The cost of a wooden rack depends on two factors: the type of wood and the design. Some wood like teak and oak are really expensive. But they have a distinctive pattern that gives you a unique finish. These woods are also extremely strong and can last for centuries to come. But there is cheaper wood as well. They might not look as good as the former ones and will require frequent maintenance to keep termites and other bugs from eating into the wood. And depending on how much carpentry went into the making of the rack, the cost will also go up.
