Plastic 

Plastic sandboxes are relatively inexpensive and portable.  They come in all sorts of shapes and sizes to accommodate your child (try turtles, seashells, ladybugs, you name it).  They also are easy to maintain and clean up with form fitting lids.  Their biggest downfall is that they can get easily worn in warmer, sunnier climates, which causes them to fade and become brittle.

Elevated or Sand Table  

An elevated sandbox or sand table sits at your child's waist height and often has separate compartments for sand, water and toys.  These are great for minimizing mess since kids only get sandy hands instead of sandy bodies, and they can even be used inside if you place a plastic sheet beneath them (great for not-so-nice weather).  Sand tables can accommodate a larger number of children that other sandbox models, and they are multifunctional--place on the lid to convert one to a normal play table.

Timber 

Timber sandboxes are largely available in square and hexagonal shapes, though they come in various sizes to accommodate several children at one time. Look for boxes made of spruce  or red cedar , as they are the most sturdy and weather resistant.  Pine  is usually a decent, cheaper alternative, but you have to make sure it isn't treated with any dangerous chemicals.  Plastic-timber composite s are also making their way onto the sandbox scene for a higher price than most, offering increased durability and relieving the threat of splinters.

DIY 

There are a bunch of kits  out there that provide you with the instructions and materials to build your own sandbox, but you usually have to start out with a little bit of woodworking knowledge.  You can also make your own sandbox on a smaller scale using a large plastic storage bin and sand from your local hobby shop.
