Thanks Rick and Chris.
My home is a single wide with the kitchen in the end. The kitchen is about 11 X 12 and has a good sized eating area. No way I can afford to replace the cabinets, even though they are poorly constructed and designed.
The two major problems are inaccessiblilty and wasted space. Small, high cabinet over the sink required a step stool (which my son forbids me use when I'm alone) I use to store canning jars and supplies and a few rarely used seasonal items up there. Unfortunately all the upper cabinets are so high I can easily access only the bottom shelves where I keep our dishes and glassware and serving pieces. The base cabinets are even worse. there is only one shelf and storage space on the floor. In all three corners I have four square feet of blind storage on both the shelf and on the floor; my personal black hole of Calcutta. Since I can no longer kneel and still get back on my feet, I have to ask someone to help when I want something back in there. So that's where I store my dehydrated emergency food supply. My regular supply of canned goods is on a large steel shelving unit, which takes up a lot of space in this kitchen.
The bottom cabinet shelves are 13" above the floor. From the top of the shelf it's 21" to the bottom of the countertop. Wasted space!
Since cabinet replacement is financially impossible, can these storage spaces be improved without a big investment? We are considering removing the lower doors and cutting away the toe plate in the door opening so we can slide items out without having to lift them over a 5" board. If we cut back the door opening a few inches maybe we could attach some sliding shelves?
