What are the measurements of a bathtub inside outside?

Published in Bathtub Dimensions 2 mins read

Typical bathtub measurements encompass both the overall outside dimensions like length and width, and interior dimensions crucial for bathing comfort such as water depth. Based on common standards, these measurements vary depending on the bathtub's size and style, particularly for popular freestanding models.

Common Bathtub Dimensions

Understanding bathtub measurements involves looking at both the exterior footprint for planning purposes and the interior space for usability. The provided reference highlights dimensions for freestanding bathtubs, giving typical outside length and width, along with the inside water depth.

Here are common measurements for freestanding bathtubs as referenced:

Bathtub Type Outside Length Outside Width Inside Water Depth
Common/Standard 60 inches (5 ft) 30 inches (2.5 ft) 19 inches (1.89 ft)
Small Freestanding 55 inches (4.58 ft) 27 inches (2.25 ft) 15 inches (1.25 ft)

These figures provide a clear picture of standard sizing:

  • Outside Length and Width: These represent the maximum exterior measurements of the bathtub, essential for ensuring the tub fits within the planned space in your bathroom.
  • Inside Water Depth: This indicates the depth of the water you can comfortably fill the tub, which is a key factor for a deep soak. Note that the overall inside length and width (the actual bathing area) will be slightly smaller than the outside dimensions due to the thickness of the tub walls.

While these are standard measurements for freestanding tubs, other types like alcove, drop-in, or corner bathtubs will have different typical dimensions designed to fit specific installation types. Large soaking tubs or custom designs can also vary significantly from these standard sizes. Always verify the exact specifications from the manufacturer when planning your bathroom layout.
