I was trying to fix my toilet and I cracked the bowl. It is on a slab foundation and it drains out the back. It is very expensive to buy a new one and I'm wondering if there is anywhere I can just order the bowl? The model number is K4552.
Thanks!

According to the Kohler web site the K4552 is a discontinued item. The only items available are service parts for the tank, i.e. bolts, valves, etc. I can only suggest you call some local plumbing supply and see what they have or search the internet.

I'm sorry to add: I did a Google hunt and cannot find anyone whose got it in stock.

May I add I did the same thing and came up empty. I'm afraid that you're going to hafta "bite the bullet" and install a new toilet. On a lighter note the old cracked toilet bowl makes a hellava conversion piece as a planter.
Good luck, Tom
