The LaSalle Bristol Single Bowl RV Bathroom Sink # 34416166PW is the white version of your LaSalle Bristol BPC 61A Model 166 sink. It has the same overall dimensions 15-3/4" x 12-3/8" and is designed for the same undermount installation.

The primary difference is the color:

Your original sink: Parchment 16166PP
Replacement in Parchment: # 34416166PP
Replacement in White: # 34416166PW

Has your original sink remained factory installed since new or has it ever been replaced?

Hi James, You raised a good question. Thank you for confirming! Yes, my "existing" sink is the original from the Airstream factory when I purchased the trailer. I purchased it new in the later part of 2000. I am the original and only owner. After 26 years it now has a hairline crack in the bowl. My wife noticed it and brought it to my attention. It doesn't leak yet. However, I needed to replace it before it got worse because I maintain the trailer well maintained and in shape so we can continue to enjoy without any worries. At first, I thought that because many years had gone by that my chances of finding a replacement sink would be slim to none. I was pleasantly surprised during my internet search to find that you have this part in stock! I have moved forward to purchase the part. It will be a nice little change to have white now. Thank you all for stocking it! As always, you all provide good parts, service & great information in written and video.

@NickG I installed two of these sinks on our vessel. They are drop in sinks not undermount. You will need to caulk them before installing and after installing. They do have screw in mounts underneath but found them to be a pain. The sinks have a lip and are not flush mount which in our case is best to contain water. They worked out great for us. Hope you successfully installed and enjoy. Lori El Gato sailing catamaran vessel

@NickG 26 years with the same Airstream, that's awesome! It sounds like you and your wife have really taken care of it over the years and she props to her for finding that crack before it turned into a leak. I'm glad we were able to track down the same Model 166 sink after all this time and I think the white will be a nice little update too. Thanks for the kind words, we really appreciate it! After 26 years together, I have to ask what's been your favorite trip in the Airstream?
