Agree with the above and would like to add that in my experience, the dust from toilet paper tearing and the skin cells that we slough off in the bathroom just build up on surfaces around the toilet and sink for those of us who do not wipe these surfaces down every week. I have some things near my toilet that just get covered with dust. Then anything on the toilet itself is sitting on colder porcelain. It is colder because of the cold water it is holding. In the humid air of the bathroom that means that water then condenses on the outer surface of the cold porcelain, mixes with the microscopic skin cells and paper fluff and powder and it just STICKS to the surface. It builds up around the tabs of the toilet seat screws because that is where the dust stops when it is blowing around the room. Any sharp angles on a toilet will do the same thing. The solution is to wipe surfaces more frequently. I had to start buying the disinfectant wipes when I had an incontinent dog. So, now that I have them in the house, I will use them in the bathroom. I wipe the toilet flush handle, the top of the seat lid, the underside of the seat lid, the seat and the underside, then I go behind the seat and get the area you photographed. Next, I get the rim. I might use another wipe and do the door handles, the switches, the faucet and handles on the tap, then the tank lid, then the outside of the toilet bowl and use the last wipe to redo the rim if it was still not perfect. I always move from the cleanest places to the grimiest places. A third wipe would do the windowsill and the counter. Now, I may not do all three wipes at one time, or in one day. I may see an area that is yucky and do one wipe's worth that day, then another a few days later. I also have disposable rubber gloves around and if I am in the mood to clean I will put on one or a pair and scrub the toilet and do all the wiping and vacuum and mop the floor. My goal is to not be embarrassed to let someone use my bathroom if they should drop by. I am a messy housekeeper, but I can still be a CLEAN messy housekeeper, I figure!

I agree with Cpartist"s layout and like moving the closet over as suggested by D M so that bedroom 3 has easier access to the bathroom. Do you have room to have the toilet face the tub and add a linen cabinet next to the toilet? How wide is the tub toilet area?

FinPan Underlayments They are saying the cement board is waterproof. Is that correct? NO! Absolutely NOT!! See the info linked above. The ProTec product used in your showers is water 'resistant'. It is NOT 'waterproof'. Note that you have the cement board product. Which is ordinary run of the mill cement board that requires additional waterproofing measures. Either poly sheeting behind OR surface waterproofing like RedGuard, etc. You do not have the FinPan Pro Panel. Per the website: ProPanel® is a new generation of backerboard that offers waterproof performance all in a six pound board that is mold and mildew resistant. ProPanel® consists of high-density expanded polystyrene reinforced on both sides with fiberglass mesh and a polymer cement coating. It passes ANSI A 118.10 test for water proofness. It does look like the Fin Par ProTec is labeled as waterproof on their website. No, no, no. ProTec is labeled as water resistant. ProPanel is the 'waterproof' product. Again, you have the ProTec 'water resistant' cement board.

I just had my shower/bath area in the primary bathroom retiled. The tilesetter put up the tile probably Wednesday. He grouted it the next day. It has not been sealed yet. It's quite obvious that the thinset has not dried behind the tile - especially obvious where the accent mosaic has been placed. Some of it had dried by the next day but you can see where it has not dried - the white marble looks gray. It is now Monday the following week and this is how it looks. Since it has already been grouted, I am wondering if this will ever dry. The floor area looks a little odd also and I am wondering what's up with that. There are also two tiles on the edge of the window by the bath where he sanded the edges. I don't understand why that was done - it seems to me that it would open up the marble to moisture. The tilesetter also put up cracked marble mosaic tile in my kitchen backsplash. Since the marble has little veins, it is very hard to tell it's cracked. It's been filled with grout and sealed. Am I going to have any staining problems from it being cracked? Should I have him replace those tiles? Any input would be appreciated.
