  1. Hmm, surprised at a few things he did….yanking a sink off laminate without first breaking the silicone seal around the rim is risky, He was lucky he didn't rip the laminate apart & had to buy the guy a new countertop. Didnt remove the disposal either…

  2. I prefer to put the silicone on the sink rim, then set the sink in place. I don't know what the professionals do, but that's always made less mess for me.

  3. I'm no genius, but if the disposal got disconnected before the old sink came out, it would of been easier.  Those disposals are heavy.

  4. I've a 50 year kitchen single sink tub.Similar to the one on this video with the metal strip around the tube.How would I measure for a new steel tub.? Do i measure from the metal strip ? And will the old wood break if I remove the old tub ?Measuring from the metal strip the height is 22" and the width is 25" will it be possible to find this size ?

  5. Do you not need to have clamps on a cast iron sink to pull it tight against the counter top like on the stainless steel sinks?

  6. I found SinkSEAL to be much easier to seal the sink perimeter than silicone. It can be found on Amazon and with SinkSEAL, there is no mess and you don't have to wait for anything to dry to use the sink. Check it out.

  7. Those traps are illegal..should've changed them out..i know it's a DIY show, but keep it up to code.
