Seeking: 5' Rectangular Tub w/ Tile Flange, No Apron. Suggestions?

I'm looking for a 5' Tub for a 3 wall alcove installation. I would like to find a nice modern rectangular shape with as few as possible interior ledges. Also trying to keep the cost down.

I like the Kohler K-1123 but they don't offer it with tile flange unless it has the integrated apron and specs say not to install it in an alcove.

I also like the Kohler K-850 which says it can be installed in a 3 wall alcove, but seems to use a tiling-in bead for doing so. Also not looking for cast iron and the price is a little higher than I'd like.

The Hydro Systems Lacey looks great and is available with tile flange, but requires mortar bed setting and price is lower than the K-805 but still a bit high.

I was also considering using the K-1123 with the Schluter®-DILEX-AS .

But if I can find a nice looking rectangular shaped tub with flange for a good price I would much prefer that route.

Suggestions? Thanks.

If you are looking for anything other that a regular 5' tub with front apron, 3 sided tile flange.....then you are in what I call the "foo-foo" category, and get out the checkbook!
