we are redoing our bathroom and i want to make sure the tub is deep enough for a bath. THe one upsairs is a standard size I thinkg, about 13.5 deep. Wife finds this is too shallow for her, the water level is never high enough, once the water rises to the level of the safety drain, that is it. She has to keep legs as straight as possible, sinking down to keep under the water.
What is the standard size and then what is the next size deeper?
Thanks in advance
