I want to redo our basement bathroom from ugly yellow to something more modern. The tile floor is very small yellow tiles and I was wondering if it would be easier to just tile over it or wrip it up and put a new floor down. Thanks!!!

You need to have a solid surface for your toilet to sit on otherwise it can rock loose and leak. Though more time, work, and money, I would suggest you remove the old and start from scratch.

Your best bet is to remove the old stuff first and start over otherwise the new floor would degrade rapidly and you’d have to rip both out.

Remove the tile and start from scratch. Tile need a smooth and solid base to adhere. Thinset or tile mastic will not hold. Also the height would be increased.
