curbless shower

[ANGELofDEBT]

John,

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

[jadnashua]

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.

You can see the residue from the setter cleaning his tools in the shower. When we cut out this failed Kerdi Shower we discovered that the PTrap was 3/4 full of mortar.

In the back corner the tile is sloped in a way that it does not drain very well. It is hard to achieve proper grading and meet industry standards in lippage.



With a little care and some more for thought all this Kerdi and all this tile would not make it's way to the dump. Here in Canada our "Tile Council" or "Tile Governing Body" is the TTMAC.

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

Does evaporation ever become a concern with this coin trick?

[johnfrwhipple]

In the summer it is more of a concern and when there is a lot of air movement. This time of year I don't really set up an evaporation control but on a longer flood test with different job site conditions we do monitor and measure it with a separate dish. The coin(s) don't lie and measure the water level very accurately. I never liked the pencil mark because of the oom for error. Did it drop a 1/16"? An 1/8? So hard to tell and if is much easier calling a client and asking if my coin is 50/50 in and out of the water.

Lots of my clients are older as well and they do not want to get down on their hands and knees to check a mark.

I love the 2lb foam. I have a load in my house and still only have 3 rads of 21 running. Incredible that the home stays warm mostly from light bulbs and cooking dinner. We turn on the fireplace which makes the living room toasty for TV time and the lost heat from their heats our bedroom. I'm going to hook up these rads very soon and am getting them lined up in my garage this weekend for painting.

Our latest curbless shower is taking shape here in Vancouver.

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.

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.

[Freddie]

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

Hi freddie. Looks like your renovation questions are on this Thread.

[johnfrwhipple]

Here is a peak at my current barrier free project.

[johnfrwhipple]

If you look at the pile of garbage in this post http://www.terrylove.com/forums/show...l=1#post322362 (Post #33) above you will see the drain and the garbage created by allowing an unskilled builder design and build a barrier free shower.

I could not throw the old drain away and stored it outside my shop all this time. I am going to recycle this drain for my friend and it will be used in the project above. Since the drain was damaged when removing it I have scrapped the factory applied membrane and cut it to size. This of course makes it not a proper drain anymore (The Quick Drain USA products are primary shower drains) so we are using it as a strainer body only and installing over that black ABS clamping drain you see above.

Just to make it harder we are going to light this drain as well with two sets of three RGB LED on each end.

Here are a few pictures of our latest barrier free shower under flood testing here in Vancouver. I filled the shower yesterday at about 11:00 AM.

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.
