Why Does My Tub Have a Dip in It?

The most common cause of a dip in a bathtub is structural damage. This can happen from water that has been allowed to seep into the base of the tub, which causes weakening and deterioration in the flooring beneath it. It could also be caused by something heavy being dropped on the surface of the tub or even poor installation when first putting it in the tub. In any case, you’ll need to identify what exactly is causing the dip before you start attempting repairs.

If your issue seems to be related to water seeping through and weakening the underlying structure, look for any places where water might have had an opportunity to get underneath or around the bathtub — cracks around tile grout lines or loose caulking, for example. If you find any of these issues, you’ll need to repair them before beginning the dip repair process.

If your bathtub’s dip is due to something heavy being dropped on its surface or poor installation, you may want to contact a professional or licensed contractor who specializes in tub and plumbing repairs. They will be able to provide you with advice and assistance on how best to repair it, as well as ways to prevent future problems from happening.  After all, prevention is always better than cure – and it can save you time and money in the long run!

Additionally, if there are any underlying structural issues that could have caused the dip, like rot or mold growth due to water damage over time, it would be wise to get these problems taken care of by a professional as soon as possible. This can help you prevent any major damage or deterioration in the future, making sure your tub remains safe and functional for many years to come.

7 Methods How to Fix a Dip in a Bathtub

1. Use a Plunger

If you have a plunger, you can try using it to fix a dip in your bathtub. Plungers work by creating suction that can help to push the water back up and into the tub. To use a plunger, simply place it over the drain and push and pull it up and down. If the dip is too small, you may need to use a cloth or rag to tie around the plunger and create a seal. Repeat this process several times, and you should see the dip start to fill up.

2. Use a Wire Hanger

If you don’t have a plunger, you can try using a wire hanger to fix a dip in your bathtub. To do this, unwind the wire hanger, so you have a long piece of wire to work with. Gently insert the wire into the drain and move it around to dislodge any debris that may be causing the dip.

After a few minutes, remove the wire and run water down the drain to check if the dip has been removed. If not, repeat this process until you have successfully fixed the dip. However, be careful not to scratch the surface of the tub when using a wire hanger.

3. Use Boiling Water

Another way to fix a dip in your bathtub is to use boiling water. Boiling water can help to break up any clogs that may be causing the dip in your bathtub. To do this, fill a pot with boiling water and pour it over the affected area of the tub. If you don’t have a pot, you can also use a bucket or container.

Make sure to spread the boiling water evenly over the dip in order to break up any clogs that may be causing it. Leave the boiling water on the dip for about 10 minutes before draining it out. This should help to get rid of any pockets of air that may have been causing the dip. Once you have drained out all the boiling water, run your hands over the affected area to make sure that it is even and smooth.

4. Use Vinegar and Baking Soda

Vinegar and baking soda are other effective ways to fix a dip in your bathtub. Pour a generous amount of white vinegar into a spray bottle and coat the dip with it. Wait for five minutes, then sprinkle baking soda over the vinegar-soaked area. Let this sit for five minutes, then spray it again with more vinegar.

Wait 10 minutes before rinsing away the mixture. This combination will help to fill in small holes and cracks. After the area is dry, wipe it down with a damp cloth. Applying a sealant over the treated area will help to protect and extend the life of your bathtub.

5. Use Dish Soap

Dish soap can also be used to fix a dip in your bathtub. Simply fill the dip with water and then add a few drops of dish soap. You should use a small brush to mix the water and soap together in order to make sure that it is distributed properly throughout the dip.

After a few minutes, you can drain the water from the tub and then let it sit for 24 hours before applying caulk or putty to the area. This will help create a seal around the dip and prevent further damage from occurring. Although it may not be a permanent fix, it’s an easy and inexpensive way to temporarily solve the problem.

6. Use Salt

Salt is another common household item that can be used to fix a dip in your bathtub. To use salt to fill in the dip, you’ll need a few tablespoons of plain table salt. Sprinkle the salt onto the dip and then wet it down with a little water. Using a damp cloth or sponge, scrub the area for several minutes.

The salt will act as an abrasive to help break up any debris that may be blocking the dip. After scrubbing, rinse the area with a damp cloth and then add another layer of salt to the dip. Allow this to sit for about 30 minutes before rinsing it off again. The salt will help fill in any remaining dips, leaving your bathtub looking like new!

7. Use an Epoxy Compound

If all else fails, you can always use an epoxy compound to fix a dip in your bathtub. Epoxy compounds are specially designed for this purpose and provide a strong, long-lasting seal that will last for years.

Start by sanding down the area around the dip and then cleaning it of all dirt and debris. Once clean, apply the epoxy compound according to the package instructions. Allow it to cure for at least 24 hours before using your tub again. This is a permanent solution that will fix even the deepest dip in your bathtub. With proper care and maintenance, your tub should look like new again.

No matter which method you choose, fixing a dip in your bathtub is relatively easy if you have the right materials and tools on hand. As always, be sure to check with a professional or licensed contractor if any underlying structural issues need to be taken care of before attempting any repairs yourself. To ensure your tub remains safe and functional for years to come, it’s best not to take any chances!

Things to Consider When Fixing a Dip in a Bathtub

Before attempting to repair a dip in your tub, it is important to assess the extent of the damage. Rather than trying to make a quick fix, it is best to determine the source of the dip and assess how long it may take to repair. The depth of the dip is also a factor when considering repair options.

1. Application of a Patch: 

If the dip is shallow and not too large, you can try patching it with epoxy or concrete repair products. These materials are designed to fill cracks and dips, matching the color and texture of your tub’s surface. To patch the dip, start by cleaning the area with a cleaner and a scrub brush to remove any dirt or grime. After it’s dry, apply the patch product according to the package directions. Once it’s dry, you should have a repaired tub surface with no more dip.

2. Replacing the Tub:

If the dip is deep or large enough to warrant a replacement, you will need to purchase and install a new bathtub. This is time-consuming and expensive, but it often provides the best results and can make your tub look brand new again.

3. Professional Help:

If you are unsure of how to repair the dip or don’t have the time or resources to replace the tub, it may be best to hire a professional contractor who has experience dealing with this type of problem. They will be able to assess the extent of damage accurately and suggest appropriate repairs.

4. Safety Considerations:

Regardless of which repair option you choose, safety should always be at the forefront of your mind when working around a bathtub. Make sure that any repair products you use are rated for use in bathrooms and that the area is well-ventilated. It is also important to wear protective gear such as gloves and a face mask when handling any chemical-based repair materials.

By keeping these things in mind, you can ensure that your bathtub dip repair project goes smoothly and results in a durable fix.  With proper care and maintenance, you should be able to keep your tub looking beautiful for many years to come.

Can You Patch up a Bathtub?

Yes, you can patch up a bathtub. There are several types of kits available for patching up a bathtub and fixing small chips or cracks. The most common kits contain epoxy putty or resin that is applied to fill in the damaged area. After the putty or resin has dried, it is sanded down so that it is flush with the surface of the bathtub.

If you have a more significant dip in your bathtub, the best option is to use a flex sealer kit. This type of kit involves applying a flexible sealant that dries quickly and forms an airtight barrier around the affected area. In some cases, you may also need to use a bit of putty or resin before applying the sealant to make sure that the dip has been properly filled in.

No matter what repair kit you choose, make sure to follow the manufacturer’s instructions carefully for optimal results. Additionally, consider consulting a professional if your bathtub has sustained more serious damage. A professional can help provide a more permanent solution and ensure that the dip won’t reappear in the future. With proper care and maintenance, your bathtub should be looking good as new in no time.

Consider Consulting a Professional
