Since you're a bidet fan, get an electric one with all the bells and whistles for your whistle! It's a game changer for sure. Oscillating spray head, courtesy flush....

I'll give you guess what I'm doing right now.

Why is your bidet hooked up to the hot water line? Toilet bowls are usually fed by the cold water line and retrofit bidets usually tap into that. If you have to dial down your hot water heater to not burn your ass, it may not be hot enough for other tasks like dishwashers and washing machines. Manual bidets are meant to be hooked up to your cold water not hot cuz of the burn risk.

Get yourself a bidet that has a built in tank and heating element. It will warm the cold water just enough to be comfortable plus that have a drying function to dry your rear after the wash cycle is done. Plus other features like a seat warmer, nightlight, self clean feature, misting, etc.
