A stairbuilder would be able to custom turn those for you. I know the staibuilding company in my location (Staten Island) does this. You know, you might be able to sell those lucite beauties on Ebay.

Hi, I'm pretty rusty on volute turnouts, but the component they send you will have a sweeping arc at the top to accommodate any rise/run up to 45 degrees. You need to super carefully measure your stair angle and cut the sweep of the volute tangentially 90* so that it's exactly at that angle. It connects to the straight rail with a rail bolt; the joint is 90*; a butt cut. Expect to pare away portions of both abutting members to get a smooth transition. IOW if both profiles of both were identical out of the box, that would be a miracle. You want to lay out the ballusters evenly on the treads first, then plumb them up to the rail. On the underside of the rail,mark the first regular balluster, then mark the last; the neat trick is to then use a set of dividers precisely adjusted to lay out tick marks on the rail in exactly even increments. Takes a few tries to get the setting just so, but it really looks well to have them spot-on. By "regular" I mean not part of the turnout of the volute below; those are "special". I usually use a figure of 2.25" from the face of the riser to the center of the first balluster; just allow 3/4" Min. between the nosing and the balluster. The intermediate ballusters are centered exactly between those closest to the risers. Not familiar with the shoes (I work in wood) but if they fit an angle up to 45* you'll be fine, as most rails are by code far less than 45*, more typical to be in the 40* to 42* range. I would take it that these trim covers are adjustable within a logical range of angles. I have never (yet) had an inspector hassle over a semi-enclosed stair railing not being continuous. We always make sure they are at the exact same height, and that the proper returns are placed to not catch on sleeves, etc. I bet there are good online instruction manuals for ascertaining and cutting the appropriate angles for the volute/sweep. I'm sure I have confused things further, so my work here is done. Casey

I love your inspiration picture but see it more for a mountain contemporary home. I wasn't sure what Mediterranean contemporary was so did a search on it with the term fireplace. They were mostly light colors, if stone, but really more drywall and painted to blend with the walls. More of a light airy look with a minimum of fireplace treatment. Maybe consider that for now and then get your decorator to figure out if more is needed or decide later if you want to add stone or tile once you see how the rest of the room turns out.

Thank you so much for posting! I really appreciate your boost! That is the plan for the newel as well. :) I like what you did a lot! The handrail - did it go okay from the catalog? It looks really well done! Not sure if you remember this part but there are just a few profiles and I am just checking that you got one of those or had that also custom? Because the fits over caps beautifully is starting to be delicate to me. You have super beautiful caps all on beautiful newels I see!!
