Modifying new kitchen sink
tegwin - 15/12/10 at 10:30 PM

Just about to fit a new kitchen sink... was a reasonably cheap sink... only has a tiny bit of bitumin sound deadening on the base of the main sink.... Im thinking the sink is going to be very noisy and get a lot of condensation underneath it...


I am tempted to spray it with expanding foam on the under-side and then carve it back so I have an even coating of about 1.5" over the entire base including the draining board...

Do we recon that will actually help make the thing quieter and feel more "expensive"...

Any downsides to doing this?

Edit so say, its a franke stainless steel jobbie....

put more bitumen on it , you can buy sheets from paint and panel suppliers. How much noise are you expecting once water has filled the bottom you will hardly notice as the weight will take out any flexing it may have

Its quite a large basin... and thin steel, so it makes quite a lot of noise when you "put" stuff in it... my bedroom is over the kitchen.... so I am doing anything I can to reduce the noise I sleep veerrry lightly


The last sink I bought (which was a lot more expensive) had a layer of heavy rubberised foamy type stuff moulded around the base of the stainless...

99% of expanding foam is not waterproff?
so i would not use it

paint it with underseal will work

expanding foam isnt closed cell so bad idea as it will soak up water like a sponge. if it was me i would just fit it and forget, i didn't know sinks had to be quiet.

i thought frankys were a good brand, so if thats as much as they put on it?,,,,,,,,,

How about a bit of adhesive roof flashing if you must?

Never even thought about it either. Always wondered what that crappy black stuff on the bottom is that always falls off! lol!

Something else to worry about now!!!

How often is 'sink underside condensation' a problem? Again, not something I've ever noticed!

I rarely fill my sink with cold water (ever?). It's only ever hot and 99% that's in a washing up bowl!


Do you bathe in it?

drink more wine = sleep less lightly

then get a life......

If you fit a dishwasher you don't have to worry about it

If concerned the bitumen pads for cars will do. If you think there is too much flex then use some tigerseal/whatever and glue some 18mm battens to the large area (assuming flat, may need carving) Have done this under the drainers if they flex to much.
Incidently, I have given up on the clips to hold sinks in place, now use a good bead of tigerseal, drop the sink in, leave a cuple of packs of tiles in overnight to weigh it down and job done. No faff, waterproof join that causes no problems (oldest one about 10 years now) and no useless clips.

I got a butler sink, only noise I ever hear from it is when something fell in and smashed, (my favourite glass) then I wished I had a nice bouncy stainless one LOL

how far is the modifying going to go?

maybe some underseal, and while your under there, why not fit some blue neons? maybe some heatwrap around the taps?

or even go for a big bore plug hole

I presume the 'heavy rubberised foamy type stuff' was either a bitumin or neopreame based stuff?

Some more sheet bitumin sounds good to me (ignore that pun) its not like your aiming for good power to weight or handling!

I fitted a Franke 1 and 1/2 bowl sink/drainer in our kitchen and can't say I even considered the noise or condensation side of things. It's flexy as hell when it's not fitted, but once clipped and sealed in place it's pretty solid TBH.

Did you get the worktop jointing sorted out that you asked about previously?

the solution is to fit a pair of noise cancelling speakers, waterproof ofcourse, next to the sink.

I will now have sleeples nights worrying if there is condensation on the underside of my sink - THANKS

I'm thinking we need some photos of this DIY masterpiece in progress

Frankie IS a good brand, so i wouldnt worry about noise. Condensation isnt an issue, its the cold pipe that would be a problem first.

Ok... You asked for it lol... will put up a new thread in a sec

If you do the washing up you wont have to worry about the noise when trying to sleep.


Personally id just hoy the sink in as it is and get the kitchen finished, stop faffing about!
