John Whipple - By Any Design ltd. Rick I'm finding that sometimes a linear drain does not help with these barrier free shower designs. What key is having the right grade to the shower and some safety designed in of water gets past the door.
In many showers the weakest point is when the hand held spray hits a shower door with no divertor. When this happens the water goes in both directions and this can cause a large amount of water to escape the shower.
Better design would include a secondary drain - somewhere outside the shower and before the door to the bedroom or hall. We are grading and building our barrier free showers larger than the wet zone so we can have this safety incorporated.
The ADA guidelines allow for no more than a 1/2" step or lip. Using a 1/4" lip as a minin dam can do wonders for a shower's function. We did just this on our last install and could remove the door sweep and keep the glass 5/8" off of the floor so my client can use a bathmat. The floors outside these curbless showers can be slick if the wrong tile is used and there is little grout joints.
Rick Clarke Design Good news John. Nice to hear that you have GOT this figured out. Your attention to the details is obvious. Such an expensive route to go and we have done many as well. Almost each one has been custom designed to suite each client. I have learned NOT to assume the "tile setter knows best".
Rick Clarke Design The space for a toilet by code is 30` 36 is much better if it`s possible. If the TP holder has to be mounted on the side of the cabinet then wider is better so that you don`t put your body out of wack trying to get at the TP.
