We have only showers. DS showers with us and we have bath toys on the floor. We put a toy or facewasher over the drain and just periodically let water out but let it get to about an inch and a half which is enough to splash in for him. We usually direct the spray away a little and then have a sit on the shower floor with him and have a play for a bit. Then the other parent sometimes comes to get him out so the showering parent can wash hair, shave, whatever, without worrying about shampoo in little eyes etc.
