Ron Van, I use the pro version. I just splurged and got some of Fredo's plugins but I need to install them. I'm still terrible at lining up the pipes in sketchup though.
I just got completely distracted by one of my cats running around the room like a nutjob. He's now hollering at me.
Anyway, upon further research I discovered that the suds relief rule is obsolete with the newer front-load machines. My revised sketch:

And I can use these for where the pipes go through exterior walls: Low Profile Master Flash®

How far is the toilet from the main vent stack?
~5' and it has to be within 6'. But I can run it to the wall a little bit closer and then branch over (as I don't want to conflict with water supply lines and other stuff).
I'm starting to think rather than adding 45s to the vent or drain on the lav I can jut push it all the way through the wall and have a membrane designed specifically for pipes going through exterior walls. Low Profile Master Flash® and then have it go under the house. I can wrap the exposed drain part in insulation.

One concern I have about connecting to that vent is that I think it is only 2" (if it is that large) and if I am reading the rules properly, it can only handle 6dfu and I'd be putting 8 dfu on it. However, the shower will never be run while the laundry is running so the max that would be running at one time is 5. (toilet and washing machine are 3dfu each and tub is 2dfu). It's unlikely the toilet would be flushed while the shower is running. I could be mistaken on the max dfu for a 2" vent though.

I'm going to need new walls around my tub/shower. Found a potential one but its' out of stock. 59" and I have a 60" space but I can make it 59" or thereabouts with some cementboard. Might still look and see what they have in stock locally at the hardware store. I'm looking at glue-up stuff. Wish I could find direct-to-stud for a decent price that would fit with my current tub. I believe this tub has no flange though. For the cementboard I'm looking at: https://www.lowes.com/pd/James-Hardie-0-42-in-x-36-in-x-60-in-Fiber-Cement-Backer-Board/1001066302
It's $24/sheet and only 3'x5' so I will need more boards. Also considering the purple drywall https://www.lowes.com/pd/Gold-Bond-...-ft-x-8-ft-PURPLE-XP-Drywall-Panel/1002062128 which is 4'x8'. I will be painting/sealing it up.
I was thinking of going with this tape: https://www.lowes.com/pd/Saint-Goba...onstruction-Self-Adhesive-Joint-Tape/50183375 or this Fibafuse stuff https://www.lowes.com/pd/Saint-Goba...x-250-ft-Mesh-Construction-Joint-Tape/4411371
I think it would work with either option of board. Also thinking of getting Drylok paint but considering using flex seal in the corners and over the screws. The tape doesn't require mud to adhere-- it is self-adhering, but I'm pretty sure I need to put something over the tape.

So, any suggestions on this?

Hello @zannej
I am a little high on drugs at the moment, wasn't a good day for pain... I have some stuff in the garage for waterproofing the tub or shower walls... Two coats and NO moisture will make it to the inner wall... I am so sure of this stuff, I didn't go with cement board... Went strictly with drywall... Did my last house like that... and had a tub, and shower separate... and never had a moisture or mould problem... It was very expensive... But I am sure in the States it's affordable... I will get the name of it for you tomorrow, and in case I forget this conversation, Just give me a little kick...

It seems that 60" surrounds are more common like this one from Lowes;


It can be installed over cement board, drywall or even old tile (if it's flat).

I think it would work with either option of board. Also thinking of getting Drylok paint but considering using flex seal in the corners and over the screws. The tape doesn't require mud to adhere-- it is self-adhering, but I'm pretty sure I need to put something over the tape.

Yes. Here's a good video on a shower install.



The waterproof membrane RedNeckGrump was thinking of is RedGuard, or from Lowes it's called AquaDefense. You paint it on with a roller or brush (usually two coats) and it's bulletproof. I used Red Guard on a bath remodel in our old house and again on a kitchen remodel in our current house.

This shower turned out beautiful but it was very expensive.

IMG_5016.jpg

Here you can see the pex plumbing of the Hansgrohe iBox rough in for the shower valve.


IMG_0520a.jpg

I used cement board and red guard on the entire floor before tiling it. I know now that I should have sealed the screw holes. Oh well, maybe next time.


IMG_1040e.jpg

This was a custom corian shower surround that was marvelous but cost $8K. The glass was another couple K. My challenge now is to build two new baths in our current home, that looks nice, for way less! I'm looking at off the shelf solid panels that glue to cement board. I will use the waterproof membrane over the cement board.

I finished this just before covid hit. At that time, my wife said, "We're moving out of this state!" and here we are in Alabama starting a new project!

IMG_0206.jpg
Original Bath. The shower was leaking out of the hinge side of the crappy little door and rotted a hole in the floor that I had to fix during the re-model. You can see the discolored linoleum. I vowed to waterproof the heck out of everything.


IMG_4938.jpg

I ended up cutting the wall back and replacing the floor sheathing here where the shower door leaked. This is what happens when showers are not waterproofed properly.

This is where the floor rot was. The wall was cut back and then extended later. The flooring around the toilet had to be replaced as well.

I cut out the rotted area around the toilet flange

Cut the flange off.

I had to build a frame for the new floor sheathing to rest on.

IMG_0720b.jpg

Tiled around it

I used a Culwell Floor protecting toilet flange. I may have gone overboard but I was determined to waterproof this bathroom!

There is no way for water to get to the floor even if the wax ring fails. I used red Guard all around the flange before I tiled.
IMG_0720d.jpg

This is a two piece toilet. The top part of the toilet sits on top of the plastic bottom gizmo. It's pretty nice to be able to see the toilet piece on the wax ring before setting the toilet on it.

I liked the two piece toilet for the ease of installation but my wife liked the smooth sides on the base for ease of cleaning.

I've installed three of these toilets so far and no complaints.

This picture didn't post properly above. It's the Red Guard treatment over the sheetrock. The solid surface shower surround doesn't require cement board.

IMG_0612c - Copy.jpg


Because of the surround that was used on this project, there is no way for water to escape the surround system. On my next shower install, that may not be the case so I will waterproof a little better before installing the surround.

IMG_0620a - Copy - Copy.jpg


They used foam under the corian shower pan (which was very ridgid). A 2" compression type drain was used.

IMG_0620f - Copy.jpg

The corian was glued to the wall but notice the sheet is not full height yet.


IMG_0620m.jpg


The top section was glued on to the the bottom section like a coutertop would be done.

IMG_0620n - Copy.jpg


IMG_0620o.jpg

Then, corner pieces were glued (bonded) in.



IMG_0620u - Copy - Copy.jpg

Then they used a special router to make a radius in the corners making it appear like a solid one piece surround.

IMG_0620v - Copy - Copy.jpg

The seams were invisible. They glued the grab handle and shelves in place. Whatever they used to glue it, it was solid. You could hang on those shelves. The bottom shelf was for my wife to put her foot on to shave her legs. Notice the concealed drain.

The dogs are inspecting the work. You may recognize them from my kitchen remodel post in our new home.

IMG_0220.jpg


We were using the old shower right up to the last minute during this remodel. This photo shows a vent line in the pony wall (that was removed). That vent line replacement became the biggest challenge of the entire remodel. Like I mentioned before, Vent lines take up the majority of the plumbing code because they are complex!

Redneck, any sort of building supplies are expensive in my area. I wonder if just the Drylok will work or flex seal. Looked it up and red guard isn't carried locally. Aqua Defense or something from Mapei is though. It's expensive. I'd have to compare prices with something like Drylok. I still plan to use the purple board since I'm familiar with it & we've used it before at my friend's house.

I want to get a decent surround but want to stay under $400 if possible. I like plain white.

Ron, thank you for the pictures and input. That closet flange is very cool. I wonder if it fits inside a 4" hub or just inside regular 4" pipe. Found one on ebay "new" for $15. Might jump on it and order it. I wonder if they have more than one and if I should get one for each bathroom. I also wonder what installation procedure is for surface mount on a floor with vinyl sheet.

I found specs for my toilet and decided that a pressure treated 2x12 can work as a platform to lift it a little higher. It will make it the same height as my friend's toilet. I can set the other toilet on it, trace the shape, mark the bolt-holes to line up the flange, cut a hole for the drain, use 4" screws to anchor the flange to the platform & the toilet (after painting the board). So, it's more of a board than a platform.

Cat presented my face with his butt and made me lose my train of thought. Then another one bounced in here and accidentally cut my lip with a claw on his back foot.

I forgot to comment on the video of Jeff. I have been watching a lot of his videos. He's entertaining. bonus points for him quoting Red Green.

I found your review on Amazon, Ron. I thought the pictures looked familiar. Mom's bathroom has the same thing going on with a joist/beam being close to the flange. It's what stopped the toilet from entirely falling through the floor when the subfloor gave in. Looks like the A43 is sold out or only sold in massive packs instead of single. I'm hoping the 4" one could still work. https://www.ebay.com/p/698152018
