question for Kohler cast iron shower base owners
Our shower glass supplier said the Kohler Purist base we're using has a threshold with about 1/16" slope inward. He said they like to see 1/8", so have offered an extra metal strip to put on the threshold. It's a slightly elevated half-round piece that just gives the shower door an extra lip to keep water in. I would prefer to do without it, both to avoid visual clutter and to avoid something that would potentially trap gunk. We have a tile floor, so a little water on the floor won't be a big problem. But I thought I should ask: has anyone with a cast iron shower pan had trouble getting a decent seal using a frameless glass shower door? Do I need the extra threshold strip?
