Friend's fab new kitchen extension has Amtico over wet uf heating. Looks lovely but... she now makes her DC always wear indoor shoes - says it's pretty hard to walk on all day. (Concrete floor with uf heating pipes inlaid). Now wobbling about my own new kitchen plans as I wanted the same flooring. Help! Any thoughts on a kitchen floor with uf heating that won't feel so hard underfoot or is it the price to pay for toasty toes? TIA.
