I use the Rubbermaid plastic dishpans to hold all the normal "under sink supplies". I have two under both the mudroom and kitchen sinks, and one under the bathroom sink. All the cleaning supplies sit inside the dishpans. If I need to clean out from under any sink in a hurry, I just lift the pans out. When I first started using these pans I lived in base housing that had just gotten brand new cabinets. They were so beautiful and pristine inside; I was not going to mar them. When we moved, seven years later, the housing inspector would not believe me when I told him how long we'd been there. "But the cabinet floors are spotless!" Of course they were, nothing had ever touched them except the undersides of the new and always clean dish pans.

The smell was especially pungent for years because of the enclosed Cabinet. Previously we had a cabinet. Prior-reno. Now we have drawers. Now, with drawers, we have the storage that drawers provide. And things are airy. Every time a drawer is opened, air is forced to circulate. The action of drawer-moving pushes air around. I like to put a piece of paper towel covering the powder residue on the top of the Ajax/Comet, just to help keep it from going air-borne. (I think the powder can also go airborne even when you open a cabinet door.) This fine powdered product has some solid bleach in its granules, so we still do have a form of bleach under the sink. But the big old bleach bottle is history. It's amazing how much bleach bottles leak out pungent odors. Vinegar doesn't do that. It was a leap of faith to go all-drawer under the sink. Nobody ever confirmed that having not one single cabinet was a fine way to go. Many people opined that my proposed compact plumbing was impossible or not up to code. (Not true). Millions of people can confirm that the first bend in a drain can be and often is a "Tight" bend. (e.g. under a bathtub, under a WC, it's a tight bend), and Master plumbers can explain why a tight bend is OK as the first bend under a drain. As luck would have it, Franke, Elkay, Dornbracht, Blanco and others all sell a remote pop-up button that you turn to open / close the strainer in the drain. It's a cable that moves a lever. One thing they don't advertise is that your kitchen sink drain pipe ends up going sideways instead of straight down. THAT was the big advantage I had been looking for and found in this Ready Made Product that saved time since I did not need to Reinvent a Tight Bend in 1.5" diameter pipe. Result achieved: under the sink drain, my drawer floor is intact; it was not cut out to leave a notch for the drain pipe, because the drain pipe is horizontal and goes backwards to the wall. The P trap is in the empty space behind the drawer, close to the wall. I notched out the drawer's back panel, not the drawer floor. -- My drawer support structure is Really Airy. I have cabinet sides holding drawer glides. And Not One More Panel Than That. Drawers need no cabinet floor under them. We figured we could safely forego the cabinet floor as long as cabinet sides remained parallel and square (not parallelogram-y). This is another subject that could take time to describe, on another day. Our lowest drawer we can open with a foot since there is no wood panel under it. Having no cabinet floor gives you an airy open space. When you remove all the drawers (an easy operation) you can work in that space with room to spare. ((P.S. I also removed the cabinet back panel; i can see the wall and the plumbing very easily.)) -- Combining several thought processes we were able to get the final result that achieved our goals, satisfied our desires, (and made us proud). One was the radical rethinking of product inventory; we got out of the chemical storage business and got into the nano mechanical stocking business: we buy and try out scotch brite type and mIcrofiber cleaning cloths and pads now, and find them all good. Secondly, we got the drain pipe horizontally aligned and notched the drawer back not bottom. A third thought was that drawers need side panels for the glides but not the other parts of a typical six sided cube that they sell at the "cube" store.

My 1 HP is an Insinkerator also -- it just predates the Evolution series. It is very similar, but not as quiet. We had to replace the disposal almost immediately after buying this house. Since it was fairly new, we didn't see any need to replace it. If it should die, we will replace with an Evolution. From what I remember of reading the specs for the various Evolution models, they weren't that much different in size. DH wanted the 1 HP so he could peel potatoes and not worry about a clog (the only problem we'd had in the past). It was strictly bigger was better for him after we'd had a 1/2 HP we had to replace in the last house. To be honest though, he has peeled most of those potatoes at the prep sink since we put it in, and the 3/4 HP has handled them just as well. We haven't had a problem with either of them, so I usually just tell folks to make sure they hve at least 3/4 HP -- and the Evolution are quieter. Oh -- my 1 HP is under a deep sink in a 36" cabinet -- rear center drain. We have an instant hot heater tank, 2 sets of DW connections, a NeverMT with a warhouse bottle of soap. a basket for extra trash bags and a few less often used items, another basket for DW detergent and other cleaners, a trash bin and a recycling bin. Cleaning supplies should be no problem in a 30" cabinet.

I recently had a piece of sheet vinyl prove it's worth. It was in a rental, and she never told me that the disposal had rusted out. Water from the sink was draining directly into the sink base cabinet. After she moved, I discovered a pond under there. OMG gross, smelly. The floor of the cabinet was some cheap particle board. It had rotted out and sagged. Fortunately, the sheet vinyl I put under there had also sagged and formed a liner for the pond. None of the nasty water got out, and once we chipped out the destroyed cabinet floor, the actual floor was fine. I don't think that would work with tiles. Use sheet vinyl. And of course, don't let a pond form under your sink. :)
