    I did not look up the pictures but will find some now for you.

    Can we agree that for now - the Kerdi Foam Curb looks like someone used a tool box as a shower curb and then tiled it.
    2" above top of shower drain, a standard code for US?

    For example if you search curbless shower codes you will find dozens and dozens of references to the John Bridge members talking about a 2" drop. This code is from the IRC and affects only a few states. The UBC and UPC are followed by many and these code books have been updated.

    Are you following more lame ass John Bridge Forum advice sighting the IRC or are you reading something from an updated UBC book?
    This is from our county website, page 3
    Section 417.5 Shower floors or receptors; amended to read as follows:

    Floor surfaces shall be constructed of impervious, noncorrosive, nonabsorbent and waterproof materials.

    Thresholds shall be a minimum of 2 inches (51 mm) and a maximum of 9 inches (229 mm), measured from top of the drain to top of threshold or dam. Thresholds shall be of sufficient width to accommodate a minimum twenty-two (22) inch (559 mm) door.

    Exception: Showers designed to comply with ICC/ANSI A117.1.

    Thanks John,

    I'm not so concerned with having a curbless shower as I am with getting a lower than 6" kerdi curb. So what I will do, is use the kerdi pre sloped pan and use bricks instead of the foam curb. I will look into getting a solid curb top instead of tiling the top of curb; and then try to set to the minimum height of 2".

    the pan is about 1 1/2" thick around the perimeter; so after tile and with the thickness of the solid curb top, I think the outside height of the curb could be closer to 4".

    Also, I think that by using a solid curb top, if it overhangs a little bit, it will make the curb as a whole look less "boxy" and more aesthetically appealing.

    Leo

    Why it shouldn't be in wood -- the curb -- John ? Since you do residential work -- no metal studs involved -- all your blockings , studs , subfloor , etc. is in wood . What changes for the curb ?

    Other than -- no penetrations allowed -- through the curb , which is one of the most important advice found on -- John Bridge Forum -- the wood will survive if the building process is respected as per the walls . CBU's over it , membrane and the rest .....

    Even your steam showers are build over wood frame ...... don't know where you got the idea of no wood for the curb allowed is not a good one .

    I'm with Roberto.

    Wood as a substructure for a curb, properly installed and water-proofed over a wood framed floor, is a fine installation. And has been for many decades throughout north America.

    Wood as a substructure for a curb, installed over a concrete or gypsum floor is not such a good idea. In these cases, a more dimensionally stable non-wood substructure should be used.
