If it was me, I would centre it and only silicone the back. I understand your concerns about water going down the side. Realistically, though, as you will only be washing your hands and maybe teeth in it, there is unlikely to be much water gushing about. To detract from the fact there is not as much space on either side of sink, I would have carpenter either wall mount or put legs on the cabinet so there is space underneath and the unit doesn't look too chunky!

Looking for lighting suggestions for 3' 10" (46") x 7'10" powder room with 9 ft ceilings. I've found several great examples but not sure of the dimension/scale. With 9' ceiling, would you go with hanging pendant/s or sconces? There is a also huge 3x5 window as well, so plenty of natural light. Planning on a floating vanity the width of the wall as shown here / Single pendant https://www.houzz.com/photos/the-west-hampton-beach-style-powder-room-phvw-vp~97611787 Two Pendants: https://www.pinterest.com/pin/213428469829037852/ https://www.houzz.com/photos/manhattan-beach-modern-farmhouse-farmhouse-powder-room-los-angeles-phvw-vp~117249326 Sconces: https://www.houzz.com/photos/newport-beach-peninsula-point-contemporary-powder-room-orange-county-phvw-vp~121605490 Many Thanks!

hi, I am using the henley fog floor tiles on my bathroom floor, the unit is a roper rodes combined vanity and wc in pebble grey. I am struggling to find a suitable wall tile to match up with these, the wall tiles will just go in the shower area, not all over the walls. Any suggestions for me? Thanks, Fin

nobody has any suggestions for me?
