Size and Capacity

First and foremost, ensure that the portable bathtub you choose is large enough to accommodate adults comfortably. Measure the available space in your bathroom and consider the height and length of the person who will be using it the most. Look for bathtubs that have a generous depth and width to provide a comfortable soaking experience.

Material and Durability

Some models may come with additional accessories, such as cup holders or trays, to enhance your bathing experience.

Drainage System

A reliable drainage system makes it easy to empty the portable bathtub after use. Check for a sturdy drain plug and, if possible, a hose attachment for convenient and mess-free water disposal.
