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.

Would you essentially just be getting new fixtures if you kept it as is? They would almost have to grandfather it then: if not it would mean that you couldn't replace a broken toilet in an old house. According to International Building Code, a toilet and a sink can have overlapping clearances, so part of the knee space for a toilet can extend under the sink (9 inches, I think). And if you did 30" on center for the toilet you would have 15" on one side and 15" + 12" on the other, so the sink could be on that side. (However, you may be required to put the toilet 36" on center which would give you 18" on one side and 18" +6" on the other)

I think a large family room is a good idea. I like that you are doing a larger shower instead of a shower and tub. We recently moved from the snow belt where we lived over 30 years. The newer houses had 3 car garages, but in almost every garage, there were only two cars and sometimes one. People tend to store "stuff" in the garage. (We are guilty too). In our house we built 15 years ago, we did a 2 1/2 car garage with extra space in the rear. I would choose more room in the house and do a oversized two car garage, but make the garage extra wide and deep. Some of the 3 car garages have no storage on the sides or in the back. Therefore the 3rd stall is all storage. I think you would be wise to have a mudroom/ laundry room between the garage and house. It would also be nice to try and change the living room to where the kitchen/dining area is and move the kitchen/dining area to where the LR is now.

Frustratingly, you can easily pay that much to move too in our area of Northern CA; not sure where in the region OP is located, but guessing it may be similar. We costed both and ended up concluding we could do neither, so just added a second bathroom within the existing footprint and called it a day. Not ideal, but we discussed moving to areas farther out that were within our price range, and our kids felt strongly that they would prefer to continue sharing a room in our tiny house if it meant we could stay in our community. We will probably reassess when the older one gets to high school. The second bathroom definitely helps, though! OP, do you have kid/s now and are planning on adding more, or do you not yet have children at all? If the latter, I wouldn't hesitate to renovate now--you'll have plenty of time to enjoy it. But if you already have a child or two and are planning more in the near future, you will probably feel the limitations of the space sooner rather than later, so might want to make different decisions around investments. We have two kids and I think any more than that would be pushing it in a 2/1; most families we know with three or more kids ultimately moved.
