Bill,
This is so very kind of you to follow up as GardenWeb had a system crash and lost data including my post, see below:

I'm sorry, but right after I replied to your email, we experienced a problem with our servers which resulted in restoring backup files. Unfortunately, all messages posted within a six-hour time frame were lost -- and yours was one of those posts. I know this is frustrating, but there was no other option. I noticed that Bill Vincent posted your picture and is waiting for your reply, so hopefully you'll have answers soon.

Good luck!

Nevertheless, regarding the leak, I have confirmed that it is from the tiles around the tub area and/or where the tub sits over the tiles. What I wanted to do was to cover the tile area around the tub with redgaurd or MAPIE AquaDefense (or anything else you may suggest) and then use river bed pebbles to re-tile over them as I don't want to pull the tiles and tub out. I have cut through the shower area to reach the fiberglass membrane and watertested it by filling it with water and letting it sit there, and confirmed it has no lick. They didn't fiberglass around the tub as tub has no shower but they missed the fact that water can splash from the other side.

Bill, thank you again for posting the pictures as otherwise couldn't follow up. Looking forward to your reply.

Hey Matt-- I'll get to this a little later-- headed to Staceyneil's house right now to do some touch up work, and when I get back, I'll get into this.

Matt, here's the problem I see just from a quick look. I have a feeling that your design, as innovative and beautiful as it is, will be a problem. The reason I say this is because of places like the head of the tub, where the glass is so close to the tub you CAN'T do anything with it. Even at the "foot" of the tub (against the wall), where you have a couple of inches of tubdeck exposed, even if you DO waterproof it, water will get in under the tile and sit there and "ferment". In order for your design to work, you'd either have to slope your deck so that water will drain back into the shower, or you'd have to put some kind of drain system into the deck, and that would be IN ADDITION to waterproofing.

Either way, if you're going to go forward with this, it might stop the leaking, but you'd have to make sure you seal the waterproofing right to the tub itself. You SHOULD also go up the walls a bit-- about 8-10", but I have an idea that can't happen, either being that then you'd have two layers of tile only part way up the wall.

I think no matter what you do, it ought to be considered a temporary fix until this can be torn apart and reworked.... and I mean that entire side of the bathroom. About the only way I see of making this bathroom useable as it is would be to take the glass down at the end of the tub, and extend it from the shower face glass, back to the wall, to completely close the shower off from the tub. Even then, the tiles that would be inside the shower enclosure would have to come off, the substrate be waterproofed, and then be reinstalled, including on the tubskirt (the vertical pieces below the deck).

Bill,

Thank you for your input. I believe as you suggested ultimately we need to seperate ub and shower area that will most probably happen in couple months so we can take a break from our moving activities.

However for the quick interim fix, what product do you suggest e.g. Red Gaurd, AquaDefense etc. I appreciate your input.

Any of those will do. My own preference is for Laticrete's products. In your case, specifically Hydroban. Keep in mind, these are not meant to be finish surfaces, so you might have to touch it up from time to time, and again, make sure you seal the waterproofing to the tub. best way to do that will probably be with a latex bathroom caulking. At this point, we're not going for pretty- just functional.

Thanks a bunch Bill,

I will keep you posted.

All the very best and Happy New Year,
M.
