Wet bath surface?

Getting ready to frame up my bath in my conversion and want some opinions. Its going to be a wet bath due to space with an RV toilet and a standard shower head. The black tank will be framed in and placed above the floor due to the tongue framing below. So the toilet is kinda of on a platform with the shower drain placed on the original floor. So here is the question. Any body had experience with LineX used in this application? Was gonna do my own fiberglass work and make it all seamless. Been reading up on LineX and it looks like a better option, especially from the labor and mess side of it. Their website says bonds to wood and has been used on boat hulls inside and out.
