its fairly easy, but you need a power run that can support it, maybe even on its own breaker. Schluter and other companies have their own system and underlay you use, the schluter system you lay down their orange underlay with all these dimples and then weave the heating core through it and then put a skim coat over top

im sure theres plenty of videos etc online, the hardest part is probably the electrical part if you have an electrician friend etc
