You'll definitely need adjustable wrenches, like the 12-inch crescent wrench mentioned, for tightening nuts and supply lines. A putty knife is crucial for scraping off old wax, and a sponge along with a bucket will help manage any residual water during removal. Don't forget towels for spills!

Always shut off the water supply completely and flush the toilet until both the tank and bowl are empty to prevent water damage. When lifting the old or new toilet, bend with your knees and use proper lifting techniques, or have assistance, as toilets are heavy and awkward to maneuver.

Place the new wax ring precisely onto the toilet flange, ensuring it's perfectly centered over the drain opening. When lowering the toilet bowl, aim directly down onto the ring without twisting or rocking, which can break the seal. Tighten the mounting bolts evenly and gradually, alternating sides, to compress the wax uniformly.

Yes, toilet installation is considered a beginner-friendly DIY project, but it requires careful attention to detail. While the estimated time is 4 hours, a beginner might take a bit longer, so plan for 4-6 hours to account for preparation, unexpected issues, and the learning curve.
