I love a good design challenge & you CAN make this sink work for you! I don't know what your design aesthetic is, but I see this working in a contemporary or transitional style bathroom. For the sink, choose an under-mounted model & place it beneath a 1-1/4" thick, solid surface countertop made of engineered quartz such as Silestone or Zodiaq. Mount your faucet to the wall & you've made a design statement! Cabinets doors can be slab for contemporary, shaker for transitional. Just be sure that your vanity is deep enough to accommodate this sink. You can always order a kitchen sink base & modify it for the bathroom. Standard rule of thumb: - kitchen cabinets are typically 24" deep & 36" high - bathroom cabinets are 21" deep & 34" high Good luck! ~LMM

Ok, leaving the laundry as is coz it's existing I'll focus on the bathroom... - not sure if the opening from the laundry to bathroom is existing too, but if not I would consider moving the doorway 'down' closer to the wall, which would make the space more workable (p.s. a cavity sliding door would work best here) - I would add a highlight window say 04x21 on the 'left'/bath wall with frosted glazing for privacy and would replicate that highlight window with clear gazing above the door/wall separating the laundry and bathroom - if this isn't the main bathroom but an additional one for guests, do you really need a bath in there?... I would swap location of the bath & vanity and have a double walk-in shower along the 'top' 2m wall, with a glass shower screen to maintain light and openness... also better for elderly guest than climbing into/over bath hob - I would put the vanity, a floating one to maintain openness, on the 'left' wall where the bath was, and I would still keep the window to the street at the 'bottom' but maybe centred on the wall could be better Hope that makes sense, let me know what you think and feasibility

we need a floor plan with dimensions to offer any worthwhile suggestions..

Thanks oklouise! So many options to consider - thanks for your time :) I think the best one for us is to make use of the weird alcove space and to use that empty wall as laundry cupboard storage. If all the cupboards are shifted there, then I wonder if there is room in the current laundry for a corner shower, toilet and a sink counter that extends over the top of the washing machine? I have, however, allowed for small cupboards on either side of the window. I tried to do such a plan on the ikea bathroom planner (except I couldn't figure out how to put in a sink and counter top that covers the WM, so that's still to be added). How much leg room do you normally allow for the toilet? Maybe it's still too squishy though??
