Assuming you have a standard toilet now, it will bolt on the same way in the same position. ADA are just taller floor to seat. Most toilets are 12 inches from the back wall to the center of the drain. Older ones, before 1940 or so were 14 inches and I have come across a few odd ones that are 9 inches.
The height of a standard toilet seat is 14" from a furnished floor.
Yes... is the short answer. The toilet has a trap in itself. You would have to be able to break out the floor and put a P trap in the existing line
They are usually about 24-26 inches high
The ONLY places any toilet can leak is between tank and bowl, or between bowl and floor.
Standard height is 15" but you can get comfort height or ADA models which are 17" high. The standard toilet rough in dimension is 12", which means the outlet of the toilet at the floor is 12" from the unfinished wall, but they do make 10" and 14" rough in models. The width really depends on the type of toilet you get but remember International Plumbing Code requires 15" from the center of the toilet to the nearest wall. Hope that helps.
Kits are available to make sure the toilet flange is level with the new floor. These kits are adjustable because of the differences in thickness of flooring and material, any subflooring laid down, grout, infloor heating etc. . Ideally, you want to seat the toilet on the wax gasket, and attach the mounting bolts, and have the toilet flat on the finished floor. These kits are easy to find and use.
That depends on who is to use the toilet. children's toilet seats (in schools for example) are much lower than in an apartment and old peoples homes have even higher seats. The Swedish standard toilet height (to the rim not including any seat) is 420 mm.
The knobs on the bottom of the toilet hold the toilet to the bolts that in turn hold the toilet in place on the floor.
Yes As long as the flange does not hold the toilet off the floor it will be fine.
No,you can get sick the next time to wipe
Standard is 12 inches to the center of the pipe from the finished wall.
Change the wax seal under the toilet
