you have probably got some el-cheap-o shower base
from some hardware store for 200 bucks with the glass wall kit included
thats ok.....see them all the time
If you do this right the first time you are going to save yourself
a lot of misery and greif
the first thing you must do is USE A LEVEL to see if the base or floor
falling in any directioin....
You MUST level the base
or you could end up with a 1/2 inch
of water always standing in one of the corners not
wanting to flow into the drain like you want it to....
then you need to level up the base and its a good idea to
put some soupy concrete sand mix under the base to help level it up....
once you find your level groove for front back and center and have got it sitting in concrete.....then you can drill the
lip with a small drill bit and use some sort of brass drywall
screws to secure the base to the walls
sometimes its better to have the front lip off the ground a 1/2 inch
sitting in concrete if that makes it level
rather than to have a slope to the front of the ne-o-angle shower.
You can always shim up and hide the
concrete and gap in the front with plastic trim
also...if you dont make it at least close to level,
when you finally put up the
el-cheap -o glass shower doors and walls ,
it will be hell to pay to get them to sit correctly on the base....
you can end up with a 1/2 inch gap on some conrer
that you cant do a thing with...except fill in with a thick
load of silicone to keep it from leaking
