I am reinstalling a shower door in a shower with an acrylic (or similar) shower pan and ceramic tile walls. I'm thinking about caulking the shower pan and tile, letting that dry, and then installing the shower door but I'm not sure if that's the best way to do it. Here's where I'm coming from (correct me if I'm wrong): 1. I hate silicone and want to use it as little as possible, so I'm going to caulk the shower pan-to-tile joint with Polyseamseal. 2. Only silicone can be used under shower door threshold (is there anything else? Polyseamseal instructions say not to use it here). 3. Nothing sticks to dried silicone, not even silicone, and silicone doesn't stick well to other caulk. This is really the root of the problem, and I've never seen it addressed in shower door installation instructions. Unless you use silicone for everything AND do all the caulking at the same time the shower door is installed, you are going to have some place where two things meet that don't really want to stick to each other. The choice I am pondering: A. I could caulk the entire shower pan with Polyseamseal before installing the shower door. This will mean that there is Polyseamseal behind the shower door frame in the corner where the shower door threshold and vertical support meet. But if I do it right this part shouldn't get wet. I think I'm leaning this way. B. Or would it be better to install the shower door first, using silicone on the tub/tile joint behind the shower door frame only, and then after that is dry caulk the rest of the shower with Polyseamseal? This means that the only material behind any part of the shower door frame is silicone, which may be a good thing. But it also means that there will be a Polyseamseal-to-silicone butt joint in the shower door/tub/tile corners, and I don't know how well that will work. Thanks for any advice you can give.

I currently have a kitchen island that is at regular counter height. I would like to add an L-shaped bar height countertop around the outside of the existing island. I am looking to frame the walls for the L-shaped. Then to finish we'll add door panels and corbels to support the countertop. Should I frame the L wall using 2 x 4 or 2 x 6 lumber? I'm leaning toward 2x6 to give the wall more depth but looking for opinions.
