Hollow bolts project from clamping plates to be received through mounting holes in an upper male flange section and through mounting holes of a toilet base. Base bolt nuts are tightened onto the hollow bolts to secure the upper male flange section to the toilet base prior to lowering the toilet and the upper male flange section into engagement with a lower female flange section. Fastening bolt structures with adjustable-length body portions and threaded tips can pass through the hollow bolts and into threaded engagement with mounting members fixed to the lower female flange section fixed to the wastewater pipe and the floor. Alternatively, fastening bolts pass through the hollow bolts and into threaded engagement with upstanding registration and locking rods retained relative to the lower female flange section. ## Claims ### Claim 1 A telescoping toilet mounting assembly for connecting a toilet with a toilet base with first and second spaced mounting holes and a wastewater discharge port to a floor and a wastewater pipe, the toilet mounting assembly comprising: a lower female flange section with a ring portion and a tubular wall portion;
