Question: What's included in this package and what additional items would I need to order for a complete installation?
Document: This is the first in wall tank system that I ever got my hands on so I cannot tell you how it compairs to others. However the quality of this is outstanding,  instructions clear and instructional video is also available via YouTube for people like me who learn and understand better from visual point. Everything is included for the installation unless you live in a state that requires you to install cast-iron waste pipe. I am not a plumber and installation was easy.
Can't personally complain because I got my system on sale. Hope this review is helpful.
If you have a small bathroom, a wall mounted toilet will make the room appear much bigger. Plus it will be easier to clean. I had a plumber install it.
Replacements parts are not currently available for this toilet. Connection on the waste side can be tricky and without replacement parts the project will come to a standstill.
Answer: no
