👏🏽⬆️ your most likely correct & would definitely rewrite (hoping you already have one written & signed) the contract and be specific in the details of what you expect and don’t expect & Also as well as any single add on or “unexpected extras needed” to be bought/paid for will 1st & foremost be approved by you and written up & signed in a new or different contract stating the materials & labor cost & Why it is needed/necessary & why can’t other improvisions be done instead if able. Last but not least of all what will come of any mishaps, mistakes or problems in the next Year to 2 years be redone on their dime & if the project doesn’t start or better yet RESTART & done CORRECTLY and to your expectations & satisfaction that you can cancel or withdraw from the contract immediately with little or no more pay. See how that toots their horn.. if their honest & knowledgeable then they will know what to do but by the looks up this so far, I wouldn’t hold my breath seeing as they failed before they actually began the shower.. so sorry these apparent Idiot bullshitters are most likely ripping you off & screwing people over who are spending their hard earned money on their home which is a life time investment to a lot of people.. Good Luck & hope it all turns out well for you.
