Help Peter build a walk in shower due to Covid19

My husband Peter was diagnosed with COVID 19 on March 30,2020. He was admitted and intubated on April 9,2020. He spent several weeks in Kenner ICU. On May 18th he was discharged to Ochsner LTech rehab. On September 11th Peter was discharged from Ochsner with disability’s of not being able to use his extremities due to COVID . Peter is now in extensive occupational and physical therapy due to his illness. Peter lost conciseness multiple times along with the lost of feeling throughout his body. Peter has learned to talk,eat, and is in the process of learning to walk again. I would love to remodel our home bathroom so that he could have a walk in shower so that he can continue his therapy with keeping up with his personal hygiene. We would appreciate any help from friends, strangers and family members. Thank you and God bless.
