Just in case you weren't aware, there is a "Husbands' Code" that most of us respect. It calls for never correcting a husband who has been creative with the reasons to get out of doing something. I'm afraid your husband is absolutely right. Okay, really, there's a lot of details missing here. Do you have a crawl space or basement under the kitchen? How many windows/Doors on that wall? My initial thoughts are getting the drain over to the stack under the floor. Plan B might be to frame out the wall 2x6 so that it's deep enough to put the horizontal run in the wall (and, you could fix the venting issue for the sink also without resorting to a quick vent). If there isn't an accessible crawl space, you might end up needing to tear up part of the floor. That's a lot of work, but you would probably be putting down a new finish floor anyway. If you build out the wall, that will be some work also, particularly if there are openings, such as windows, in the wall. I usually deal with homes that are older than this. You need to look at this not as an opportunity to fix the cabinets, but as an opportunity to fix a lot of the mechanical issues as well (such as not enough outlets) Both approaches offer the opportunity to pull new electrical and plumbing and bring things up to code.

todds, "Trap Arm" may be the notion you may need to work with. A longer "Trap Arm" lets peninsula sinks be properly connected to vertical vents that are in the closest wall. The window/counter setup you described is the same as whatever DWV plumbing setup happens for sinks in peninsulas of all shapes. No window needed. In other words, go pick up vertical venting over where there is no window. a.f.a.i.k. a house must have lots of real venting and almost no Studor/AAV venting. This is serious, in houses where there are toilets on a second floor above the main floor. It is less serious in a single-level house because there is no drain plumbing above the main floor ((i.e. on a second floor). Studor/AAV vents transfer air only one way, so they handle only "positive pressure". Real vents allow air to move both ways; this is required in most arms of the DWV plumbing branching tree. How to handle effluent is a serious concern, so don't let internet strangers advise you on cutting corners. Only someone on site can see the geometry you have in your DWV plumbing in your house. DWV plumbing requires a lot of 3D thinking. Words written are almost never good enough to describe everything, unless the person writing is a Master Plumber and the person reading it has the same level of knowledge allowing him/her to interpret the precise words, and they happen to agree on what they mean. This can happen in forums inhabited by Master Plumbers. But even there, it requires a few posts for them to go back and forth to be sure about what they mean. For many years, I have been participating in forums inhabited by Master Plumbers (under another handle/name). If you posted diagrams that showed critical distances very clearly, you could receive some comments that help you see more clearly what options you might have, in your case. When a DWV plumbing system is not well designed, it allows e.coli, salmonella, dangerous gases, and fecal matter waste contamination to spread beyond the area that should have contained it. In DWV plumbing an exchange of air for water happens every time you flush. The Studor\AAV thingie is an imperfect thingie that will one day fail (years from now); when it fails risk and danger are increased by several orders of magnitude. Before it fails, it is unable to handle air moving both into and out of it : it only lets air in, when negative pressure pulls air into it. Just remember that the answer to the question about Studor\AAV vents is always "maybe" until your entire house plumbing is known to the answering party. Hth

That's unfortunate. Are you familiar with Murphy' Law? Well, what can go wrong, will, and did in your case. There are some things that can easily be accomplished, however, gaining significant storage will require more extensive measures. You can move the recep. box mounted on the floor of the cabinet, to the wall, however, if there is an additional feed from that box, through the floor of the cabinet, it becomes more difficult. If you opt to eliminate the switch/s/ and install an air-switch for the disposal, than have 2, 20amp recep., 1 for the DW and the other for the disposal. Feeding the DW off of a recp. is fairly common, however, I'd relocate the place the cord comes into the cabinet to the lower rear corner. There are two option for the placement of the air-switch, switch. Either drilling the counter or installing it in the cabinet face frame. The disposal uses the high loop instead of an air gap, however, the hose can be shortened and connected. You may feel that the disposal is the problem, when it's actually the 2" waste line and where it penetrates the cabinet and the loop vent does not help. It should have been contained within the wall. Both methods of correcting that would require removing a portion of the cabinet floor.

Our remodel didn't require moving of the sink plumbing so we bought an 8 foot counterop from lowes (in their reduced priced section because it was damaged) for $20 bucks! We took our old stainless steel sink and traced a cut out of it in this countertop and took a jig saw and cut out the pattern. We nailed a 2x4 to the wall where we wanted the back of the counter and set it there and took drywall screws and attached it. Then we took more 2x4s and used them as legs to support the counter then dropped the sink in and hooked up the old faucet. We didn't have a KD or a GC so we were lining up our own contractors and there was down-time between jobs so this counter came in very handy. We also built a makeshift island out of 4x8 plywood (cut to our future countertop size of 3x6) and used 2x4 legs to support it and used 2x4s for support and stability underneath of it. We placed in in various locations (adjusting it by inches)to get use to it and it's placement before cabinet install, just in case we wanted to allow more space between aisles. Here is a photo of both...
