Indoor pool flooring

[Kyle Smith]

I’m currently building a pool cabin in Gatlinburg and I’m interested in some opinions regarding indoor pool flooring options.  I will be pouring the pool floor next week and I had originally considered stamped concrete but now I’m sorta second guessing myself.  I got to thinking the stamped concrete may hold water and water may stay in the grout lines or cracks in the concrete causing potential mildew, mold etc. 
Has anyone considered epoxy flooring with a nonslip surface or what other options should I consider?  Thoughts?
Thanks in advance
