Do these two play well together?

Don't need the preslope for the Kerdi system, but if you need to smooth floor you could. :)

Hi Rob,
You can't use the proslope under Kerdi for your basic slope because Kerdi really needs the Kerdi drain, & the Kerdi drain won't fit right into the Pro Slope I believe. Here is a link (http://www.tile-experts.com/products.asp?id=53) to a preformed slope made to go with the Kerdi system. I've haven't tried it myself, I prefer mud. :)

Okay, I realize that was a dumb question. :crazy:

After looking at the materials and some of the videos, my biggest concern about the system is how I would attach the drain. I'm currently on a slab with a cast iron drain. After tearing down my shower and removing the old mud pan down to the slab, will I likely have to dig out concrete surrounding my current drain to attach the new drain? This part wasn't clear in the Kerdi system materials.

Hi Rob,
Yup. A roto hammer with a chisel head makes quick work of chipping out the concrete. If you don't want to do that you can reuse your old drain (if it's still in good condition) & do a regular old fashioned mud pan with a mud preslope, then liner, then a mud final bed. You can still use Kerdi for the walls.

Rob,

I would go for the complete Kerdi system. Dig out the old and install the new. :)

John that's just not fair tempting him with that brand new beautiful clean drain that's rustproof. Now why would he want to take a chance on another 30 years with the old cast iron? :D

I would go with the complete Kerdi system as well. It'll save you time you didn't know you'd have to spend otherwise doing a conventional shower.

The new Kerdi-drain video deals with attaching to pipes that are already in place. The old video showed an installation where one had access to the plumbing from below.

I'll have to check when the video will be out - I'll keep everyone posted.

That says a lot when people tell you that hammering out concrete will be easier than putting in a traditional pan. The updated video will be nice to see. What kind of installation instructions come with the shower kit?

There's an installation CD included in every drain box. If you'd rather have VHS format, that's still available. I'm not sure how long the new one is, but I'd put a guess at 40-45 minutes. The older one, if memory serves me correctly, is 30 minutes.

"The Making of the Kerdi-Drain Video" comes in a special collectible 2-CD case and includes out-takes and alternate endings. Candid interviews with the cast of the video are a highlight of this bonus CD.

Ok... so there's no bonus CD. I was joking about that part. :D

It would still be far better than the Showgirls collector dvd.

My tiling book must be on the slow boat. I still haven't received it yet. I'm anxious to start reading.

Hi Rob,

I'm not sure how long the book takes to travel to Hawaii. It's usually four or five days on the continent. They may have had Cliff Claven tie it to a driftwood raft and send it out with the tide. ;)

Media mail to Hawaii can take up to 3 weeks. Priority is usually 4 days. It's okay. I'm still doing my Kerdi research on this site.

Still worried about chipping around that drain. Never done that before. I'm trying to get everything prepped in advance, but I'm sure I'll discover a lot more after I demo the shower.
