How to measure for a standard bath

Accurate measurements are key to ensuring a perfect fit when installing a standard bath. Here are some essential tips:

  1. Don’t just measure the existing tub if you have one. Measure the space around where you expect your new tub to be placed. 
  2. Take note of the location of the plumbing fixtures in your bathroom. This will help you determine where the drain and water supply lines are, ensuring that your new tub aligns with the existing plumbing.
  3. Measure the length, width, and height of the area where the bath will be installed. Ensure accurate measurements by using a tape measure and recording the dimensions carefully.
  4. Consider the basin area of the tub, which is the space where you will be sitting or lying. Make sure it provides enough room for comfortable bathing.
  5. Take note of the desired water depth in your bath. Measure the depth of the tub to ensure it meets your comfort requirements.
  6. Check the capacity and weight of the standard bath you are considering. Ensure that your bathroom floor can support the tub’s weight when filled with water.
