Planning on a full bathroom remodel of my master bath this fall. The plan is to tear out the 80s blue fiberglass shower stall (made by Aqua Glass) and build a new stall using Schluter products. My main issue is the drain on my current shower is located near the wall where the shower valve is located, similar to where a tub drain is located. The pre-fab floor pans by Schluter seem to be all made with the drain in the center. I could go with a trough drain in this location, but can't seem to find any photos of a pre-fab Schluter linear drain floor pan. Is this something Schluter would have to custom make or do you just get a large piece of sloped Schluter floor pan and cut it and piece it in so it slopes towards the linear drain from both sides? I can't move the current drain location without tearing up the floor or the kitchen ceiling below. Neither one is an acceptable option. I also don't want to do a mortar bed, rubber membrane or hot mop application, so in essence I'm looking for a simple solution and the Schluter system seems to be the best option if I can get the drain issue worked out. Thanks for any suggestions or links to photos of a similar project.

Want to change out cartridge on my shower valve as I'm not getting good hot water flow. There is clearly no hex screw or traditional cap on this handle. Any thoughts? Still trying to figure out how to post picture.
