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.

Looks like you have a couple thicknesses of plywood, then what are you putting over that? 1/2" cement board over the ply, then 1/4" tile over the cement board? If you haven't already figured it out, do you know how far forward the valve needs to be pulled? "As is", it looks like the supply tubing will fight the tub filler (if the vertical tube on the right is indeed for a tub). The hole in the stud on the left can be elongated, but with the way the pipes are configured you'll get a bit of twisting action on the valve when you pull it forward because of the tub filler. If it needs to be pulled forward a significant amount that might be too much for your configuration. Certainly figure out your depth requirements for your eventual wall thickness and make sure the extenders can work for your finished wall thickness. If they work, feel free to leave things as they are. Good luck!

Opinions on your questions: 1. Pocket vs. swing door: I'm not a big fan of pocket doors on bathrooms because they're more of a pain to close and lock. If you close and lock bathroom doors in your house. :-) 2. Benches are not mandatory. I prefer niches for storing shampoo and soap. Benches are usually to put your leg on when shaving. If you do have one in that corner, I'd recommend a triangular shaped one instead of square. There are pre-fab, ready-to-tile benches like this: I think the shower controls are fine where you drew them, on the bottom wall. Other thoughts: 4. code says toilet back to front should be 5' clear. Can you bump the wall a few inches to attain that? 5. I'd hinge the shower door on the other side. That will allow a towel rack on the bottom wall. You can easily fit a 48" vanity in that space. I'd definitely do it. On design, the typical "period appropriate" materials would be subway tiles in the shower and hex tiles on the floor. You could use natural marble on the floor if you wanted to splurge. I used larger hex porcelain in a powder room (not technically "period" but "in the style of"): With a neutral white/gray in the permanent stuff, you could pick your favorite splash of color for the walls. Or use that dark gray that's greenish, and use accessories, towels, etc. for the color. Your dining room is to die for, btw. Great work!

I am a designer coming up against this situation all the time...the client wants a beautiful, modern, functional vanity (storage + drawers) and the plumber comes in and destroys the vanity in order to fit in a classic P-trap with vent. No one is wrong exactly...it's just that the plumbing has not caught up with so many of our modern/sleek design solutions. Home owners and designers see vanities as storage solutions; plumbers see them as ways to hide plumbing. these are not often compatible. I am interested in teaming up with a smart forward thinking plumber to engineer some better solutions. Maybe the next time your client shows you their sleek and beautiful vanity you don't have to say "that won't work Mame"
