What no kitchen? No laundry? No other hot water outlets? There are sizing guides from the manufacturers websites to help choose the right model for your needs. Also climate will influence what model you choose because it will determine how much the water temperature needs to be raised from the incoming water to reach the desired level of temperature. The higher temperature change the bigger model tankless you will need.
You should have a hot water heater for the kitchen for sure and also to have for the bathrooms. I personally like to wash my hands in hot water not cold.

An electric shower head water heater works by using electricity to heat the water as it flows through the shower head. When you turn on the shower, the water passes through a heating element inside the shower head, which warms it up before it comes out of the nozzle. This provides a continuous supply of hot water for your shower.
