What should you know about standard bathtub dimensions? Your typical bathroom needs to incorporate so many elements. And most of these components are necessary.

We cannot leave one and concentrate on another. Moreover, each item takes up a particular area. For example, the toilet, shelves, bathtub, and vanity, which are larger in size, can use so much space.

Now, with every square foot at a premium, space optimization becomes a necessity. And this is when we need to consider sizes, especially for the bigger units. Understanding standard bathtub dimensions is another step toward ensuring a properly planned, efficient bathroom layout.

Your bathtub or tub-shower-combination should fit inside the bathroom so that it does not look out of place. For example, if your tub is too big, it might leave only a few inches for you to maneuver between the sink, toilet, and shower areas. Again, if it’s too small, your entire bathroom might seem as if it’s swimming in space. Hence, knowing about the correct bathtub dimensions is necessary.

What are the standard bathtub sizes?

Standard dimensions are meant to give you a rough estimate of the bathtub sizes. A regular wall-to-wall tub would approximately measure 60 inches in length and 30-32 inches in width. However, these figures can widely vary, depending on the shape and type of bathtub you are planning to buy.

Remember that there is no single standard tub size. Since there’s a wide range of bathtubs available on the market today, a homeowner is spoilt for choice!  

Different categories of tubs include walk-in tubs, soaking tubs, drop-in bathtubs, corner tubs, and freestanding bathtubs, to name a few. Therefore, below, we have described the standard bathtub dimensions (lengths, widths, and heights) for some of the common varieties. Go through them and decide which unit would be the best fit for your existing bathroom.

Keep in mind that a standard size bathtub costs anywhere between $200 and $14,000 depending on the bathtub material, quality and design.

Alcove Bathtubs

Alcove bathtubs are a good idea for small and narrow bathrooms. It is bounded by three walls and is installed along the width of the room. Hence, the longer walls serve as the ends and the back wall forms one side.

But in the case of large bathrooms, alcoves may not be a good idea. Since the walls are not close enough to create the alcove, it might have to be placed along the length, with a custom wall built on one end of the tub.

The average tub size for alcove bathtubs: 48-72 inches long and 15-20 inches wide.

Small Bathtubs

With large spaces gradually becoming a luxury, homeowners usually have to opt for small bathrooms. In such cases, small bathtubs are the go-to options. If space is extra-cramped, then you might just ditch the idea of a tub and opt for a shower instead. However, if you really want a bathtub then you can go for one with a smaller size.

The average tub size for small bathtubs: 54 inches long, 30 inches wide, and 15 inches high.

I didn’t realize that soaking tubs were deeper than standard tubs. I really appreciate you explaining all of these different tub types so that I have a better idea of what may be the most enjoyable for us as we look at getting a tub in the future. It’s important for us to know what options are out there so that we can pick something that we will be content with for a long time, since a tub can be a bit of an investment
