Close your eyes for a moment and imagine this: You’ve finally decided to upgrade your bathroom with a sleek, luxurious freestanding tub. You can already see yourself soaking in bubbles, wine glass in hand, candlelight flickering. But hold on—before you hit “buy,” have you thought about the size?

Too big, and it overwhelms your space. Too small, and you won’t get that deep, immersive soak you’re dreaming of. The right freestanding tub size isn’t just about aesthetics—it’s about comfort, functionality, and making the most of your bathroom layout.

In this guide, we’re diving deep into everything you need to know about freestanding tub sizes. Whether you have a compact space or a sprawling spa-like bathroom, you’ll find the perfect fit for your dream soak. Let’s get started!

What Are The Freestanding Tub Sizes Available?

Small Freestanding Tubs

Oversized soaking tubs will not be an option for you most of the time if you have limited bathroom space or plan to install one for the kids. 

That doesn't mean you can't get something luxurious; smaller freestanding tubs offer the perfect balance of function and style, giving you a spa-like ensuite retreat without hogging all the room in your bathroom. 

These freestanding tubs measure 48 to 60 inches in length, 28 to 32 inches in width, and 22 to 26 inches in height.  One great option is the 59" Freestanding Soaking Tub with Center Drain. 

It measures 59 inches in length and is a compact tub ideal for smaller bathrooms. Crafted from high-quality acrylic, it features a sleek, modern design with a center drain, providing both comfort and style. 

Standard Freestanding Tubs

For bathrooms with considerably more wiggle room, something smaller might look a bit out of place. A standard freestanding tub size should be the go-to for a spacious bathroom; they range from 60 to 70 inches in length, 30 to 34 inches in width, and 22 to 28 inches in height.  

Adults of above-average height can easily get cramped up in smaller tubs, but these standard tubs are spacious enough for a comfortable soak while still fitting well in most bathroom layouts.

Large Freestanding Tubs

Large tubs are perfect if you want to make every soaking experience cinematic. They give you ample space to stretch out and unwind while fitting the appeal for particular rooms like master suites and high-end home spas.

A large stand-alone tub is 70 inches or larger in length, 34 to 40 inches wide, and 24 to 30 inches high. One of the deeper models, like the 71" Freestanding Hydro Massage Whirlpool Bathtub, allows even greater immersion.

Boasting eight water jets—two in the back area, four in the body zone, and two in the foot zone. It offers a soothing hydro-massage experience for those who prefer long, stress-reducing soaks.

How to Choose the Right Tub Size for Your Bathroom Layout

For anyone looking to remodel or design a space, picking a freestanding tub goes beyond the aesthetic appeal of a particular model. There are a lot of things that need to be considered before you install one, some of which are:

Getting accurate measurements of your bathroom is the first step you need to take before browsing catalogs of freestanding tubs.

Start by measuring the length and width of the area where you will place the tub. Record very accurate measurements with a tape measure and label them on the floor with painter's tape so you can get a clearer idea of how a particular tub will fit in. 

Ensure to leave adequate space around the tub for easy maintenance and access. Ideally, you want to have a clearance of at least 6 inches on all sides, which is recommended for ease of access.

Beyond the space itself, you want to ensure that the process of getting the tub into your space does not become problematic. To ensure that the tub will easily fit into the bathroom, measure doorways and corridors and find out if they are wide enough for your chosen tub to be delivered and installed.

Water Capacity

An average freestanding tub size might hold water typically ranging from 40 to 90 gallons, but the sizes vary for different models. The larger your tub, the more water is required to fill it, so you're more likely to make your water bills, as well as your heating costs, go up if you buy one.

Before choosing a tub, check your water heater capacity—a good rule of thumb is that your water heater should be able to supply at least ⅔ of the tub's total capacity with hot water. 

For example, if your tub holds 60 gallons, your water heater should provide at least 40 gallons of hot water. 

Also, if conserving water is a concern of yours, find a tub with a low capacity of under 60 gallons or one designed with water efficiency in mind.

Carrying Capacity

Another thing to consider is whether the model is a single or a two-person freestanding bathtub size. Single bathtubs like the 67" Freestanding Whirlpool Tub typically include one sloped backrest on end for reclining and sitting straight while bathing.

Double-ended tubs, however, feature sloped backrests on both ends with a middle drain, which is ideal for couples or people who would like extra room to stretch out.

Installation Tips for a Perfectly Positioned Freestanding Tub

Ensure Proper Floor Support

There have been a few occasions when people have seen their tubs fall from the second floor because the floor could not take the load. Tubs, especially cast iron or stone types, are extremely heavy if filled with water. 

Make sure your bathroom floor supports the weight of the tub before installation. Strengthening of the subfloor may be necessary if your bathroom is on the second floor to prevent any structural damage.

Plan for Plumbing Accessibility

Since freestanding tubs are not built into walls, the plumbing setup requires careful planning. Make sure:

• The drain and water supply lines are properly aligned with the tub's design.
• The floor drain location matches the tub's bottom drain placement.
• Exposed freestanding or wall-mounted faucets are installed at the correct height for easy access.

Level the Tub for Stability

You can avoid water tilting to one side of your tub by ensuring that the tub is absolutely level when you assemble it. Freestanding tubs usually come equipped with adjustable feet so that you can make the necessary adjustments of a few inches in height if the floor happens not to be level.

Seal and Secure the Tub Correctly

After positioning the tub, attach the drain and water supply pipes firmly. Seal around the tub's base with waterproof caulking if there is a need, particularly if near a wall. Test water flow through the faucets and drain to identify any leaks before finalizing the installation.

Finding the Perfect Freestanding Tub for Your Space

Coming out of the bathroom feeling refreshed is a must to be prepared to face the day or get a good night's rest. A freestanding tub is certainly one of the best ways to recharge yourself at any point in the day and choosing the right tub is key to having an amazing experience.
