You might be wondering what the point of this is thus far. Basically the bathroom and laundry room do not work as-is. Because of the plumbing and a shelf behind the washer and dryer, there is barely any room to deal with laundry. I constantly find myself bumping in to the southern wall and there really isn't space to fold the laundry. After getting measurements and kicking around ideas with some folks on Houzz, I finally realized that the best solution would probably be to swap the bathroom and laundry room. This would make it so that the bathroom could have more space and the laundry room would be easier to access. No more trying to squeeze through that narrow hallway with a laundry basket in tow! On paper it may look spacious, but we have some old wall panels stacked up against one of the walls and they are taking up space. The bathroom is currently serving as a storage closet for junk because there was always a foul smell in there (likely bc of the improper venting).
The washing machine currently does not appear to have P-trap nor does it seem to have a vent.
Since there is already a door arch leading in to the laundry room, we could add a frame and install a door.
Here is a sketch based on the isometric drawing of what I would like to do with the space.
Red * represents current position of light fixtures. The bathroom has an old failing light/heat/ventfan. The laundry room currently has a small ceiling fan with the fan kit installed upsidedown.
The washer/dryer could be moved over either north or south or separated with something. I would love to find a way to have a murphy table that I can use for folding laundry but then fold it back when its not in use.
Here is the rough plumbing diagram I sketched of the possible changes. (This does not include tie-ins for the kitchen sink, nor the other bathrooms)
A brief note on plumbing code in my state:
Other relevant plumbing code updates for my state:
In case images are not working very well, here is a summary of what I plan to do and why.
* Find out what permits (if any) are needed and obtain them. The health inspector told me that they were not needed in my area, but I need to be certain.
* Tear down east and most of north wall of bathroom.
* Install 30" doorway with door swinging outward (northeast) to avoid collision with walls or people using lavatory. Inward swing would violate minimum code distance of doorswing from front of lavatory. (I think about 24")
* Leave wall switch for light in place, but install GFCI outlet on west wall next to vanity (as per code requirement to have GFCI outlet available within reach of lavatory).
* Move toilet to north wall of new bathroom at least 18" from center of toilet to side of tub (minimum code requirement 15"). This way it would not be too far from the main vent stack. I considered putting it between shower and lavatory but it would be too cramped as the vanity is 26"Wx17"D.
* Install euro style vanity (already purchased) in southwest corner of new bathroom-- where the old utility sink was plumbed in. I would either have to move the plumbing inside of the wall or have a small bulkhead to bump it out to avoid having to cut a hole in the drawer. Or I could bump it forward and have a shelf behind and build out a box to hold the medicine cabinet that fits between studs- that way I could avoid having stuff go in to the exterior wall.
* Remove all wall panels and install insulation and moisture barrier.
* Rip up floor in new bathroom down to the joists because the floor is badly damaged. Add a moisture barrier in the floor.
* Install a 30"x60" tub against east wall of new bathroom.
* Install handheld showerhead 7' high on north wall of tub.
* Use wonderboard Lite 1/4" for walls of shower/tub and install a 5 piece shower tub surround. Cut the surround to fit around the window, add some sort of curtain to keep water off of window when showering, add 1/4" slope to window sill to drain water and seal things up to prevent water damage in case it gets wet.
* Make sure floor is reinforced to hold weight of tub.
* Seal up existing hole for dryer vent and move it north on the east wall. I have some spare siding to cover it on the outside.
* Move washer/dryer to the east wall in the area that used to be the bathroom. Put sliders underneath the laundry pedestals to make it easier to move them without scraping the floor.
* Use existing water supply from old lavatory for washing machine and install one of those laundry outlet box thingies (need to find the right one)
* Move power outlet for washer/dryer to a spot that both appliances can reach easily (preferably somewhere that is accessible should they need to be unplugged)
* Replace floor in hallway and new laundry room with vinyl plank.
* Install vinyl sheet flooring in new bathroom.
* Move ceiling fan to new laundry room and fix the fan kit.
* Install NuTone 70CFM vent/heat/light in new bathroom ceiling.
* Cover missing ceiling tiles over tub area with something or just replace fallen tiles.
* Make sure that all water supply lines are to code (CPVC or approved metal).
* Figure out what fittings to use for DWV system and the correct order in which to hook things in. (I'm still a bit confused about some of the rules on upstream and downstream).
* Have cleanouts in appropriate places.
* Pressure test the pipes.
* Enjoy the new setup when it is complete.
I have an electrician friend who can do the wiring for me and who can help with the plumbing if need be (he is skinny and can fit under the house-- he recently redid some plumbing at his own house). I need to find out how much of the work I can legally do myself. Since most of the work appears to not have been done to code anyway, I think whatever I do would be an improvement because it looks like the current setup was done by a monkey.
So, I guess my questions are:
1. Does anyone know if I can legally do my own plumbing so long as it is to code?
2. How do I pressure test the pipes?
3. How do I prepare the space to install a tub in a place that has never had a tub before?
4. Any ideas on good 30"x60" tub surrounds? I'm looking for a kit that has corner shelves. The more shelves the better. I suppose it can probably be wider than 30" if I add trim or something. I'm not sure what trim to get for that though.
5. I've heard of something called a "plumbing box" for routing pipes through walls, anyone know more info on those?
6. Does my plumbing diagram look ok? Should I make any changes?
7. What fittings should I use and in what orientation should they be to hook in to the main soil pipe? I'm thinking some wyes with 1/8 bends sweeping downward toward the west.
8. Where would I need the cleanouts?
9. From what you can see of the images, does it look like the main vent stack pipe is of sufficient size for the load?
10. Is this diagram actually the real code rules? Does the 24" space have to be on both ends of the tub (because most bathrooms I've seen have the toilets closer than that) or is this just a general guide?
That is all I can think of for now. I appreciate any feedback.
