hi Rahul, you need 3 by 3 sq feet space for wc, as per layout you are getting it. i suggest you to avoid mirror in front of wc, as nobody wants to see themselves in that condition seeing themselves. also, door should open on other side so it will hide the wc. Your washbasin should be in right of counter as it give you more space to use for placing your things like trimming machine etc. for quartz go for mitter edge as it look thick without any extra line, which is most preferred today by Designers today. please prefer glass partition between washbasin and shower, as to segregate wet and dry area. and if you want to ask anything further or discuss about your design. thanks, Archiera Design, Delhi

also, avoid veneer in bathrooms as Veneer sheets are softer than laminate sheets. Once the polish layer wears off over time, the veneer becomes susceptible to abrasions. The veneer sheet may bubble or warp if moisture seeps into the core material or if the top layer is exposed to heat. So they are not great options for kitchens, bathrooms and other wet areas.

Hi Rohit, I will suggest you to go with a contrasting shade of charcoal black with some brass or mirror patterns.

the sink should be at 33" from the floor. your countertop height will depend on if you're using a top mounted or insert sink
