What is the best way to remove ceramic tile prior to a full remodel?

I've seen this done before.. they literally smacked the tile with sledge hammer and then scraped the rest of the morter off with metal thing that looks like a hoe, but bigger. Very messy job and the dust will cover everything in your house. Good luck!

i would go to a home improvement rental place -like Home Depot and rent a demolition hameme. They make quick work of a tough job. This is a good video which shows what I am talking about. https://youtu.be/qDURxQlvuFs

Hammer and small handy bar. Break one or two to get to the edge and pop off with the handy bar. Wear gloves to protect your hands since ceramic tile does have sharp edges when broken.

Pry bar, mallet, sledgehammer, straight edge shovel, construction dumpster and a lot of elbow grease.

YouTube has any number of ideas: https://www.youtube.com/results?search_query=how+to+remove+ceramic+tile+floor

Once you get the old tile up, sweep/vacuum until subflooring is completely clean. Self-stick vinyl tiles are probably your cheapest, easiest option. I especially like the new simulated wood flooring. And the vinyl has come a long way, very durable and pleasing to the eye.

Use a spud! It's a heavy push tool that will lift up the old tile as you push it along the floor. Depending on the method used to adhere it in the first place it might be surprisingly simple... or not! If the tiles come out in one pice you can offer them to some place like Habitat for Humanity, recycle or you can just dump them. Home Depot and Amazon sell spuds or you might even be able to rent one. We removed 900 sq yds of asbestos floor tile using one! The entire lower level of our home was one big asbestos mess!
