jk, that is the others method that I use too. So far, it is working fine. It can apply for indoor or outdoor as welll.
David, my method is for outdoors... If you want it for indoor, you may need to link the hole to 'water tube'. and have a controller to control the water flow. So that, water will not dirt yours room. Besides that, you may need the "water tube" to each others. So, at the end, all water from water tray flow out to yours toilet using just 1 tube.
ps: Link all tray together is what I initial plan...
Lazy to find meterial causing me to use chock. Say is more easy then do it...
