Residential bidet

I have installed several in RVs. Piece of cake if you have a toilet with standard style seat bolts (domestic 310 or other similar). Most toilets are plumbed with pex pipe 1/2 inch so a simple sharkbite T with a valve and 3/8 male is all you need. The bidet at Lowe’s has a standard 3/8 water line and screws right on. Other brands (bio bidet comes to mind) have proprietary threads that must screw onto one of their Ts and can be a little more involved. The supplied T is for 7/8 thread for the cold water tank connection at your S&B, but you can usually request a HOT water T and it will be standard 3/8 thread and you can splice it in with a male and female 3/8 thread to 1/2 inch pex sharkbite.

Anyone that thinks a bidet in an RV is a bad idea has never tried one. Uses very little water and you use as little as 2 or 3 squares of TP per use. These things are awesome for your black tank.
