The key to organising success in our laundry has been factoring in WIP. That is the 'Work In Progress' element.
I actually share a laundry space with my mother-in-law and her husband who live with us in a self-contained space which was formerly our large double garage. Their space neighbours the laundry and it is our one common area in the house. With a family of 5, I wash most days while Mother-in-law does washing only two mornings a week. I try to make sure the facilities are free for her set days, but it doesn't always work out that way, depending on whether the kids have generated a mountain of dirty washing from playing outside or going swimming. I always have laundry on the go - at some stage in the process. That is why I set up a laundry holding system with laundry baskets and shelving to hold laundry WIP (laundry in various stages in the process).
This system relies on me emptying the machines once they have finished their cycles, but it also means that if I don't get around to emptying the machines and Mother-in-law wants to use them, that there are still basket(s) free for her to empty out the machine and use it right away.
Once upon a time I used to have 2 laundry baskets that were always full of washing to fold sitting in my lounge or bedroom and a tonne of washing backed up to be washed. There was no where to hold clean washing ready for the dryer if the dryer was in use, so it would sit in the washing machine until the dryer was free. It was not the most efficient use of space or time.
Now I have a shelving system next to the machines that can hold 3 full laundry baskets. This means that a can leave my laundry on the shelves until I am ready to deal with it - one basket at a time. I can get another load of washing in the machine if the dryer isn't quite finished and I don't have to bring dry washing into the house and dump it out to free up a laundry basket. The washing is contained and I don't feel overwhelmed by piles of washing to be folded when I'm busy with the kids or other chores.
I recently introduced a further two (white) baskets. These are available for extra heavy wash days. They are easily stacked away under any of the other baskets when not in use, while giving me extra leeway when chaos descends on the laundry.
I have intentionally used the 3 middle shelves of the 5 tiers for practicality. It is not easy or practical to lift baskets of laundry up to the very top shelf or from the bottom shelf, but I have still made the most of these spaces. The lower shelf stores laundry powder and a small rubbish basket for dryer lint etc. the very top shelf stores dog grooming equipment and bedding - as I really only use this once every couple of weeks.
This is my laundry system and it is working so well, I just thought I'd share my success.
