A kitchen backsplash is not just decoration. It protects the wall from water, grease and cleaning damage. The right height depends on what happens in that zone: chopping, boiling, washing up, kettle steam, pan splatter or a full cooker hood line.
Kitchen splashback height table
| Splashback type | Typical planning height | Best use |
|---|---|---|
| Low upstand | Often around 100mm | Dry prep areas where the main aim is protecting the worktop to wall joint. |
| Sink splashback | Often 300mm to 600mm, or up to the window sill or wall cabinet line | Behind sinks, kettle zones and dishwashing areas where water hits the wall. |
| Hob splashback | Often from worktop to cooker hood or wall cabinet line | Behind gas, ceramic or induction hobs, using material suitable for heat and grease cleaning. |
| Full-height splashback | Worktop to underside of wall cabinets, shelf or ceiling feature line | Modern kitchens, open shelves, messy cooking zones and easy-clean feature walls. |
| Window return splashback | Height follows sill, reveal and sink position | Kitchen sink under a window, where water can damage reveals and sealant. |

Use this before ordering tiles, glass or panels. Final clearances still depend on appliance and material instructions.
Which height suits each part of the kitchen?
Dry prep run
A low upstand can be enough when the wall is not taking much water or grease. It also keeps the kitchen lighter and reduces tile cost.
Sink run
Water finds weak sealant. Raise the splashback enough to catch normal washing-up spray and protect window returns or wall corners.
Hob run
This zone needs heat-safe, wipeable material and enough height to deal with pan splatter. Follow the hob, hood and splashback material instructions.
Feature wall
Full-height panels or tiles can look cleaner around open shelves and strong cabinet lines, but sockets, cuts and edge trims need planning.
Material notes for common splashbacks
| Material | Strengths | Watch out for |
|---|---|---|
| Tiles | Flexible around sockets, windows and awkward walls | Grout needs sealing and cleaning. Small cuts around sockets can look messy if not planned. |
| Glass | Clean single panel look, good behind many hob layouts when specified correctly | Measure only after walls and worktops are ready. Use suitable toughened glass where heat is involved. |
| Laminate upstand | Cost-effective and matches some worktops | Not always suitable directly behind all hobs. Check manufacturer restrictions. |
| Quartz or stone | Robust, simple joint line with matching worktop | Heavy and templated. Socket cuts and tall panels need accurate measuring. |
| Stainless steel | Practical behind cooking zones and easy to wipe | Shows fingerprints and scratches. Edge detail matters. |

Measuring sequence before ordering
- Confirm worktop height and thickness first.
- Mark the underside line of wall cabinets, shelves or cooker hood.
- Mark sockets, switches and fused spurs so cuts do not land on awkward edges.
- Choose the highest-risk zone: dry prep, sink, hob or full-height feature.
- Check material restrictions around heat, steam, water and cleaning products.
- Template or measure after plastering, cabinet fitting and worktop position are stable.
Sources and checks used
- Hob, hood and splashback manufacturer instructions should be checked for heat, clearance and fixing limits before ordering.
- Electrical Safety First kitchen safety guidance is a useful safety reference when sockets, appliances and wet areas are close together.
- For fitted kitchens, final dimensions should be checked after cabinets and worktops are installed because walls are rarely perfectly straight.
Regulation checks that affect splashback height
There is no single Building Standards rule that says every kitchen splashback must be one fixed height. The checks become important when the splashback sits near sockets, wet zones, hobs, ventilation or altered wall construction. In Scotland, use the Scottish Government route as the compliance reference, then check manufacturer instructions for heat, water and fixing limits.
- Scottish Government Building Standards: compliance context when kitchen work is part of a wider alteration.
- Scottish Building Standards Technical Handbook: domestic reference point for safety, services and moisture-related checks.
- Electrical Safety First kitchen safety guidance: useful where splashbacks, sockets and appliances sit close together.
FAQ
How high should a kitchen backsplash be?
A low upstand is often around 100mm, but sinks and hobs usually need more protection. Many kitchens use full height from worktop to wall cabinets or cooker hood in the busy zones.
Is a 100mm upstand enough behind a sink?
It can be too low if water regularly splashes the wall. Behind a sink, consider a taller splashback, a window-sill line or full-height protection depending on layout.
Can laminate upstand go behind a hob?
Do not assume it can. Check the worktop and hob manufacturer instructions for heat clearance and material limits before using laminate behind a hob.
Should splashback go before or after worktop?
Usually after the worktop position is confirmed. Accurate splashback measuring depends on the finished worktop line, cabinet line and wall condition.
