I have an Expanse and was going to recommend that, but it won't work for you. I just love the additional space. I also use it 99 percent of the time for showers, which was why I wanted a wider tub. I am so happy with it. The only downside is that it is hard to clean the far side of it because it's a long reach from outside the curve. I usually just get in the tub to clean it. That is a minor nit-pick. Good luck with your search.

One word of advice - since this will be used for showers most of the time, make sure to pay attention to the basin area bottom numbers. This will be the room you have to stand in. With the way so many tubs have cutouts and ledges and slanted back, etc., you need to know how much room is actually on the bottom and not how much room the tub takes up in the room.

Windward:
Basin area, bottom 55" x 23-1/4"
Basin area, top 64" x 32"

Inside dimensions are most important. Check out Hydrosystems. I believe you can get the Lacey in a long size and multiple widths, and you can customize it with skirted sides (or not) and tile flanges one or more sides.

Thanks for the helpful reminder to pay attention to the inside dimensions!

Kevin, I'm putting the Lacey on my list. I love the way Hydrosystems makes it easy to compare the dimensions of the different Lacey models on their website.
