Regarding the hot/cold on the delta allora, I am right handed and like my control mounted on the right because that's the hand I reach with to turn it on. It's not really hard to get used to the front to back for hot and cold, there are also teeny little blue and red indicators to remind you which is which. If I can get DH to get under the sink to unscrew the mount, I would like to position that handle just a bit forward (it can spin in any direction) so when on full hot, it isn't so close to my windowsill. That's my only complaint and it was an install issue. I have heard many people complain over splashing on all the gooseneck faucets, not just the delta but it is a really easy fix....I got used to using less pressure (bonus is it saves water) pretty quickly. It doesn't splash at all in stream, only spray and then, only when turned up. I really only use my spray for sink cleaning and I always have the hose extended and the head sweeping around the sides...no spray even on high. My old side spray used to splash if it were turned up and held up high...I think it's the nature of the beast. I have a kindred undermount stainless sink, single bowl. The bowl insides are 27.5 x 17 and I find it a good fit. When I first opened my faucet, my first impression was holy smokes, it's toooooooo huge. Not so. I love love love it. In fact, my faucet and single bowl undermount sink are my favorite things in the kitchen.

I don't think the Highbridge is offered anymore without the enameled apron although they still may be in stock with a number of suppliers. The apron covers only the middle part of the front, so you have to custom build something to cover the front at each end (storage or tile) or cover the whole front with a tiled apron. Its essentially styled like a drop in tub but built as an alcove tub with flanges. This tub will offer the deepest bathing. The Mendota differs from the Bellwether also in that the Bellwether has a flattish rim around the top that you can set down things at least temporarily, but the Mendota has a thin and beveled rim, which probably makes the interior a bit wider, but I don't think you could put a shampoo bottle down or sit on the edge of this tub comfortably. The other option is the Kohler Dynametric. I just bought the Bellwether 30x60 without the angled front but it is not installed yet.

We have the Maax Rubix 60x32. It feels very solid, and roomy. Make sure your installer puts a mortar bed underneath for support (per manufacturer's directions). Our contractors attempted to omit that step.

We replaced an older Underscore overmount that was improperly being used for a tub/shower combo with a newer Underscore alcove tub, no apron K-1121-R-0. The 30” width is no problem, I would be more concerned about her height as far as ability to get out of the tub as its somewhat deep (great for soaking!). I am 6’ 260lbs and feel the tub is still roomy. We did have problems ordering the tub so I recommend ordering before you start construction. We got a left facing tub first, the second tub was cracked, the third one was fine. Ordered through Home Depot first and then Amazon, returns were all handled just fine. Photo is after tile but before the glass swinging splash panel was installed.
