As in a shared bathroom, you could consider installing a long bench and concealing your washing machine, dryer or laundry hampers and behind doors. Again, please be mindful that the machines are well ventilated.
Simply by adding a bunch of your favourite flowers and hanging artwork on the wall automatically gives it a homely and welcoming feel.
If you have a larger laundry, the addition of bench style seating with pull out drawers or baskets can be very useful to store shoes.
If located in coastal area, the addition of a shower near the laundry door would aid in reducing the chances of sand being traipsed through the home.
Entering through the laundry is a practical way to reduce dirt entering your home. By installing hooks to hang coats, hats, bags and other items that you routinely take with you when leave home, along with a streamlined shoe storage unit like the Howards Shoe Cabinet Drawers, the laundry can inexpensively double duty as a mudroom.
If you have a cat and are concerned about cat odour entering the rest of your home, consider putting a pet door on the internal laundry door. That way, your cat can still access the laundry if you close the door to reduce the litter tray odour and noise when you are using your washer or dryer.
If your pet is using your laundry be mindful to keep all chemicals up high or in secure cupboards to prevent accidental poisoning.
Create a dedicated space for your pet accessories, like a hook on the wall (like the Small 5 Hook Wall Mount) for the dogs lead and a small basket to store grooming supplies, treatments, toys and other accessories.
