If your tub rail is straight without any curve in the design; selecting the correct tub to shower kit is quite easy. However, if your tub design contains a curve or an offset across the front of the tub, the insert will NOT curve along those lines. Furthermore, you will need to include the curve into your rail measurement to ensure the correct tub to shower kit is ordered. So, be sure to follow our detailed instructions here for selecting the correct to shower kit.
Seems like this is a common question when searching for tub to shower kits, yet it isn’t one we can easily answer. First of all, you need to know the height of your individual tub. Then, subtract the cut out dimension height of the correct shower kit for your tub from the total height of your actual tub. Finally, this should give you an approximate finished step height.
As an example, your tub skirt measures 12″ from the floor to the rail. You order the medium kit which has cut out height of 8″. Therefore, your finished step over height should be approximately 4″.
Yet, if you need the step over height to be lower than 4″, you might consider purchasing the large kit instead. Since the large kit has a cut out height of 10″, your step over height would be closer to 2″. The finished look will not be as pretty. Most likely, you will have more of the insert protruding inside, outside and/or above the tub. As a result, it will allow you to lower the height of the step.
