The cabinet in our outdoor entertaining area is all solid timber.
Our area is reasonably exposed and we built a small wall to give the cabinet some shelter so it doesn’t get rain on it directly, but the floor 300mm in front of it does get very wet in storms.
I guess our climate is a little different to yours, but during our wet months one side of the house doesn’t really dry out for many weeks. At this time the timber swells a lot and half of the doors become very hard to open and close. The drawers aren’t that bad.
This summer I expect I’ll rip all the doors off and give the edges a hit with the plainer.
I expected some movement with solid timber, but didn’t expect it to swell as much as it does.
I haven’t built my bench top yet, but when I do I’ll be using some thick Fibro sheeting and tile the top of it.
