If none of these materials is available to you you can always elect bathtub replace to soak rags or towels in hot water and wrap them around the frozen pipe. This will probably take longer than any of the methods previously mentioned.
The wax ring is used to seal the drain outlet on the bottom of the toilet to the drain opening in the floor. When a toilet is installed, the ring is placed onto the drain... the toilet is dropped onto the ring... and the toilet bolts (also known as closet bolts) are tightened enough to lock the toilet in place. If that wax gasket ring starts to fail or isn't seated properly? Sewer gasses can sneak out from under your toilet causing your bathroom to have that suspicious smell. It can also cause water line repair to escape, sometimes invisibly, with each flush potentially damaging the floor hidden under the toilet.
The con to time well spent is only if the fix or installation works. Suddenly, when a pipe is squirting water or the dishwasher is leaking all over the floor, that time seems wasted instead of well spent. Now your time is wasted, plus you have to pay for a professional plumber to come over and fix the mess. That time could have been spent doing something else, like golfing or swimming or gardening.

Be certain that the bathroom exhaust fan vents to the outdoors, not into the house or attic. If the exterior vent dampers don't operate properly or water line repair don't seat well have them fixed or replaced.
If you do in fact choose to replace it, there is a good chance that you have an Aqua Magic IV which is no longer produced and has been replaced with the new Aqua Magic V. If you are replacing your toilet and have the Thetford Aqua Magic IV, there are other options such as the Thetford Aqua Magic Style Plus or Thetford Bravura Toilet as well as choices from the Sealand line of toilets. You will have to choose whether you want a hand or foot flush, and whether you want to stay with plastic or upgrade to china. You will also have the choice of adding a water saver. Regardless of which choice you make you will most likely be happy with the quality and dependability of any product available.
Find out if the plumber works on a 24 hour basis and, if so, what are the extra charges involved. More important than the costs however are the person's trustworthiness and reputation. After all, he or she will be in your home and around your possessions. You should feel comfortable with their presence and confident that they are honest.
