    Not being a person in the business or done a linear drain before, can you point out what is the problem with the shower?

    You want the water to drain into the drain! It appears that water would tend to pool between the wall and the drain, assuming the slope is from the main area into the drain. It could get there by splashes or directly from the showerhead. You'd either need to reverse the slope on the wall side to the drain, or move the drain next to the wall. Then, it's best if the drain is the full width, as you might get the same pooling at either end.

    Nice to see the 2lb. spray foam in a few of your pictures John.

    Does evaporation ever become a concern with this coin trick?

    John, Another gorgeous shower. We are looking into the very same setup for our ensuite reno. Corner glass walled curbless shower and freestanding tub exactly as you show it. Am struggling as to how to make this possible. I've attached a picture of the half torn out bathroom. Name:  Ensuite Bathroom Reno 009.jpg

    Can this be done without a curb and without cutting the joists? I'm in Ontario if that helps.

    thanks,

    Unless you can raise the entire floor, to construct the shower pan, it MUST slope from the entrance to the drain, and since that needs some thickness, it has to come from somewhere.

    Assuming that I dropped the floor down the thickness of the floor which is 5/8" OSB and then added the drain and 3/8" for slope change ( 3' x 3' shower, drain in center). So say top of lowered floor to top of drain would be 1.25". Then add 3/8" for slope and you are at 1 5/8" from lowered floor or 1" above the floor of the remainder of the bathroom. This would be for no curbs at all.

    Alternatively, I guess I could put a full 3' linear drain at the front of the shower at the door at the level of the finished bathroom flooring and slope the shower up 3/4" (3' x 1/4") to the back of the shower and add a curb to the left side of the shower. Would then have a curbless "entry" at least.

    Do you think these 2 approaches would work and do my numbers seem correct?
    Just looking at what each option would require in terms of changes to current bathroom and comprises. Current bathroom tile has all been taken up so that's not a deciding factor. Current bathroom had 1/4" plwood

    Well finally back from NYC, totally enjoy that city. Now back to this bathroom reno. As I have not done one of these linear drains before, I've having a hard time figuring out the amount of space I need from the lowered floor to the top of the linear drain. None of the websites that I've looked at show that dimension. They do show some support below the drain but usually it is something supplied but no dimension on it. Can anyone give me some idea on thicknesses of items, so that I can best determine how and if I can make this work? I know there is paper (1/16"), wire mesh (1/8"), mortar#1 (??"), membrane (40 mil), mortar#2 (??"), thinset (1/8"), tile (1/4"). I assume mortar #1 and mortar#2 has a minimum thickness based on drain requirements but have no idea what that would be. Just looking for some guidance.

    As an option, would less space be needed if I went with a standard center drain in shower rather than the linear drain?

    We've got most of the fixtures and tub finalized so this is the last portion before we select tile.
