, switches, hood outlets and taps as described above.
Check whether the wall is flat, using a straight edge, and mention any bumps or damp patches.
Photograph the full wall and each corner with the tape in view.
Tell us what is next to the glass: the hob type, the hood and any shelves.
Cleaning grease and keeping it clear
Glass makes cleaning easy but not automatic. Cooking oil forms a thin film which, over time, collects dust and becomes sticky. Wipe splashes soon after cooking with a soft cloth and a mild kitchen cleaner, then dry with a clean cloth to avoid streaks.
Avoid harsh abrasive pads and gritty powders, which scratch. For stubborn grease, warm soapy water and a little patience works better than force. Our general guide to caring for tempered glass and avoiding scratches covers the routine in detail.
Which setup suits your kitchen?
Situations differ, so here are the common ones and how we would approach them.
| Situation | What to think about |
|---|---|
| Renting | Ask your landlord first, because glass bonded to a wall is not a quick removal. A panel fitted behind the hob counts as a permanent change |
| Owning and renovating | Best time to fit is after the tiles are removed and the electrical points are final, but before the worktop is sealed |
| Open kitchen | The backsplash is part of the living room view, so colour and edge neatness matter more |
| Closed kitchen | Grease cleaning and heat position are the main priorities; a plain finish usually wears best |
| Gas hob | Keep flame and hot cookware away from the glass; clear the clearance first |
| Induction hob | Less flame near the wall, but the maker's clearance still applies |
Common mistakes and how to avoid them
Almost all backsplash problems come from skipped planning, not from the glass itself.
| Mistake | Why it hurts | Better approach |
|---|---|---|
| Ignoring the hob instructions | Glass may sit too close to heat | Read the clearance and share it with us |
| Measuring before the sockets are final | Cut-outs end up in the wrong place | Fix electrical points first |
| Assuming it can be trimmed on site | Tempered glass cannot be cut | Measure carefully; fabricate once |
| Pushing the sheet tight into a space | Edge stress can cause breakage later | Leave a small flexible joint |
| Using it as a fire barrier | It is not fireproof | Use correct kitchen protection where needed |
| Mounting on a damp or flaky wall | The adhesive fails | Repair the wall first |
| Choosing colour in a showroom only | Looks different at home | View a sample in your own light |

Frequently asked questions
Can I put tempered glass behind a gas hob?
It is commonly done, but only if you respect the clearance in the hob maker's installation instructions. Share those instructions with us so the glass is planned around them.
Is tempered glass fireproof?
No. It handles heat changes better than ordinary glass, but a flame or concentrated heat can still damage it, and it should not be used as a fire barrier.
Can the glass be cut for a socket after it is made?
No. Holes and notches must be made before tempering, so the socket and switch positions have to be final when you send measurements.
Is back-painted glass the same as tempered glass?
Back-painted glass can be made from a tempered sheet. Paint is applied to the back for colour. Ask us which colour options are available.
How do I clean grease off a glass backsplash?
Wipe with a soft cloth and warm soapy water or a mild kitchen cleaner, then dry. Avoid scouring pads and gritty powders because they scratch.
Can I install it myself?
We recommend professional fitting. Large sheets are heavy, the wall needs checking, and the joints must be left flexible rather than tight.
Can I fit one in a rented kitchen?
Check with the landlord first, as a bonded panel is a permanent change to the wall.
