At 6' long nearly every alcove installation bath is at least 36" wide. Even at 5' there are a lot of baths in the 36-42" range. Go to kohler and search on bathtubs then length then 3 wall alcove and you will have many choices. If you're looking for an all in one pop in shower module it might be a lot tougher to find because those are designed to be inexpensive - a wider tub is a bit of a luxury thing.

I know this thread is a couple of years old but after a little Googling I found that this question has not been answered very well anywhere. What I have discovered is that you are not going to be presented with many soaking tub/shower combination photos in magazines or books. They all tend to focus on 'idealized' situations where there is ample room for both a soaking tub and a detached shower. But combining a soaking tub & shower is very possible. Here are a couple of ways it can be done. a. The free standing tub (e.g. clawfoot tub) with a wraparound shower curtain on a circular shower curtain rod. This is probably the simplest way to achieve a soaking tub/ standing shower combo. And if you do not car for the 'clawfoot' design there are many new free standing tubs that have bases other than clawed feet. Some are very elegant looking. b. A 'drop in' tub with square corners where tiled walls can be brought right down to the lip of the tub so that there is are no flat, horizontal surfaces where standing water from a shower can accumulate. This might require bringing the wall a bit closer to the tub. No problem. It can be done. Say your space is 80 inches and your soaking tub is only 70 inches long. Bring one wall 10 inched closer to the end of the tub (or both walls 5 inches closer) and create cubby holes (shelves) for towels in the walled area. c. Install a drop in soaking tub in the typical fashion, but include a circular shower curtain rod above it, and place the shower head above the center of the tub, or even hang it directly above the tub pointing straight down from the ceiling. This is actually the design I am considering. I may be a bit unconventional but who cares about convention if it is functional, serves your purposes and it installed in such a way that it looks visually appealing. If you place a cute ring to hold the shower curtain away from the tub when not in use and purchase a pretty looking circular shower curtain ring you could have yourself a real winning design. You could even place a horizontal beam covered with tile along the ceiling that would hide the shower curtain ring. d. A wet design. Either a claw foot style tub or drop in tub can be coupled with an overhead shower with no shower curtain whatsoever if you tile and slope the floor toward a floor drain. If using a drop in tub, slightly angle the horizontal tiled surfaces surrounding the tub so there is no free standing water, so that any water runs off onto the floor and into the floor drain. There is no reason why this cannot be done. After all, the floors of showers are slightly sloped, tiled, horizontal surfaces! Just use some creativity and do what you want. There are many ways to accomplish a soaking tub/standing shower combination! Of course you don't want to do anything too weird of it might affect your resale value. But if you use common sense you can definitely come up with a wonderful design. Don't let other people tell you what to do!! Note: If stepping in and out of a tall soaking tub seems unpractical for daily use, considering building 2 or 3 tiled steps up to your tub. problem solved. For extra safety a chrome grap bar or two and be affixed to the walls. Never a bad idea in any shower or tub anyway! -MyDogBurt

Just a follow-up. Mom didn't like the look of the walk-in tub. It also has a distinct disadvantage. You have to be in the tub to run the water because the level of sitting is so high. You also have to wait until the water drains out of the tub to open the door before you can get out. They also have some that can be used as a shower in addition to tub. This was an advantage because the water would continually drain out while showering, but could sit down if needed to.

If I may followup on my own posting, if we're going to have a tub it's going to be one my 6'3" body will fit in. Another reason to go large.
