Installing a freestanding bathtub can be a fantastic addition to your bathroom, providing a luxurious and elegant centerpiece. Unlike traditional built-in bathtubs, freestanding tubs offer flexibility in placement and design, allowing for a stunning focal point. If you’re considering installing a freestanding bathtub in your home, this comprehensive guide will take you through the step-by-step process, ensuring a successful installation and years of enjoyment.

Let’s get started!

What Is a Freestanding Tub?

A freestanding tub, also known as a standalone tub or a soaking tub, is a bathtub not attached to any surrounding walls or fixtures. It is designed to be a self-supporting fixture and is usually placed in the bathroom as a centerpiece or focal point.

Freestanding tubs are typically made from acrylic, cast iron, or stone and come in various shapes and sizes. They are known for their aesthetic appeal and luxurious feel, often associated with spa-like experiences.

One of the distinctive features of freestanding tubs is that they can be placed anywhere in the bathroom as long as there is proper plumbing access. They are not constrained by the need for wall support or fitting into a specific alcove or corner like traditional built-in bathtubs. This versatility gives homeowners more freedom in designing their bathroom spaces.

Most freestanding tubs often have a more visually striking appearance compared to built-in tubs. They can have ornate or modern designs with wide rims or sleek edges. Some models also include integrated jets or whirlpool systems for added relaxation.

With this in mind, let us discuss the steps necessary for installing freestanding bathtubs.

Step 1: Planning and Preparation

Before diving into the installation process, there are a few essential considerations to keep in mind:

  1. Location: Choose a suitable location for the freestanding bathtub, ensuring it fits comfortably within the available space. Consider factors such as proximity to plumbing lines, structural support, and access for installation.
  2. Measurements: Measure the tub and bathroom dimensions to ensure a proper fit. Consider any walls, fixtures, or other obstacles that may affect the positioning of the tub.
  3. Plumbing and Electrical: Ensure the existing plumbing and electrical connections are compatible with the freestanding bathtub. Seek professional assistance if modifications are required.
  4. Floor Support: Verify that the master bathroom floor can support the tub’s weight, particularly when water-filled. Reinforce the floor drain if necessary, consulting a structural engineer if needed.
  5. Accessibility: Ensure adequate access to the bathroom and the space required to maneuver the tub into place. Measure doorways, hallways, and stairwells to guarantee a smooth installation process.

Step 2: Gathering Materials

Step 3: Prepare the Plumbing

If your bathroom already has existing plumbing connections in the desired location for the freestanding tub, skip Step 3. Otherwise, follow these instructions:

  1. Shut off the water supply to the bathroom. Locate the main water valve and turn it off.
  2. Remove the existing bathtub and disconnect the plumbing connections, including the drain and overflow assembly.
  3. Install the necessary piping and fittings, extending them to the desired drain location for the freestanding tub. Consult a professional plumber if you’re unsure about this step.

Step 4: Installing the Drainage System

Proper drainage system installation is crucial for the functionality of the freestanding bathtub. Follow these steps:

  1. Locate the bathtub’s drain hole and attach the drain assembly according to the manufacturer’s instructions.
  2. Connect the drain pipes to the existing plumbing system, ensuring a watertight seal.
  3. Test the bathtub drain line system by filling the tub with water and checking for leaks. Make any necessary adjustments to acquire a proper seal for the drain body.

Step 5: Placing the Bathtub

Now it’s time to position the freestanding bathtub in its designated location:

1. Ensure the entire bathroom floor is spotless and free of any debris or obstacles.

2. With the help of a friend or skilled personnel, carefully lift the tub and place it in its desired position, ensuring it aligns with the plumbing connections. Use furniture sliders or a dolly to move the tub without scratching the floor.

3. Use a spirit level to ensure the tub is perfectly balanced, and adjust the placement if needed. This step is crucial for proper drain and waste location and a stable installation.

4. Mark the tub’s final position on the floor using a pencil or tape. This reference will help you align the tub correctly during the next steps.

5. Place shims under the bathtub to level it properly and provide support. This will prevent any rocking or movement during use.

Step 6: Connect the Drain and Overflow Assembly

  1. If not pre-installed, refer to the manufacturer’s instructions to assemble the drain and overflow components.
  2. Apply the plumber’s putty to the underside of the drain flange and insert it into the drain hole of the bathtub. Tighten the locknut from underneath to secure the drain assembly.
  3. Attach the overflow cover to the overflow opening of the tub, securing it with the provided screws. Make sure it is properly aligned and tightened.
  4. Connect the drainpipe and overflow pipe to the respective plumbing connections. Apply plumbers’ tape to the threaded connections for a watertight seal.

Step 7: Securing the Bathtub

To ensure stability and prevent movement, secure the freestanding bathtub to the floor:

  1. Check the manufacturer’s instructions for any specific recommendations regarding securing the tub.
  2. Use brackets or mounting hardware designed for freestanding bathtubs to secure the tub to the floor.
  3. Follow the tub manufacturer guidelines to securely attach the brackets or hardware, ensuring they are hidden from view.

Step 8: Sealing and Finishing

The final step involves sealing the bathtub and adding the finishing touches:

  1. Apply a bead of silicone adhesive or sealant around the bathtub’s base where it meets the floor. This will create a watertight seal and prevent water damage.
  2. Use a caulking gun to apply the sealant, ensuring a smooth and even application.
  3. Wipe away any excess sealant and allow it to dry according to the manufacturer’s instructions.
  4. Check for any visible gaps or imperfections in the sealant and apply additional sealant if necessary.
  5. Clean the bathtub thoroughly to remove any dust or debris from the installation process.
  6. Following the manufacturer’s instructions, install any additional fixtures or accessories with the freestanding bathtub, such as deck-mounted tub faucets or handheld showerheads.
  7. Test the functionality of the bathtub, including the water flow, drain system, and any attached fixtures. Make any adjustments or repairs as needed.
  8. Finally, inspect the overall appearance of the installation. Ensure that the bathtub is level, securely fastened, and aesthetically pleasing.

For stubborn stains, prepare a baking soda paste and water or use vinegar diluted with water. Apply the mixture to the stained areas, let it sit, and scrub gently with a soft brush. Rinse thoroughly.

d. Avoid Abrasive Tools

Refrain from using abrasive sponges, brushes, or cleaning tools that may scratch or damage the bathtub’s surface. Opt for soft materials to preserve the bathtub’s finish.

2. Preventive Measures

Taking preventive measures can significantly extend the lifespan of your freestanding bathtub. Here are some key steps to consider:

a. Use Bath Mats

Place non-slip bath mats inside the tub to prevent accidental slips and falls. This also helps protect the tub’s surface from scratches caused by hard or sharp objects.

b. Avoid Heavy Items

Refrain from placing heavy items on the edges or inside the bathtub, as they may cause cracks or damage to the structure. Be cautious when handling metal objects to prevent scratching.

c. Mind the Water Temperature

Extreme hot or cold water can cause stress on the bathtub’s material, potentially leading to cracks or other structural issues. Maintain a moderate water temperature to minimize such risks.

d. Regular Inspection

Periodically inspect your freestanding bathtub for any signs of damage, such as cracks, leaks, or loose fittings. Addressing issues early can prevent them from worsening and causing further damage.

3. Dealing With Common Issues

Even with proper maintenance, certain issues may arise. Here are some common problems and their solutions:

a. Cracks

If you notice a crack in your bathtub, it’s crucial to address it promptly. Depending on the severity, you may need to consult a professional for repair or replacement. Small cracks can often be repaired using epoxy adhesive or specialized repair kits.

b. Stains and Discoloration

Over time, your freestanding bathtub may develop stains or discoloration. Regular cleaning can help prevent this, but you may need to consult the manufacturer’s recommendations or seek professional assistance for persistent stains.

c. Dripping or Leaking Faucets

Leaky faucet holes not only waste water but can also damage the bathtub’s surface and surrounding areas. Check the wall mount faucet regularly for leaks and repair or replace them.

d. Clogged Drains

To prevent clogged drains, use drain catchers or filters to trap hair and debris before they enter the plumbing system. Regularly clean the drain catchers to maintain optimal water flow.


Installing a freestanding bathtub can be a satisfying and enjoyable project. Following these step-by-step instructions, you can install a freestanding bathtub and create a beautiful and relaxing centerpiece for your bathroom.

Frequently Asked Questions on Tub Installation

a) Are freestanding tubs hard to install?

Freestanding tubs can vary in complexity when it comes to installation. The difficulty level depends on various factors, such as plumbing requirements, structural support, and existing infrastructure. In some cases, professional assistance might be necessary to ensure proper plumbing connections and to address structural modifications.

b) Do you tile under a freestanding bath?

Tiling under a freestanding bath is not necessary for its installation. Since freestanding baths are not fixed to the floor or wall, there is no need to tile beneath them. Tiling is typically done up to the edges of the bath, ensuring a neat and finished appearance. However, it’s important to ensure that the area underneath the freestanding bath is properly prepared and leveled to provide a stable foundation.

c) How much room do you need between a freestanding tub and a wall?

The space between a freestanding tub and a wall depends on several factors, including the tub’s dimensions and the desired aesthetic. However, as a general guideline, it is recommended to have a minimum clearance of 2 to 4 inches between the tub and the wall. This allows for easier cleaning, maintenance, and access to plumbing fixtures.
