Are all bathtubs of the same size?
Unfortunately, the answer is no. There is no universal size for all kinds of tubs even though that would make the planning much easier.
Sizes of bathtub vary, and as you’re going to see below, they depend a lot on the style of tub you want to place in your bathroom. That’s why knowing the standard bathtub dimensions for every type of tub is even more important.
Why does the size of a bathtub matter?
With living rooms and other large rooms, you have more leeway while allocating the space for your furniture and appliances.
But you don’t have this luxury with bathrooms.
They are usually the smallest room in any house, and you need to plan how to this space carefully. Sometimes, to make things right, you may even need to adjust your items by just an inch.
On top of that, there is no universal style of bathtubs; many of them are available with different designs, purposes, and of course, sizes.
There are various bathtub styles on the market.
Knowing the standard dimensions of each tub style is the first thing you must know if you want to plan your bathroom in an effective, convenient, and smart way.
Standard bathtub dimensions for every type of tub
This is the most common configuration, either in the form of only a bathtub or a bathtub-shower combo. It has one open side for easy access while the walls of your bathroom surround the other three.
An alcove tub.
If you have narrow and small bathrooms, alcove tubs are a great idea. This setup enables efficient use of your limited space and gives it a streamlined appearance.
But we can’t say the same thing for large bathrooms.
When your bathrooms are too long for a typical alcove tub, you won’t have small gaps to create the required alcoves. If you still insist on alcove tubs on those rooms, you may even need to build an additional wall to form the alcove.
The most common outer size of an alcove bathtub in small or older homes is 32 inches in width, 60 inches in length, and 18 inches in height.
The inner basin size varies a lot, decided by the thickness of the tub.
On average, it measures 45×22 inches at the bottom and 55×24 inches at the top. This should give enough comfortable space for a single adult to sit upright and submerge her or his legs. But you can’t really expect to sink down to submerge your torso and legs at once.
Tall adults will have a hard time stretching their legs, and their knees will usually poke above the water.
As large and spacious homes are harder and harder to afford these days, small bathrooms have become more popular. For them, the most obvious choice is forgetting about the tub and getting only a shower instead.
However, small alcove models are not impossible if you still want to squeeze in a bathtub.
You can get an alcove tub as small as 54x30x15 inches to be able to soak in water after an exhausting day at work. This is also worth considering for a kids’ bathroom.
Most long alcove bathtubs won’t fit in a typical large bathroom. But when you have the opportunity of a completely new project or remodeling, it’s still a solid choice.
They often have dimensions of 72x36x20 inches.
They enable tall people to fully extend their legs or even allow two adults to squeeze in.
As its name has pointed out, you don’t tuck a freestanding tub into an alcove in your bathroom. Instead, you can put it in the middle of the room to serve as its focal point.
They come in different sizes, styles, and shapes, but generally, this type is larger than a typical alcove tub. To understand the dimensions of freestanding tubs, we must go into detail of its two most popular styles: oval and clawfoot.
Oval freestanding tubs
They often have a minimalist, sleek appearance that goes well with most modern decor styles, providing ample space for after-work relaxing.

The most common size of oval freestanding tubs is 60 inches in length, 41 inches in width, and 24 inches in depth. But if this is too large for your bathroom, smaller models are available at down to 55x27x15 inches.
Clawfoot freestanding tubs
The clawfoot variant brings a romantic vibe and vintage appeal, which is fitting well to older types of houses, particularly Cape Cod, Craftsman, and Victorian.

The average length of a clawfoot tub falls between 60 and 66 inches. But larger and smaller sizes do exist, ranging from 54 to 72 inches. Clawfoot tubs also have a wide range of widths, which are usually from 30 to 40 inches.
But the main issue is their heights.
Usually falling between 24 and 30 inches, this style of tub requires bathers to stretch their legs to get in or out. As a result, people with mobility issues won’t fancy bathing with them much.
Homeowners who love to add the spa-style when remodeling or building a new bathroom, depth of the bathtub is one of the most important factors. This makes soaking tubs an ideal choice for them.
A soaking tub like this will give you a spa vibe to your bathroom.
Though you can call any tub that is deeper than average a soaking tub, Ofuro – the soaking tub style from Japan – is what most people have in mind when thinking of a deep tub built for soothing your body and mind.
A soaking tub usually has a depth of at least 27 inches, allowing bathers to submerge their necks while crouching on the floor.
Many modern-style models come with built-in seats and are up to 34 inches deep. And since they are intended for upright bathing, they are shorter than other types. Some even have a diameter of just 16 inches.
People usually have the wrong idea that corner tubs can save a lot of space in bathrooms. But compared to traditional alcove tubs, they take up more room.
Why is that?
The primary reason manufacturers increase their size is they want to provide a bathing space for two people or lounging.
Corner tubs are not as small as they seem to be.
A typical corner tub has a length and width of 60 inches and a height of 20 inches. If your bathroom can’t let it in, you can still fulfill your dream of a corner tub with a smaller model, which might be as small as 48x48x18 inches.
And when there is still plenty of space left, especially with master bathrooms?
Why not go all-in for a king-sized tub with the dimensions of 72x72x20 inches, which will even allow you to lounge with your favorite shows.
Bathtubs with the walk-in style are taller than an average model and come with a door.
They allow you to step into it with ease, so you will no longer need to swing or even stretch your legs to get in or out of it. People with mobility problems, general infirmity, or lack of balance will love walk-in tubs for that very reason.
They help reduce the risk of bruises and injuries from falling. Folks who usually need assistance to get in a tub now can even do it easily by themselves.
People with mobility issues will be happy with walk-in tubs.
Walk-in tubs usually have the same design of alcove models, even in dimensions. A typical tub of this accessible style is 60 inches long and 30 inches wide.
But as mentioned, their heights are vastly different.
While we have known that average-sized alcove tubs are 18 inches high, a typical walk-in tub has a height of 30 inches. This depth will allow you to submerge your body comfortably while sitting on the built-in bench.
With built-in water jets, whirlpool tubs help massage your muscles, providing the most enjoyable experience you can find in any house.

Though they seem to be larger than other models, there are plenty of products on the market that come with the size of a standard alcove tub.
They mostly are 60 inches in length and 32 inches in width. A typical model also has the same height as a mid-sized tub – 18 inches while the walk-in variant might be as tall as 23 inches.
From the standard bathtub dimensions of every type of tub above, we hope at least now you have had a general idea about whether your preferred style will fit into your bathroom. And if it doesn’t, you will have an easier time finding an alternative.
