Hi, I am buying a 3ng resale flat. The 2 toilets are still in original state (MBR is sit and kitchen is squat). I want to renovate the 2 toilets, both has to be sitting. Hacking, tiling, piping, sink, etc. has to be fully done. Next, the kitchen is also in original state. Same reno as for the toilets, with addition to a simple top. Next, since the electrical wiring is also in original state, I want it to be done fully as well. Next, the flooring in the rest of the house is marble, so polishing should be enough. Next, chemical wash (necessary, right?) I have a budget of 15k for the above. Can it be done? Will I have anything left for other things, like hacking of the kitchen-living room wall? And/or nice ceiling design? Not sure I am clear enough or not. Plz advise, thx!
