If you are having a spa or hot tub delivered to your house, be aware that the shipping company does not usually install or wire your tub. Usually, they will require a space accessible to a large truck where they can unload the tub. If you can clear space in a garage and if there's room to back in the truck, this will probably be safest. Some shipping companies will charge a hefty extra fee for transporting the tub to the back yard.
If you order your tub or spa from a non-local dealership, it may be safest to choose a company that does its own deliveries. Employees of the spa company are more likely to be invested in delivering its products safely, and knowledgeable about handling them. Your local dealership should be able to make arrangements to have your tub installed and wired soon after delivery. Be sure to ask questions about time frames and fees before committing to buy.
