A raised toilet seat, a raised small for use in shower (Pitchcombe GL6)

My dear man has just had a very major operation and is about to come home after 11 days in hospital. He is still struggling to wash himself in the shower without grab rails or walking frame as stomach muscles are dreadfully bruised and sore from operation. So lowering oneself onto toilet seat or sitting to enable near proximity to wash legs and feet is still tricky. So a stool or walking frame to steady himself and a raised seat so it's not so far to sit down for toilet would be jolly handy. Has anyone got anything like that that they no longer need or use please?
