Cast iron tubs boast a solid iron core with a porcelain enamel finish, available in drop-in, apron (alcove), and freestanding styles. Their enduring durability and excellent heat retention have made them a favorite for centuries, and they're still highly sought after today.

According to Dan Stout, a freelance writer,

“Cast iron tubs are valued for their strength and water heat retention. But removing them can be an intimidating task. If you want to tackle this chore DIY, you’ll need a good plan, some protective gear and a little determination.”

You might be inclined to call in a pro if you need to remove or replace your cast iron tub, given the perceived complexity of the task. However, with some persistence and hands-on work, you can move your cast iron tub yourself to create space for a stylish new one.

Common Complications of Removing Cast Iron Tubs

Exceedingly Heavy

Cast iron bathtubs are famously heavy, demanding extra floor reinforcement to bear their weight. A standard cast iron tub typically ranges from 250 to 500 pounds, with the exact weight varying based on its dimensions. These standard clawfoot tubs are usually sized between 50 to 72 inches in length and 37 to 32 inches in width.

Difficult to Get Through Doors

The real challenge arises when you need to shift the tub from its vertical position, which is more convenient for navigating corners and doorways, to its final horizontal setup. Lowering these heavy units safely into place can be quite a struggle. Most interior doorways are in the range of 28 to 32 inches, which can make it tough to move whole bathtubs through them.

Requires Several Helpers

Working alone simply isn't an option when removing a cast iron tub. It's common for people to overestimate their abilities and, unfortunately, get injured. So, let's prioritize safety and ensure everyone stays safe at work. For a complex task like this, it's best to have a team of three or four workers.

 Tools and Supplies Needed:

• Angle grinder
• Safety goggles
• Dolly
• Work gloves
• Caulk remover
• Hearing protection
• Drain plug wrench
• Respirator
• Reciprocating saw
• Contractor bags
• Screwdriver
• Plywood
• Wrench

1. Gather Tools and Prepare Your Bathroom

It's essential to take the right precautions to shield your home and prevent any accidental water damage or unsightly marks on your floors and walls. According to Abbey Hughes, a content specialist,

“To ensure your bathroom stays safe during this process, here's what you should do:

• Shut off the water: Locate the valve near your main water supply and turn it off to cut off the water for your entire house.
• Protect your flooring and walls: If you're not replacing the flooring, lay down a drop cloth or heavy-duty flooring paper beneath the tub's placement area. For added protection, consider using ½-inch plywood.
• Secure delicate items: Store any breakable objects, like mirrors or glass items, in another room to keep them out of harm's way during the project.”

2. Remove Fixtures

If you're working with a clawfoot tub, the first step is to drain the system. Then, disconnect any bolts leading to the supply pipes by removing the mixing valve, using a wrench. In the case of a more modern bathtub, take off the faucet by either twisting or pulling the fixture, depending on the type of spout. To complete the process, use a screwdriver to remove the overflow and handles.

3. Detach the Drain

To get rid of the tub drain, use a wrench or pliers to loosen and remove it. Then, take out the waste line. In older bathtubs, you might have to cut the waste line if necessary. If the pipes are not easily accessible, you can typically reach the tub pipes by going through a crawlspace or basement. Once you've exposed the drainpipe, it's a good idea to place a cloth in the opening to prevent any sewage gas or fumes from leaking out.

4. Get Rid of Any Caulk

To get rid of the silicone caulk along the sides or base of the tub, you have a few options. You can use a caulk remover, a screwdriver, a scalpel, or a razor blade to carefully cut through it.

5. Demo Surrounding Material and Remove Tub

When your bathtub isn't freestanding, the initial task involves taking apart the surrounding materials. This typically includes removing any tiles around the tub or attached to the wall, which is common for alcove bathtubs. Once the area is prepped, it's time to go ahead and remove the bathtub. Whether you choose to extract it in one piece or break it down, consider these different removal methods to successfully get your old tub out of the bathroom.
