That's an either/or proposition, Dan. You can use a moisture barrier behind the CBU or a direct bonded waterproofing membrane on the face of the CBU, but not both. The areas around a niche are an exception where a trade-off is necessary if you want to use the moisture barrier and still have a niche.

But that same trade-off won't work at the tub/wall joint you have there. You've poked holes in your moisture barrier where you really don't want some and you've got exposed fastener heads that need to be of a corrosion-resistant finish the same as your other CBU fasteners.

Wish you hadn't done that.

My opinion; worth price charged.

I wasn't planning to redguard the whole side just a 6" to 10" strip as previously recommended.

I am open to suggestions. Its not too late to redo or switch things around.

These screws are to lock the tub in place. Its either support the tub and make a hole in the barrier or not support the tub and then just have the CBU screws holes.

The fasteners I can switch to stainless truss heads ones.

As a next step what would you suggest?
1. Switch the screws to SS. Apply a 10" redguard strip.
Or
2. Eliminate the screws. Remove the CBU. Seal the barrier holes with weathering tape.
Or
3. Eliminate the screws. Remove the CBU. Apply new 6 mil poly one the sides overlaping a few inches with the back wall's poly.
Or
4. Start over with new 6 mil poly everywhere and no screws at the flange. The CBU would still be flush or proud of the the flange.

Does RD have "strips"? If so, that. If not, Kerdi.

Hi,

1. 5" Kerdi-Band is ok?

2. Do I apply it only on the sides or continue it to the back wall were the CBU does overhang the flange?

3. Does the CBU gets taped to the ceiling as well?

Thx

A few posts to catch up on the latest progress...

This is how I treated the edge of the bathtub apron. I figured its better to put CBU there as oppose to drywall. Maybe redguard as well?

Drywall is up. I added support for towel racks etc' since they always seems to fall. Also added backing to secure the vanity to.

New sink and toilet supply lines. My first time installing compression valves. Wasn't bad (as long as they stay put ). I'll replace them throughout the entire house now.
The valves are made in Canada, non-plastic stems, and lifetime warranty.

Remaining questions:

1. Is the 5" Kerdi-Band is ok?

2. Do I apply it only on the sides or continue it to the back wall were the CBU does overhang the flange?

3. Does CBU gets taped to the ceiling as well?

Thx!

How do you intend to install escutcheons on those supply pipes?

I found these and figured it would be nice to replace them in a few years if they get gross and rusty. I linked to them in case it helps anyone.

OK, just making sure you were aware that the one-piece ones were not gonna work.

Sorry to nag...

1. 10" or 5" Kerdi-Band for the extra waterproofing by the flange?
link: https://www.johnbridge.com/vbulletin...&postcount=195

2. Apply it only on the side walls (where the flange is flush) or continue it to the back wall were the CBU does overhangs the flange?

3. Does CBU gets taped to the ceiling as well?

Thx!

Dan, the 5" band will be fine, but I think you'll have to cut the plastic away in order to adhere the band to the flange. In on the wall where the backer is almost touching the tub deck I don't think you'll be able to crease the band so you'll just have to let the edge of it touch the deck and then seal it with Kerdi Fix.

Where the backer abuts the apron of the tub - the leg, I'd be tempted to seal that joint with Kerdi Fix, but the little void you have (see pic below) will be a challenge. I'd probably cut a new piece of backer so most of that void is filled, then carefully cut a piece of band to go around the edge of the tub and use KF to seal it.

Yes, tape and mud the CBU where it meets the ceiling.

Thanks for the help. Page 32 (page 17 in previous versions?) of the Schluter shower handbook helped portray the process.

The flange is fairly long (1-1/4") so I think I'll leave some of the poly untrimmed (~1/2") so that it can still serve its purpose and wick moisture into the tub. It will still leave 3/4" for the kerdi-fix to attach to the flange.

If there are no tub flange screw holes in the back-wall's poly why apply kerdi-band there? Since the poly is in tact, is it not "less is more situation..."?

bump to whether you think the kerdi-band should also be applied to the back wall if there are no tub flange screw holes through the poly and the CBU overhangs the flange?

Thx
