Custom made sandbox bench

6ftx6ft sandbox. Total cost around $300. $100 for the pressure treated 2x8s and 2x4s. $100 for the 1x4s and hinges (lid/bench). $100 for sand. Still gotta prime and paint the lid so It'll hold up the test of time. This project can be done at a cheaper price by making it smaller and using cheaper lumber. I estimated a 4ftx4ft would be under $200
