They made a warm floor in the bathroom. At first they wanted to put a mat, but there you need 80 cm in width, and the mats are only 50 cm. The Leto store offered a thin cable, even calculated everything and intelligently told what was what. As a result, everything was brought in a set, nothing had to be bought. My husband packed it himself and called the store a couple more times, consulted. Everything is working fine now. Thanks for the excellent service, and the price is relatively low.
