Need Advice: Letting a tenant install a new toilet?

[Josiah McGinnis]

My new tenant just asked me if I would allow him to pull out the old toilet install a new high-efficiency toilet. He said he would cover all expenses, and hire a plumber to do the work. He even recommended I write up an official document that states what work was being done, that he would cover all expenses, and that he would leave the new toilet in place upon vacating the property at the end of his lease.

Does anyone have experience with handling situations like this? Are there reasons why I should not allow my tenant to proceed with this project?

Thanks in advance for the advice!

Sounds like a pretty sweet deal.  How about going through with all of it except you get to pick the licensed plumber, that way you know it was done right and you have some recourse if it isn't.
