I am replacing an alcove bathtub in my teenagers bathroom. It is the only bathtub in our home. The dimensions will be 30x60. The current tub is a bit less than 9 inches of water depth. My kids mostly use the shower, but I would like to replace it with a deeper tub (at least 12 inches of water depth) so taking a bath is an option - but I realize that will mean a higher "step" to get in the shower. (We are a pretty tall family - so taking a bath in the current bathtub doesn't work well). Any advice on tub option? Anyone regret getting a "soaking" tub that is used for a shower as well? Thank you!
