Can you give me instructions on building a barrier-free shower?
Showers are tricky for designing a barrier-free home. If your elderly is wheelchair-bounded, think of the entrance and the space in the shower. Otherwise, you will need a comfortable seat under the shower. Install drains appropriately so no water would remain after using the shower to avoid odour and mildew. Also, you have to think of the floor to not be slippery for the safety of your loved ones.
