Wanted to share Avery DIY shower chair with everyone. It’s awesome to have macguyver at home! He cut the ends off the plastic chair. Made a PVC base and screwed the legs to the chair and then used a heat gun to shape the legs to take the pressure off.  I use the green stretch band around her chest and back of the chair and a piece of shelf liner on the seat so she doesn’t slide around. Works great and cost $20 instead of hundreds!!! He is going to add lockable wheels so we can use it outside the shower as a chair around the house.
