Shower

Any advise on the following
Would a shower head controlled by a manual mixer tap supplied by 12kw instant water heater provide the same output as a 12kw electric shower. The instant water heater will also supply a basin tap but not at the same time as the shower
This would save me having to purchase a separate electric shower if the water heater can perform the same as an electric shower
