Hi S. Steed,
My suggestion would be to measure the area you have then look online to see what fits. Then to find out what is available in your area, call or visit big box or kitchen & bathroom stores to see what they have in stock or what they can order. Every thing here - except for ads - is a someone sharing a DIY project. If you saw one in an ad, you would have needed to click on the ad to find out more details. I hope this helps you. Wishing you the best.
Hi, S. Steed!
By "seashell sink", do you mean the type that is imprinted like a seashell or one that is covered in seashells? If I'm thinking correctly, the sink will be sort of oval in shape and will need an oval shape cut into the counter so it drops in. Some sinks have clips attached to the underside that are tightened to the underside of the counter top and some do not. If it doesn't, run a bead of silicone for kitchen and bath areas along the top of the opening on the countertop, then drop the sink in. Once the silicone cures, it will hold the sink in place. I hope this helps - if not, post again and include a photo, if you can, so that we can give better suggestions!
Not sure what you are asking. You have a sea shell sink to install on a vanity? One from a pedestal? Or are you looking for a sea shell sink?
Do you have a standard pedestal sink now, and you want to replace it with a seashell shaped sink instead? Do you want to keep the pedestal look?
