Every bathtub is unique, and the right one for you depends on your preferences and the space available in your bathroom.

While the most common bathtub size is typically 60 inches in length, 30 inches in width, and 14 to 16 inches in height (with an apron at the front), bathtubs are available in a wide variety of shapes and sizes.

When choosing the perfect tub for your bathroom, consider factors like size, installation requirements, and additional features. Looking for more design ideas? Sign up for our free daily newsletter to discover the latest decor trends, expert tips, and much more!

1. Alcove Bathtubs

An alcove bathtub is designed to fit into a space enclosed by three walls, making it a practical choice for small or standard-sized bathrooms. These tubs typically feature a finished front panel, known as an apron, while the two side ends and the back remain unfinished, as the surrounding walls cover them. Alcove bathtubs generally range in size from 5 to 6 feet in length and 30 to 36 inches in width, providing various options to suit different bathroom layouts.

2. Soaker Tubs

Soaker tubs are designed for deep relaxation, allowing you to fully submerge yourself in water or recline with a bath pillow. These tubs are typically at least 20 inches deep and can go up to 24 inches. Standard soaking tubs range from 60 to 72 inches in length and 30 to 40 inches in width, but compact options are also available. Small soaking tubs, for instance, measure around 48 inches by 28 inches.

3. Freestanding Bathtubs

Freestanding bathtubs range in style from classic clawfoot designs to sleek, modern pedestal tubs. Many freestanding tubs also double as soaker tubs. They generally measure 55 to 72 inches in length, 27 to 32 inches in width, and 15 to 20 inches in depth. When planning the placement of a freestanding tub, it’s recommended to leave an extra 3 inches of space at the ends and 4 inches between the tub and the nearest wall.

4. Drop-In Bathtubs

Drop-in bathtubs are designed to fit into a custom-built deck, with the surrounding surfaces finished in tile or another material of your choice. Unlike other tubs, drop-in models do not have any factory-finished sides and are installed by placing the tub into a cutout within the deck, similar to how a drop-in sink is fitted into a countertop. These tubs vary in size, typically ranging from 45 to 72 inches in length, 30 to 32 inches in width, and 14 to 20 inches in depth.

5. Oversized Tubs

Oversized tubs are perfect for those seeking a spa-like experience or a tub that can accommodate more than one person. These tubs are typically over 70 inches in length and have a soaking depth of at least 16 inches. For an ultra-deep soak, some tubs reach depths of 32 to 38 inches, though a height of 25 to 27 inches is often sufficient for a comfortable soak.

6. Whirlpool Bathtubs

Whirlpool tubs, often larger than standard tubs, combine functionality with luxury. Despite their size, they are available in alcove-ready designs and drop-in styles, making them a versatile choice for various bathroom layouts. The thin acrylic shell conceals the jets and pumps tubing while maximizing interior space. Whirlpool tubs usually measure between 60 and 72 inches in length, up to 36 inches in width, and 18 to 23 inches in height.

7. Oval Bathtubs

Oval bathtubs are available in both drop-in and freestanding models. While they may appear more spacious, their extra size comes primarily from increased width rather than length. Garden tubs, which are taller soaking tubs, fall under this category. Compared to a standard 60-inch alcove tub, oval bathtubs can be up to 6 inches wider.

8. Corner Bathtubs

Corner bathtubs are an excellent option for larger primary bathrooms, providing a comfortable space for soaking and lounging. These tubs typically occupy a square-shaped footprint, with one corner cut off, making them more space-efficient than their triangular counterparts.

9. Long Bathtubs

Long bathtubs are ideal for taller or larger bathers or for those who prefer a more spacious soak. These tubs are typically a foot longer and a few inches wider than standard alcove tubs, offering more room to stretch out. They are also suitable for two-person use.

How to Choose the Right Bathtub Size

Selecting the perfect bathtub depends on several factors, including the size of your bathroom, your aesthetic preferences, your budget, and your plumbing setup. Here's what to consider:

1. Bathroom Space: Measure your space carefully to ensure the bathtub will fit.

2. Bathroom Style: Choose a tub material that complements your bathroom's aesthetic. Options include acrylic (alcove, drop-in, corner, whirlpool), copper, concrete, cast iron (freestanding), or natural materials like wood or stone (soaker tubs).

3. Budget: Smaller tubs, such as standard alcove models, are more affordable, ranging from $1,000 to $5,000.

4. Uses: For a luxurious, spa-like experience, choose soaking, whirlpool, or oversized tubs.

5. Installation: Consider your existing plumbing setup to determine which tubs are feasible.
