Why not Freegle the equipment - and the incontinence aids? I am sure there will be someone who will snap them up.
The Red Cross rental system is fantastic. When my aunt was discharged from hospital, just dumped at home, unable to even rise from a chair and with no equipment to help her, I just rang DH sent him down to the local Red Cross and he arrived at my aunt's home an hour later with two walking frames, for upstairs and downstairs, elephant legs to raise her chair, so she could get up and a frame for the loo. All collected from the Red Cross, with no notice at all.
