Advisable to use Schluter Kerdi Shower Curb if not using their shower tray?

[mindyrella]

I am getting ready to remove a fiberglass shower and replace with a tiled pan and walls by Kohler Choreograph. My dad is a retired builder and is going to help me execute the project. However, neither of us have constructed a shower pan before so I am trying to gather the required materials that will make this as easy as possible and make the shower as waterproof as possible. I noticed a ready-made curb available on Amazon by Schluter Kerdi, but the product description says it is designed for use with Schluter shower tray. However, because my shower is not typical dimensions, I cannot use any of their trays and will be pouring/forming the shower pan. Is it advisable to pair a custom formed shower pan with this Schluter curb? Any advice on this is greatly appreciated.

you can use the kerdi curb then mud the floor using kerdi drain apply kerdi to top of mud and overlap curb. I cant think of any way the kerdi curb could be used with a traditional liner

If you're in a pinch and need to get the curb set quickly, the Kerdi curb will work just fine, provided you can get your hands on it quickly. However, if you're over a wood subfloor, a stack of three 2x4's with sheetrock over it will work just fine and is cheaper.

If you're working over a slab, you can make the curb out of brick, block, or any other cementitious product. I usually form up and pour concrete for mine, but I have no problem waiting for it set up overnight.
