Mosaics
Mosaics are expensive but make your pool more unique. If you buy the mosaic yourself online you can press the price a lot. There are some concern about buying mosaic yourself: you can't check the the quality or how they really look, and the tile company maybe don't agree on putting up mosaic that you bought.
Make sure you know what size you want on the mosaic. A piece of mosaic can sound big to you but if you have a big pool it could still look too small. If you wonder how big a piece of mosaic is comparing to your pool, you can cut out a rough figure in construction paper and lay on the bottom of the pool/ground, where you want the mosaic to be. Does it look big enough or do you need to order a bigger one?
Mosaic can be put anywhere in your pool; on the walls, benches, steps or floor. Some interior companies don't want to put mosaic on the bottom of the pool because the interior crew may step on it, and they are wearing shoes with nails under to keep a good grip.
It requires bigger mosaic if you put the mosaic on the bottom of your pool. Some people like to have mosaics on the steps so they easier can see where the steps are.
What color you chose on your mosaic is also important. If the color is too close to the interior you will not be able to see the mosaic.
Doesn't it look cool with the gecko climbing up the wall? But sometimes it doesn't really turn out the way you imaging it.
Do you have a lot of mosaic and are afraid not to remember where you and your family decide to put them? Hold the mosaic on the spot you want it and outline it, or take picture of the pool with the mosaic lying where you want them. This works of cause only if you have bought the mosaic ahead.
