Old 4-bolt to new 2-bolt toilet upgrade question...

Old 4-bolt to new 2-bolt toilet upgrade question... Need to replace current with new toilet. Been told cheap 4 to 2 bolt adapters are junk and good ones are not cheap. I have replaced and repaired ...

2 bolts of the old 4 bolt should be in same location on floor flange as new 2 bolt toilet

Just remove old bolts and reset new toilet with new floor gasket using existing floor flange and new T-bolts


Provided the flange centerline is far enough away from wall to accommodate new toilet dimensions
