This was so easy to install as long as you have electric available. I drilled a hole behind the toilet into another room so I could get electric. 
I have a traditional bidet but had to get off the toilet to move to it. That included taking my pants off to be able to straddle to hit the right spots. First you had to wipe yourself before hopping to the bidet and then wipe to dry yourself once done. More of a pain than it was worth. This Toto seat is one stop shopping that includes air drying plus a heated seat in winter. No toilet paper needed ever again except to blow my nose. 
Only way to sit and enjoy reading the morning news.
