Re-Surfacing In ground Hot Tub

Hi All,

I am getting ready to resurface my in-ground hot tub (10 years old) and trying to decide on which material to use. I am considering regular plaster, quartz plaster and Pebble. Costs are ranging from $2500 to $6000 for a 7' by 7' foot hot tub. Any thoughts or suggestions would be appreciated. I am leaning towards Gemstone Sparkle Quartz due to cost ($3000) and smoother finish in a hot tub where your sitting around/in contact with the surface most of the time.

Thanks!
