This post is going to be weird. I adore my host family’s bathrooms! Their toilet seat is heated! The toilet has an entire control panel on the wall with three different bidet settings, all with different strengths. You can also adjust the heat of the bidet water and toilet seat. I also have enjoyed the Japanese style of bathing. They have a shower room with a tub. Unlike American bathrooms where you stand in the tub with the shower head above you, Japanese shower rooms have two-level hooks for the shower head next to the tub with a mirror. They let the tub fill and heat up while doing other tasks. You know when the tub is ready because a panel in the kitchen plays a cute song to alert you the tub is full and ready at 40 degrees Celsius. They keep the tub covered during the shower so nothing gets in. You shower first and ensure you are squeaky clean, and once you are clean you soak in the bath. Because the water heats itself and continues to heat up so that it doesn’t get cold, and everybody gets in clean, a single bathtub of water is shared between the entire family. It is very relaxing, like a hot tub but without the chlorine. I greatly enjoy this arrangement, but I know some Americans feel uncomfortable sharing bathwater with others. If you are an American who is uncomfortable sharing bathwater, do not go to an onsen/the hot springs if you visit Japan.
