Yes, that is a sunken-in tub...very deep. Visions of "I've fallen and I can't get up" kept running through my head the first time I saw it. I actually attempted to get in, and let me tell you, I don't know how anybody would want to shower/bathe in that monstrosity and attempt to get out of it wet.
Ever since we were married, we had really bad showers. Too small, not enough water coming out, nozzle head at the level of your chest, etc. Well, no more. We got rid of the sunken in shower; my wonderful little brother mudded in a shower pan (basically made it from scratch) and I have spent the last month tiling...it wouldn't have taken so long if I was without kids, but Paula (mother-in-law) was gracious enough to watch kids while I was finishing up. These pictures don't really show it, but the shower head is almost to the ceiling...yes, even a tall basketball player could easily shower in it. We put in two shower heads, and I can hardly wait to take my first shower in it!
I still have a little bit more tiling to do, but the bulk of tiling is done. I told Brian that when we fix the other shower (not sunken-in, but chest level again) we are just going to put in a pedestal bathtub like such...no tile!
