I have a cultured marble shower stall that the Silicone caulking looks bad on, black mildew behind the white caulking. I had this shower stall installed 2 years ago & it looks like crap already. Where it looks bad is along where the floor and walls meet. There is not a "pan" for the floor, it is a more flat cultured marble piece that has a rough non-slippery surface that the walls sit on.
I have removed all of the old silicone & was ready to put in new silicone. My dad says to use grout instead, that it will hold up better and be easier to install. I thought I had heard that grout was not waterproof?
My question is, can I use grout in this joint along the floor in the shower stall? Will it hold up? If so is there a type of grout that would work best?
I do hate working with silicone, it is such a mess & the stuff I worked all day to dig out was only there 2 years.
Thanks in advance!
