In that location are a few options when information technology comes to how to repair a croaky shower pan. If you don't know your options or exercise your research, you'll be throwing money down the bleed (pun not intended).
There 2 of import things you lot demand to find out first:

i. What caused the crack? (i.due east. Did something heavy dropped/fell? Is information technology from regular use? Are they stress cracks?, etc.)

This data yous would need to provide to your bathtub refinish specialist. How it cracked may determine the best option for repairing the cleaved surface.

2. Does the surface area surrounding the crack flexing? If you apply weight to the area, does information technology bend, bow or give?

No flex? EXCELLENT!! There is a very practiced take a chance this crevice tin exist easily fixed.

If the expanse flexes nether pressure level, your shower pan doesn't have the proper support underneath it. You would be shocked as to how many shower pans lack some, if non all, support when they were installed during construction. Now, there is a possibility that the shower pan can be salvaged  (by adding support) if the flexing area is approximately 1 foot in diameter. How is this done? The specialist will drill a pigsty (possibly even multiple holes) into the unsupported area or cutting the area out, and then utilise a high density support foam. This support product will demand to be special ordered. Avert using the support foam you can find at a local general store. Those products will non agree applied weight for an extended period of time. The holes/cut out will then exist filled with a h2o-proof filler and sanded affluent. The whole area is then cleaned and prepped. The urethane acrylic color is matched to the existing color of the shower pan and sprayed in the needed areas or the whole shower pan can fully refinished; whichever is needed. TA-DA! (Y'all may demand to leave that surface solitary for 1-3 days depending on the loftier density foam cure time.)

Now in our experience, if the flexing area is larger than a foot, replacing the shower bowl is usually the best option.  You can still TRY to have a specialist repair it, but it may but be putting a band-aid on a broken leg. High density support foam will simply do so much. Replacing may be your best/only choice. Talk to a specialist, get an adept stance, but exist cautious. An honest bathtub refinish specialist will permit you know is the salvage is worth pursuing. Don't be taken advantage of. Practise your research. Feel free to contact united states if you have any questions.

This shower pan crevice was acquired by standing weight. The lack of support underneath caused the shower bowl to give when someone would stand in it.IMG_0261
