"Lack of provision for patients with stoma"

I was recently an inpatient at QEUH.  Patients there have individual rooms with private facilities.  I have a stoma which I self manage which was not connected to my stay in hospital.  There is no provision for stoma changing in the patients’ toilets.  At one point I was confined to bed and left to change my stoma bag, sitting up in bed.  This could have been disastrous. As private facilities are provided why couldn’t they incorporate a shelf for bags etc and somewhere other than the toilet or the shower seat to sit.
