Our house has a raised corner shower stall in the downstairs bathroom. Just by doing a quick search and going off of looks, I'm pretty sure it's this model:

Shower stall

The floor in the shower has these stick on leaves that covered the majority of it and in the last couple days started to peel off. I've noticed before that the floor feels soft in places and sometimes almost has the sound of creaking wood in others. My original guess was that maybe the base was even framed with 2x4s and filled between. This is what the base looks/feels like. The blue circle is the drain. The brown lines feel like possible the supports as they are were it'll creak, but has the most strength. The areas between the lines are were the floor feels "squishy"/has some give to it. It was most likely installed in like 2006/2007 when the home was renovated, so now I'm almost guessing it might feel that way over water leaking into the base.. but I'm not sure of anything on it.

Shower base framing?

Originally I thought it was maybe just made to feel soft, but now that the leaves have started to peel off, we see that it appears to have cracked/been cracking before and the owners attempted to patch it with some sort of square white tape? I've marked them in the picture below with the black line around them. I'm not sure that it's leaking and I haven't removed all of the leaves yet to see the rest, but based on the feel and sounds of the base.. I believe there is an issue and I don't know that I trust that tape to be holding out water. What options do I have here to possibly stop any future cracking or water from leaking? Does anyone know why the shower would be making these noises/feel soft, is it accurate to blame water damage? Preferably I'd like to apply some sort of whole-coverage on to the base rather than continuing on with patches here and there.

  • How does the shower feel when you stand in it? Does it feel a little bouncy or like it slightly lowers? – DMoore Jan 11 '16 at 15:24
  • The three "supports" feel in place for the most part, possibly slightly lowering wherever you step but also making that creaking sound. The best way to describe them would be like a 2x4 that's rotted - it's held up on the edges, but the center has a little give to it and feels like it could crack through. As for the in-between squishy parts, they feel bouncy I would say. Almost like a strong sponge. – TFK Jan 11 '16 at 15:59

    The cracks happened because the lack of base. These usually get installed on plywood plus a mortar bed. If you forget the mortar the cheap bases will crack. So what you can do now is try to keep patching this with epoxy sprays or whatever and it will eventually crack again or you have to remove base and install right... I would see if HD just sells the base. – DMoore Jan 11 '16 at 16:59
  • I agree most are installed with out the reccomended base if it moves it will crack. – Ed Beal Jan 11 '16 at 17:21

    It's not possible to replace the base without taking almost all of it apart though? HD doesn't sell the base, but I see that Delta will sell it for like $350. Might as well save up and get a new shower at that cost. I see in it's reviews on HD that apparently the base is made with some sort of foam under a thin layer of plastic, which has earned it a bad reputation of constantly cracking. I'm not the original owner, but I'm going to call and see if anything can be done by Delta. – TFK Jan 11 '16 at 17:40

I went to my local hardware store and tried to find some options. I originally attempted an epoxy coat, but it did like was mentioned and quickly came loose and fell off because of the flexible base underneath. I then went back to try something else. I saw this stand for "Fiber Fix" and they had one called 'Rigid Patch' which goes on soft and hardens "like steel" in UV light in about 10 minutes. Completely waterproof and shown to patch canoes, wheelbarrows, water tanks, etc. I figured it was one of those typical as seen on TV items, but it was on sell and cheap so I figured it was worth trying if it did what it says it can.

They come in a black pouch with a clear film on it. They provide gloves and sandpaper as well for working with it. It's almost like a fabric when you get it out and is black on one side and gold on the other. The black side is what sticks and the gold fades away to clear when it's dry. You basically place it down on a dry, clean surface and then almost like massage it on from the edges in. The bottom black is gooey feeling and so is the gold underneath of the clear plastic. You try to smooth it on so that there aren't any air bubbles and get a complete seal around the outside. Let it sit in the sun for 10-15 minutes (or UV light in general) and it'll harden and the gold will disappear when it's done. I also noticed that it gets slightly hot itself while drying. My frosted shower door is between the base and the nearest window and this window isn't on the sunny side of the house, but it was still done in about that 10 minute time. After it's dry, you peel up the clear plastic from it and it's good to go. It feels like a fabric when putting it on, but is smooth like plastic when done. It completely sealed on around the edges, covered the holes, and actually has attached itself so tightly to the base that it doesn't really have any give where I placed the two patches.

To finish it off, I coated most of the shower base in Flex Seal. I'd never used it either and wasn't sure about it, but it also seems to work great. It does give more of a rubbery feel to everything and it takes a day to cure, but it seems like it worked.

  • I've got exactly the same issue with my shower, which looks just like the one in the photo above. I've just come across "Flex Seal" - would you still recommend it? I thought about covering the entire floor of the shower. Best, Steve Sloane. – Stephen Sloane Aug 17 '18 at 0:10
