After hours of tiling and late night softball, my old muscles get pretty darn sore. After about a month of research of the top rated hot tub / spas on the market I decide to go with a Caldera Utopia Series spa. The Utopia series offers lower maintenance, a modern look, and very high end overall look. After deciding on the spa, how to reinforce the deck as the deck I built was not originally designed to support and additional 5,500 pounds.
I dug out four additional footers, then added a layer of crushed gravel. I then placed a 6X6 weather treated post in each footer followed by what seemed to be an endless amount of concrete. I then ran dual 2x10 beams between each post. Finally for added measure, I cross braced the post for additional support in case of unexpected lateral forces. (a.k.a. water sloshing & wind)
It took nine men to lift the spa on the deck. I suggest you have a team on standby the day your spa gets delivered.
After about a week of use, we quickly realized we needed a place for our towels near the spa. I DIY'd a simple towel holder utilizing an old rusty umbrella stand and a curtain rod. I repainted the curtain rod and base, then placed three hooks on the end of the rod to secure our towels close on cold winter nights.
