"TRENDY" is what I think. WHY, would any company want to make a sink in the shape of a clam molded into your not so easy to renovate bathroom countertop? Your stuck when you finally come to your senses and realize it is an eyesore. The Roasting B4 Toasting Trailer Park will give you some ideas that would work and or what to do instead.
DO NOT START PROJECTS EXPECTING PERFECTION
This project took me awhile as I started the project intending to do the DIY concrete counter top using the feather finish concrete. I ended up doing the faux marble top over what was left of the concrete I previously applied. I tried to like the concrete but it was too hard to get smooth and sometimes the sanding made parts of the concrete come off. I think if I was not trying to make it absolutely perfect it would have been okay but I kept sanding and sanding. It just never got smooth enough for my taste. That is when I decided to go with doing a faux marble top. I actually used some of the grey wall paint as part of the marble finish so that it would tie into the wall. Also, since I did not like the way the concrete looked on the back-splash I decided to tile this to match the tile that was already on the bathtub. As it turns out I did not like any of these ideas so I am going to explain what to do instead.
WHAT I SHOULD HAVE DONE IN THE FIRST PLACE!
I searched high and low on the internet for the cheapest solution that would help me rid our house of this outdated clamshell sink. But the solutions were either get a new high price countertop with sinks already molded in or a new countertop where we had to have it custom cut for the the sink holes. There were other options as well but I was unsure if I could do it or if it would even look good. I ended up not liking most of those so I am going to show what I should have done below:
DO NOT DO A CONCRETE COUNTERTOP OR FAUX MARBLE FINISH
NO! I don't think it looks good! The concrete countertops were not smooth even after sanding and break down easy when sanding. Have you ever sanded concrete? It is not easy and is time consuming. I also do not like how cheap the faux marble looks. My problem is that I was expecting perfection. Remember guys it is DIY for a reason. I think it looks cheap. I would advise looking into other DIY's when you are doing countertop projects.
