There’s nothing like unwinding and relaxing by soaking in a hot bath after a long day. Having a tub is an excellent addition to any home, but it can lead to overcrowding if not appropriately planned. Let’s explore some common bathtub dimensions to ensure a relaxing and cohesive bathroom for your home.

An average alcove bathtub is 60 inches long, 32 inches wide, and 16 inches deep, while more oversized freestanding tubs can be 72” long, 32 inches wide, and 25” deep. Smaller tubs can be closer to 54 inches long, and oval tubs can be more expansive, measuring 42 inches wide. There should also be a minimum clearance of 22 inches on the side of the tub.

Bathing has been a social tradition throughout history, and many revere it as sacred in many cultures. While western culture doesn’t practice public bathing, it is still a fantastic way to get in tune with yourself. Creating a relaxing space requires knowledge of bathtub dimensions: style, pros, cons, and how it affects your space.

What Are Average Bathtub Dimensions?

The most common type of tub is the alcove tub that doubles as a shower. This is a great space-saving option for those who want access to both a tub and a shower. The average size of this style tub is 60”x32”, although, of course, they come in all sizes.

Persons over six feet tall will want to choose an oversized tub with an average size of 72”x42”x23”. If you’re selecting an oversized tub, you’ll want a minimum of 70” long.

Oversized Soaker Bathtub Dimensions

If you are a taller person, an oversized soaker tub is a fantastic choice. For example, the dimensions of the TOTO Aimes Soaker Bathtub are approximately 71”x36”x24”. The average tub is around 60”, which means this tub will accommodate taller individuals.

The square shape of this tub works well if you want the look of a freestanding tub but are lacking in space. Square shapes are great at maximizing their available space. Additionally, soaker tubs hold more water than the average tub to allow full submersion.

Pros Of An Oversized Soaker Bathtub

One of the best draws of this tub is its large size, including its depth. This size is a great option for taller individuals or folks who just want a deeper tub to soak in.

An oversized soaker tub is also a possible option if you are looking for a two-person soaking tub. An oversized tub would be preferable for two average-sized people as it could be too small for two taller people. Lastly, a square-shaped tub is a great way to conserve space, especially if your bathroom is smaller.

Cons Of An Oversized Soaker Bathtub

For smaller individuals, this tub may be too large. A tub that’s nearly six feet long can be a challenge for shorter people to stay seated without sliding down. However, there are ways to help with this problem, such as a bath seat or sticky pads for the bottom.

Another con of this tub is the size in reference to square footage in the bathroom. Not everyone has ample space for bathrooms, so having such a sizeable separate bath simply isn’t an option for some.


Oval Soaker Bathtub Dimensions

Oval soaker tubs are another option if you want a more luxurious feel to your tub. For example, the TOTO Pacifica Oval Soaker Bathtub features an elegant shape and extra-large size, making it great for taller folks.

It easily becomes the focal point of the whole bathroom, measuring in at a whopping 72”x24.5”x42”; the Pacifica Oval Soaker is an absolute beast.

Pros Of An Oval Soaker Bathtub

Certainly, the biggest pro of oval tubs is they tend to provide a bit more room to spread out. The extra width creates a more relaxing bath experience, plus the rounded edges are comfortable. Another pro of this tub design is the striking design, stepping away from the typical angular edges of rectangular tubs.

Cons Of An Oval Soaker Bathtub

A big con of this tub is also one of its positives — its large size. Because of the oval shape, it does cost you precious, unused space in your bathroom. For those looking to conserve as much space as possible, choosing a rectangular design could be a better option.

Similar to an oversized bathtub, this may not be a great option for smaller people. The extra space can make it challenging to stay upright and seated. Using traction pads or a removable bath seat are great additions to make this tub usable to smaller individuals.


Freestanding Bathtub Dimensions

Freestanding tubs are made to rest on the floor versus fully installed like a drop-in or alcove tub. For this freestanding bathtub, the dimensions are more indicative of an average-sized tub. Freestanding tubs are usually considered the most stylish tub types because of their many shapes and sizes.


This specific freestanding tub is approximately 67”x30”x21”, making it slightly larger than the average tub.

Pros Of A Freestanding Bathtub

Arguably the biggest pro of a freestanding tub is its sleek and classic look. A freestanding tub simply never goes out of style and can hold its value for years to come. Another pro is that freestanding tubs come in larger sizes and accommodate taller individuals.

Cons Of A Freestanding Bathtub

One of the biggest cons of a freestanding tub is the amount of space that it takes up. When it comes to designing bathrooms, every inch of space is valuable, especially for smaller homes.

Unlike alcove or drop-in tubs, freestanding tubs typically don’t double as showers. Of course, it is possible to add a shower head. However, it’s not very common for most homes.

Alcove Bathtub Dimensions

An alcove bathtub is a tub enclosed by walls and is the most common tub for homes. While alcove tubs are considered outdated, there are tons of beautiful, modern alcove tubs on the market now.


With this alcove tub sizing in at approximately 60”x26”x17”, it’s clear that this is an average-sized model. Typically you will find the alcove tub enclosed with three walls, although it’s possible for them to be open.

Pros Of An Alcove Bathtub

One draw of an alcove tub is its space-saving ability. If you are tight on space but still want the luxury of a bath, an alcove tub is a great option.

Cons Of An Alcove Bathtub

While alcove tubs have their place in the bathroom, there are several large drawbacks to be aware of. The most notable con of alcove tubs is their size. While there are larger alcove tub options, the average size is around 60”, which is too small for some.

Another con of this style tub is the enclosure. Since alcove tubs typically have three walls, this may not be the best option for individuals with claustrophobia.

Drop-In Bathtub Dimensions

Unlike the alcove tub, a drop-in tub is just the tub shell dropped into a built tub exterior. This tub measures around 60”x32”x23”, making it a more average size and design. Drop-in tubs are usually installed with a decorative frame and are typically an open design.


Pros Of A Drop-In Bathtub

While this specific tub is a smaller or average size, drop-in tubs come in many different sizes. Drop-in tubs are sometimes installed flush to the floor, giving a luxurious spa design. Since this type of tub is usually uses an open concept design, this is a good choice for claustrophobic individuals.

Cons Of A Drop-In Bathtub

One of the cons of a drop-in tub is the space that it takes up. While they can certainly double as a shower, they usually function as tubs alone. This feature can be a hassle for those looking to save some space.

Bath Side Clearances

Nobody likes a cramped space, especially in a room designed for cleanliness and relaxation. In homes with limited space, it’s typical for the bathroom to take a hit when it comes to space. A tub is often considered a luxury in homes, much less a tub that is separate from the shower.

The minimum bath side clearance for a 24 inches tall tub is approximately 22 inches. If you have a little more space to play with, try and leave at least 44 inches from the edge of the tub to the wall. This extra room will allow you to dress and undress beside the tub without feeling cramped or hitting the wall.



In conclusion, knowing your bathtub dimensions can save you a whole lot of heartache in the long run. The average tub measures about 60” in length, 30” wide, and 16” deep.

The average oversized tub is 72” long, 35” wide, and 25” deep, with some oval tubs measuring 42” wide. If you need a smaller tub, you can find some around 54 inches long. The minimum bath side clearance should be at least 22”, but 44” is the ideal minimum.

Between oversized soaker tubs and enclosed alcove tubs, there are options for everyone. Making sure that your bathroom is perfectly planned requires a deep understanding of bathtub dimensions.
