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.

Lysol is the best, and you can always spray the door knobs, toilet handle, fixtures, etc. B&BW sells inexpensive sprays that do look cute sitting on a counter. I forget what mine are but they come in a silver can, around $5.00 each. They're small and last a long time and doesn't scream "air freshener!" lol

Building exhaust systems aren't typically filtered in the way you're thinking so I'm thinking it would be difficult to find and fit something that would work well. If your concern is weed smoke, that smell is so strong and so pungent (especially if coming from a small room) that I think it unlikely any jury rigged approach you come up with is likely to be effective. My guess is that the scent will be detectable no matter what you do. Nowhere more than in your living space. I've been into many places that reek from weed days later, haven't you? Do you plan to keep doors and windows closed forever? It seems to get absorbed into walls and other hard surfaces and (remembering apartment days) can often be smelled in other apartments. The great outdoors is your friend, take a hike.

Thank you, Labra DB. That's probably more expensive than I am willing to do, and, since the door will be open pretty much all time, so no need for frosting. What are your feelings about pocket doors for this space? I thought that since the door will be mostly open (I do have a pocket door on the 2nd floor bathroom, and it works out perfectly) the pocket door will allow more wall space for art.
