Read below for more information about what causes dips in tubs and some helpful solutions that will make your bathroom look new again! Drops in bathtubs are widespread because, over time, they weaken the structure around them, causing them to sink into the floor of the tub.

Step to Follow on How to Fix a Dip in a Bathtub

Step One: Determine

First of all, you’ve got to decide whether or not the dip in your bathtub is severe. Then, gather everyone in the house and see what they think. If anyone says it’s crucial that whatever must be done is done right away, you know that the situation is serious.

If not, then it’s probably not a big deal and can wait for a bit. Just make a mental note of it, and be sure to schedule a time in the future when you can fix it right away. If you decide that maybe it should be fixed right away, but other people say to fix it later, you have to agree with the majority.

That’s probably the best way to go about things in life – don’t get your way all the time, because if everyone did everything they wanted whenever they wanted to do it, then life as we know it would be a chaotic mess.

Step Two: Mark the Spot

After you’ve decided that it is serious, mark the spot with a piece of chalk. Make sure to use enough chalk; otherwise, whatever must be done might not fix the problem completely. If there’s still some room left on the wall, make another mark next to it and choose which one looks like it would be easier to fix.

If you think the spot is slightly off-center on the bathtub, mark both where and where you think it should be. This way, if there’s a difference of opinion about how to go about fixing this problem, you can at least agree on which one of the two should be.

If there is no right answer because the spot is in the center or exactly where it should be, then use your judgment to determine which one to mark. Just try not to make a mistake if you made a mistake and marked the wrong side, don’t use it as motivation to rush through fixing the problem.

Step Three: Fill in the Hole

Fill in the hole with spackling paste. Use a dabbing motion when you apply it to don’t have too much paste on any one spot. This will ensure that you can smooth out all of the ridges when applying them to your bathtub and that the patch won’t look bumpy or uneven.

Step Four: Apply Glaze

First of all, remove any spackling paste that remains in the bathtub. If you have any leftover anywhere else, then you can probably leave it be. If you have leftover spackling paste on the walls, then scrub them down with a sponge. Then mix up some satin glaze to match the finish of your bathtub.

Spackling Paste

Apply it liberally all over the spot where there was a dip in the tub to look as good as new. After it dries, you can use your bathtub again! If you’re satisfied with the result, then that’s great. If you think that the extent of damage does not warrant this level of attention or that it will be too obvious to people who come over to visit, whether it’s fixed or not, then don’t do anything.

Removing spackling paste from the bathroom floor is a lot easier than it sounds. Usually, you can wipe it up without a problem, but if you’ve applied a whole bunch of layers of the stuff and your bathtub no longer sits flush against the wall, then you might have to wait until all those layers dry before you can do anything with it.

Step Five: Let It Dry

Allow the bathtub to dry for at least three days before you use it again. You can even leave it longer, depending on how many layers of spackling paste are still there. But if you let it dry overnight, you can always get back to life as usual sooner. You’ll probably notice that some parts of the spot are darker than others.

 Drying Bathtub

The spackling paste was designed to even out the color, but it will always end up looking slightly off if you’re not careful about how much of it gets applied. So, after drying overnight, you might want to sand down those spots that got extra dark with fine-grit sandpaper before applying your spackle.
