Have aquatainers. GREAT things but..... they sit on the counter and yes you CAN wash your hands, brush teeth etc. but YOU try washing a pot! NO clearance at all really. Came to conclusion that we need to elevate them to get more clearance but also need a small 'hose' so the water can be directed to the sink/pot/etc. Length to be determined later.
You could try the spray bottle methode; fill spray bottle with water and dishsoap; spray on whatever needs to clean, clean with brush/sponge, rinse with another spray bottle with just water (a little more powerful sprayer can be handy).
