Can You Cut A Cast Iron Tub With A Sawzall

The short answer is yes, you can cut a cast iron tub with a sawzall. In fact, it’s one of the easiest and most versatile tools for this type of cutting. Reciprocating saw blades are available up to nearly a foot in length, making it easy to cut through most anything.

However, it’s important to note that cutting through a cast iron tub can be a messy and potentially dangerous process. You’ll need to take proper safety precautions and follow the steps carefully to avoid damaging your plumbing or injuring yourself.

Safety First: Preparing For The Job

Before you start cutting your cast iron tub with a sawzall, it’s important to prepare for the job properly. Here are some safety precautions to take:

1. Wear protective gear: Cutting through cast iron can produce a lot of dust, sparks, and debris. Make sure to wear protective gear such as safety goggles, a dust mask, and heavy-duty gloves.

2. Turn off the water supply: Before you start cutting, turn off the water supply to the tub and open the faucet to drain any remaining water in the supply lines.

3. Disconnect the drain pipe: Use needle-nose pliers or a drain flange removal tool to loosen and disconnect the drain pipe from the tub.

4. Cut away from the wall: Unless you have a freestanding tub, you’ll need to cut through the wall above the tub to remove it. Carefully cut through the wall 6 inches or less above the tub with a reciprocating saw, making sure not to cut any studs, wiring, or plumbing inside the wall.

5. Protect your support structure: If you’re using a sledgehammer, be careful not to damage your support structure. A demolition hammer may be a safer option.

6. Set up a work area: If you plan to break the old tub into pieces, set up a work area by laying down plywood. Have a friend help you pull the heavy cast iron tub away from the wall and set it on the plywood.

By following these safety precautions, you can ensure that your cast iron tub removal goes smoothly and safely. Remember to take your time and be careful throughout the process.

Choosing The Right Blade For Cutting Cast Iron

When it comes to cutting through cast iron, choosing the right blade is crucial for successful and efficient results. There are a few different types of blades that can be used, each with its own advantages and disadvantages.

One option is a diamond blade, which is specifically designed to handle tough materials like cast iron. These blades are durable and can make quick work of even the thickest cast iron tubs. However, they can be expensive and may not be necessary for all projects.

Another option is a carbide-tipped blade, which is less expensive than diamond blades but still able to handle most cast iron cutting projects. These blades are not as durable as diamond blades and may need to be replaced more frequently.

Abrasive cutoff wheels are also an option for cutting cast iron. These wheels are less expensive than either carbide-tipped or diamond blades but are also less durable and won’t last as long. They’re a good choice for smaller projects or if you’re on a budget.

It’s important to choose a blade that will work best for your particular project. Consider the thickness of the cast iron tub, the size of the blade you need, and your budget when making your decision. Always wear proper safety gear, including eye and ear protection, when cutting through cast iron with a sawzall.

Marking And Measuring: Prepping The Tub For Cutting

Before you start cutting your cast iron tub with a sawzall, you need to properly prep the tub. This involves marking and measuring the area you want to cut.

First, mark the area you want to cut with a permanent marker. Make sure to be as precise as possible, as any mistakes can lead to uneven cuts or damage to the tub. Measure the length and width of the area you marked to ensure that your sawzall blade is long enough to make the cut.

Next, use a level to draw a straight line across the marked area. This will guide your sawzall blade and ensure that your cut is straight and even.

It’s also important to protect the surrounding area from flying debris. Use drop cloths or old towels to cover any nearby fixtures or surfaces that could be damaged by debris.

Once you have marked and measured the area and taken proper safety precautions, you’re ready to start cutting your cast iron tub with a sawzall. Remember to work slowly and carefully, and always wear appropriate safety gear such as gloves and eye protection.

Cutting The Tub: Techniques For Success

Cutting a cast iron tub with a sawzall requires some technique and patience. Here are some tips to ensure success:

1. Choose the right blade: The key to cutting through cast iron is using the right blade. Look for a blade specifically designed for cutting through metal, with a high TPI (teeth per inch) count. A carbide or diamond grit blade can also be effective.

2. Mark your cuts: Before you start cutting, use a marker to clearly mark the areas you want to cut. This will help guide your sawzall and ensure that you make clean, straight cuts.

3. Secure the tub: Make sure the tub is securely in place before you start cutting. You don’t want it to move or shift while you’re working, as this could cause damage to your plumbing or injury to yourself.

4. Start with small cuts: Begin by making small cuts across the width of the tub, dividing it into thirds. This will make it easier to handle and give you more control over the sawzall.

5. Take breaks: Cutting through cast iron can be tough work, so take breaks as needed to rest your arms and hands. This will also give the blade time to cool down and prevent it from overheating.

6. Wear protective gear: Always wear eye protection, gloves, and a dust mask when cutting through cast iron. The process can create a lot of dust and debris, which can be harmful if inhaled.

7. Clean up carefully: Once you’ve finished cutting, clean up any debris and dust carefully to avoid damaging your plumbing or injuring yourself.

By following these techniques, you can successfully cut a cast iron tub with a sawzall. Just remember to take your time, use the right blade, and prioritize safety at all times.

Removing The Cut Tub: Tips And Tricks

Once you’ve successfully cut the cast iron tub into smaller pieces, you’ll need to remove them from your bathroom. Here are some tips and tricks to make the removal process easier and safer:

1. Wear protective gear: Before handling any of the broken pieces, make sure to put on gloves, safety glasses, and a dust mask. This will protect you from sharp edges and flying debris.

2. Use a sledgehammer: While a sawzall is great for cutting the tub, a sledgehammer is the best tool for breaking it down into smaller pieces. Start by making two cuts across the width of the tub to divide it into thirds. Then, use the sledgehammer to break each section into smaller pieces.

3. Score the surface: Some professionals recommend scoring the cast iron tub with an angle grinder before using the sledgehammer. This will help you control where the tub breaks and reduce the amount of force needed to break it apart.

4. Be mindful of plumbing: Make sure to avoid cutting through any plumbing or electrical wires while using the sawzall or sledgehammer. It’s a good idea to turn off the water supply and disconnect any pipes before starting the removal process.

5. Remove by hand: Once the tub has been broken down into small enough pieces, carefully remove them by hand and place them in buckets or bags. Cast iron is heavy, so be prepared for a workout!

By following these tips and tricks, you can safely and efficiently remove a cast iron tub that has been cut with a sawzall. Remember to take your time and prioritize safety throughout the entire process.

Cleaning Up: Post-Cut Maintenance And Disposal

After successfully cutting through a cast iron tub with a sawzall, it’s important to properly clean up and dispose of the debris. First, make sure to wear gloves and protective clothing when handling the cut pieces, as they may have sharp edges.

To clean up any remaining metal shavings or dust, use a broom and dustpan or a vacuum with a HEPA filter. Avoid using water, as it can cause the metal shavings to rust and potentially damage your plumbing.

When disposing of the cut pieces, check with your local waste management facility to see if they accept cast iron tubs. If they do not, you may need to hire a professional junk removal service to properly dispose of the debris.

It’s important to note that cutting a cast iron tub into smaller pieces may make it easier to remove from your bathroom, but it also increases the amount of debris you’ll need to dispose of. Consider the size of your waste container and make sure you have enough space for all the cut pieces before starting the cutting process.

In summary, cleaning up after cutting a cast iron tub with a sawzall requires proper safety precautions and disposal methods. Make sure to wear protective clothing, avoid using water for cleanup, and check with your local waste management facility for proper disposal methods.
