It is important to keep in mind that wood is a natural product and can be damaged and affected by various factors. Due to the nature of the wood and the production procedure of the worktops, the most important factors that should be considered are heat and humidity.
Trees tend to have moisture levels between 70-90%, depending on the season. That is why the wood is usually sponge-like when exposed to water. During the worktop production process, the wood is dried down to a moisture level of 8-9% and is kept away from areas with high humidity or high temperatures. Otherwise, it is possible for it to bow and warp.
Make sure that you store your wooden worktops in a place that is neither too dry, too humid nor too warm
