I am building a sauna in my basement where currently the concrete floor has a drain but is not sloped (was set up for a tube). My plan was to roughen up the concrete, build angled screeding jigs (slope to drain 1.5%) and fill the floor space with concrete, mag trowel and call it good. Once dry, I will tile the floor and hopefully the water will move to the drain. I've heard from a few people that I should put a vapor barrier or bladder under the new concrete should water somehow get below the tile and conrete. This adds a whole nother dimension to an already somewhat complicated project and I question the necessity. This will get used 6 months out of the year maybe 2-4 times a week. Can i just seal the new concrete prior to grouting and call it good. Please help. I promised my wife we'd be sweating by Christmas.
