How to install an undermount sink to your bathroom counter top.
Installing an undermount sink is a process that is done by many different trades. Sometime the sink is factory installed and comes as one big piece. Other times the sinks are installed by the counter top installers.
Or later by the plumber.
Over the years I have seen all sorts of techniques and this one here is my favourite. I would like to get some feed back from you pros as to how it might be improved.
For one I love the ease of install. This is a job I can do alone but one made easier with my helper. We installed both sinks in 30 minutes total. We used 10' of stainless steel strapping and 1/3 tube of clear silicone.
We start by setting two straps to the side of the vanity or plywood support of the counter top.
Then we apply clear silicone and hold the sink in position while I screw down the two straps. We are looking for light pressure here so we can have a little play above to fine tune the sinks position.
Once set we leave the sink to set up overnight.
The plumber will come and have the sinks set and will be able to hook it all up!
We have found that some sinks and vanity designs make for a problem install and the faucet needs to go in first. Most projects are smooth as silk and this rig works well.
I will back off the steel straps a hair today and get some kind of bumper between the sink and the strap.
What other techniques do you guys use to install your sinks?
