How Far Apart Should Bath Legs Be?

When planning to install a bathtub in your home, it's crucial to consider the proper placement of the bath legs to ensure a stable and safe setup.

The distance between your bath legs can play a significant role in the overall security and comfort of your bathing experience.

In this article, we will discuss how far apart your bath legs should be as well as some other factors to consider in your bathroom design.

Bath Leg Considerations

When you're installing a new bathtub, one of the key considerations is the placement of the bath legs, as they play a crucial role in supporting the weight of both the tub and the water inside it.

In general, bath legs should be positioned correctly to ensure stability and even distribution of the weight.

To begin with, you'll want to carefully examine the bathtub you've chosen.

Most tubs come with pre-installed legs, but some may require you to attach them.

Make sure to follow the manufacturer's guidelines for proper positioning; they're designed to ensure your bath is installed correctly and safely.

Placement of bath legs typically depends on the design and style of your bathtub. Here are some common styles:

1. Freestanding Tubs

Often, freestanding bathtubs have four legs, though they can also have two or even none, depending on the design.

For a standard four-legged tub, legs should be positioned at each corner, ensuring an even distribution of weight.

2. Clawfoot Tubs

These vintage-looking tubs are named for their claw-shaped legs. The four legs should be placed at the corners of the tub, just like with freestanding bathtubs.

3. Built-in Tubs

Built-in bathtubs often have support frames that hold the tub securely in place.

The legs might be less visible and positioned beneath the rim, but their placement should still ensure even weight distribution.

In all cases, it's essential to double-check that each leg is installed securely and evenly.

Make sure the legs are level, which you can achieve by using a spirit level. If adjustments are needed, you can use a leg leveler or shims to balance everything out.

Proper leveling prevents the bath from rocking or moving when you're using it, which is essential for a pleasant bathing experience.

The Importance of Accurate Bath Leg Spacing

Bath leg spacing is crucial in ensuring the stability and safety of your bathtub.

Here are a few reasons why accurate bath leg spacing is important:

Even Weight Distribution

Firstly, accurate spacing helps distribute the weight evenly on the floor.

When you fill your bathtub with water, it becomes heavy, and spreading the weight across the legs helps prevent undue stress on any single point, thereby protecting your bathroom floor from potential damage.

Prevents Wobbling and Movement

Secondly, proper spacing prevents wobbling and movement when you enter or exit the bathtub.

As you step in or out, any instability can lead to slipping, falling, and possible injuries.

By ensuring that the legs are evenly spaced, you increase the stability of the tub and make it safer to use.

Extend Lifespan of Bathtub

Lastly, accurate leg spacing plays a role in maintaining the integrity of the bathtub itself.

Uneven leg spacing can cause distortion or cracking in the material over time, leading to potential leaks and other issues.

By positioning the legs correctly, you can extend the lifespan of your bathtub and keep it functional for years to come.

When you install your bathtub or hire a professional for the job, make sure to follow the manufacturer's guidelines on leg spacing.

Step-by-Step Guide: Measuring Bath Leg Spacing

Bath leg measurement refers to the distance between the legs or support points of a bathtub.

Correctly measuring this space is essential for stability of the bathtub and to guarantee it fits perfectly in your bathroom space.

Here are the necessary tools you will need:

  • A measuring tape or ruler
  • A pencil or chalk for marking (optional)
  • A notepad or digital device for note-taking

Let's break down the process into simple steps:

Clear the Area

Ensure the area around the bathtub is free from any obstructions. This includes bathmats, toiletries, or any decorative items. A clear space allows for accurate measurement.

Begin with the Length

Place the start point of your measuring tape at the center of one of the bathtub legs on one side.

Stretch the tape directly across to the center of the opposite leg. Note down this measurement. This will give you the length spacing between the legs.

Measuring the Width

For bathtubs with four support legs (like clawfoot tubs), you'll also need to measure the width.

Start your measuring tape at the center of one of the bathtub legs at the head or foot of the tub.

Stretch it out to the center of the adjacent leg on the same side. This will give you the width spacing between the legs.

Account for Differences

Some bathtubs might have irregular spacing or might not be perfectly symmetrical.

Always measure both sides (and, if necessary, both ends) to see if there are any differences in the leg spacing.

This is particularly crucial if you’re considering a custom-fit or non-standard installation.

Record the Measurements

Always jot down your measurements immediately to ensure accuracy.

If you're planning to buy a new bathtub or bath support structure, take these measurements with you to ensure compatibility.


It’s always a good idea to double-check your measurements. This will confirm your numbers and can help prevent future issues or mistakes.

How Do I Ensure My Bathtub is Level?

First, place the bathtub in the desired location, ensuring it is centered and aligned with the surrounding walls and plumbing fixtures.

Using the tape measure, measure the distance between the bathtub legs on both the left and right sides. Note these measurements on the paper.

Make sure that the recorded measurements are equal. If they are not, adjust the legs until the leg spacing is consistent on both sides.

Then place the level across the top of the bathtub, spanning the width of the tub. Adjust the legs as needed until the bubble within the level is centered, indicating a level bathtub.

Once the bathtub is level and the leg spacing measurements are equal, mark the final leg positions on the floor with a pencil for future reference during the installation process.

Bath Leg Measurement Depends on Your Bathtub Type

Generally, bath legs should be positioned at the corners of the bathtub, providing stability and support.

Always refer to the manufacturer's guidelines for installing and positioning bath legs to ensure optimal safety and functionality.

When installing your bathtub, you should consider factors like the bathtub material, size, and weight to determine the appropriate distance between the bath legs.

Lighter bathtubs made of acrylic or thin fiberglass may require additional support, while heavy bathtubs made of cast iron or stone resin may require stronger and more spaced out legs.

Lastly, remember to consider the type of floor your bathtub is being installed on, as different flooring materials may require additional support or reinforcement.

No matter the specific requirements for your bathtub and bathroom, always consult with a professional plumber or contractor for the best results.

With this information, we hope you are able to get the accurate measurement on your bath legs.
