Y'all're knuckledraggin' cavemen.
Even my knockabout Chris Craft Commander 42 is outfitted with Panasonic washlet toilet seats. I put them on my wooden Connie 52 before that, and they're ready to install on my Roamer project boat, too.
Japanese bidet toilet seats make anything less simply uncivilized. There are 100% no-touch versions that, with a push on a single remote control button will clean you up even after a spicy burrito bowl toilet-wrecker and dry with precisely directed, perfectly warmed air. The more pedestrian models I use require a few squares of cheap single ply to blot dry, not for fecal residue removal. Ever. And if you loaded up on deep fried jalapeno cheese sticks the night before, there's a turbo button. Literally.
You want cool, ambient 'shower' water in summer but warmer spray when autumn sets in? Yeah...they do that. The seats are also heated or not. Just set it at the temp you like. Oh, and even the most basic models have hydraulic seat-lowering.
Women have special...needs. There's a button for that, too, that puts a different spray pattern in just the right spot (or so I'm told), which lessens female TP usage, too.
Ironically, all of the hifalutin/$$$ Vacuflush heads I've seen have proprietary seats, so nothing else can be attached to them. My Panasonic washlets work great on pretty much any kind of grinder head.
YMMV
