Is a 12 mil wear layer enough for a kitchen?

Yes for normal residential use. 12 mil handles daily foot traffic, pet claws and dropped utensils, and the UV-cured coating adds scratch resistance. Very heavy commercial traffic is where 20 mil planks pull ahead.

Do I need underlayment with the attached EVA pad?

No. The 1mm EVA pad is already bonded to the plank, so you lay it as a floating floor over a flat, clean subfloor. Skip foam underlayment; it can make the click joints flex.

How does it compare with glue-down vinyl plank?

It floats and clicks together instead of gluing down, so removal is easier and install is faster. Glue-down is thinner and quieter underfoot but harder to replace and needs adhesive and cure time.

Can it go in a bathroom?

The SPC core and vinyl surface resist moisture, so it works in baths and laundry rooms. Standing water at tub edges and leaks still need to be wiped up, and the perimeter needs an expansion gap.

Planks only, with the EVA pad pre-attached. You supply the underlayment-free subfloor prep, spacers, a tapping block and a pull bar for the Uniclic joints.

How does it compare with the Hemingway 20 mil version?

The 20 mil plank carries a thicker wear layer for heavier traffic and longer commercial life. This 12 mil version is the lighter-duty, easier-on-the-budget pick for homes.
