I am finding a contractor to install a wall-mount fold-up shower chair in the toilet before she gets discharged. We got the shower chair via subsidy from the hospital. My grandma became immobile and we need someone with experience to fix the shower chair. Should I get a HDB approved contractor or would a handyman suffice? Any suggestions of contractors/handyman who can do the job? We need reliable installer as my grandma has fall-risk.
