Softubs are lightweight (about 80 lbs) and can be rolled into place. They aren't cheap, they cost as much as a regular spa, but we loved ours. They last a very long time. They use 110 v. and are cheaper to operate electric. I cannot imagine trying to move a regular heavy spa from the curb. Some of the blow up spas you buy on Amazon may seem fine in the pictures but our son bought one and the motor was so loud he couldn't operate the jets while he was in it. There may be others but he had an Intex I believe.
