Make your Shower Handicapped Accessible

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 whom needed a walk in shower with a ramp for easy access for a quadriplegic member of their family.

Once there, I noticed some broken tiles that needed to be replaced as well.

Safety notice:
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.

Putty knife
Floor scraper
Grout sponge

Step 1: Demolition and Preparing the Surface

Due to the deadline to finish this project, I wasn't able to take pictures of the demolition phase, but I will be happy to respond any questions you might have.

This shower had double sliding aluminum and glass doors, they were removed just by removing seven screws and getting rid of the sealing silicone. 

Cover the drain with masking tape to avoid debris falling into it.

In order to make space for the ramp, the marble on top of the step had to be cut, this was made with the grinder with a diamond blade, this phase involves a lot of dust, protect your lungs by covering your nose.

The rest of the step was removed by removing the tiles with the sledgehammer and the chisel. The cinder blocks were easy to remove, because this shower was poorly built and it had a water filtration, thus the step was just being held by the tiles and the marble on top.

To make the slope for the ramp, you need to chisel away. Find the appropriate angle and chisel away until you have reached the desired angle. Watch out for flying debris.

The broken tiles on the back were removed and they revealed a water damaged hardibacker board, it was removed and the area cleaned and prepared to receive the new hardibacker.

Clean the old mortar and grout from the adjacent tiles with a little chisel or putty knife, make sure it is completely free of old adhesives.
