Thanks for all the helpful advice. Will conduct further research & maybe give it a try. Worst case scenario is I'm down one countertop and revert to tiles / granite etc.

I'd like to replace my bathroom's cheap tiled countertop with solid wood but is this flirting with probable disaster given Thailand's heat / humidity? IKEA have some pre-made countertops in the right size e.g. https://www.ikea.com/th/th/p/karlby-worktop-oak-veneer-50335190/?utm_source=google&utm_medium=surfaces&utm_campaign=shopping_feed&utm_content=free_google_shopping_clicks_Kitchen If it's doable, any recommendations re best type of wood / sealant etc.? TIA
