Koukalová made her Grand Slam debut at the 2003 Australian Open, defeating fellow qualifier and Grand Slam debutante Maria Sharapova in the first round before going on to upset sixth-seed Monica Seles in the second round. Koukalová's run ended in the third round.
In January 2006, she played comeback player Martina Hingis, at the WTA tournament in Gold Coast, Queensland, Australia, where she lost in the second round. Koukalová was seeded 29th at the 2006 Australian Open, but lost in the first round to Ekaterina Bychkova. In that year, Koukalová had ten first-round losses in singles and failed to win a doubles match.
In 2008, Koukalová reached the final of the inaugural Cachantun Cup in Chile. She played the top seed Flavia Pennetta, but was forced to retire due to a sprained ankle. This also forced her to withdraw from the next tournament in Bogotá, where she had made the quarterfinals in 2007.
Koukalová's biggest win came at the 2009 Andalucia Tennis Experience in Marbella, Spain. She defeated world number 1 and ten-time Grand Slam champion Serena Williams in three sets. Williams was also her first round opponent at the 2009 French Open, where Zakopalová lost.
In the first round of the 2010 Polsat Warsaw Open, Koukalová caused a big upset by defeating fourth seed and world number 14 Marion Bartoli. She was then defeated by world number 205 Gréta Arn in the second round.
At the 2010 Wimbledon Championships, Koukalová advanced to the fourth round for the first time at a Grand Slam. She scored upset wins over 18th seed Aravane Rezaï and tenth seed Flavia Pennetta, before falling to qualifier Kaia Kanepi.
Koukalová made the final at the 2010 e-Boks Danish Open, where she lost to then world number 3 Caroline Wozniacki. Koukalová defeated Rossana de los Rios, Tatjana Malek, Sorana Cîrstea, and Li Na en route to the final. After this tournament, she could not match her performance as she went on to do poorly in her last four tournaments, only advancing to the second round at the 2010 Generali Ladies Linz, where she lost to Patty Schnyder.
Koukalová started her 2011 season at the Hobart International, after having to withdraw from the Brisbane International. She made the semifinals in Hobart, upsetting the top seeded Marion Bartoli in the quarterfinals, before falling to her doubles partner Jarmila Groth.
At the 2011 Australian Open, Koukalová defeated American Melanie Oudin in three sets in the first round, before falling to fellow Czech Lucie Šafářová in three sets in the second round. This was Koukalová's first victory at the Australian Open since 2003.
After her defeat at Roland Garros, Koukalová traveled to Copenhagen to defend her finalist points from the year before. Seeded second, she was upset in the first round by German Kathrin Wörle.
Koukalová then returned to the site of her greatest Grand Slam accomplishment, Wimbledon. Unseeded, she came from a set down to defeat British wildcard Emily Webley-Smith in the first round. In the second round, she avenged her Australian Open loss by upsetting 31st seed Lucie Šafářová in three sets. In the third round, Koukalová fell to eventual finalist Maria Sharapova.
After Wimbledon, Koukalová made the semifinals in Budapest, where she lost to the eventual champion Roberta Vinci, and then made the quarterfinals in Palermo, where she lost to eventual finalist Polona Hercog.
On 6 June 2006, Klára married Czech footballer Jan Zakopal, but they divorced in January 2014. From June 2006 to March 2014, she used her married name Zakopalová while competing, switching back to Koukalová in April 2014.
