Just had our Colorado Hot Tub installed by Terry and Harry. Couldn’t be happier. From initial inquiry to delivery date was less than a week, and the guys turned up on time, looked at the route the hot tub would take, and it was installed in around an hour. Everything explained fully and by that evening it was cleaned, refilled and the kids were in it! Im sure like everyone else we were worried about going for a 13 amp over a 32 amp, but we are surprised at the power this tub has. If you are considering it - DEFINITELY go for it! I would HIGHLY recommend the guys at BlackDiamondSpas. They make it all so easy. Cheers.
