Looking for kids’ swimming lessons? Look no further as our Sensational Swim School is the largest swim school in Singapore. With over 320+ fully certified instructors (教练), we can conduct affordable swimming lessons at your preferred location, schedule and budgets.

Every single one of the students learns to swim in an enjoyable environment, but safety is our priority. We make sure that our kids know how to be safe in the water by providing them with all the basic skills they need.

At Sensational Swim School our kids’ swimming lessons follow a progressive method that makes learning fun, not stressful or fearless. With private lessons our instructors go at your child’s speed, progressing them only when they’re ready.

We’re so confident in our methods that we offer a Learn-to-Swim Guarantee in all of our private swimming lessons for children. If your child can’t swim back to the pool wall after 12 lessons, you’ll get up to four more lessons for free.

Parents are busy, and often difficult to fit their child’s swimming lessons into their schedule. That’s why our instructors come to you, holding lessons at a time and pool that’s convenient for you.

Our swim instructors are highly experienced and have at least two years teaching, CPR and First Aid Certified, and many are also Red Cross lifeguard or Water Safety Instructor certified.
