I use an electric bidet robot thing that has a hot water tank, heated seat, heated air drying, and the nozzle can move around. Bliss! Fortunately there is a GFCI outlet right above my toilet so the installation was easy. You remove the old seat, attach the bidet seat, plug it in to the outlet, and install a tap on the water line that goes to the tank. As long as you can see the shut off valve to turn it off it is super easy. I did have to replace the water line to the toilet tank tho because the one that was installed was a hard plastic line that couldn’t bend to give space for the “T” tap fitting. As the other commenters have said, a bidet won’t entirely eliminate the need for toilet paper. Even with heated drying you will need a little bit to dry off, and depending on your diet the water may not get you 100% clean the first time. I will say tho it has been about 10 months since I last bought toilet paper – one roll can last me weeks. I will never go back to using just TP now I’ve experienced that bidet life – the difference in perceived cleanliness is just too huge. Imagine putting your hand in dog poop and wiping it with just dry TP. Would that feel clean to you? And its so much more comfortable.
