I'm sorry guys, this one is too good to pass up. Hate to be the pro in the room, but, my contractor hat is spinning. I have to ask kacalapy few questions before I can even breath again. My first question is, have you ever gutted and rebuilt a bathroom? Do you have competent electrical, plumbing, drywall, carpentry, tiling, flooring experience skills? Do you have a truck full of specialized tools and the experience and knowledge to use them? Not to be absolutely negative, it is really important to know your level of expertize.
One thing I have learned over the years is to expect the unexpected. nothing in a renovation ever, and I mean ever go smoothly. Tolerances are never right, things don't fit. electrical feeds are old or not where you need them, drains don't line up, rot is found, framing for new tubs and surrounds always has to be done, mortar bases installed, vapor barriers installed, closet flanges replaced, damn, a rotted floor section to be fixed, old valves replaced, mixing valves won't solder with a propane torch, Opps, I got a leak!!! Darn I have to build a ceiling joist box and a soffit vent. How do I rock to the nail flange? Seal the floor? Fortified grout? You mean I have to drill my own holes in this brand new surround? Hammer arresters? What's plumber putty, where? need I say more?????
I always figure a full week, a master plumber and a lot of aggravation, but that is what I do for a living. I absolutely love the DIY books and shows. A bath is done in a one hour show with no problems, and the books show the basic steps, but they don't show the tricks of the trade. Taking on a complete bath rebuild in a very big job. If you don't do it right the first time, it will cost you so much to fix it up after. Get a pro to help you if you don't have the expertise. There are so many pitfalls that will stop you dead in your tracks. You need to know exactly what you got to start with and plan to adapt the new to the old.
I wish you good luck, but never trust a book or TV show. Trust a pro!! Watch a couple of episodes of Holmes on Homes to see what a bad job can mean. He is my mentor and hero!
