Shower head suggestion

Hello,

My mother is quite old with balance issues. She has a difficult time managing the hand-held shower head we bought her. She finds she needs to use two hands to activate the spray.

Is there a brand you can recommend that is easy to use for people with hand grip issues? She does not need any fancy settings. Just something that she can hold in one hand while soaping up or holding on to a grab bar with the other.

Thank you,

Eve
