Our framed corner shower is leaking at the "seam." At the corner where the two sides meet, the panels seems to be loose. Whenever I spray water on the glass and framed walls, some water will leak at the corner of the walls.

We are not sure how to "take apart" (if necessary) the walls in order to caulk the corner. Not sure if that is the correct process either. We have called the installer, he is not returning our calls. Surprise, surprise.

Note: water may be coming from where alumininum frame meets the solid surface ledge on top of garden tub. Water collects in weeping holes in the inside and may be coming out on the outside. Here are some pictures. I have taped two areas. Between the two "horizontal" tape pieces the side and the front seem a bit "loose." The taped area pointing at each other is the "seam" where I believe the water is coming from.

The frame is made of aluminum. The shower is standard glass with rubber between glass and frame. The shower is placed against tile walls. Top of ledge above garden tub is solid surface material. Something like "corian." Unsure exactly what it is made from. full view front seamoutside corner viewinside wall 1inside wall 2from top-corner

    A few photos might be helpful. – Tester101 Feb 25 '15 at 15:51

    If the walls are wobbling then it is more than caulk. – DMoore Feb 25 '15 at 15:54
  • I will provide the photos asap. Thanks. I fear this is happening because it is a fairly new home and it may be due to "settling." It was built in the fall of 2012 and we purchased it in summer of 2013. – LuAnn Feb 25 '15 at 17:04
  • We definitely need photos. Also a description of the shower materials would help as well (solid surface, panels, tile?) – DA01 Feb 25 '15 at 17:16

well, short of dismantling the frame and welding the tubes shut (WTF????), you might try an easier approach. never seal the vertical tubes shut. if you have water building up inside the tubes, you need larger vent holes on the bottom of the wet side of the shower. its common that they get plugged up over time.

having assembled dozens of these units over the years, i must admit that the one you have is a little different on the top corner detail, but they are all pretty much the same. the wall has rails mounted to it, then decorative rails slide over those to provide the wall anchor points for the glass. then the corner rail (either stop or hinge) is held captive by the top and bottom channels, which also hold the fixed glass panels captive. the door then hinges off the corner rail typically. since the left and right panels are joined at the corner, this joint tends to flex in two directions and causes the usually inadequate factory seal to fail prematurely.

so, try this (the worst you will do is make it such that if you do have to disassemble the unit, you might have to scrape out some caulking) after you have left the unit to dry for a few days (you can use a hair dryer to speed up the process if need be):

1) clean all surfaces that you are going to seal really well with methyl hydrate or methanol. any places that have been previously siliconed over will have to be scraped clean and then cleaned with silicone sealant remover.

2) get a renovators bar (or 10) or a butter knife (or 10) and slip them in the joint to wedge the offending corner joint apart. just a little, just enough to get the sealant in. then get yourself a large bore (14 ga or larger for silicone) hypodermic needle (like the kind to refill ink cartridges with) and inject clear silicone (NOT LATEX) sealant into the gap. go slow and inject way more than seems reasonable (the metal extrusions often have convoluted profiles that are invisible from outside the joint that will allow for the silicone to not seal well). go from top to bottom and tap the frame often to get the silicone to settle and cling to the inside of the joint.

3) on the wet side of the shower, and only the wet side, run a vertical bead of silicone over the joint. i would mask the joint with tape so that you can get a nice bead with little mess.

if you do all the cleaning well and be very thorough, this will solve your leak. you may have to do it again every couple of years, but it generally works permanently.

The shower frame is a hollow tube. Water gets inside of the tube and leaks out at the ends of the tube. If the tube has weep holes they are most likely to high to do any good or stopped up from soap scum. The best solution is to take the frame apart and weld ends on the bottom aluminum tubes this will seal the ends of the tubes and force the water to exit out of the weep holes. Welding the ends will discolor the finish. That can be touched up with a can of spray paint. A lot less expensive then replacing subfloor and tile or even framing. Another method would be to dismantle the frame and fill the bottom channels with silicone caulking.The draw back to this is the caulk will most likely mildew in time.
