Currently tying up a complete barebones remodel of my bathroom in a 1939 home. This is all DIY and I am doing a lot of the learning along the way. I learned recently that the location of the toilet drain pipe was going to pose a huge problem for me since the rough in plumbing is 16" from the wall. I found this out after placing the 12" toilet that I had purchase in place over the flange to get a feel for what it was going to look like. The tank is approximately 4" off the wall.
My question is this; can a toto 14" unifit be modified by adding a 2" section of ABS to it to make it work for 16" rough in? Would the resultant unifit fit beneath the toto toilet's skirt? We are considering the Guinevere right now.
Plumbing is the cast iron stuff and there is room to move it (not against a floor joist) but I'd really rather not seeing how we just finished tiling the floor.
