This guide will let you know how to make a pool on the second floor of your house.
You will first need to make a two-block high rectangular structure on the ground and make a pool at the center.
After that, use wooden panels around the swimming pool and place fences to cover the pool’s edge.
Cover the center part with blue carpets. It will look like a pool now.
But you cannot swim in this pool. Remove one wall of the rectangle and make a flat roof the same as the swimming pool’s dimensions. Then drag it up to the height of the rectangle.
Cover the rectangle, and now you will be able to get into the swimming pool.
