The fuse blowing is more than likley something wrong with the tub, such as a bad heater, not your home power. If you want a working hot tub I would have a service company come look to see what repairs may cost. I highly dought you will be able to sell the tub for anything, 4 jet built in lifestyle tub is pretty old. I would have it repaired or sawsall it and remove to redo your room.
