I am looking to build a wishing well similar to the photo 36" across and 5' tall. I can't find any plans online it appears you need to purchase certain plans which I found a little odd might not be legit. I know pressure treated wood is good for outdoors but I love the look of this or cedar but I also do not want to have an issue with rotting wood in years to come. The area is a slight incline so I will sit it on a pressure treated base opened bottom. Any ideas greatly appreciated.
