Problem being is there is mold and mildew behind the tile. Every time it gets moist it will come back.

Once it gets behind the tile is nearly impossible to get rid of.

But I agree in any situation that has water penetration should be left to fly dry out before moving forward with any fix.

What organics are back there for the mold to feed on? If it's drywall the job won't be around much longer unless there is a water barrier.

What was the existing mildew feeding off of? The organics in the water that was getting behind the tile. Millions of skin cells and other bodily waste. Hygiene products like shampoos and conditioners. If there is that much water there is a ton of organics to feed from.

Since we're discussing how to water proof this joint, I'll throw out an interesting, ongoing issue we have.

So I've already described the way I do the waterproofing. I then tile down and leave an 1/8" gap. We are still using cementious grout and sealing it. Then caulking the corners and tile to tub transition.

On a job we did sometime last winter the client recently told us the caulk was getting soft on the wall the valves are on. My dad went over there and cut out the caulk and water came out from behind it.

He re caulked it, and same issue has happened again. He and I were discussing how grout is permeable and caulk is far less permeable. What's the chances that water is splashing off the client while showering and soaking through the grout joints and then getting stuck at the caulk and not able to flow out?

Or the plumbing could be leaking somehow. Only way we came up with testing it would be to run the shower hitting the back of the tub and see if water comes out of the joint with no caulk in it.

My understand was transition of dissimilar materials are supposed to be caulked and so you would caulk the tub to tile joint.

I'd love to hear anybody's thoughts on this issue...
My gut says check the shower valve and shower head elbow. Take the valve handle and flange off and inspect that area. I just finished a repair job where the shower head elbow leaked when it was turned on......rotted out the whole wall. The house was built 4years ago.

Thanks. We will check that. It happens to be on a rain head with a 10" straight extension coming out of the wall if I remember correctly. Might be leaking from the elbow...

Are we talking mold or mildew?

The space drains, no moisture to support growth.

I agree on the shower elbow.

The valve piping is behind the drywall how would a leak/water there get between the tile and backer? If the leak is on a supply line there would be constant water flow, this should show up elsewhere.

Mold and mildew it doesn't matter. They are both fungi that have similar characteristics.

Only if you find and repair the source of the moisture build up.

Could be leaking at the goose neck. Could also be touching the backer and being wicked in. And it may or may not present itself in other areas. Water likes the path of least resistance.

I had one of my guys install the trim and forget to dope or tape the elbow. I got a call from the landlord a week after the tenant moved in complaining about the water leaking from the mixer. Sure enough it was coming from the goose neck and head elbow, draining between the tile and out the mixer trim ring. A little Teflon and it was good to go.

For years this just had a small leak only when shower was on. It leaked down the wall and in between drywall and solid surface (cultured marble) the telling evidence was a little watermark on the baseboard drywall area. Then after tearing it all out it was under the shower pan. Ontop of the shower pan. Out under the tile floor by several feet.

All due to a slight drip from the shower head elbow (new construction plumber used too short of a pipe from the elbow to the shower head.)

Re: Tile Backer/tub Flange Transition


In the last picture there is a temporary sheet of plywood under the drill on the floor because two feet to the left of it is the door to enter the bathroom (like something out of a cartoon to open the door step in and fall into the crawl space)

Re: Tile Backer/tub Flange Transition


Back to the tub backer flange. It's amazing what a little water can do if you think it's no big deal to not waterproof it right. The tub manufacturer doesn't care what happens to the house so to follow their instructions are kinda weak. Hardie doesn't have clear instructions either. The tile counsel handbook offers more info for areas like that then any other. My personal favorite is how schluter helps in such transition areas. (If it's not obvious I am bias lol)
