Hannah Miley, Jemma Lowe and Michael Jamieson took Great Britain's final medal haul from the European Short Course Championships in Poland to nine.
Lowe added to the 200m butterfly silver she won on Thursday with the same result in the 100m butterfly.
Miley took silver in the 400m individual medley after bronze in the 200m event, while Jamieson was third in the 200m breaststroke.
Lowe said: "Getting silver in the 200m definitely gave me confidence."
Denmark's Jeanette Ottesen finished 0.45 seconds ahead but Lowe broke her own three-year old Welsh record in 56.67 seconds.
She added: "I really enjoyed it. I wasn't expecting that time though - I haven't done a best in that event for three years.
"I knew she [Ottesen] would go out fast so I just swam a controlled race for the first 75m then put my head down and finished hard. The last 25m really hurt but I'm really pleased with that."
Miley was delighted to have finished her campaign with another medal.
Spain's short course specialist Mireia Belmonte Garcia touched 1.51 seconds ahead of the Scot for the title but, having not tapered [reduced training times] for the event, Miley insisted her silver medal in four minutes 26.06 seconds was an ideal way to close her meet.
"It's always hard to swim on the last day but I'm really happy with that, it was a great race." Miley said.
Miley's Scottish compatriot Jamieson also had to wait until the final day for his favourite event but his patience paid off as he stormed to his first honours at senior European level.
The Commonwealth silver medallist, who finished eighth in the 100m Breaststroke earlier in the week, set a personal best in the heats before breaking team-mate Kris Gilchrist's British record in the final as he touched in 2:03.77.
Elsewhere, Jamieson's training partner Andrew Willis broke the oldest English short course record on the books, toppling double Olympic medallist Nick Gillingham's time from 1993 with his effort of 2:06.02 in the heats on his way to reaching the 200m breaststroke final, where he finished seventh, while Antony James was also seventh in the 50m butterfly.
Teenager Rebecca Turner finished a creditable fourth in the 200m freestyle with Anne Bochmann ninth while Amy Smith was sixth in the 50m freestyle.
