OK...vinyl floors are MADE for entrances, bathrooms and laundry rooms. Why would you exclude it from these spaces? If you use vinyl you might as well put it EVERYWHERE. It is build to deal with these areas. It is different from laminate. Even if they LOOK the same they are VERY different products.

If you want a different LOOK in the mudroom/bath/laundry then you can simply switch the SPC product (aka vinyl) to look different. The thickness, etc will be identical. It is a SUPER easy product to do more things with.

Remember: SPC products normally do not like acoustic underlay. It can be done but the underpad product must be specifically designed for these floors.

Engineered hardwood is a bit trickier. The Biyork products offer SUPER thin wear layers...and ONE wear layer that is 'decent'.

Everything is manufactured in China. I would trust the SPC 6 or 7 from them...but the engineered is a bit risky for me.

And there's a new SPC product appearing on the market. SPC core like LVP but with a 1.2mm layer of hardwood veneer instead of the printed LVP layer that looks like wood. It can have a 20mil aluminum oxide clearcoat like many vinyl products with a long warranty. $4-$6 a square foot. Made in China or Vietnam. I'd find this a more authentic looking floor because of the natural variability of wood veneer.

More- Aqua-allira. Waterproof engineered wood.

Dan1888 Hallmark Regatta Collection Flooring is the same a thin veneer wood with padding $6/sft.

@John Creek do you have any installation photo of the Regretta? I'm actually thinking of intalling the Hallmark Leeward Regretta in our kitchen and then the Hallmark Organic 567 in Gunpowder in the rest of the house. The colors and look are almost identical (I have sample boards of each), although the texture is a little different since the Organic 567 has more scrapes and texture. But the Regretta being waterproof, seemed a better fit in our kitchen. The living room is a step down, so the transition is not a big deal in there, but we do have to other rooms (dining and office) that I would like to keep the Oragancic 567 as well, but it flows into the kitchen via a doorway, so I might just keep it all the Regretta, even though I love the look of the Orangic 567. The 567 will go up the stairs as well (off the dining room). I'd love to see photos of the Regretta in a real house. There are very few photos out there. Post some if you have any. Any info would be helpful. Thanks!

If you want to increase the acoustic separation between floors, in addition to an underlayement, suspend the ceiling with resileint channels or on channels attached with acoustic isolation clips.
