Embarking on a bathroom renovation or looking to replace an old bathtub? Understanding the standard old bathtub size is crucial for ensuring a seamless replacement process. This guide delves into the dimensions of old bathtubs, their types, and how to measure for a perfect fit.
Old bathtubs, particularly those installed before the 1980s, typically come in two standard sizes: 60-inch and 66-inch. These sizes refer to the length of the bathtub, not including the apron or surround. The width usually ranges between 30 to 36 inches, with a depth of around 16 to 18 inches.
Sixty-inch bathtubs are the most common size found in older homes. They are often paired with a 32-inch wide surround, making the total width around 92 inches. This size is well-suited for smaller bathrooms as it saves space without compromising comfort.

Sixty-six-inch bathtubs offer more legroom and are ideal for taller individuals. They usually come with a 36-inch wide surround, resulting in a total width of about 102 inches. This size is perfect for larger bathrooms or master en-suites.
Before purchasing a new bathtub, it's essential to measure the space accurately. Here's what you need to consider:
| Dimension | Measurement |
|---|---|
| Length | Measure from the wall or existing bathtub to the opposite wall or obstruction. Ensure the new bathtub will fit comfortably within this space. |
| Width | Measure the width of the existing bathtub or the space where the new bathtub will be installed. This will help you determine if a 30-inch or 36-inch wide bathtub will fit. |
| Height | Measure the height of the existing bathtub or the space where the new bathtub will be installed. This will help you determine if a standard-depth or deep-soaking bathtub will fit. |
Always round up your measurements to ensure a perfect fit. If you're unsure about any aspect of the measurement process, consult a professional plumber or bathroom designer.

In the world of bathroom renovations, understanding old bathtub sizes is key to a successful and stress-free replacement process. By familiarizing yourself with standard sizes, types, and measurement techniques, you'll be well-equipped to transform your bathroom into a haven of comfort and style.
