Bathroom renos can be daunting as there are many things to consider and usually the space can be limiting. Free standing baths are stunning and come in many shapes and sizes. You have mentioned that you and the boys will use the bath, ensure you factor in the "users" height as this will determine the bath size and depth. Firstly is the plumbing remaining in the same position? Floor mounted bath mixers can be installed with a concealed under floor box or the above floor connection method. The concealed box method is advisable before the flooring is installed, and has the benefit of a lower profile floor plate, which is preferred. The above floor method may be done where the first approach is not possible. Free standing bath mixers visually create an impact when paired with the freestanding tub, ensure you have enough room around the tub as it will be difficult to clean if it sits too close to walls and or vanities etc..many freestanding bath mixers offer functional hand showers as well as the spout, ideal for washing soap out of kids hair. Would love to see a lay out of your bathroom to assist with tap ware placement. Good luck with your bathroom renovations, always happy to assist you. Carmen Collaborative Interiors

Have you priced having the whole lot re waterproofed and tiled? You are already doing the hardest section, it may not be that much more to do the lot. Otherwise agree with above match to the white tiles in the rest of the bathroom. But it will always look like a repair.

Moving the niche is not an option at this point. But I do have a question about the niche. My tile installer wants me to consider using the gray tile (same as the floor) on the inside edges of the niche. This is because the wall tile is glass and imperfections in the glass (from cutting it) will show if the glass tile is on the inside edge. How do you guys think that would look? I tried to find photos of a niche where the wall and back of the niche were one color, with the sides being a second color and I couldn't find any examples. Has anyone seen that?

No, builder coming around tomorrow for first time, as is Class 2 designer (been a rush to get a bunch of class 2 consultants on board for a simple reno). So far all my own investigations. The slab is structural, 275 thick with localised thickened beams over the posts in the carpark. Opening it up would probably be refused by Strata. I can go look at the original structural details to see how much cover is over the reo - maybe I can get a 20-30mm scabble and do the rest with screed to cover before tiles. It'd be very flat though. Will need a structural engineer to sign off on the detail, and if I'm honest, I'm uncomfortable reducing cover to the reinforcement as below and think it opens up a bunch of risks. I'll run this past them tomorrow for their comment though.
