Just after Thanksgiving I moved my soap lab out of the dining room and into my bedroom. Sounds strange, but the fiancée and I were able to reorganize the bedroom to that I have a separate sleeping space from the soap lab.
So... in that room, I have one wall of shelves in the closet where I keep my base oils, small totes filled with fragrance/essential oils, and other miscellaneous ingredients (clays, salts, bubble scoop ingredients, unused NaOH, KOH, etc).
I have 5 bakers rack type trays on a side table for curing soap, and under that table I have the boxes filled with packaged product.
I use my 6 ft show table as my work bench.
On my "work bench" I have a two tiered shelf that I keep my mixing bowls, spatulas, and other tools/dishes/pitchers that I use every time I make soap. I also keep one container of NaOH, kaolin clay, sodium lactate, and tussah silk (which go in every recipe), a pile of clean rags, and a mason jar with pens and scissors (for in process note taking, cutting open my color mixing bags, etc.). This gives me about 4' of space to make soap in, which means I have to be super organized before and during the process!
Under the table is where I store extra PPE, stickblenders, clean rags, the trash can, the box with the dirty rags waiting to go to the wash, etc.
I destashed my book collection so that I could use one of my book shelves for my wooden molds, impulse sealer and heat gun, jugs of water, aloe vera juice, coconut milk, and my masterbatched oil buckets.
And last of all I picked up two storage sets from a neighbor when she moved - she said she got them at Ikea. They look kind of like this:

One is about the same number of drawers shown. I keep all of my silicone molds, fondant mats, packaging material (shrink wrap bags, labels, etc) and notebooks in that one. The other one is taller, about six drawers ... that's where I keep my odds and ends tools (extra spoons, skewers, cups and mixing dishes, thermometer), and my colors (one drawer for micas and one for oxides/natural colorants), and anything else I use for embellishments (candy sprinkles for cupcakes and such). I keep my cutter and my rebatch crockpot on top of these drawers. I also use dollar store baskets to keep things organized inside the drawers - for things like mica containers, etc.
