I found out that our kitchen water connection had somehow loosened up and was leaking water on the floor underneath the sink. Now the particle board cabinet floor is warped quite a bit. I was thinking about cutting it out and placing a Sintra® material as a new floor. Does anyone have any suggestions how to do this and if it's a good idea to replace the main floor plywood too. Or only replace the main floor wood if it's really fried? How or what tools would you recommend I use to cut out the old wood/particle board?
