Welcome to our forum.
Here are your options:Reconfigure your existing panel to allow the addition of the new 60 amp 2 pole breaker for your tub. this will require the addition of piggyback breakers for some of your 20 amp loads. This is the cheapest option. I would still recommend that the electrician complete this work. It can be done by the homeowner, but you need to know what you are doing.Secondly, add a sub-panel next to the existing one. This could be a 60 or 100 amp panel. This would allow for additional spaces that you need. Lastly, replace the existing 30 circuit panel with a 42 circuit panel. This is the most invasive option and could require involvement of the utility company.I would go for option 1 or 2. In any case, if you feel like you are getting the shaft, get a second opinion!!!30 Yr Electrician
