Plumbing – How to install this wall mount bathroom sink

There are three things you need to consider:

1. Support;
2. Support; and
3. Support!

You NEED to find solid framing, probably uprights studs. You need serious screws/lag bolts into those studs. The sink is sure to come with mounting instructions as to exactly how to attach, but framing is a key. Masonry hanging may be possible, but you will need very deep, serious anchors.

Many wall mount sinks can also get some extra support in the form of slender metal legs that help lift up front lip. A pedestal sink is also very compact and adds a center support. Finally there are corner sinks that rely on support from two walls.

Obviously there are a few other things, once you have solved that. Where do the supply lines come from? Where does the drain enter the wall/floor? You might avoid the skirt (if you want) if you can position the lines to make them appear symetrical, attractive, etc? What type of fittings do you think are acceptable to see (solid chrome or brass? braided flex? etc.). If you are certain they will be hidden, less of an issue.

Oh, by the way, if you don't have good SUPPORT, the pipes will eventually leak.

This will only work if the new sink (including the lip that sits on the counter) is larger than the old sink - it looks like your new sink is actually a bit smaller (13x18 vs 16x19.5) which means there will not be any surface area on the counter for it to rest on.

Lets say for a second you did find a slightly larger sink. You now need to consider the counter material. If it is a laminate counter you can easily enlarge the hole for the new sink, however if it is a stone like granite, you will need some specialized tools and know-how in order to enlarge the hole; it could end up being cheaper to just replace it.

You also need to consider how you will remove the old sink. If the new one is a fair bit larger you can just cut it out, but if margins are tight, you will need to very carefully break the old sink free without damaging the counter.
