My idea was to saw off the bottom 4 inches and build a little square plinth underneath. But what to use?
One idea is to simply cast in place with concrete, then get the waterproof membrane a couple of inches or so up the concrete sides before tiling. Anyone used this method before? Any problems to anticipate?
Another idea is to put an undersize block of wood under the post, then seal the sides and smooth to match with Bondo, WoodEpox or some such. I have never tried this before either?
I would most appreciate your thoughts and experience on this.
