We offer standard lengths matched to kitchen furniture and you would need to use the next larger length. A custom size would also be more expensive than standard lengths.
PREMIUM version: In the corners, the kitchen splashback should definitely be separated, as it cannot be bent around a corner well.
The material can really be cut very easily with sharp scissors. (Recommendation: Dahle Professional 50010 or a sturdy kitchen scissors)
The corners can be sealed with a bit of silicone or a corner profile from the hardware store if desired.
P.S.: Due to production reasons, we can make a maximum length of 500cm
