Thinking about upgrading your bathroom? Installing a new bathtub can transform your space into a relaxing oasis. Whether you’re dreaming of a sleek modern design or a classic clawfoot tub, the right installation can enhance both functionality and aesthetics.
But before you dive in, it’s essential to consider the costs involved. On average, you might spend anywhere from $1,000 to $5,000, depending on the type of tub, materials, and installation complexity. With a bit of planning and the right guidance, you can ensure your bathtub installation goes smoothly and fits your budget. Let's explore the steps to make your bathtub dreams a reality.
Understanding Bathtub Installation
Installing a bathtub involves several crucial steps to ensure everything functions correctly. You need to consider the type of bathtub you choose and gather the necessary tools and materials for a successful installation.
Types of Bathtubs
- Alcove Bathtubs: These fit between three walls and optimize space. They're ideal for standard bathroom layouts.
- Freestanding Bathtubs: These stand alone and create a focal point. They suit larger bathrooms and modern styles.
- Drop-in Bathtubs: These are installed into a deck or surrounding structure. They offer flexibility in design.
- Corner Bathtubs: These utilize corner space, providing a unique design. They work well in smaller bathrooms.
- Tools:
- Screwdriver: For screws in the installation.
- Level: To ensure the bathtub sits evenly.
- Tape Measure: For precise measurements during setup.
- Pipe Wrench: To connect plumbing fittings.
- Materials:
- Bathtub: Choose based on your needs and style.
- PVC Pipe: For drainage and plumbing connections.
- Mortar or Shims: For leveling the bathtub properly.
- Caulk: To seal joints and prevent leaks.
Preparing for Installation

Preparing for bathtub installation involves several key steps, including measuring your space and selecting the right location. Taking these steps ensures a smooth and successful installation.
Measuring Space
Measure the area where you plan to install the bathtub. Use a tape measure to determine the length, width, and height of the space. Ensure there's adequate room for the bathtub style you choose—typical alcove bathtubs range from 60 to 72 inches in length, while freestanding tubs can vary significantly. Always account for plumbing fixtures and maintain a minimum of 2 feet of clearance around the tub for comfortable access.
Choosing a Location
Select a suitable location for your new bathtub based on your measurements. Consider proximity to existing plumbing for easier installation. Higher accessibility to natural light enhances the bathing experience. Avoid locations near electrical outlets to reduce risks associated with water exposure. Prioritize stable flooring to support the weight of the filled bathtub, which can exceed 300 pounds.
Step-by-Step Installation Process

Follow these detailed steps to successfully install your new bathtub. This guide covers removing the old bathtub and installing the new one.
Removing the Old Bathtub
Removing your old bathtub involves several critical steps to ensure a smooth transition.
- Disconnect the Water Supply:
Turn off the water supply by locating and closing the shut-off valves. Open the faucet to drain any remaining water from the lines. - Disconnect the Drain:
Unscrew the slip nuts to remove the drain assembly. Carefully lift the drain assembly out of place. - Separate the Tub from the Wall:
Gently use a pry bar to separate the bathtub from the surrounding walls. Avoid causing damage to the walls or the new bathtub. - Remove the Old Bathtub:
After detaching the bathtub from the plumbing and walls, lift it out of the alcove or designated area. Due to its weight, consider getting additional help during this step.
Installing the New Bathtub
Installation of the new bathtub requires precise measurements and proper techniques.
- Prepare the Area:
Clean the site thoroughly and ensure the subfloor is stable and level. Address any plumbing adjustments needed before setting the new tub in place. - Position the New Bathtub:
Carefully lower the new bathtub into the designated area. Align it properly to fit snugly against the walls and ensure it’s level. - Reconnect the Drain:
Attach the drain assembly by screwing the slip nuts back into place. Ensure a secure connection to prevent leaks. - Reconnect the Water Supply:
Turn the water supply back on. Test the faucet and check for leaks at the connections. - Seal the Joints:
Apply caulk around the edges where the tub meets the wall to create a watertight seal. Allow it to cure as per manufacturer instructions. - Finish the Installation:
Replace any surrounding fixtures or hardware. Clean up the area to enjoy your newly installed bathtub.
Plumbing Considerations

When installing a bathtub, plumbing considerations play a crucial role in ensuring a successful and leak-free setup. Focus on connecting the drain and water supply lines effectively.
Connecting the Drain
- Removing Old Setup:
Start by removing the old waste cover and washer located beneath the cover using a screwdriver if replacing an old bathtub. This step clears the way for a new drain installation. - Installing the Drain Spud:
Apply Oatey silicone sealant or plumber’s putty (avoid putting on ABS components) to the bottom of the drain spud flange. Press it firmly into the tub drain opening for a secure fit. - Assembling the Drain Elbow and Overflow:
Hand tighten the drain elbow onto the spud, ensuring that the elbow outlet faces out and away from the tub. Insert the overflow elbow through the tub overflow opening and hand tighten it with the threaded overflow lock nut. This ensures proper drainage. - Measuring and Cutting Pipes:
Measure and cut the overflow and drain pipes to the desired length for a precise installation. This step prevents excess stress on the connections and helps maintain proper water flow.
- Shutting Off the Water Supply:
Shut off the main water supply before you start working on the water supply lines. This prevents unwanted water flow during the installation process. - Routing the Supply Lines:
Route the water supply lines to the new bathtub. Ensure that the hot and cold lines are correctly positioned to deliver water to the appropriate faucet fixtures. - Connecting the Supply Lines:
Use adjustable wrenches to connect the supply lines to the tub’s faucet. Be sure to use Teflon tape on threaded connections to ensure a tight seal and prevent leaks. - Testing for Leaks:
Turn the water supply back on and test for leaks around the connections. Monitor all joints for any signs of water seepage to ensure a reliable and long-lasting installation.
Finishing Touches

Completing the bathtub installation requires careful attention to sealing, waterproofing, and adding fixtures. These steps ensure a durable and functional bathtub that enhances your bathroom experience.
Sealing and Waterproofing
- Apply silicone sealant where the drywall or finish wall meets the bathtub. Creating a watertight seal prevents water from seeping behind the tub.
- Use silicone sealant to seal joints between the bath rim and the finish wall. This step is vital for preventing moisture from entering the wall cavity.
- Ensure wall coverings are installed 1/16" above the enameled surface of the bathtub. This installation technique maintains a waterproof seal and protects your walls.
- When connecting the drain and overflow, apply a consistent bead of silicone sealant around the outer edge of the gasket. This practice establishes a reliable seal, preventing leaks and ensuring proper drainage.
- Choose fixtures that match your bathtub design for a cohesive look. Options include faucets, showerheads, and diverters that enhance functionality while complementing the overall aesthetic.
- Install grab bars for safety, especially in households with children or elderly individuals. Securely fastening these bars provides users with extra support when entering or exiting the tub.
- Add storage solutions like corner shelves or caddies for organizing bath products. This addition keeps frequently used items within reach and contributes to a tidy bathroom space.
- Consider using a shower curtain or glass door fitting for bathtub-shower combinations. These elements help contain water, preventing spills while adding a stylish touch.
- Incorporate bath mats and towels that coordinate with your bathroom decor. These accessories enhance comfort and elevate the overall ambiance of your space.
