Bathroom renovations are tricky, though. They can be both difficult and expensive. But instead of holding off on bathtub replacement because of cost concerns, you could decide to renovate your bathtub yourself. A DIY job takes a bit more of your time, but it can be worth doing to save on installation costs and labor. If cost is the main concern, there are still ways to save while going through a professional.
If you decide to go through with renovating your own tub, there are important steps to take and important things to consider. Here are some tips, tricks, and things to consider when it comes to how to replace a bathtub yourself.
Cost Considerations
The first thing to consider is the cost—one of the most important things to many people when it comes to bathroom remodeling. Replacing a bathtub can cost between $1,390 and $7,246 depending on the cost of the replacement bathtub, the cost of materials, the cost of replacing plumbing, site and surface cleanup labor (if you use a professional), and the price of a permit. The labor, materials, plumbing, cleanup, and permit can cost between $400 and $2,000—depending on what you choose to use. There are ways to reduce the cost of labor—and still be able to use professional help—by working with an installer who will do everything they can do to keep your remodel affordable.
One of the major costs of replacing a bathtub is the cost of the new bathtub. You can find a simple acrylic tub starting at $300. On the other hand, a high end claw foot tub might cost up to $7,000. There’s a wide variety of tubs to choose from, but it’s important to choose one that will meet your needs and your budget. If you’re unsure of how to find a tub that fits what you need, we can help you find what works best for your bathroom. Here are some general budget guidelines:
- $1,000 - With this budget, you can start with an acrylic tub and have about $300 to cover additional materials. A $1,000 budget will also mean you will need to primarily use DIY labor. But with this type of budget, you’re able to figure out how to replace a tub without breaking the bank.
- $2,500 - With this budget, you can get a tub around $500-$700. The tub could be acrylic, cast iron, steel, or even fiberglass. The remaining $2,000 would cover professional labor and supplies, so you can be sure that the tub will be installed with top tier professionalism.
- $5,000 - With this budget, you can choose more types of tubs and still have a professional installation. You could choose from clawfoot, walk-in tubs, soaking tubs, and more. With a lower budget, you’re restricted to tubs that are the same size as your old one. A higher budget also allows you to redesign the tub space and make the area how you want it to look.
- $10,000+ - With the highest budgets, you can completely redesign the look and feel of your bathroom. You can choose any tub you like—including high-end whirlpool bathtubs and more. In addition, you may choose to add a shower to change your bathroom experience. A $10,000 budget could make that possible.
Next Steps
Once you’ve set your budget and picked your tub, there are still a few things you should consider before starting on the removal:
- Do you need a permit? Bathroom remodels that involve plumbing will often need permits to ensure the project is safe, and you won’t accidentally introduce a major bathroom leak. A permit may cost $400–$2,000 depending on the extent of your renovations and how many components (plumbing, electrical, and building) your renovation will require. You’ll also receive inspections from an expert that ensures the plumbing work is good to go. While the permit adds extra cost and work, it can be a beneficial safety net to make sure your renovations are plumbing safe.
- Are you going to use a contractor? Contractors are a way to ensure that an installation is done correctly and effectively. While using a contractor can add to the price of replacing a bathtub, it could be worth the cost to make sure everything is done correctly. You’ll need to evaluate your own situation to make the right decision for your bathroom.
- What’s the plan for the installation? Whether you choose to use a contractor or to do it yourself, you’ll want to make sure you have a plan moving forward. Establish a timeline, determine the exact steps for your project, and make sure you have backup plans if something goes wrong. Once you have a plan for your project, you’re ready to move onto replacing your bathtub.
Steps to Removing Your Old Bathtub
To begin to figure out how to replace a bathtub, you’ll need to remove your old tub first. Before beginning this step, you’ll want to measure your existing bathtub. The current size of your tub may be the size of tub you need for your renovation. Even if you plan on completely changing the tub space, you’ll want to measure to determine if you’re able to remove the original tub from your bathroom. If you measure and find that removal will be difficult, you may need to also remove your toilet or sink before you begin.
Don’t forget to protect the rest of your bathroom during the renovation process. Put down a drop cloth or plywood to protect your flooring. Use tape and drop cloths along the walls where the tub might make contact when you’re removing it from the bathroom. Making sure your bathroom is protected from any additional damage will help keep your current project affordable and simpler.

Step-by-Step Guide
Remove the faucet and shower-head: To begin, shut off the water to the tub—usually the switch is found in an access panel in an adjacent room. Test the shut off by attempting to turn on the faucet. If no water comes out, you’re ready to move to the removal process.
Using your screwdriver, unscrew the covers for the faucet handle, faucet cover, and tub spout. Most faucets and spouts are held in place with Allen screws, and most of them are either visible or in recesses underneath the fixtures. Once the faucet is removed, unscrew the showerhead arm as well. If you plan on reusing any of these parts, save them in a safe place for later use.
Remove the drain and disconnect it: With the screwdriver, remove the overflow plate. If applicable, pull out the drain assembly. If there’s also a mounting plate, unscrew that as well. Once all of the drain pieces have been unscrewed, it’s time to disconnect the drain. To disconnect the drain, remove the strainer (if applicable) first. The strainer just needs to be unscrewed. Remove any additional parts—like a stopper and rocker assembly—if they’re present in your drain. Finally, use the strainer wrench to remove the drain flange (or part around the draining hole).
Disconnect the pipes: The next step is to disconnect the tub from the pipes. You’ll need to find the access panel to the plumbing, which is typically located behind the bathtub or underneath it. In the access panel, you’ll need to disconnect the waste-and-overflow (WO) unit from the drain line. Your WO unit could be screwed in, so you may need to remove anything that is holding it in place with your screwdriver. If the part is cemented plastic, you’ll need to cut through the pipe. Remove the WO unit.
Remove the surround: The surround of your bathtub will vary depending on how your tub is shaped, how it’s attached to the wall (if it is), and what your new tub will need. If the walls have tiles, you’ll need to use the pry bar to remove approximately 8 inches of tile before you can remove anything else. Next, use the utility knife to cut through the drywall around the tub. Check the measurements of your new tub, and make sure you cut at least an inch above the new dimensions. If the wall is plaster, you may need to use the reciprocating saw instead—making sure to keep your cuts shallow to avoid cutting through pipes or electrical wiring.
If you have an older tub, it may be glued to the drywall. If so, you’ll need to pull out the drywall with a hammer or pry bar. Start at the top (about 1 inch above the new tub dimensions) and work your way down. Make sure you cover your mouth with a dust mask to avoid breathing in drywall, and make sure your surrounding floor and wall is protected.
Pry the tub from the wall: Using the crow bar, it’s time to pry the tub from the wall. Remove the nails or screws in the tub flange using the screwdriver. If there’s caulk instead, use the utility knife to cut through it. Use the crowbar to pry the tub about an inch away from the wall on all sides.
Lift and remove the tub: Using the crowbar, pry one end of the tub farther away from the wall and lift it onto the 2x4 planks of wood. Once the end of the tub is lifted up onto the planks, use the crowbar to pry the other side farther away from the wall. Finally, slide the tub out of the space and remove it from the bathroom.
How to Replace Your Bathtub: Once you’ve removed your old bathtub, you can begin replacing your bathtub. As you replace the tub, you’ll want to make sure you keep your floor protected.

Step-by-Step Guide
Place the new tub
Now that the tub area is cleared out, it’s ready for the new tub. Using cardboard or a leveling pad, slide the tub into the space—be careful not to damage the tub as you move it into place. Once the tub is in place, use the level to make sure the tub is completely level before finishing the installation.
Attach the overflow and shoe tube
Inside the tub, put the overflow into place, and use the screwdriver to tighten it in place. Then take the shoe tube and attach it to the overflow pipe. Take the other end and put it into the drain opening in the tub.
Add the flange
To put the drain flange in place, begin by rolling a rope of plumber’s putty and placing it around the drain hole. Hold the shoe tube with one hand and screw the drain flange into place. Use the strainer wrench to tighten it. Using the putty knife, clear away the extra plumber’s putty.
Connect waste-and-overflow unit
Using the access panel, attach the waste-and-overflow (WO) unit. Test if it’s in place by plugging the stopper and running water. If there are signs of wetness, tighten the unit more until there’s no leak.
Add the surround
Once the plumbing is tightened, check that everything is level. Then use the caulk to seal the tub all around the bathtub. Finally, you need to add the surround for the tub, if your tub needs that. If you are adding tiling, place it around the tub and seal it.
