I'm at my wits end, thinking that building a pedestal for the base of my toilet is the only option
The situation: 1912 house with 1/2" for every 15" slope in floor from outer wall to bathroom door with toilet tank oriented in direction of slope, cast iron main stack, original plumbing except for cast stack recently replaced with copper, drain system in bathroom replaced with ABS, new 1" plywood floor installed but not leveled by contractor (possibly due to large step that would result at hallway entrance to bathroom?), 3/8" subfloor and ~ 5/16" tile/mortar installed up to drain pipe.
The problem: underfloor depth and toilet distance from stack make it so that I have no standpipe; there is ~ 15" of sloped drain pipe (ABS) attached to original cast stack and then the 45 deg elbow whose top edge sits ~ 0.8" below the finished floor - a 3X4 closet flange can only be inserted 1 5/8" max into the elbow due to elbow depth and change in OD of flange (bulged portion which creates wax ring bed.)
Short of creating a platform e.g., concrete pad/pedestal for the entire toilet, I see no other way to screw the closet flange to a flat / level surface nor ensure that the toilet is sitting level.
