An old bathtub would make an attractive and very functional veggie garden. It would be deep enough to grow several different vegetables including root crops and tomatoes. The drain hole is already there, and the tub would be large enough to grow a surprising amount of food. The tub would be classed as a container, so you want to use light potting soil or compost to fill it rather than regular soil, which would become compact and too heavy for the plants. Placing rocks or broken tiles on the bottom will make for better drainage for the soil and plants. As there is only a limited amount of nutrients in the soil, fertilizing every few weeks will help to keep the plants happy and healthy.
Use a pail of clean, dry sand as a storage place for small garden tools. Brush or wipe any dirt from your tools and then push them into the sand when you are not using them. The sand will help to keep the tools from becoming rusty.
An old bathroom sink, washtub, half barrel, large pail, a large pot, or large earthen bowl would make a smaller container garden for lettuces or herbs and would look attractive among your other garden beds, on porch steps, or on a balcony. With any container, make sure there is some kind of drainage hole in the bottom so the plant roots will not get waterlogged.
