    Hello,

    I have a shower in the basement on a concrete slab. The previous owner placed tile directly on the slab to the drain. Actually, the drain sits about a 1/4" above the tile.

    I would like to rip up the tile and walls then install a solid shower basin. Looking at the drain it appears to be 2" pvc with a black plastic ring around the top on the inside. Can I place the shower basin directly on the drainpipe with the proper drain adaptor?

    You may have to chop some concrete to get to the pipe. Most shower drains and current code is a 2" pipe. Yours maybe two 2"'s but the adapter used is 1.5" which is OK. This shower was probably built in the 1970-80's by the materials used and it was common to install it as you have it. Are there other fixtures such as a toilet? If you think the plumbing was installed when the home was built then there should be proper drainage and venting. One problem, quite often, a homeowner did the install and used an existing floor drain. These sometimes drain into a sump pump that get discharged outdoors, not the septic system. Something to look at.

    As for tiling, this John Bridge site is the best when it comes to "how to's" for shower pan builds and tiling. Most preformed shower pans will not fit the location to the floor drain and building one will probably be necessary.

    The house was built in 1977, there is a sink and toilet in the room now. No sump pump. If you look down the drain there is standing water about 4 inches down, because of that I assume there is a p-trap.

    I did find this basin,

    figured I could make the width of the shower to 32" and the basin should fit perfectly with the measurements I have.

    btw: nice Camaro

    The basin looks, maybe a little wiggle where the side walls may need to be moved slightly. Most likely your drainage system is good.

    The Camaro is my retirement toy. Sits in a storage unit most of the time. The wife wouldn't let me get a Harley. It is a beast, 455 HP and after I get it and she drove it once or twice she doesn't want to drive it. Then one day she sees a C7 Corvette and said this Camaro was a Corvette I'd drive it. Now she tells me.
