Sablikova claimed her third gold of the week in the women's 5,000m, winning by an astounding margin of 40 seconds and smashing the track record.
"I am really satisfied," the Czech speedster said. "I think it has been very good preparation for the next part of the season.
"My results here were really good. I have enjoyed the championships very much, the atmosphere and the town."
Norway's Camilla Farestveit took silver and Kazakh skater Yelena Urvantseva bronze.
Natalia Czerwonka provided cheer for the home crowd with victory in a women's 1,000m field missing Sablikova. Luiza Zlotkowska, also of Poland, took silver while Tatyana Sokirko from Kazakhstan claimed bronze.
"There were much better conditions today," Czerwonka said. "It is great we have won more medals for Poland. Martina was not here, so it was much easier to compete for gold."
In the only men's race of the day, Norwegian Martin Bjertnes won the 10,000m, beating his personal best by 17 seconds.
Poland's Sebastian Druszkiewicz came in second after fading midway through the race, with Czech Peter Kulma taking bronze.
