I would think so. I got the Kohler Greek tub and installed it in an alcove. Kohler sells a tile-in bead kit which I bought. We ended up using something else that my contractor bought but was the same idea.

If it's an acrylic tub, the short answer is "technically yes". If it's a cast iron, then no. You can't glue plastic to cast iron with any success. The long answer is that that isn't a tub that's suited to being used as a shower, regardless of if a tile flange is attached. The large deck area will funnel water onto the adjacent floor rather than into the tub. Tubs that are designed for use as a tub/shower combo do not have any deck area for water to accumulate. They are designed for the flange to fit against the wall, and the wall of the tub to be directly below it to funnel the overspray back into the tub.

I took a lot of long showers in high school in an original pink Cinderella tub, with no water on the floor.

Pal, did you see the link I posted in Kitchens? You can get an original white Cinderella with flanges on three sides.

I think I have a plan worked out where I can use the Mayflower tub in a corner installation, without the extra side enclosed alcove style.

The existing situation is a small back-to back full bath/powder room set up where the powder room was jerry rigged into a three quarter that is not code compliant I don't think.

The plan is to redo both baths but there is no way to expand (at least in one direction) so gaining space for the 3/4 involves stealing a few inches from the full bath.

This tub provides the answer, I think, and it would be appropriate because it's a mid-century house. Not being able to add a flange actually made me look at both bathrooms differently.
