I want to know how to seal a shower wall and floor the wall is fiberglass and the floor is cement?
Answers:
first of all remove any old caulking. all of it needs to be removed. if there is any black stuff spray it with a bleach / water solution. it may take a 2nd spray. rinse well. I use acetone to clean all residue of the old caulking and other contaminets. this is stinky stuff but it works great. a little bottle goes a long way. then use Silcone, it remains flexiable. the smaller the bead the better. you can smooth it slightly with your finger and clean it off with the acetone.

SILICONE
Most use a shower pan so that the wall will rest in a lip to keep water from getting behind the wall. Maybe tile the floor and cove it with the same tile.
silicone caulk make sure it is 100% silicone usually the most expensive they have
Check with the guys at Lowe's or Home Depot. You should be able to get everything you need for about $48.68.
install a pan!!
Phenoseal caulk. Remove and clean the area prior to putting the new caulk down.
