Hey Chris,
You are correct, all the wedi shower kits only come with one curb. The curbs are also the “lean curb” which is 2″ wide and 3 1/2″ tall.
This works will if you plan to use a 4″ curb top (marble/travertine/etc) but if tiling, may be a bit small and difficult to center the glass surround on.
The other curb type is the full curb. which is 4 1/2″ wide x 5″ tall. A 6 1/2″ curb top works well with this, or simply tiling it as well
You may want to consider buying all the components separately.
You can buy the pan, wall board, curbs and sealant all separately
A great online site for this is http://www.masterwholesale.com
Whats the size of shower and height of room? I can help or double check what you plan to buy.
