This is my first Instructable, thus I might left some details out, if so, please let me know and I will clear any doubts you might have.
I recently remodeled a shower for a family who needed a walk-in shower with a ramp for easy access for a member of their family whom suffers from quadriplegia.
Once there, I noticed some broken tiles that needed to be replaced as well.
This type of work involves the use of blades and sharp tools. There is going to be flying debris, slivers and shards, always use the adequate protective gear.
Wet tile saw
Sledgehammer and chisels
Grinder with a diamond blade
Blue masking tape
Special waterproof pencil to mark the tile
Hardibacker (in case there's damage to the walls)
Grout (unsanded for walls, sanded for the floor)
