Correct. By adding additional 8 seats in SL, they have compromised on the wash basin and toilet space areas. Highly inconvenient for passengers in seats 1-8 and then 73-80 who are seated in the last bay especially when the wash basin leaks. As you rightly pointed out, have observed that the LHB Wash basins are slightly smaller and hence even a small wash of face, water gets spilled outside.
