This old thread got revisited. @dani_m08 to answer the question about extra probe, I believe I ordered an extra one when I bought the set up. The probe wire is just setting in the junction box I think but honestly I cant remember. When I laid out the underfloor heating and the probe, I just ran another probe near the first probe, and it was then sealed into the floor self leveling compound as per instructions. then the end was just threaded into the wall like the one that would be live, and not connected, but just laying there in the box. Regarding the tile layout. I just decided to run it this way, after getting instructions on the 90Degree way, IIRC. The herringbone that I love is from my childhood and the side walks in my neighborhood that all ran at 45Degree. so that to me is herringbone. I know you posted on @sochi thread about her amazing bathroom and a wall mounted faucet. I would totally do it if I had the right sink for it. In my case I had made my sink out of soapstone and an integrated backsplash. The pictures of this bathroom reveal are no longer available because of the use of photo bucket, when it was Gardenweb. I did not keep my account with photo bucket. I'll add some of the reveal pictures so you can see the sink and floor. Regarding the sink there is no ledge for water to drip from my hands when using the faucet. The water drips right into the sink. In my other bathroom with a deck mounted faucet I am always wiping up drips and it is a nuisance. I much prefer the setup for this sink. Below: I love the flush finish from the faucet to the bottom of the sink. nothing drips on a counter or edge of a sink. Below: looking in from the doorway. Below: Here I am finishing up the sink. the backsplash was epoxied on as a separate piece. The whole soapstone install in the room took next to nothing to buy as they were all small pieces that I epoxied together with a 3 part stone epoxy. Below: this is the counter at the tub, and is in 2 long pieces but I was able to epoxy them together at there edges to make a wide slab for the top. All the soapstone was finished with a 60 grit sandpaper to be rough and this lovely soft tone of blue/green/gray/white. I did not oil it so this color tone would remain light. Below: If I recall correctly @sochi helped me decide on this Hubberton Forge Mirror. I have 3 different metals in this room, but they are all a cool silver to black color. Below: the center of this tower shares space with the kitchen on the other side of the wall. there is also some extra space that houses some electrical wiring. this is an old simple house. this bathroom was an add on when it got move to the farm in the 30s IIRC. The plumbing was all rearrange and some of the details that were orignially there I kept but updated it, such as this tower feature. The old one went and the carpenter did a wonderful job with this one. Below: This feature was another thing I kept from the old bathroom but flipped it from the other end and had the carpenter put drawers in it. Before it was a hell hole. things got lost and the build was soooo old and creapy I didn't like using it for storage. Now it is perfect for storage.

Is the door on the wall Suero drew it, or on a short wall? Are your walls regular 2x4 stud walls? is there any electrical, heating or plumbing running in the wall where the door is? Would it screw up kitchen cabinetry to move the door by half a foot or so? Moving a door is not a huge ordeal and might really help your bath layout, depending on where the door is now. A plan with dimensions would be great! Can you post one?

In the picture, black is the current layout. Green is the change if only shower was made bigger and one door would be eliminated. Red is a complet demo, removing the wall section between two toilets. All the water lines from upstairs are in the section of the wall that is between two toilets so removing this wall would require a major move of water lines to the side and there would have to be a section of wall kept behind new toilet and vanity. The door from master would have to be framed and move to the left as a pocket or barn door. The drowing is disproportionate. It is all very cramped in there Current shower is only 26"x26". But may be replacing vanity for a wall hung vanity in the larger bathroom would change the feel. It will all have to be torn down and replaced including removing subfloors as they are rotten. So either remodel will be a lot of work. What should we do?

The issue with putting sink and toilet on an opposite wall in this particular bathroom is that one of those walls is an exterior wall, which would be problematic for locating the sink there. It's possible to put plumbing in an exterior wall, but requires a lot of extra care and work and some plumbers may even refuse to do it because of the risk of freezing pipes. You could avoid that by swapping the tub to the opposite wall from its current location, but then it would necessitate relocating the door. There is also the question of the size and location of the window on that side, which may also require reworking. Having to completely relocate the plumbing and completely revamp the space would be a much more expensive/intensive project for the OP. It may be something to investigate but may not be a financial possibility. The current plan seems to be a much lower cost proposition as sink and toilet plumbing will not be moved and the reworking of the shower plumbing will be comparatively simple. It also does not require movement or reworking of doors and windows.
