Scooter, thanks for the vote of confidence. I don't know if anyone would want to read such a boring book. But, I suppose I could help it by pictures.
Thomas, will be very happy to offer thoughts and suggestions. You are one of those that I think of when I look through these issues.
Ron, thanks for the link. That's a great shower. Some thoughts about it.
First, the controls are near the seat. Excellent. Shower head is located within reach of person sitting on seat.
Secondly, the shower is wheelchair accessible and looks nice. The drain is located in a excellent place without much serious modification.
Thirdly, the seat is only good for those who don't have any incontinence issues. For those who have incontinence issues, a seat with a bucket underneath would be better. Like this one: http://www.activelivingnow.com/Show...2-1900.htm
Also, if the chair is portable, it may help to move the person into and out of the shower stall. The size and layout of the bathroom may have some dictation. As Craig so eloquently stated, build it and equip it for the intended person. Ask questions about what the person needs and make it accomodate their needs. There are many more thoughts that should go into this. I don't have the building experience, but the plastic seems very expensive as compared to some Krete(sp?) board and tiling. Also, if you do tile, same a few back just in case the valve should ever need to be accessed or replaced. Often, when tiles are made, they make only a certain number and then change the molds. So keeping some back to replace chipped, broken or removed tiles is a wise investment.
Again, if I can be of assistance, please PM me.
