Semi Recessed Basins - what gap behind basin to wall? Tight or a Gap

7 years ago
last modified: 7 years ago

hi

I am installing a vanity unit in a newly created space with a toilet at one end.

Its 900 wide by 510mm deep.Depth being from the whiteset plaster to edge of door jamb

Max expected stone bench depth after

13mm Glass Splash back tiles and glue

77mm 67mm architrave + 10mm architrave setback

=420mm possible maximum stone bench depth

(its not built so we could make it narrower, however we are trying to maximise the bench depth as we intend to also have shaving cabinets overhead and want storage underneath)

Cosmetically though where do people generally like to see the back of the basin end up?

Option 1

Tight to the wall or the tiles



This normally means one has to cut down the bench to 300 something.

Option 2

a Gap

but what size?

below the image in the foreground's Gap to back of wall from basin is 85mm, the next basin (rectangular basin in the middle of the 3) is 50mm



the next two images i found on the net and am not sure the size other than to illustrate a gap





two images i found in another Houzz thread

the user says this bench is 440mm deep







the below one seems like only a small 30mm gap,



i think 30mm is about the smallest you want to go otherwise it looks like you made an error and didnt quite get it flush. Plus its harder to clean.

If I stick to the 420mm deep bench i calculate with the Liano Nexus from Caroma

I current end up with a 125mm gap

If i go with the Raymor Aquamarine SC

http://www.raymor.com.au/pdf/Aquamarine%20Semi-recessed%20Basin%20(23.06.2019%209-34-29).pdf

I calculate i end up with a 80mm gap (being 420mm bench depth minus the non protruded part of the basin @ 340 = 80)

What do people think?
