As long as you are remodeling so the best way to do is ripping out everything and start from scratch

The slope can be changed by chiseling the old concrete and adding more if necessary.

What you should worry about is if the rubber membrane under the existing concrete is adequate and the drain is the right height for the extra amount.

Why waste time figuring things out. if your going to remodel do it right start from scratch and that way you can sleep with reasuration that the job was done right.

Hi,

Always tear out all the existing. And start from from the raw floor and studs. This wsy all the plumbing in the floor and wall can be checked and brought up to new. Then the ptober rubber membrain can be indtalled on the floor and up part of the walls.

Then cement board can be etc installed on the walls. And a new concrete pour on the shower floor. Good luck.

Hi Jeanette,

I would remove it all so you do not have any chance of future water leaks. Install a Schluter shower pan and Kerdi walls by a qualified installer.

You will then have a water-proof shower system.

Rip it out if you are removing the drywall around the shower base,

It's very likely the base is sealed to the wall .

And if you are doing a mayor renovation in the washroom .

It would be best to remove it , and use a better base then concrete .
