Kitchen Splashback Height: What Works and Why
For most UK kitchens, a splashback runs from the worktop up to the underside of the wall units, which is usually 450mm to 600mm. Where there are no wall units, around 600mm is the common choice. Behind the hob it often goes higher, up to the extractor. A short upstand of about 100mm is the minimum for a dry run of worktop. The right height for your kitchen depends on what sits above the worktop and how much of the wall you actually see.
That is the quick answer. The rest of this guide helps you choose the line for your own room, avoid the mistakes we see in kitchen projects, and plan the height before the worktop and wall units go in, when it costs least to change.
TL;DR
With wall units, tile or panel the whole gap between worktop and units: typically 450mm to 600mm.
With no wall units, about 600mm is the usual working height. Stop at a natural line such as a window sill, or go to the ceiling.
Behind the hob, go up to the extractor or hood. This is the splash and grease zone.
A 100mm upstand is a minimum for dry areas, not a premium finish for wet ones.
Decide the height before the kitchen is fitted, because the worktop, sockets, units and splashback all depend on each other.

Is there a standard kitchen splashback height in the UK?
There is a common range, not a rule. One UK guide to splashback heights puts it plainly: there is no single correct height. It suggests a 100mm upstand for a dry worktop-to-wall joint, 300mm to 600mm in sink and kettle zones (or up to the sill or wall-unit line), and a run from worktop to extractor behind the hob. A tile retailer’s splashback guide quotes a standard height of 450mm to 600mm, which matches what most UK kitchens end up with.
Why that range? Standard base units and worktop put the working surface at roughly 900mm from the floor. Wall units are usually hung so their underside sits between about 1,350mm and 1,500mm. The gap between the two is 450mm to 600mm, and in a conventional kitchen the splashback simply fills it.
If you have seen 4 inches, 6 inches or 18 inches quoted online, that is mostly American advice. A US-style 4-inch backsplash is roughly 100mm, which is really just an upstand. In a British kitchen with wall units, an upstand-height splashback leaves a strip of bare wall between the worktop and the units that is hard to keep clean. Think in millimetres and in the gap you actually have.
Situation | Typical height above worktop | Notes |
Dry worktop, no cooking or water | About 100mm upstand | Protects the wall joint, minimal look |
Worktop with wall units above | 450mm to 600mm, to the underside of the units | The most common UK layout |
Run with no wall units | About 600mm, or to a sill, shelf or ceiling | Choose a line that has a reason to be there |
Behind the hob | Up to the extractor or hood | Check appliance clearances in the manual |
Around the sink under a window | To the sill, often with a tiled reveal | Keep the junction watertight |
Statement or modern look | Full height, worktop to ceiling | More material, bigger visual impact |
Splashback height by zone
A kitchen is not one uniform wall. It helps to treat it as zones, because each one has a different job.
Behind the hob
This is where fat, steam and splatter do the most damage, so it is the area to protect fully. A UK splashback planning guide makes the point that the right height depends on what is above the worktop and how much of the wall is genuinely visible. In practice, that means the covered area behind a hob should reach the extractor or hood, with no gap of bare painted wall that will stain.
What about clearance between hob and extractor? That is set by the appliance manufacturers, and the figures differ between gas, induction and different hood types. Read both manuals before the splashback is cut. Do not guess from a general article, including this one.
Around the sink and tap
Water splashes are less greasy but more persistent, and the real enemy is moisture creeping into the joint between worktop and wall. A sink under a window usually takes the splashback to the sill. If the sink sits on a plain wall, 300mm to 600mm is a sensible range, depending on how far your taps throw water and whether you have wall units above.
Tap position matters here too. A tall mixer or a wall-mounted tap changes where water lands. If you are choosing taps at the same time, it is worth checking tap hole sizes for basins and kitchen sinks before the worktop is cut, so the fixings and the splashback line agree.
Dry runs, coffee stations and tall units
Where a worktop is only used for food prep or small appliances, a lower splashback can work. A 100mm upstand, in the same material as the worktop, gives a neat, practical finish. Between tall units or in a short run, you can often keep it to 300mm to 450mm and let the wall colour do the rest. Just keep kettles and toasters in mind, as steam climbs the wall under units.
When there are no wall units
Open walls are where most height mistakes happen. With no units to define the top edge, you choose the line. Around 600mm above the worktop is a typical working height, but a tile border floating in the middle of a wall looks accidental unless it relates to something.
Good anchors for the top edge:
The underside of a window sill, so the line carries across the wall.
The top of a door or window reveal.
The height of a shelf or open shelving run.
The top of the extractor or a chimney breast feature.
The ceiling, for a full-height finish.
Full height is growing in popularity. One 2026 trends round-up notes that the standard 18-inch backsplash is giving way to counter-to-ceiling installations, especially behind ranges and around open shelving, at a higher material cost but with a strong visual effect. If you like the look, it is a good option for a feature wall, but budget for the extra tile, slab or panel and the labour of cutting around sockets and switches.
Upstand, half-height or full-height: which suits you?
The upstand
A short upstand is a few centimetres of worktop material turned up the wall. It is tidy, hardwearing and often the most cost-effective choice. It suits dry areas and minimalist kitchens, and it works well with solid surfaces. It is less suitable behind a hob or sink, where the splash reaches far above it. If you are still choosing worktop material, our kitchen worktop comparison covers how the main options behave in daily use.
The standard-height splashback
This is the 450mm to 600mm option that fills the gap to the wall units. It gives the best balance of protection, cost and cleaning. Whether in tile, glass, stone or a solid panel, it also gives you a clean, finished look, because there is no bare strip left between worktop and unit.
Full height
Going to the ceiling makes a kitchen feel taller and more deliberate, and it removes the awkward dust-catching strip above units. It costs more, and the material choice matters: large-format tile, glass or a slab with few joints keeps cleaning easy. Check that the wall is flat and sound first, as a full wall of tile or glass shows every ripple.
Planning the height before the kitchen goes in
Splashback height is a design decision that affects the rest of the room, so settle it early. Here is the order we recommend.
Fix the worktop height and the wall unit height. Together they set the gap. If you want a taller or shorter gap, move the wall units now, not after the tiles are up.
Choose the material. Tile, glass, stone, solid surface and panels have different thicknesses and edge details. That changes how they meet the worktop and the units.
Mark the hob, sink and socket positions. Sockets, switches and any under-unit lighting need to be placed with the splashback in mind, so you are not cutting holes in finished tile.
Decide the top line. With units, it is the underside. Without, pick a sill, shelf or ceiling line.
Plan the junctions. The joint between worktop and splashback is normally sealed with silicone rather than grout, so it can flex without cracking.
Fit in the right order. Some kitchen manufacturers advise that tile or glass splashbacks can be fitted after the rest of the kitchen. The installation manual for one UK kitchen range says the splashback can go in last, with the bottom edge below the worktop line so the junction is covered. Always follow the manual for your own units.
If you want the wider sequence, our kitchen fitting step-by-step guide and our kitchen renovation workflow show where the splashback sits in the programme.
Sockets, switches and electrical work
Sockets above the worktop are the detail that most often upsets a tidy splashback. Moving them after tiling means cutting into finished work. Moving or adding circuits is also regulated: Bolton Council’s guidance says work that adds a new circuit to a dwelling, or electrical work in kitchens and other special locations, must either be notified to Building Control or be carried out by a competent person registered under a scheme. Milton Keynes Council gives similar guidance. Ask your electrician about it before first fix, and keep the paperwork. Local authority wording varies, so check with your own council’s Building Control team.
Perspective: what we see on London kitchen projects
We fit and refurbish kitchens across West and Central London, and splashback height is one of those small decisions that shapes how the whole room feels. Many London homes have period walls that are not perfectly flat or level, and ceilings that are not the same height on both sides of the room. That matters when you take a splashback to the ceiling or run a line across a wall, because a line that looks level on paper can drift against a real wall.
Our advice is to settle the splashback before anything is ordered. Sit down with the layout, the worktop choice, the appliance manuals and the socket plan, and agree one set of heights. With in-house project management and director oversight on our jobs, one team keeps those decisions connected rather than passing them between trades. That is how a finished kitchen ends up looking designed, with no odd strips or cut-around-socket compromises.
On height itself, we tend to suggest filling the full gap to the wall units in a conventional kitchen, taking the hob wall right up to the extractor, and using full height only where the wall is flat and you really want that statement. A 100mm upstand is a lovely, practical detail for the right worktop, but it is not our first choice behind a hob or sink.

Common mistakes to avoid
Stopping short behind the hob. A splashback that ends a hand’s width below the extractor leaves painted wall to take the grease. Take it up to the hood.
Leaving a bare strip under wall units. A 100mm upstand beneath units leaves a gap that collects dust and splashes. Fill it.
Floating the top line. An arbitrary line at, say, 700mm on an open wall looks like a mistake. Align with a sill, shelf or ceiling.
Forgetting socket positions. Mark them before tiling, with the finished thickness in mind.
Grouting the worktop joint. It will crack as the worktop moves. Use a flexible sealant.
Ignoring appliance clearances. Hob and hood manuals set the minimums. Check them before cutting anything.
Choosing material last. Tile, glass and solid panel have different thicknesses and edges, which change the junction details.
A worked example
Take a typical London terrace kitchen. Base units and worktop put the surface at about 900mm, and the wall units hang with their underside at about 1,450mm. That gives a 550mm gap, inside the usual 450mm to 600mm range. The splashback fills that gap along the whole run. Behind the hob, where the extractor sits higher, the same material continues up to the hood. Under the window the sink wall is tiled to the sill, with the reveal tiled too. Along a short stretch of open wall by the door, you could stop at 600mm, but it looks better stopped at the sill height so the line runs through the whole room.
The cost of the extra height is small compared with the benefit of a continuous line. The cost of getting it wrong is cutting out and redoing finished tile, so measure twice and agree the drawing with everyone on site.

FAQ
What is the standard height for a kitchen splashback in the UK?
Most UK splashbacks run 450mm to 600mm above the worktop, filling the gap to the wall units. With no wall units, about 600mm is typical. A short upstand of around 100mm suits dry areas only.
Should a splashback go all the way to the wall units?
In most cases, yes. Filling the full gap gives the best protection and avoids a strip of bare wall that collects dust and splashes. The exception is a deliberate design choice, such as open shelving above a lower splashback.
How high should the splashback be behind the hob?
Take it up to the extractor or hood, as this is where grease and steam hit the wall hardest. Check the hob and extractor manuals for clearance requirements before cutting the material.
Is a 4-inch (100mm) splashback outdated?
Not outdated, but limited. A short upstand is a clean, practical detail in dry areas and with some worktop materials. Behind a hob or sink it offers too little protection, so most people choose a taller splashback there.
Is full-height splashback worth it?
It can be, particularly behind the hob or on a feature wall. Current trend reporting points to more counter-to-ceiling installations. It costs more in material and labour and needs a flat, sound wall, so decide on it at design stage.
