We had our pool installed last spring and this year we are planning on installing a deck. We have an 18' round. We would like to install a side deck along with the splash deck all the way around. We were wondering if we build the deck over the top rail, how much space is needed between the top rail and deck to allow for future servicing of liner and whatever else is needed? Also what is the typical size of the splash deck? What else should be considered? We live in Connecticut and I thought I read somewhere about the lumber sometimes warps during the seasons so I'm assuming the deck would have to go over the top rail?
