    Spa size (Is it possible to make the spa too big?)

    What would the ideal size round spa be? If you had to do it again what size spa would you install? We currently have an 8' round spa in our new construction pool contract but it can be changed if required at this time. Seniors with kids and grand children.

    A 8ft spa will hold 8-10 people and 7 ft spa will hold 6-8 people, I'd stay with the 8ft spa

    Is this anything like a pizza, where they say it serves 10 for a giant, but it really only serves 4? :P

    An 8 foot spa should be good and would be my choice if I had the room for it. Do remember that the larger the spa means more time that you will need to heat the water. We use our 7' spa all year long and are usually in it 3-4 times a week during the winter and need to raise the temp from around 60 degrees.

    They have quoted a 333k btu propane heater. Do you think this is big enough for an 8' spa?

    When it comes to heaters, the bigger the faster they will heat the water so I would go with a 400k heater. I have that on a 7' spa and when it is really cold out, it can take over an hour to heat the water from 45 up to 102. It will take a 8' spa 30% longer to heat up.
