How an "old" method shower pan floor is supposed to be built. Note the mandatory slope UNDER ______the membrane. (blue) A surface membrane such as KERDI eliminates this problem. I've included this sketch so all you plumbers & tile guys will see how a "standard" shower is supossed to be built. You licensed plumbers already know. SO, WHY don't you every build showers correctly? Homeowners: Your present shower was most likely built without the pre-slope under the membrane. I GUARANTEE IT. This means that as you use the shower the small amount of water that gets through the tile work is trapped by the membrane and can NOT escape the system through the weep holes because the membrane is flat on the subfloor. If done properly as above, the excess shower water would find its way to the weep holes built into the drain. I have replaced several dozen shower floors, I have yet to find one that was built correctly. That is one reason I now ONLY BUILD KERDI showers.
A typical shower when there is no waterproofing behind the tiles. Remember, tiles do not make a shower waterproof. This shower was less than 20 years old when it was demod & re-built. There was little evidence of the condition before it was removed, just some discoloration of the grout at the bottom.
No...... it's not trick photography. Be careful or you might end up with something like this. The tile guy said he had lots of experience and offered the cheapest prices.
What the heck is that?
Oh boy! Another handyman here.
The customer hired a family friend who installed both the tile and hardwood. YIKES!
He actually left it like that.
A handyman the customer found on Craigslist cheap! I wonder how cheap it'll be after it's all ripped out and redone the right way.
How NOT to build a shower. This foto was sent to me by a resident in Oakland County whose tile contractor was still on the job finishing this shower. (Jan. 2011). She was concerned about the "sloppy" work of the tiling and grout. She only had this foto taken a week before, showing the prep done and how the membrane was installed. (All wrong, by the way.)
She thought she had hired a professional since this general contracting co. is licensed & with all documentation, was one of two referred to her by The "S_ _ _ _ _ _ Magic" Company.
I advised her this shower is NOT waterproof and was built contrary to directions and should be ripped out and redone correctly. No word yet. I think she's embarrassed to go much further with her complaints. Too bad.
